Answer:
<em>0.5seconds later</em>
Step-by-step explanation:
Given the height modeled by the equation:
s(t) = -16t^2 + 16t + 1152
The velocity of the object at the moon surface is zero
ds(t)/dt = 0
ds(t)/dt = -32t + 16
0 = -32t + 16
32 t = 16
t = 16/32
t = 1/2
t = 0.5seconds
<em>Hence the object strikes the moon surface 0.5seconds later</em>
Hello there!
(a + b)² = a² + 2ab + b²
= a² + b² + 2ab
= 16 + 2(8)
= 16 + 16
= 32
As always, it is my pleasure to help students like you!
Answer:
x=(-9)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(−2/3)(9+x)=0
(−2/3)(9)+(−2/3)(x)=0(Distribute)
−6+−2/3x=0
−2/3x−6=0
Step 2: Add 6 to both sides.
−2/3x−6+6=0+6
−2/3x=6
Step 3: Multiply both sides by 3/(-2).
(3−2)*(−2/3x)=(3−2)*(6)
x=−9
Answer:b
Step-by-step explanation:
-3 I think because 9x3= 27 so 9x-3= -27
