In a physics class demonstration, a ball is dropped from the roof of a building, 72 ft above the ground. The height, h, in feet,

of the ball above the ground is given by the function h = -16t2 + 72, where t is time in seconds.

The graph is shown below:

<h3>What is Graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

h(t) = -16t² + 72

For t=-1,

h(-1) = -16 * (-1)² +72

h(-1) = -16 +72= 56

Ordered pair is ( -1, 56)

For t=1,

h(1) = -16 * (1)² +72

h(1) = -16 +72= 56

Ordered pair is ( 1, 56 )

For t=2,

h(2) = -16 * (2)² +72

h(2) = -64 +72=  8

Ordered pair is ( 2, 8 )

For t=3,

h(2) = -16 * (3)² +72

h(2) = -144 +72=  -72

Ordered pair is ( 3, -72)

Part A: If (2^6)^x = 1, what is the value of x? Explain your answer. (5 points)
vladimir1956 [14]

Answer:

0,1,-1

Step-by-step explanation:

A.

(2^6)^x=1\\(2)^{6x}=1=2^0\\6x=0\\x=\frac{0}{6}=0

B

(5^0)^x=1\\5^0=1\\1^x=1\\x=0,1,-1\\1^0=1\\1^1=1\\1^{-1}=\frac{1}{1^1}=\frac{1}{1}=1

Answer:

y = -3x - 3

Step-by-step explanation:

First, determine the slope of the red line.  As we move from (0, 3) to (1, 0),

x increases by 1 and y decreases by 3.  Hence, the slope, m, is

m = rise / run = -3 / 1, or m = -3.

The desired new line, parallel to the red line, has the same slope as the red line:  m = -3.

The equation for this new line is y - k = m (x - h), where (h, k):  (-1, 0):

We get y - 0 = -3 (x + 1), or y = -3x - 3.

Check:  Does this line go thru the given point (-1, 0)?

Is 0 = -3(-1) - 3 true?  Yes, it is true.

Sandy had test scores of 20, 25, 17, 22, and 21. What is the average (mean) score. On the next 3 test Sandy's score were 24, 24,
Nata [24]

Answer:

a) First Average mean = 21

b) Current mean = 22

Step-by-step explanation:

Formula For mean =

Sum of Terms/ Number of terms

a)Sandy had test scores of 20, 25, 17, 22, and 21.

Number of terms = 5

Mean = (20 + 25 + 17 + 22 + 21)/5

= 105/5

= 21

b) On the next 3 test Sandy's score were 24, 24, and 23

To calculate this current mean, we will add the first 5 test scores, with this current 3 test scores and then find the average.

Mean = (20+ 25+ 17 +22 +21 + 24 + 24 + 23)/8

Mean = 176/8

Mean = 22
