Answer:

Step-by-step explanation:
The volume of cone is given by:

where
is the radius of the base and
is the height of the cone.
We need to solve for 
we have 
Multiplying both sides by 3 to remove 
⇒ 
⇒ 
dividing both sides by 
⇒ 
⇒ 
Taking square root both sides:
⇒ 
⇒ 
∴ 
Y=-1/2x+5 because the y intercept of the two points is 5
Answer: g^36
Step-by-step explanation:
I am assuming theres an addition sign between the 3 and 4.
So basically you want to multiply the 5x by both terms so it will end up being
(5x•3) + (5x•4)
Now simplify:
15x+20x
