determine if each of the numbers below is a solution to the inequality 3x-2<2-2x

Answers

Answer 1

The solution set of the inequality 3x-2 < 2-2x is:

(4/5, ∞)

Which numbers are solutions for the inequality?

To find this we need to isolate the variable in the inequality.

Here we have:

3x - 2 < 2 - 2x

add 2x in both sides and add 2 in both sides, then we will get:

3x + 2x < 2 + 2

5x < 4

Now we can divide both sides by 5 to get:

x < 4/5

That is the inequality solved.

Then the solution set of the inequality is:

(4/5, ∞)

The set of all real numbers larger than 4/5.

Triangle ABC has vertices


A(-3, 3), B(2, 4), and C(-2,


2) and is translated


according to the rule:


(x, y) –> (x+2, y-4).


What are the coordinates


of the vertices of the


translated figure?

Answers

The coordinates of the translated triangle A'B'C' are: A'(-1, -1), B'(4, 0), and C'(0, -2).

To find the coordinates of the vertices of the translated figure, we simply apply the given translation rule to each vertex of the original triangle.

For vertex A(-3, 3):
(x, y) --> (x+2, y-4)
(-3, 3) --> (-3+2, 3-4)
(-1, -1)

So, the translated coordinates of vertex A are (-1, -1).

For vertex B(2, 4):
(x, y) --> (x+2, y-4)
(2, 4) --> (2+2, 4-4)
(4, 0)

So, the translated coordinates of vertex B are (4, 0).

For vertex C(-2, 2):
(x, y) --> (x+2, y-4)
(-2, 2) --> (-2+2, 2-4)
(0, -2)

So, the translated coordinates of vertex C are (0, -2).

Therefore, the vertices of the translated triangle are A'(-1, -1), B'(4, 0), and C'(0, -2).

we introduced wind chill as a way of calculating the apparent temperature a person would feel as a function of the real air temperature, I, and V in
mph. Then the wind chill (i.e., the apparent temperature) is:
W(T, V) = (35.74 + 0.6215T - 35.75V^0.16) / 0.4275TV^0.16
(a) By calculating the appropriate partial derivative, show that
increasing T always increases W. (
b) Under what conditions does increasing V decrease W? Your
answer will take the form of an inequality involving T.
(c) Assuming that W should always decrease when V is in- creased, use your answer from (b) to determine the largest domain in which this formula for W can be used.

Answers

a) The partial derivative of W with respect to T is always positive, which means that increasing T always increases W.

b) Increasing V decreases W if V is greater than

[tex]((0.8T - 0.6215) / 5.71)^{(1/0.16)} .[/tex]

c) The largest domain in which the inequality derived in (b) holds true is:

T > 0.7769. This means that the wind chill formula can be used only for

air temperatures above 0.7769 degrees Fahrenheit.

(a) To show that increasing T always increases W, we need to calculate the partial derivative of W with respect to T and show that it is always positive.

∂W/∂T = [tex]0.6215/0.4275V^{0.16} - (35.75V^{0.16})/0.4275TV^{0.16}^{2}[/tex]

Simplifying this expression, we get:

∂W/∂T = [tex]1.44(0.6215 - 0.0275V^{0.16T}) / V^{0.16}T^{2}[/tex]

Since 1.44 and[tex]V^{0}.16T^{2}[/tex] are always positive, the sign of the partial derivative depends on the sign of[tex](0.6215 - 0.0275V^{0.16T} ).[/tex]

Since 0.0275 is always positive and [tex]V^{0.16T}[/tex] is also always positive, we see that [tex](0.6215 - 0.0275V^{0.16T} )[/tex] is always positive.

(b) To find the conditions under which increasing V decreases W, we need to calculate the partial derivative of W with respect to V and show that it is always negative.

∂W/∂V = [tex](-35.750.16V^{(-0.84)} (35.74+0.6215T-35.75V^{0.16} )-0.6215V^{(-0.16} ))/0.4275TV^{(0.16)}[/tex]

Simplifying this expression, we get:

∂W/∂V = [tex]-0.16(0.6215+5.71V^{0.16-0.8T} ) / TV^{0.84}[/tex]

The sign of the partial derivative depends on the sign of [tex](0.6215+5.71V^{0.16-0.8T} ).[/tex]

If [tex]0.6215+5.71V^{0.16-0.8T} < 0[/tex], then the partial derivative is negative and increasing V decreases W.

Solving this inequality for V, we get:

[tex]V > ((0.8T - 0.6215) / 5.71)^{(1/0.16)}[/tex]

(c) Assuming that W should always decrease when V is increased, we need to find the largest domain in which the inequality derived in (b) holds true.

Since the expression inside the parentheses must be positive for a real solution, we have:

0.8T - 0.6215 > 0

T > 0.7769

Calculate the derivative of the following function, 4 y=sin(cos (8x)) ) Find the critical points of the following function f(x) = xVx+6"

Answers

The critical points of f(x) are x = -3 and x = 4.

Derivative of 4y = sin(cos(8x)):
We can find the derivative of the given function using the chain rule of differentiation. Let u = cos(8x), then we have:
y = sin(u)
dy/du = cos(u) (derivative of sin(u))
du/dx = -8sin(8x) (derivative of cos(8x) using chain rule)
dy/dx = dy/du * du/dx = cos(cos(8x)) * (-8sin(8x))
Therefore, the derivative of 4y = sin(cos(8x)) is:
dy/dx = -32sin(8x)cos(cos(8x))
Critical points of f(x) = x√(x+6):
To find the critical points of f(x), we need to find where the derivative of the function is equal to zero or undefined.
f(x) = x√(x+6)
f'(x) = (√(x+6) + x/2√(x+6))
To find the critical points, we need to set f'(x) equal to zero and solve for x:
(√(x+6) + x/2√(x+6)) = 0
Multiplying both sides by 2√(x+6), we get:
2x + 6 = -x√(x+6)
Squaring both sides, we get:
4[tex]x^2[/tex] + 24x + 36 = [tex]x^3[/tex] + 6[tex]x^2[/tex]
Rearranging, we get:
[tex]x^3[/tex] + [tex]2x^2[/tex] - 24x - 36 = 0
We can solve this cubic equation using numerical methods or by factoring.

By testing values, we can see that x = -3 is a root of the equation. Dividing the equation by (x+3), we get:
[tex]x^2[/tex]- x - 12 = 0
This quadratic equation can be factored as (x-4)(x+3) = 0.

A home repair crew charges $75 dollars per day plus a $250 service fee. the total amount the home repair crew charges this client is $925.how many days did the crew work?

Answers

The home repair crew worked for 9 days.

What is the duration of the home repair crew's work to charge $925?

To determine the number of days the home repair crew worked for, we can use algebra. Let's assume that the number of days they worked for is represented by "d". We know that they charge $75 per day plus a $250 service fee, so we can set up the following equation:

75d + 250 = 925

Simplifying the equation, we get:

75d = 675

Dividing both sides by 75, we get:

d = 9

However, we need to keep in mind that the $250 service fee is a one-time charge, not a daily charge. So we need to subtract that from the total amount to get the actual amount charged for the days worked:

925 - 250 = 675

Dividing 675 by the daily rate of $75, we get:

675 / 75 = 9

Therefore, the home repair crew worked for 9 days.

Answers

We can use the point-slope form of the equation of a line to find the equation of the tangent line.

How to find the equation of the line that is tangent to circle A from point C (2, 8)?

To find the equation of the line that is tangent to circle A from point C (2, 8), we need to first find the point of tangency, which is the point where the line intersects the circle.

Point C (2, 8) is outside the circle, so the tangent line will be perpendicular to the line connecting the center of the circle to point C and will pass through point C.

Step 1: Find the center of the circle

The center of the circle A is at (6, 5).

Step 2: Find the slope of the line connecting the center of the circle to point C

The slope of the line connecting the center of the circle (6, 5) and point C (2, 8) is:

m = (8 - 5) / (2 - 6) = -3/4

Step 3: Find the equation of the line perpendicular to the line from Step 2 passing through point C

The slope of the line perpendicular to the line from step 2 is the negative reciprocal of the slope:

m_perp = -1 / (-3/4) = 4/3

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line:

y - 8 = (4/3)(x - 2)

Simplifying, we get:

y = (4/3)x + 4.67

So the equation of the line that is tangent to circle A from point C (2, 8) is y = (4/3)x + 4.67.

To find the missing ratios, we need to set up proportions using the given information.

13.5 square meters is covered by 3 liters of paint, so we can write:

? = (13.5 x 1) / 3

? = 4.5

So, 4.5 square meters can be covered by 1 liter of paint.

To find the last missing ratio, we can use the same method:

13.5/3 = ?/10

10 x 13.5 = 3 x ?

Substituting [tex]x^2 + y^2 = z^2[/tex] into[tex]x^2 + y^2 + z^2 = 25[/tex], we get [tex]2z^2 = 25[/tex],

which gives z = ±5/√2.

[tex]x^2 + y^2 = 3z^2 and x^2 + y^2 + z^2 = 25:[/tex]

Substituting[tex]x^2 + y^2 = 3z^2[/tex]into [tex]x^2 + y^2 + z^2 = 25[/tex], we get [tex]4z^2 = 25[/tex],

Answers

If a teacher has an annual salary of 98,500, the teacher makes  $947.12 per biweekly period.

To calculate the teacher's biweekly salary, we need to divide their annual salary by the number of weeks in a year, and then divide that result by 2 (since there are 2 weeks in a biweekly period).

There are a few different ways to approach this calculation, but one common method is to use the following formula:

Biweekly Salary = (Annual Salary / Number of Weeks in a Year) / 2

Using this formula, we can calculate the teacher's biweekly salary as follows:

Answers

By using the method of undetermined coefficients, The general solution is y = ae^(4x)cos(3x) + be^(4x)sin(3x) + (7/2cos(3t) + 5/2sin(3t))e^(4t). The solution to the initial value problem is y = 3e^(2x) + 14e^(4x) - 3e^(3x).

By using the method of undetermined coefficients, the associated homogeneous equation is y''-8y'+297=0, which has the characteristic equation r^2-8r+297=0. The roots of this equation are r=4+3i and r=4-3i, so the homogeneous solution is yh=a*e^(4x)cos(3x)+be^(4x)*sin(3x).

To find the particular solution, we make the ansatz yp = (Acos(3t) + Bsin(3t))e^(4t), where A and B are constants to be determined. Substituting this into the differential equation, we get

y" - 8y' + 297 = (16A - 18B)e^(4t)cos(3t) + (16B + 18A)e^(4t)sin(3t)

On the right-hand side, we have 48e^4tcos(3t) + 80e^4tsin(3t), which suggests setting

16A - 18B = 48, and

16B + 18A = 80

Solving these equations simultaneously, we get A = 7/2 and B = 5/2. Therefore, the particular solution is

yp = (7/2cos(3t) + 5/2sin(3t))e^(4t)

And the general solution is

y = yh + yp = ae^(4x)cos(3x) + be^(4x)sin(3x) + (7/2cos(3t) + 5/2sin(3t))e^(4t)

For the second problem, the associated homogeneous equation is y''-6y'+8y=0, which has the characteristic equation r^2-6r+8=0. The roots of this equation are r=2 and r=4, so the homogeneous solution is yh=ae^(2x)+be^(4x).

To find the particular solution, we make the ansatz yp = Ce^3x, where C is a constant to be determined. Substituting this into the differential equation, we get

y" - 6y' + 8y = 9Ce^3x - 18Ce^3x + 8Ce^3x = (8C - 9C)e^3x = -C*e^3x

On the right-hand side, we have 3e^x, which suggests setting -C = 3. Therefore, the particular solution is

yp = -3e^(3x)

And the general solution is

y = yh + yp = ae^(2x) + be^(4x) - 3e^(3x)

To find the values of a and b, we use the initial conditions

y(0) = a + b - 3 = 14

y'(0) = 2a + 4b - 9 = 29

y''(0) = 2a + 8b = 25

Solving these equations simultaneously, we get a = 3 and b = 14. Therefore, the solution to the initial value problem is

y = 3e^(2x) + 14e^(4x) - 3e^(3x)

Calculate the means-to-MAD ratio for the two types of monkeys.

What inference can be made about the weight of both types of monkeys? Explain.

Answers

Howler monkeys are heavier on average than spider monkeys (17.75 lbs vs. 11.25 lbs).

How to solve

Calculate the mean:

Some of the weights divided by the number of monkeys

Calculate the MAD:

Find the absolute deviation (difference) of each weight from the mean

Calculate the average of these deviations

Mean Howler Monkey = (16+17+18+18+18+20+22+23)/8 = 142/8 = 17.75 lbs

Mean Spider Monkey = (8+10+10+11+11+12+14+14)/8 = 90/8 = 11.25 lbs

Now, we calculate the MAD for each type of monkey:

MAD Howler Monkey=  1.875 lbs

MAD Spider Monkey=  1.5625 lbs

we calculate the means-to-MAD ratio for both types of monkeys:

Howler Monkey: Mean/MAD = 17.75/1.875 = 9.466

Spider Monkey: Mean/MAD = 11.25/1.5625 = 7.2

Inference:

Howler monkeys are heavier on average than spider monkeys (17.75 lbs vs. 11.25 lbs).

The means-to-MAD ratio shows that howler monkeys have more consistent weights (9.466) compared to spider monkeys (7.2), as a higher ratio indicates less variability in weights.

Find the absolute maximum and minimum values of f(x,y) = x^2 + 2y^2 on the square [0,1] x [0,1]

Answers

Answer:

The maximum is when both X and y = 1.The maximum value of the function is 3.When both X and YY are equal to 0, the minimum value is 0

The absolute maximum value is 3 and the absolute minimum value is 0.

To find the absolute maximum and minimum values of f(x,y) = x^2 + 2y^2 on the square [0,1] x [0,1], we need to consider both the interior and the boundary of the square.

First, check for critical points in the interior by finding the partial derivatives and setting them equal to zero:

fx = 2x and fy = 4y

Setting them equal to zero, we have:
2x = 0 => x = 0
4y = 0 => y = 0

The only critical point in the interior is (0,0).

Next, evaluate f(x,y) on the boundary of the square [0,1] x [0,1]. The boundary consists of four segments: x=0, x=1, y=0, and y=1.

1. x=0: f(0,y) = 2y^2 (for y in [0,1])
2. x=1: f(1,y) = 1 + 2y^2 (for y in [0,1])
3. y=0: f(x,0) = x^2 (for x in [0,1])
4. y=1: f(x,1) = x^2 + 2 (for x in [0,1])

Now, compare the values of f at the critical point and boundary points to find the absolute maximum and minimum:

Absolute minimum: f(0,0) = 0
Absolute maximum: f(1,1) = 3

So the absolute maximum value is 3 and the absolute minimum value is 0.

Write exponential functions given the following scenarios:
1. a business had a profit of $35,000 in 1998 that increased by 18% per year. write the equation to model the
situation. find the profit of the company after 8 years.

2. you buy a used truck for $4,000. the value of the truck depreciates at a yearly rate of 12%. write the equation to model the situation. find the value of the truck after 6 months.

3. between 1970 and 2000, the population of a town increased by approximately 2.5% each year. in 1970 there were 600 people. write the equation to model the situation. find the population of the city in 1999.

Answers

The profit of the company after 8 years is approximately $105,085.11.

The value of the truck after 6 months is approximately $3,677.49.

The population of the city in 1999 is approximately 1,457.66 people.

How we write the exponential functions?

Let P(t) be the profit in year t, where t is the number of years after 1998. The initial profit in 1998 is $35,000.

The profit increases by 18% per year, which means the profit at time t is 1.18 times the profit at time t-1. Therefore, the equation to model the situation is: [tex]P(t) = 35000 * 1.18^t[/tex]

To find the profit of the company after 8 years:

[tex]P(8) = 35000 * 1.18^8[/tex] = $105,085.11

Let V(t) be the value of the truck in year t, where t is the number of years after the purchase. The initial value of the truck is $4,000.

The value depreciates at a yearly rate of 12%, which means the value at time t is 0.88 times the value at time t-1. Therefore, the equation to model the situation is: [tex]V(t) = 4000 * 0.88^t[/tex]

To find the value of the truck after 6 months (0.5 years):

[tex]V(0.5) = 4000 * 0.88^0^.^5[/tex] = $3,677.49

Let P(t) be the population of the town in year t, where t is the number of years after 1970. The initial population in 1970 is 600.

The population increases by 2.5% per year, which means the population at time t is 1.025 times the population at time t-1. Therefore, the equation to model the situation is: [tex]P(t) = 600 * 1.025^t[/tex]

To find the population of the city in 1999 (29 years after 1970):

[tex]P(29) = 600 * 1.025^2^9 = 1,457.66[/tex]

(07. 03 MC)



Chang has 2 shirts: a white one and a black one. He also has 2 pairs of pants, one blue and one tan. What is the probability, if Chang gets dressed in the dark, that he winds up wearing the white shirt and tan pants? Show your work

Answers

Question 1: The probability of picking 1 almond cookie followed by another almond cookie is 1/5.

Question 2: The probability of drawing 2 blue marbles in a row is 1/4.

Question 3: The probability of Chang wearing the white shirt and tan pants is 1/4.

In the problem, the chef draws two cookies without replacement from a box containing six cookies of three different types. The probability of picking one almond cookie followed by another almond cookie can be found by using the multiplication rule of probability.

The probability of picking the first almond cookie is 3/6, and since the first cookie is not replaced, there are now only 2 almond cookies left in the box out of a total of 5 cookies. Therefore, the probability of picking another almond cookie is 2/5. Using the multiplication rule, we multiply these probabilities together to get:

P(almond, then almond) = (3/6) x (2/5) = 1/5

In the problem, Peter draws two marbles randomly from a bag containing three different colors of marbles. The probability of drawing two blue marbles in a row can be found by using the multiplication rule of probability again.

The probability of drawing a blue marble on the first draw is 4/8, and since the marble is replaced, there are still 4 blue marbles left out of a total of 8 marbles. Therefore, the probability of drawing another blue marble on the second draw is also 4/8. Using the multiplication rule, we multiply these probabilities together to get:

P(blue, then blue) = (4/8) x (4/8) = 1/4

In the problem, Chang has two shirts and two pairs of pants, and he chooses one of each at random to wear.

The probability of him choosing the white shirt is 1/2, and the probability of him choosing the tan pants is also 1/2. Using the multiplication rule, we multiply these probabilities together to get:

P(white shirt and tan pants) = (1/2) x (1/2) = 1/4

Answers

The distance between the lions and the monkeys is 64 feet.


We can set up a proportion to find the distance between the lions and monkeys. Here's the step-by-step explanation:

1. Proportion: Since the path from zebras to monkeys is parallel to the path from tigers to elephants, we can set up a proportion using the given distances: 52/78 = x/96.

2. Cross-multiply: To solve for x, we can cross-multiply: 52 * 96 = 78 * x, which simplifies to 4992 = 78x.

3. Solve: Now we just need to solve for x. Divide both sides of the equation by 78: x = 4992 / 78. This gives x ≈ 64.

So, the distance between the lions and the monkeys is approximately 64 feet.

Which is the simplest formula for working out probability

Answers

The simplest formula for working out probability is the following:

Probability (P) = Number of favorable outcomes (F) / Total number of possible outcomes (T)

In this formula, the probability of an event occurring is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is a measure of the likelihood or chance of an event occurring. It is represented as a value between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event.

To calculate the probability, you need to determine the number of favorable outcomes, which are the desired outcomes or the outcomes you are interested in. Then, you divide that by the total number of possible outcomes, which is the number of equally likely outcomes in the given situation.

The ordered pairs that satisfy the function is B)(0,20) and D)(10,-20).

What is function?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Here the given function is y=-4x+20.

Now put x=6 and y=4 then,

=> 4=-4(6)+20

=> 4 = -24+20

=> 4 ≠ -4.

Then the coordinate (6,4) dost not satisfy the function.

Put x=0 and y=20 then,

=> 20 = -4(0)+20

=> 20= 0+20

=> 20=20

Hence the coordinate (0,20) satisfy the function.

Now put x=-4 and y=20 then,

=> 20 = -4(-4)+20

=> 20 = 16+20

=> 20 ≠ 36

Hence the coordinate (-4,20) does not satisfy the function.

Now put x=10 and y=-20 then,

=> -20 = -4(10)+20

=> -20 = -40+20

=> -20=-20

Then the coordinate (10,-20) satisfy the function.

Hence the ordered pairs that satisfy the function is B)(0,20) and D)(10,-20).

PLEASE SHOW ALL YOUR WORK AS NEATLY AS POSSIBLE: 1) Given f(x) = 3sqrt(x + 2)^2 a) Find the derivative, f'(x). b) Solve f'(x) = 0

Answers

The only critical point of f(x) is x = -2.

a) To find the derivative of f(x), we can use the chain rule and the power rule of differentiation.

f(x) = 3sqrt(x + 2)^2

f'(x) = 3 * 2 * sqrt(x + 2) * (x + 2)^1/2-1 * (1)

Applying the power rule, we simplify the expression as:

f'(x) = 6(x + 2)^1/2

Therefore, the derivative of f(x) is f'(x) = 6(x + 2)^1/2.

b) To solve f'(x) = 0, we set f'(x) equal to zero and solve for x:

f'(x) = 6(x + 2)^1/2 = 0

Dividing both sides by 6, we get:

(x + 2)^1/2 = 0

Squaring both sides, we get:

x + 2 = 0

Subtracting 2 from both sides, we get:

x = -2

Therefore, the only critical point of f(x) is x = -2.
