Answer:
The diver will take 2.449 seconds to enter the water.
Step-by-step explanation:
We have been given that quadratic equation for the diver jumps is

We have to find the time taken for the diver to enter the water. When the diver enters the water, the height becomes zero.

Therefore, the diver will take 2.449 seconds to enter the water.
-- The area of the entire yard, before the garden was planted, was
(side)² = (20x)² = 400 x² .
-- The area of the circle where garden was put in is
pi R² = (pi) · (4x)² = 16 pi x² .
-- The remaining area of the yard ... the part not covered by
the circular garden ... is
(400x²) - (16pi x²) = x² (400 - 16pi)
= 349.7 x² square units.
Answer:
try putting -5x I believe that's it
Try The 3rd one I know it’s right
Average rate of change over [1,5] = f(5) - f(1) / 5 - 1
= [(17-5^2) - (17-1) ] / 4
= (-8 - 16) / 4 = -24 / 4 = -6 Answer
