Answer:

y = 0.5 cosine (4 (x - pi/2)) - 2

Step-by-step explanation:

Taking the general form:

y = A cosine (Bx - Cπ)) + D

In the following case. the constants are:

y = 0.5 cosine (4x - 2π)) - 2

A: 0.5

B: 4

C: 2π

D: -2

The range of this function is:

range = [-|A|+D, |A|+D]

range = [-0.5-2, 0.5-2]

range = [-2.5, -1.5]

Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"

At x = 0, the function value is:

y = 0.5 cosine (4(0) - 2π)) - 2

y = 0.5 - 2 = -1.5

As indicated in "a curve crosses the y-axis at y = negative 1.5"

The period of the function is:

period: 2π/B

period = 2π/4 = π/2 or 2 cycles at π

as described in "It goes through 2 cycles at pi."

A ball is thrown into the air with an upward velocity of 48 ft/s. Its height h in feet after t seconds is given by the function
Masja [62]
The equation modeling the height of the ball at time,t is given by h=-16t²+48t+6
<span>a. In how many seconds does the ball reach its maximum height?
Time taken for the ball to reach the maximum height will be given by:
h'(t)=-32t+48=0
finding the value of t we get:
32t=48
t=48/32
t=1.5 seconds
Thus the time taken for the ball to reach the maximum time is 1.5 seconds

b]</span><span> What is the ball’s maximum height?
The maximum height will be:
h(1.5)=-16(1.5)</span>²+48(1.5)+6
h(1.5)=42 fee

Michael record the number of miles he runs each week for the nine weeks 6,11,13,8,15,9,11,5,9 which box plot represents the data
Nina [5.8K]
<h3>Answer: Upper right corner</h3>

Five number summary

  • min = 5
  • Q1 = 7
  • median = 9
  • Q3 = 12
  • max = 15

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

Explanation:

The given list of values is {6, 11, 13, 8, 15, 9, 11, 5, 9}

It sorts to {5, 6, 8, 9, 9, 11, 11, 13, 15}

The middle most value is the second 9. We have four items below or at the median {5,6,8,9} and four values above the median {11,11,13,15}

The middle item of {5,6,8,9} is (6+8)/2 = 14/2 = 7. This is the value of Q1.

The middle item of {11,11,13,15} is (11+13)/2 = 24/2 = 12. This is Q3.

The min is 5 since it is the smallest of the original list.

The max is 15 because it is the largest of the original list.

The five number summary is

  • min = 5
  • Q1 = 7
  • median = 9
  • Q3 = 12
  • max = 15

The boxplot that matches with this five number summary is the boxplot in the upper right corner.

The min is the left whisker. The max is the right whisker.

The left edge of the box is Q1. The right edge of the box is Q3.

The middle vertical line inside the box is the median.
