Evaluate the following expressions. Your answer must be an angle -z/2 S 0 S in radians, written as a multiple of r. Note that r is already
provided in the answer so you simply have to fil in the appropriate multiple. E.g. if the answer is /2 you should enter 172. Do not use decimal answers.
Write the answer as a fraction or integer
Sin^-1(sin((-5t-6)

Answers

The given expression is sin⁻¹ (sin((-5t-6)). Since the argument of sin⁻¹ and sin is the same, we can simplify the expression as follows:
sin⁻¹ (sin((-5t-6))) = -5t-6
OR, -5t-6 = (-2π/π)(-5t-6/2) = -2π(2.5t+3)/π = -5π/2(2.5t+3)
Therefore, the answer is -5π/2(2.5t+3).

Given the expression: sin^-1(sin(-5t-6))
To find the angle -z/2, we can use the following properties:
1. sin⁻¹ (sin(x)) = x, if -π/2 ≤ x ≤ π/2 (i.e., x is in the range of the principal branch of the inverse sine function).
2. The sine function has a periodicity of 2π. Therefore, sin(x) = sin(x + 2nπ), where n is an integer.

Given angle: -5t - 6
We need to add 2nπ to this angle to bring it into the range of -π/2 to π/2:
⇒ -5t - 6 + 2nπ, where n is an integer.

Now, we apply the sine and inverse sine functions:
sin⁻¹ (sin(-5t - 6 + 2nπ))

Since sin^-1(sin(x)) = x when x is in the range of the principal branch, our final expression becomes:
-z/2 = -5t - 6 + 2nπ

In this expression, -z/2 represents the angle in radians, written as a multiple of r. To find the multiple, you simply have to solve for -z/2 in terms of r.
Therefore, the answer is: -z/2 = -5t - 6 + 2nπ.

1. The Daily Statesman newspaper costs $6. 00 per week. The newspaper currently has 700


subscribers. The newspaper wants to increase its revenue and estimates that it will lose 40


customers for every $0. 75 increase in price. What weekly subscription price will maximize the


newspaper's weekly income? Round the answer to the nearest hundredth.

Answers

The newspaper should increase its subscription price by $2.19 to maximize its weekly income and the new subscription price would be  $8.19 per week.

To maximize the newspaper's income, we need to find the price that will result in the highest revenue. Let's assume that the newspaper increases the subscription price by x dollars.

Then the revenue R(x) can be expressed as:
R(x) = (700 - 40x) * (6 + 0.75x)

Expanding the expression, we get:

R(x) = 4200 + 1050x - 240x^2

To find the price that maximizes revenue, we need to find the value of x that maximizes R(x). We can do this by taking the derivative of R(x) with respect to x and setting it equal to 0:

dR/dx = 1050 - 480x = 0

Solving for x,

x = 1050/480 = 2.1875

Therefore, the newspaper should increase its subscription price by $2.19 to maximize its weekly income. The new subscription price would be:

6 + 2.19 = $8.19 per week.

Evaluate the definite integrals ∫(9x^2 - 4x - 1)dx =

Answers

Definite integral of ∫(9x^2 - 4x - 1)dx from a to b is 3(b^3 - a^3) - 2(b^2 - a^2) - (b - a).

To evaluate the definite integral ∫(9x^2 - 4x - 1)dx, you need to first find the indefinite integral (also known as the antiderivative) of the function 9x^2 - 4x - 1. The antiderivative is found by applying the power rule of integration to each term separately:
∫(9x^2)dx = 9∫(x^2)dx = 9(x^3)/3 = 3x^3
∫(-4x)dx = -4∫(x)dx = -4(x^2)/2 = -2x^2
∫(-1)dx = -∫(1)dx = -x
Now, sum these results to obtain the antiderivative:
F(x) = 3x^3 - 2x^2 - x
∫(9x^2 - 4x - 1)dx from a to b = F(b) - F(a)

To evaluate the definite integral ∫(9x^2 - 4x - 1)dx =, we need to use the formula for integrating polynomials. Specifically, we use the power rule of integration, which states that ∫x^n dx = (x^(n+1))/(n+1) + C, where C is the constant of integration.
Using this formula, we integrate each term in the given expression separately. Thus, we have:
∫(9x^2 - 4x - 1)dx = (9∫x^2 dx) - (4∫x dx) - ∫1 dx
                  = 9(x^3/3) - 4(x^2/2) - x + C
                  = 3x^3 - 2x^2 - x + C
Next, we need to evaluate this definite integral. A definite integral is an integral with limits of integration, which means we need to substitute the limits into the expression we just found and subtract the result at the lower limit from the result at the upper limit. Let's say our limits are a and b, with a being the lower limit and b being the upper limit. Then, we have:
∫(9x^2 - 4x - 1)dx from a to b = [3b^3 - 2b^2 - b] - [3a^3 - 2a^2 - a]
                                              = 3(b^3 - a^3) - 2(b^2 - a^2) - (b - a)
Therefore, the definite integral of ∫(9x^2 - 4x - 1)dx from a to b is 3(b^3 - a^3) - 2(b^2 - a^2) - (b - a).

A major corporation is building a 4,325 acre complex of homes, offices, stores, schools, and churches in the rural community of Glen Cove. As a result of this development, the planners have estimated that Glen Clove's population (in thousands) t years from now will be given by the following function.
P(t) = (45t^2 + 125t + 200)/t^2 + 6t + 40 (a) What is the current population (in number of people) of Glen Cove?
(b) What will be the population (in number of people) in the long run?

Answers

(a) To find the current population of Glen Cove, we need to substitute t = 0 in the given function.

P(0) = (45(0)^2 + 125(0) + 200)/(0)^2 + 6(0) + 40
P(0) = 200/40
P(0) = 5

Therefore, the current population of Glen Cove is 5,000 people (since the function is in thousands).

(b) To find the population in the long run, we need to take the limit of the function as t approaches infinity.

lim P(t) as t → ∞ = lim (45t^2 + 125t + 200)/(t^2 + 6t + 40) as t → ∞

Using L'Hopital's rule, we can find the limit of the numerator and denominator separately by taking the derivative of each.

lim P(t) as t → ∞ = lim (90t + 125)/(2t + 6) as t → ∞

Now, we can just plug in infinity for t to get the population in the long run.

lim P(t) as t → ∞ = (90∞ + 125)/(2∞ + 6)
lim P(t) as t → ∞ = ∞/∞ (since the numerator and denominator both go to infinity)

We can use L'Hopital's rule again to find the limit.

lim P(t) as t → ∞ = lim 90/2 as t → ∞
lim P(t) as t → ∞ = 45

Therefore, the population in the long run will be 45,000 people (since the function is in thousands).

How do you find square roots??

Step-by-step explanation:

Finding the square root of a number is simply jist dividing the given number by 2 till you get to the last number which should be 1 then you pair up the number of two's and multiply. For example you have 6 two's when you pair them in two's you get 3 two's left then you multiply the remaining two's which would then be 2×2×2 which is 6

Answer:

Step-by-step explanation:

so basically, a square root is just the number that is multipled together to equal that, so sq rt of 64 is 8. This is because 8x8= 64. If you were to take a weird number like sq rt of 112, it would be a little bit more difficult, however its pretty easy to do this through thinking of your multiplication charts. if you think about it 11x10 but thats 110, it would have to be a number around there. 11x11 is too high but 10x10 is too low. SO it would have to be a number around there. if you did 10.5x10.5 it would give 110.25. so if you try to do 10.6x10.6 it would equal 112.36. (The actual answer is 10.58300524425836)  So that is how you determine how close you can get. It is very tedious to do this process and very time consuming.

Cassie wants to buy a shirt for $15. 75 and some shoes for $10. 25. If the sales tax is 8. 25%, what is the TOTAL amount Cassie will pay?

Answers

The sales tax is 8.25% of the total cost of the shirt and shoes, so we need to add this to the cost of the items:

Cost of shirt = $15.75

Cost of shoes = $10.25

Total cost before tax = $15.75 + $10.25 = $26.00

Sales tax = 8.25% of $26.00 = 0.0825 x $26.00 = $2.15

Therefore, the TOTAL amount Cassie will pay is:

Total cost after tax = $26.00 + $2.15 = $28.15

The ratio of boys to girls in mrs. Cunninghams class is 2 to 3, there are 18 girls in the class. What is the total number of students in mrs. Cunninghams class

Answers

The total number of students in Mrs. Cunningham's class is 30.

From the question we know that the ratio of boys to girls in Mrs. Cunningham's class is 2 to 3 so we can write

no.of boys: no.of girls = 2:3

The total number of girls in the class is given as 18 so with this we can find out the number of boys in the class that is :

no.of boys= (2/3)*no.of girls in class

now after substituting the values in the equation, we get

no. of boys = (2/3) * 18

no.of boys = 12.

So, now we know the number of boys in the class that is 12 and the number of girls in the class is 18.

We can calculate the total number of students in the class which is equal to

= no.of boys + no.of girls.

= 12+18

=30

Therefore, the total number of students in Mrs. Cunningham's class is 30.

A hardware store carries 42 types of boxed nails and 36 types of boxed screws. the store manager wants to build a rack so that he can display the hardware in rows. he wants to put the same number of boxes in each row, but he wants no row to contain both nails and screws. what is the greatest number of boxes that he can display in one row? how many rows will there be if the manager puts the greatest number of boxes in each row?

Answers

There will be a total of 7 rows for nails and 6 rows for screws, making 13 rows in total.

To solve it, we need to find the greatest common divisor (GCD) of the number of boxed nails (42) and boxed screws (36). This will tell us the greatest number of boxes that can be displayed in one row without mixing nails and screws.

Step 1: List the factors of each number.
- Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
- Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

Step 2: Find the greatest common divisor (GCD) by identifying the largest factor they have in common.
- The largest common factor is 6.

So, the greatest number of boxes that can be displayed in one row is 6.

Next, we'll find out how many rows will there be if the manager puts the greatest number of boxes in each row.

Step 3: Divide the total number of boxed nails and boxed screws by the GCD.
- Rows for nails: 42 ÷ 6 = 7
- Rows for screws: 36 ÷ 6 = 6

Therefore, there will be a total of 7 rows for nails and 6 rows for screws, making 13 rows in total.

To determine the probabilities, we need to analyze each event separately and then use the multiplication rule of probability to find the probability of both events happening together.

The probability of getting a 3 on the coin is 50%, since there are only two possible outcomes. The probability of rolling each number on the cube is 16.67%, since the cube has six sides.

Answers

The area of the largest outside circle in square centimeters is closest to e)1,017.36 cm².

The area of the largest circle is equal to the sum of the areas of the three inner circles and the area of the white region between them. Since the three inner circles are congruent, we can divide the white region into three equal parts. Let the radius of each inner circle be 'r'. Then, the radius of the largest circle is '3r'.

The area of the white region is the difference between the area of the square and the sum of the areas of the three congruent sectors. The area of each sector is (1/6)πr².

Therefore, the area of the white region is (9/4) r². Finally, we can use the formula for the area of a circle to find the area of the largest circle: A = π(3r)² + 3(1/6)πr² - (9/4) r² = (63/4)πr². If we substitute the value of r as 6 cm (since the diameter of the inner circle is 12 cm), we get the area of the largest circle as (63/4)π(6)² ≈ 1,017.36 cm²(e).

What type of model does the data suggest?

y: 2. 5,5,10,20,40



either constant, exponential or linear

Answers

The data suggests that the model is exponential.

When we look at the values of y, we see that they are increasing at a much faster rate as x increases. For example, when x increases from 1 to 2, y doubles from 5 to 10, and when x increases from 3 to 4, y doubles from 20 to 40. This is a characteristic of exponential growth where the rate of increase gets larger and larger as the quantity being measured gets larger.

We can also see this by looking at the ratio of consecutive terms in the y values. For example, the ratio of y(1) to y(0) is 5/2.5 = 2, and the ratio of y(2) to y(1) is 10/5 = 2, indicating a constant ratio. This is a characteristic of exponential functions where the ratio between consecutive terms is constant.

Therefore, based on the rapid growth rate and the constant ratio of consecutive terms, we can conclude that the model for this data is exponential.

Answers

The density of the copper used in the pyramid is 8.4 g/cm³.

To find the density of the copper used in the pyramid, we first need to determine the volume of the cuboid and pyramid, and then find the mass of the copper.

1. Find the volume of the cuboid (V_cuboid):

V_cuboid = length × width × height

Since the base is a square, the length and width are both 3 cm.

V_cuboid = 3 cm × 3 cm × 8 cm = 72 cm³

2. Find the volume of the pyramid (V_pyramid):

First, find the height of the pyramid: total height (15 cm) - height of the cuboid (8 cm) = 7 cm.

V_pyramid = (1/3) × area of base × perpendicular height

The area of the base is 3 cm × 3 cm = 9 cm².

V_pyramid = (1/3) × 9 cm² × 7 cm = 21 cm³

3. Find the mass of the iron cuboid (m_iron):

Density of iron = 7.8 g/cm³

m_iron = density × V_cuboid = 7.8 g/cm³ × 72 cm³ = 561.6 g

4. Find the mass of the copper pyramid (m_copper):

Total mass of sculpture = 738 g

m_copper = total mass - m_iron = 738 g - 561.6 g = 176.4 g

5. Calculate the density of the copper (density_copper):

density_copper = m_copper / V_pyramid

A circular piece of board contains sections numbered 2, 9, 4, 9, 6, 9, 9, 9. If a spinner is attached to the center of the board and spun 10 times, find the probability of spinning fewer than four nines.

Answers

The probability of spinning fewer than four nines is 1,626,101,367 / 1073741824, which simplifies to approximately 1.514%.

To find the probability of spinning fewer than four nines, we need to first calculate the total number of possible outcomes. The spinner can land on any of the eight sections on the board, and it is spun 10 times. So, the total number of possible outcomes is 8^10, which is 1073741824.

Next, we need to calculate the number of outcomes where fewer than four nines are spun. We can do this by finding the number of outcomes with 0, 1, 2, or 3 nines, and adding them up.

To find the number of outcomes with 0 nines, we need to find the number of ways to choose from the non-nine sections on the board. There are 5 non-nine sections, and we need to choose 10 of them. This is a combination problem, and the number of outcomes is 252.

To find the number of outcomes with 1, 2, or 3 nines, we need to use a similar approach. We can use combinations to find the number of ways to choose the nines and the non-nines, and then multiply them together. The number of outcomes with 1 nine is 9 x 5^9, with 2 nines is 9 x 9 x 5^8, and with 3 nines is 9 x 9 x 9 x 5^7.

Adding up all these outcomes, we get 252 + 9 x 5^9 + 9 x 9 x 5^8 + 9 x 9 x 9 x 5^7 = 1,626,101,367.

So, the probability of spinning fewer than four nines is 1,626,101,367 / 1073741824, which simplifies to approximately 1.514%.

A park maintenance person stands 16 m from a circular monument. Assume that her lines of sight form tangents to the monument and make an angle of 56°. What is the measure of the arc of the monument that her lines of sight intersect?

Answers

The measure of the angle of the near arc of the monument that her lines of sight intersect with is 124°

What is the angle of an arc of a circle?

The angle of an arc of a circle is the angle formed by the two radii of the circle that intersects with the boundaries of the arc

The distance the park maintenance person stands from the monument = 16 m

The angle the lines of sight from the maintenance person that are tangent with the monument make where they intersect = 56°

Whereby the tangent lines from the monument to the maintenance person intersect and form an angle of 56°, we get that the tangent lines form two right triangles, please see the attached figure which is created with MS Excel;

The right triangles ΔABO and ΔACO are congruent by Leg Hypotenuse, LH, congruence rule

Therefore; ∠OAC ≅ ∠OBC

m∠OAC = m∠OBC (Definition of congruent angles)

Similarly, m∠BOA = m∠COA

However, m∠BAC = m∠OAC  + m∠OBC (Angle addition postulate)

m∠BAC = 2 × m∠OAC = 56°

m∠OAC = 56° ÷ 2 = 28°

m∠BOA = 90° - m∠OBC (Acute angles of a right triangle)

m∠BOA = 90° - 28° = 62°

Therefore, m∠BOA = m∠COA = 62°

The angle at the center = m∠BOC = m∠BOA + m∠COA

m∠BOC = 62° + 62° = 124°

Angle formed at the center of the monument, m∠BOC = 124°

The arc angle of a circle = The angle the radius of the arc forms at the center of the circle.

The measure of the arc close to the park maintenance person is 124°

Answers

Answer:

(-2,-8)

Step-by-step explanation:

First, we have to make these linear equations into standard form:

-3x+y=-2

and

9x-y=-10

Now we tell my using elimination method, we can cross out the y variables because when added(y+(-y)) is just 0, so we just cross them out

Add liked terms

6x=-12

Solve for X:

X=-2

Plug 2 for X in any equation (lets do -3x+y=-2)

Plug in -2 for X:

-3(-2)+y=-2

Thus we get 6+y=-2

Solve for Y:

y=-8

Now that we have both our variables, we know that the answer is (-2,-8)

Let f: R+R be a function that satisfies O 0. (a) Show that the series cosh(f(n)) ne1 diverges regardless of the rule for f. (b) Show that the series ( f(n) 2n3 - 1 converges regardless"

Answers

As we have proved that the series cosh(f(n)) ne1 diverges regardless of the rule for f, and that the series f(n) 2n³ - 1 converges regardless of the rule for f.

The comparison test states that if the terms of a series can be bounded below by a divergent series, then the given series also diverges.

In this case, we can bound the terms of cosh(f(n)) below by the series eⁿ. To see why, note that cosh(x) >= 1 for all x > 0. Thus, we have cosh(f(n)) >= 1 for all n. On the other hand, we know that e^x > 1 for all x > 0. Therefore, we have eⁿ > 1 for all n.

Since eⁿ diverges by the assumption that f satisfies O<f(), the comparison test tells us that cosh(f(n)) ne1 also diverges. Thus, the series cosh(f(n)) ne1 diverges regardless of the rule for f.

Moving on to the second part of the question, we are asked to show that the series ( f(n) 2n3 - 1 converges regardless of the rule for f. Again, we can use the comparison test to show convergence.

We can bound the terms of the given series by the series 1/n². To see why, note that for all n > 1, we have f(n) > 0 since the domain of f is restricted to R+. Thus, we have f(n)² < f(n) 2n³ - 1. Dividing both sides by n⁶, we get f(n)²/n⁶ < ( f(n) 2n³ - 1)/n⁶.

Now, note that the series 1/n² converges by the p-test (which states that the series 1/nᵃ converges if p > 1).

Therefore, by the comparison test, the series ( f(n) 2n³ - 1 also converges regardless of the rule for f.

Which trigonometric function is equivalent to sec(-270) ?

Answers

The trigonometric function equivalent to sec(-270) is -1.

The secant function is defined as the reciprocal of the cosine function, i.e., sec(x) = 1/cos(x). To find the value of sec(-270), we need to first find the cosine of -270 degrees. The cosine function has a period of 360 degrees, which means that cos(-270) is the same as cos(-270 + 360) = cos(90) = 0. Therefore, we have sec(-270) = 1/0, which is undefined.

However, we can determine the sign of sec(-270) by examining the quadrant in which the angle -270 degrees lies. Since -270 degrees is in the fourth quadrant, the cosine function is negative in that quadrant. Therefore, we can write sec(-270) = -1/0-, which is equivalent to -1. Hence, the trigonometric function equivalent to sec(-270) is -1.

Find the surface area of revolution about the x-axis of y = 4x + 2 over the interval 2

Answers

The surface area of revolution about the x-axis of y=4x+2 over the interval 2 is approximately 88.99 square units.

How to find the surface area of revolution

To find the surface area of revolution about the x-axis of y=4x+2 over the interval 2, we first need to express the equation in terms of x.

Rearranging the equation, we get x = (y-2)/4.

Next, we need to determine the limits of integration.

Since we are rotating about the x-axis, the limits of integration are the x-values, which in this case are 0 and 2.

Using the formula for the surface area of revolution, S = 2π∫(y√(1+(dy/dx)^2))dx, we can plug in the values we have found.

dy/dx for y=4x+2 is simply 4, so we get:

S = 2π∫(4x+2)√(1+16)dx from 0 to 2

Simplifying this, we get:

S = 2π∫(4x+2)√17 dx from 0 to 2

Evaluating this integral using calculus, we get:

S = 32π√17/3
