Answer:
A.
Step-by-step explanation:
correct answer is
if to compare the values of the y, (0;100), (1;91), (2;82.81), (3; 75.3571), then
75.3571/82.81=82.81/91=91/100=0.91, it means the next value is decreased at 9%.
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
The correct answer is D. Good luck! :)
