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

Answer:
c
Step-by-step explanation:
Hey!~
The simplified version of this equation in slope-intercept form would be y=3x-1.
"M" is commonly used for the slope.
"B" is used for the x-intercept.
In this equation, 3 is the slope (m), and -1 is the x-intercept (b).
Hope this helps and have a great day!

Answer: 80 dollars
Step-by-step explanation:
You can find a percentage with one of two ways.
For hundreds like this, oftentimes it's quicker and more simple to think of it as just 100. The proportion from 100 to 500 is just 5. 16% of 100 is 16. So, multiply 16 * 5. You would get 80.
The second method is you can use 0.16 * 500. It's the more conventional method, and you get 80, like the last method.
