Answer:

8.11

Step-by-step explanation:

You round it up because the 3rd number (thousandths) is 5 or above, and since it's 7 you round that up and drop off the last number.

A water balloon is catapulted into the air so that it's height, in meters, after t seconds is h = -4.9t^ +27t +2.4

zysi [14]

$h = -4..9t^2+27t+2.4\ for\ t=3$

Just replace t with 3 and solve.

$h = -4.9*3^2 + 27*3 + 2.4 \\ h = -4.9*9 + 27*3 + 2.4 \\ h=-44.1 + 81 + 2.4 \\ \boxed{h=39.3}$

15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
35 ≠ 14
