Answer:
f(-4) = - 16
Step-by-step explanation:
f(-4) = (-4)2 + 8(-4)
f(-4) = 16 + -32
f(-4) = - 16
Answer: To find the volume, you multiply length times width times height:
6*8*8 = 384 cubic inches
Hope this helps!
D(t)=-16t²+32t+88
a] Maximum height
At maximum height d'(t)=0
from d(t);
d'(t)=-32t+32=0
thus
t=1
hence the maximum height will be:
d(t)=-16t²+32t+88
d(1)=-16(1)^2+32(1)+88
d(1)=104 ft
2] <span> how many seconds does it take to reach the ground after first being thrown upward?
Here we solve for t intercept
</span>when d(t)=0
<span>thus</span>
0=-16t²+32t+88
<span>solving for t, we get:
t=1-</span>√13/2
or
<span>t=1+</span>√13/2
<span>
t=-1.55 or t=3.55 sec
Thus the answer is t=3.55 sec

Answer
When markup is based on cost, markup is the rate percentage
Step-by-step explanation:
During the selling of merchandise or services to customers, the business person has to charge a price higher than the cost of goods or labor so as to get profit. The markup of cost is therefore the percentage of an item’s wholesale cost that the retailer adds in its retail price to make profits.
