An image of a coordinate plane shows a dashed horizontal line. The line crosses the y-axis at (0, 2) and passes through the points (2, 2) and (negative 2, 2). The area above the line is shaded.

Answers

Answer 1

Answer:

To determine if (0,3) is a solution to y>2, we need to check if y is greater than 2 when x=0 and y=3. Since 3 is greater than 2, the point (0,3) satisfies the inequality y>2.

To graph the inequality y>2, we need to shade the region above the horizontal line y=2. The line y=2 is a solid line since it includes the points where y=2, but the region above the line is shaded with a dashed line since it does not include the points where y=2.

Here is a description of the graph:

Draw a horizontal line passing through the point (0,2).

Shade the region above the line with a dashed line.

The graph visually represents all the points that satisfy the inequality y>2. Since the point (0,3) is above the line, it is part of the shaded region and satisfies the inequality.

If a ramp is 3m high and 10m long. what is the measure of angle formed by the ramp and ground​

Answers

Answer:

16.7 degrees

Step-by-step explanation:

We can use the tangent ratio of a right triangle to solve this problem.

The tangent of an angle is the ratio of the opposite side to the adjacent side. In this case, the opposite side is the height of the ramp (3m) and the adjacent side is the length of the ramp (10m).

So we have:

tan(theta) = opposite / adjacent

tan(theta) = 3 / 10

To find the angle, we need to take the inverse tangent (or arctangent) of both sides:

theta = arctan(3 / 10)

Using a calculator, we get:

theta ≈ 16.7 degrees

Therefore, the angle formed by the ramp and ground is approximately 16.7 degrees.

You plan to borrow $3825 at 15% annual interest for 4 years. What will your monthly
payment be? Use the formula . Make sure to label each variable. must show work

Answers

We can use the formula for the monthly payment of a loan to calculate the amount we need to pay each month:

M = (P * r * (1+r)^n) / ((1+r)^n - 1)

Where:

M = the monthly payment

P = the principal (the amount borrowed)

r = the monthly interest rate (which is the annual interest rate divided by 12)

n = the total number of months in the loan term (which is the number of years multiplied by 12)

Plugging in the given values, we get:

P = $3825

r = 15% / 12 = 0.0125

n = 4 years * 12 = 48 months

M = ($3825 * 0.0125 * (1+0.0125)^48) / ((1+0.0125)^48 - 1)

M ≈ $94.87

Therefore, the monthly payment will be approximately $94.87.

$94.87 will be the interest needed

Find
1-The mid point
2-The slop
3-The length
4 - The equation

Answers

Answer:

1, the mid point

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) can be found using the midpoint formula:

midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Substituting the given endpoints (4, -4) and (0, 9), we get:

midpoint = ((4 + 0) / 2, (-4 + 9) / 2) = (2, 2.5)

Therefore, the midpoint of the line segment with endpoints (4, -4) and (0, 9) is (2, 2.5).

2,  the slope

The slope of the line passing through the points (4, -4) and (0, 9) can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Substituting the given coordinates, we get:

slope = (9 - (-4)) / (0 - 4) = 13 / (-4) = -3.25

Therefore, the slope of the line is -3.25.

3, the length

The length of the line passing through the points (4, -4) and (0, 9) can be found using the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Substituting the given coordinates, we get:

distance = sqrt((0 - 4)^2 + (9 - (-4))^2) = sqrt(16 + 169) = sqrt(185)

Therefore, the length of the line is sqrt(185).

4,  the equation

The equation of the line passing through the points (4, -4) and (0, 9) can be found using the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is one of the points.

Substituting the given slope and one of the points, we get:

y - (-4) = -3.25(x - 4)

Simplifying, we get:

y + 4 = -3.25x + 13

y = -3.25x + 9

Therefore, the equation of the line passing through the points (4, -4) and (0, 9) is y = -3.25x + 9.

and goes through the
point (2,-18). Write the function in factored form. Remember to find the leading coefficient "a".

“mul” is multiplicity

Answers

Answer:

the final factored form of the function is:

f(x) = 6(x+1)^2(x-3)(x-1)

Step-by-step explanation:

To write the function in factored form, we need to use the zeros and their multiplicities.

From the given zeros, we can write:

x = -1 (multiplicity 2) means (x+1)(x+1) = (x+1)^2 = 0

x = 3 (multiplicity 1) means (x-3) = 0

x = 1 (multiplicity 1) means (x-1) = 0

So the factored form of the function is:

f(x) = a(x+1)^2(x-3)(x-1)

To find the value of "a" and satisfy the condition that the function goes through the point (2,-18), we can substitute the given point into the function:

-18 = a(2+1)^2(2-3)(2-1)

-18 = a(-3)

Solving for "a", we get:

a = 6

So the final factored form of the function is:

f(x) = 6(x+1)^2(x-3)(x-1)

The transformations are:

Which are the transformations applied to the parent sine function?

The general sine function is:

y = sin(x)

The first thing we can see, is that the amplitude is not 1 like in the parent sine function, in this case the amplitude goes from the top value to the midline, so it is:

A = 5 - 3 = 2

Then we can write:

y = 2*sin(x)

So this is a vertical dilation of scale factor 2

We also can see the midline is at y = 3 instead of at y  = 0, so we have a vertical shift of 3 units up to get.

y = 2sin(x) + 3

Finally, we can see that the function starts decreasing after x = 0, so we have a shift of 1  (the horizontal axis is in units of pi)

y = 2*sin(x + 1) + 3

That is the graphed function.

Answers

A)  64π inches² B) 94.15π inches² C) the pizza from Tallahassee is larger. D)  The scale factor relationship between the pizzas is:  1.462

Part A: The diameter of the pizza from Tallahassee is 16 inches, so the radius is 8 inches. The area of the pizza is:

A = πr²

= π(8)²

= 64π inches²

Part B: The diameter of the pizza from Jaco, Costa Rica is 27.8 centimeters. Converting this to inches, we get:

27.8 cm ÷ 2.54 cm/inch = 10.94 inches

The radius is 5.47 inches, so the area of the pizza is:

A = πr²

= π(5.47)²

= 94.15π inches²

Part C: Converting the area of the pizza from Tallahassee to square centimeters, we get:

64π inches² × (2.54 cm/inch)² = 1648.89 centimeters²

The area of the pizza from Jaco, Costa Rica is 94.15π inches² × (2.54 cm/inch)² = 594.85π centimeters². Therefore, the pizza from Tallahassee is larger.

Part D: The scale factor relationship between the pizzas is:

16 inches ÷ 27.8 cm × 2.54 cm/inch = 1.462

This means that the diameter of the pizza from Tallahassee is 1.462 times larger than the diameter of the pizza from Jaco, Costa Rica. Since area is proportional to the square of the diameter (or radius), the area of the pizza from Tallahassee is (1.462)² = 2.14 times larger than the area of the pizza from Jaco, Costa Rica.

the length of AC is 5. we can get the answer with the help of  Pythagorean theorem in triangle ABC.

what is Pythagorean theorem ?

The Pythagorean theorem is a fundamental concept in geometry that relates to the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).

In the given question,

In triangle ABC, we have:

angle ABC = 90 degrees (given)

AB = 4 (given)

AD = 3 (given)

Let's call the length of AC "x". We want to find the value of x.

From the given information, we know that BD is the altitude of triangle ABC from vertex B to the side AC. Therefore, the length of BD is equal to the length of AD, which is 3.

Using the Pythagorean theorem in triangle ABD, we can find the length of the hypotenuse AB:

AB² = AD² + BD²

AB² = 3² + 4²

AB² = 9 + 16

AB² = 25

AB = 5

Now, we can use the Pythagorean theorem in triangle ABC to find the length of AC:

AC² = AB² + BC²

AC² = 5² + BC²

But we don't know the length of BC. However, we can use the fact that triangle ABD and triangle ABC are similar. This is because angle ABD is a right angle (from the definition of altitude BD), and angle ABC is a right angle (given), so angle ABD and angle ABC are both right angles. Therefore, the two triangles share angle A and are similar by the AA (angle-angle) similarity criterion.

Since triangles ABD and ABC are similar, we have:

AB/AD = AC/BD

Substituting the known values, we get:

5/3 = x/3

Solving for x, we get:

x = 5

Therefore, the length of AC is 5.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Here, we have,

Since the rectangle has a length of 4 meters and a width of 9 meters we need to find the area of rectangle

Area of rectangle  = length × width

Area of rectangle = 4 m × 9 m

Area of rectangle = 36 m^2

Since the  triangle has a base of 6 meters (9 meters - 3 meters o) and a height of 3 meters we need to find the Area of triangle

Area of triangle  = (1/2) × base × height

Area of triangle  = (1/2) × 6 m × 3 m

Area of triangle  = 9 m^2

Now let find the total area of the composite figure

Total area = Area  of rectangle + Area of triangle

Total area = 36 m^2 + 9 m^2

For rectangle ABCD, the new coordinate of A' is (5,1) and the correct rule is (x, y) → (-x, y).

What exactly is a rectangle?

A rectangle is a four-sided flat shape (quadrilateral) where all four angles are right angles (90 degrees) and opposite sides are parallel and congruent (equal in length). In other words, a rectangle is a parallelogram with all right angles.

Now,

The rule that shows the input and output of reflecting a point over the y-axis is (x, y) → (-x, y). This means that the x-coordinate of the point is negated, while the y-coordinate stays the same.

To find the new coordinate of A', we need to reflect the original point A(-5,1) over the y-axis. Using the rule above, we get:

A' = (-(-5), 1) = (5, 1)

Therefore, the new coordinate of A' is (5,1) and the correct rule is (x, y) → (-x, y).

On an episode of Project Runway, the designers had to ask random people in Central Park to be their models. If the probability that one of these random people said “yes” to being a designer’s model is 0.38, what is the probability that a designer would have to ask at most 3 people to find someone that would agree to be their model?

0.1461

0.2383

0.3844

0.6156

0.7617

Answers

To solve this problem, we can use the geometric distribution, which models the number of trials needed to obtain the first success in a sequence of independent trials.

Let X be the random variable representing the number of people a designer needs to ask until they find someone who agrees to be their model. Then X follows a geometric distribution with probability of success p = 0.38.

How to calculate?

The probability that a designer needs to ask at most 3 people is the sum of the probabilities that they need to ask 1, 2, or 3 people:

P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3)

We can calculate these probabilities as follows:

P(X = 1) = p = 0.38

P(X = 2) = (1-p) × p = 0.62 × 0.38 = 0.2356

P(X = 3) = [tex](1-p)^{2}[/tex] × p = [tex](0.62)^{2}[/tex] × 0.38 = 0.1448

Therefore, the probability that a designer would have to ask at most 3 people to find someone that would agree to be their model is:

P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3) = 0.38 + 0.2356 + 0.1448 = 0.7604

Rounding this to four decimal places, we get 0.7604, which is closest to the answer option (D) 0.6156. However, none of the given answer options matches the calculated probability exactly.

Question 5(Multiple Choice Worth 2 points)
(Rotations MC)

Polygon PSRT is drawn with vertices at P(1, 5), S(1, 0), R(−2, −3), T(−4, 2). Determine the image vertices of P′ if the preimage is rotated 90° counterclockwise.

P′(1, 5)
P′(−1, −5)
P′(5, −1)
P′(−5, 1)

Answers

The image vertices of P' if the preimage is rotated 90° counter clockwise is P'(-5,1)

What is image vertices?

An image vertex refers to a point in the plane that results from applying a transformation to a given vertex. A transformation is a mathematical operation that changes the position, size, or shape of a figure.

According to question:

The image vertices of P' when the preimage polygon PSRT is rotated 90° counter clockwise can be found by applying a transformation to each vertex of the polygon. This transformation involves switching the x- and y-coordinates of each vertex and negating the new y-coordinate.

(x, y) -> (-y, x)

For the vertex P(1, 5), we can apply this transformation to get the image vertex P':

P' = (-5, 1)

Similarly, we can apply the transformation to the other vertices of the polygon:

S(1, 0) -> S'(0, 1)

R(−2, −3) -> R'(3, -2)

T(−4, 2) -> T'(2, 4)

Therefore, the image vertices of P' are P'(-5, 1), S'(0, 1), R'(3, -2), and T'(2, 4).

This means that the rotated polygon has the vertices P', S', R', and T', which form a new polygon that is 90° counter clockwise rotated from the original polygon PSRT.

Find the probability of getting 2 or 4 or 6 when a dice is rolled

Answers

Answer:

The probability of getting a 2, 4, or 6 when a dice is rolled is 1/2, or 50%. This is because there are six possible outcomes when a dice is rolled, and three of them are favorable outcomes (2, 4, or 6). Therefore, the probability of getting a 2, 4, or 6 is 3/6, which simplifies to 1/2 or 50%.

Boxes of cereal are labeled as containing 14 ounces. Following are the weights, in ounces, of a sample of 12 boxes. It is reasonable to assume that the population is approximately normal.
Construct a 99% confidence interval for the mean weight. Round the answers to at least three decimal places.
Refer to photo.

Answers

The 99% confidence interval for the mean weight is 12.61 < μ < 14.15 where μ is the sample mean.

What is confidence interval?

A confidence interval is used to represent a range of values that are likely to contain the true population parameter.

In this case, the population parameter we are interested in is the mean weight of boxes of cereal labeled as containing 14 ounces.

The 99% confidence interval for the mean weight can be calculated by first determining the sample mean and standard deviation. The sample mean is 13.38 ounces and the sample standard deviation is 0.33 ounces.

To calculate the 99% confidence interval, we use the t-distribution to find the t-critical value for a sample size of 12 and a confidence level of 99%. The t-critical value for a 99% confidence level is 2.76. The formula for the confidence interval is given by:

μ ± t*√(s/√n)

Where μ is the sample mean, t is the t-critical value, s is the sample standard deviation and n is the sample size.

Therefore, the 99% confidence interval for the mean weight is

13.38 ± 2.76*√(0.33/√12) = 13.38 ± 0.82.

Therefore, the 99% confidence interval for the mean weight is 12.61 < μ < 14.15.

By answering the presented question, we may conclude that Therefore, the future value of the ordinary annuity is $16,178.55 when interest is compounded annually.

what is interest ?

In mathematics, interest is the amount of money gained or payable on an original investment or loan. You can use either simple or compound interest. Simple interest is calculated as a percentage of the initial amount, whereas compound interest is calculated on the principal amount plus any previously earned interest. If you invest $100 at a 5% annual simple interest rate, you will get $5 in interest per year for three years, for a total of $15.
