Answer:
6.453 × 10 × -10 × -10 × -10
Step-by-step explanation:
6.453 × 10–^3
6.453 × 10 × -10 × -10 × -10
Is that a negative? The one after the 10? If not then just take away the negatives from the 10's.
Hope this helped!

Answer:
<em>after 4seconds</em>
Step-by-step explanation:
Given the height, h , in feet, of the football above the ground after t seconds expressed by h ( t ) = − 8 t^2 + 32 t, the height of the ball on the ground is 0feet.
Substitute h(t) = 0 into the expression and calculate t;
h ( t ) = − 8 t^2 + 32 t
0 = − 8 t^2 + 32 t
8t² = 32t
8t = 32
Divide both sides by 8
8t/8 = 32/8
<em>t = 4s</em>
<em>Hence the football hits the ground after 4seconds</em>

Answer:
x =2
Step-by-step explanation:
for this problem your solving for x so to do that you have to get it alone
so subtract 15 by both sides --> 3 -15 = -6x +15-15
getting --> -12 = -6x
now divide by -6 by both sides getting x = 2
