Answer:
the ball is in the air for 8 seconds
Step-by-step explanation:
f(x) = y
when y = 0, the ball would've travelled through the air over the final time of flight.
0 = -5x^2 + 40x + 0
use quadratic equation to find the value of x
x = (-b ± √b^2 - 4 • a • c) / 2 • a
x = (-40 ± √40^2 - 4 • -5 • 0) / 2 • -5
x = (-40 ± √1600) / - 10
x = (-40 ± 40) / - 10
x = 0 or x = 8
<u>Given </u><u>:</u><u>-</u>
- Length :- 8m
- Width :- 10
- Height :- 10m

formula for Surface Area = 2(LW + WH + HL)
- putting the known values,
Surface Area = 2(8×10 + 10×10 + 10×8) m²
<u>Surface</u><u> Area</u><u> </u><u>=</u><u> </u><u>2</u><u>(</u><u>2</u><u>6</u><u>0</u><u>)</u><u> </u><u>m²</u>
<u>Surface</u><u> Area</u><u> </u><u>=</u><u> </u><u>5</u><u>2</u><u>0</u><u>m</u><u>²</u><u> </u><u>(</u><u> </u><u>Option</u><u> </u><u>C</u><u>)</u>
