A cliff diver leaps from a 100-foot cliff into the Pacific. The diver's height above the water is modeled by the function
P(x) = -16x2 + 10x + 100, where x is time in seconds.
During which interval is the diver at least halfway down?
A.2.0 B.2.1 C.3.0 D.3.4

2.1

Step-by-step explanation:

Use F ookin desmos

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
