On series of transformation:

1. The series of transformations that maps ΔABC onto ΔDEF is a D, reflection followed by a dilation with a scale factor of 1.5, over the y-axis.

2. To find the length of the second rectangle, the two rectangles are similar, which means that their corresponding sides are proportional. Let's use x to represent the length of the second rectangle. Then:

5/2 = x/8

To solve for x, cross-multiply and simplify:

2x = 40/5

2x = 8

x = 4

Therefore, the length of the second rectangle is 4 feet.

3. Let w be the width of the rectangle. The perimeter is given by:

2(5) + 2w = 16

Simplifying:

2w = 6

w = 3

The length of the rectangle can be found using the ratio of corresponding sides:

5/3 = 10/l

Solving for l:

l = 6

According to the information we can infer that the parallel line would be AD or CF. Additionally, the perpendicular lines would be CB or FE.

To identify the parallel lines we must look at the figure and find the lines that have the same direction as the line BE and that would never intersect with the segment BE, according to the above, we can infer that the parallel lines would be:

On the other hand, the lines perpendicular to CF would be CB or FE because they make 90° angles with segment CF. Additionally, the face that would be parallel to ABC is DEF.

Answer: g(x)-f(x)=-x³-3x-3

Step-by-step explanation:

Since we are given g(x) and f(x), we can directly subtract them to find g(x)-f(x).

x-3-(x³+4x)           [distribute -1]

x-3-x³-4x              [combine like terms]

-3-x³-3x                 [rewrite]

-x³-3x-3

Now, we know that g(x)-f(x)=-x³-3x-3.

Answer:

\(\displaystyle \int_{0}^{5}\int_{0}^{-3x+15}f(x,y) \ dy dx\)

========================================================

Explanation:

We're tasked to find the values of a,b,c,d in the following

\(\displaystyle \int_{a}^{b}\int_{c}^{d}f(x,y) \ dy dx\)

The equation of the line through the points (0,15) and (5,0) is y = -3x+15

When picking a particular fixed x value, the y values span from y = 0 to y = -3x+15 which determines the bounds of integration for the inner integral.

So this means c = 0 and d = -3x+15

The values of a,b are much easier and they are a = 0 and b = 5 to represent the x coordinates of the left-most and right-most points.

-----------------

Since,

we go from this

\(\displaystyle \int_{a}^{b}\int_{c}^{d}f(x,y) \ dy dx\)

to this

\(\displaystyle \int_{0}^{5}\int_{0}^{-3x+15}f(x,y) \ dy dx\)

Without knowing what f(x,y) is, we cannot compute the integral. Luckily it seems like your teacher is only interested in setting up the integral rather than computing its numeric value.

Probability that exactly 10 flights arrive on time is 53.33%.

Given that,

The rates of on-time flights for commercial jets are continuously tracked by the U.S. Department of Transportation.

Recently, Southwest Air had the best rate with 80% of its flights arriving on time.

Total number flights in sample = 15

Probability that exactly 10 flights arrive on time is,

P = 10/15 × 80%

The male in the 92nd percentile in height would be 73.75 inches tall.

To find the z-score corresponding to the 92nd percentile, we need to find the value on the standard normal curve such that 92% of the area is to the left of that value.

Using the standard normal table, we can find the z-score closest to 0.92 which is 1.75.

Now that we have the z-score, we can use the following formula to find the height:

height = z-score * standard deviation + average height

So, using the given values of average height (70.5") and standard deviation (2.5"):

height = 1.75 * 2.5 + 70.5

height = 73.75"

Therefore, a male in the 92nd percentile in height would be 73.75 inches tall.

Answer:

C: maximum height=62.25 feet; time=3.85 seconds

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

\(f(x) = ax^{2} + bx + c\)

It's vertex is the point \((x_{v}, y_{v})\)

In which

\(x_{v} = -\frac{b}{2a}\)

\(y_{v} = -\frac{\Delta}{4a}\)

Where

\(\Delta = b^2-4ac\)

If a<0, the vertex is a maximum point, that is, the maximum value happens at \(x_{v}\), and it's value is \(y_{v}\).

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

\(ax^{2} + bx + c, a\neq0\).

This polynomial has roots \(x_{1}, x_{2}\) such that \(ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})\), given by the following formulas:

\(x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}\)

\(x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}\)

\(\Delta = b^{2} - 4ac\)

In this question:

The height of the ball, after t seconds, is given by the following equation:

\(h(t) = -16t^2 + 60t + 6\)

Which is a quadratic equation with \(a = -16, b = 60, c = 6\)

Maximum height:

Since a < 0, we can find the maximum value of the function. We have that:

\(\Delta = 60^{2} - 4(-16)(6) = 3984\)

\(y_{v} = -\frac{3984}{4(-16)} = 62.25\)

The maximum height is of 62.25 feet.

Seconds to reach the ground:

\(x_{1} = \frac{-60 + \sqrt{3984}}{2*(-16)} = -0.1\)

\(x_{2} = \frac{-60 - \sqrt{3984}}{2*(-16)} = 3.85\)

Since time is a positive measure, 3.85 seconds.

The correct answer is given by option C.
