1st problem:
Use the Pythagorean theorem:
a^2+b^2=c^2
49+361=c^2
c^2=410
c=20.24
The answer is 20m

2nd problem:
First calculate the height using the Pythagorean theorem:
a^2+b^2=c^2
20^2+b^2=625     (i got 20 {radius} by half-ing the base edge length)
400+b^2=625
b^2=225
b=15

Next, solve for the volume:
V=a^2*h/3
V=40^2*15/3
V=1600*5
V=8000

The answer is the second choice or B.

<span>1) Write the equation in slope intercept form if 

Slope=3/5 and intercept is 2
y = mx + b
m = 3/5 and b = 2
so

</span><span>equation in slope intercept 
</span><span>y = 3/5(x) + 2

</span><span>2. Find the x intercept of the line 5x-2y=10

x intercept when y = 0
so
</span>5x-2y=10
5x-2(0)=10
5x = 10
  x = 2

answer
x intercept (2 , 0)

hope it helps
