747.7
d=14 we are looking for the radius divided it to half so it should be 7
the height is 10
A=2πrh+2πr2=2·π·7·10+2·π·72≈747.69905
Answer:
Step-by-step explanation:
<u>Given system:</u>
<u>Substitute x into the second equation:</u>
- 10(y + 4) + 2y = 16
- 10y + 40 + 2y = 16
- 12y = -24
- y = -2
<u>Find x:</u>

Reyna runs a textile company that manufactures T-shirts. The profit, p, made by the company is modeled by the function p
=
s^2+9s-142, where s is the number of T-shirts sold. How many T-shirts should be sold to earn a profit of more than $2,000?
Answer:
s>42
Reyna needs to sell more than 42 T-shirts.
Step-by-step explanation:
Given that you have to find the amount of T-shirts that should be sold to earn a profit of more than $2,000, you have to find the amount required to earn $2,000 by replacing p with 2,000 and solving for s:
s^2+9s-142=2000
s^2+9s-2142=0
(s+)^2-2142-()^2=0
(s+)^2=2142+()^2
(s+)^2=2142+
(s+)^2=
s+=
s=
s=
s=
s=42
According to this, Reyna needs to sell more than 42 T-shirts to earn a profit of more than $2,000.
