Answer:
153.86
Step-by-step explanation:
formula - A = π × r2
3.14 x 7^2
= 153.86
Resposta: f ^ (- 1) (x) = (1/2) x-1/2
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
