Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 96t[/tex]
Required
Seconds to attain maximum height
The maximum of a quadratic function [tex]y = ax^2 + bx + c[/tex] is calculated using:
[tex]x = -\frac{b}{2a}[/tex]
So, we have:
[tex]t = -\frac{b}{2a}[/tex]
Where:
[tex]a = -16[/tex] and [tex]b = 96[/tex]
So:
[tex]t = -\frac{96}{2 * -16}[/tex]
[tex]t = -\frac{96}{-32}[/tex]
Cancel out negatives
[tex]t = \frac{96}{32}[/tex]
[tex]t = 3[/tex]
3. The number of patients at a doctors office is tracked over a period of 10 days. Which statement best
supports the data?
A. The data for Dr. Amine's office is more
symmetrical than the data for Dr. Harris's office.
B. The interquartile range of the two offices is the
same.
C. The median number of patients at Dr. Harris's
office is less than the median number of patients
at Dr. Amine's office
D. The range of the data for Dr. Harris's office is less
than the range of the data for Dr. Amine's office
Answer:
The data for Dr. Amine's office is more
symmetrical than the data for Dr. Harris's office.
Step-by-step explanation:
Using visual inspection, Dr. Amine's office data is symmetrical as the median value is well. Positioned in between the box plot with approximately the same width to both left and right of the plot from the median value. While that of Dr. Harris office is clearly skewed.
From the median value and range values, Dr. Harris's office has greater value than Dr. Amine's office, hence the options are false. The interquartile range are also not the same.

When Camden runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 1.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 68% of his finishing times in the 400 meter race.
Answer:
63.5, 66.5
Step-by-step explanation:
Approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.
What is the empirical rule?The empirical rule states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, approximately 95% of the data lies within two standard deviations of the mean, and approximately 99.7% of the data lies within three standard deviations of the mean.
Since we want to find the interval that represents the middle 68% of Camden's finishing times, we need to find the range of times that are one standard deviation above and below the mean.
The mean of Camden's finishing times is 65 seconds, and the standard deviation is 1.5 seconds, so the interval that represents the middle 68% of his finishing times is:
[65 - 1.5, 65 + 1.5] = [63.5, 66.5] seconds
This means that approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

Answer:
C
Step-by-step explanation:
First, find the slope:
Formula for slope:
m = y2 - y1 / x2 - x1
m = -2 - -5 / 0 - -1
m = - 2 + 5 / 0 + 1
m = 3 / 1
m = 3
Next, find the y-intercept:
When x = 0, y = ???
According to the chart, when x = 0, y = -2. This is our y-intercept, also known as b.
Format the answers:
y = 3x + -2
y = 3x - 2
Check your work:
Plug in any x value and the y value should match the chart:
-5 = 3(-1) - 2
-5 = -3 - 2
-5 = -5
Correct

=============================================================
Explanation:
A full circle is 360 degrees. The pie slices shown represent the various angles of each slice. Each angle expression in that diagram will add up to 360.
Doing this will help us solve for x.
(angleVQR)+(angleRQS)+(angleSQT)+(angleTQU)+(angleUQV) = 360
(21x+4) + (14x-4) + (5x+5) + (5x+5) + (80) = 360
45x+90 = 360
45x = 360-90 ... subtract 90 from both sides
45x = 270
x = 270/45 ..... divide both sides by 45
x = 6
We'll then plug this x value into the angle expression for angle TQU
angle TQU = 5x+5
angle TQU = 5*6+5
angle TQU = 35 degrees
----------
Extra info:
angle VQR = 130 degreesangle RQS = 80 degrees (same as angle UQV)angle SQT = 35 degrees (same as angle TQU)Starting at angle VQR, and working clockwise, the five angles are: 130, 80, 35, 35, 80. Note that 130+80+35+35+80 = 360.Which of the following is the product of the rational expressions shown here? X/(x+1)*(2/x-1)
Answer:
its B
2×x=2x

Penny solved an equation by subtracting 6 from each side of the equation and then dividing each side by 5.
Answer:
Step-by-step explanation:
In order to solve for x, she had to first subtract 6 on both sides of the equation. Then divide by 5 on both sides of he equation. After the division part, she was able to successfully isolate x.
The equation she had to solve was (C) 5x+6=21
First step: Subtracting 6 on both sides of equation resulted in
5x = 15
Second step: Dividing both sides of the equation by 5 resulted in
x = 3
