The expression of the height is

a_n=8\cdot (\frac{1}{2})^{n-1}

the index "n" is the numbers of times that the ball is down, to n=1 the height is 8 inches, to n=2 the height is 4 inches.

An when n=5, the height is

a_5=8\cdot (\frac{1}{2})^{5-1}=8\cdot (\frac{1}{2})^4=\frac{1}{2} =0.5

the anwers is 0.5 inches

Help me plz I beg you
scZoUnD [109]
The answer would be C. We know that d is equal to the initial depth of a lake. The two given initial depths are 58 feet and 53 feet, so we know that one of the equations must be either d=58 or d=53. Because there only C has either one of those, d=58, we know that it must be the answer.

To find the other equation, it is just a linear function for the other lake. The y-intercept, or initial value, is 53, so in the equation y=mx+b, it is the b value. The slope, or m value, is 3 feet, so you have y=d=3x+53.

Nuetrik [128]

Answer:

The answer is 600.

Step-by-step explanation:

This is because 5 percent of 800 is 40. 800+40 = 840. 15 percent of 800 is 160. 840 - 160 is 680. 10 percent of 800 is 80. 680 - 80 is 600.

If this is right an you mar me brainliest? Thank you and have a good day!
