Answer:

If the units in the equation are in feet, it lef5t at a height of 7.4 feet (or meters, etc.).

Step-by-step explanation:

p(x) = - 0.013x2 + 0.02x + 7.4

When x, the time, = 0 [just before it leaves the pitcher's hand]

p(0) = 7.4

The points (4, 5), (−1, 7), (−2,−2), and (6.5,−10.5) reflected in the x-axis followed by the y-axis are (−4,−5), (1,−7), (2, 2),

Reflecting the points in the y-axis followed by the x-axis gives the same result as x-axis followed by the y-axis

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> rotation, reflection, translation and dilation.</em>

If a point A(x, y) is reflected along the x axis, the new point is A'(x, -y). If a point A(x, y) is reflected along the y axis, the new point is A'(-x, y).

Given the points (4, 5), (−1, 7), (−2,−2), and (6.5,−10.5). If it is reflected along the y axis it gives (-4, 5), (1, 7), (2,−2), and (-6.5,−10.5). If it is then reflected along the x axis it gives (-4, -5), (1, -7), (2, 2), and (-6.5, 10.5).

Reflecting the points in the y-axis followed by the x-axis gives the same result as x-axis followed by the y-axis

Can somebody help mee plzzzzzzzz
hammer [34]

Answer:

lines a and b are parallel. The slopes are -1/3

None of the lines are perpendicular to each other.

Step-by-step explanation:

To figure out if any of the lines are parallel or perpendicular to each other, you have to find the slopes of each line. To find the slope look at the graph find the rise over run for all of the lines:

line a: This line goes down one every time it goes over 3, which can be represented by -1/3

line b: This lines goes down one every time it goes over 3, which can also be written as -1/3

line c: This line goes up 5 every time it goes over 2, which makes the slope 5/2

When two lines are parallel, they have the same slope. Line a and line b have the same slope, so they are parallel.

When two lines are perpendicular, their slopes are negative reciprocals of each other. Since none of the slopes are a negative reciprocal of another slope, we have no perpendicular lines.

Hope this helps :)

A 90% confidence interval for the average weight (in pounds) of Americans was found to be (185, 210). The point estimate for thi
Lynna [10]

Answer:

B. 12.5

Step-by-step explanation:

We have the lowe confidence interval = 185

The upper confidence interval = 210

Mean of X = (lower confidence + upper confidence interval)/2

Mean of X = 185 + 210/2

= 197.5

The margin of error = the upper confidence interval - mean of X

= 210-197.5

= 12.5
