Answer:
The length of the diagonal of the frame equal 17 inches
Step-by-step explanation:
The diagonal dividing the rectangle as made the rectangle 2 triangles
So according to Pythagoras Theorem,
Hypothenus² = opposite² + adjacent²
The diagonal lent is the Hypothenus.
so the two other sides are taking as opposite and adjacent respectively
so taking h as hypothenus,
h² = 15² + 8²
h² = 225 + 64
h² = 289
h = √289
h = 17
Step-by-step explanation:
-4^(-5)/ 2^(-3) =
2³/(-4)^5 =
8/(-1024) =
- 1/128 (d)
Option c is correct. Use special right triangles and you will findout why. Hint:Use the 45-45-90 special right triangle's properties.
Answer:
After 2 seconds
Step-by-step explanation:
First step is find an equation of velocity:
h(t)=-16t2+64t+112. The velocity function is derivated from position function, so we should do that.
v(t)= h´(t)= -16*2*t+64 ⇒ v(t)= -32t+64.
Now we know the arrow reach the maximun height when this velocity is equal to zero when t>0.
0=-32t+64 ⇒ 32t=64, split each member for 32 ⇒
=
t=2. That means after 2 sec. the arrow reach the maximum height
