For starters,
Consider the th partial sum, denoted by :
Multiply both sides by :
Subtract from this:
Solve for :
Now as , the exponential term will converge to 0, since if . This leaves us with
Answer:
Step-by-step explanation:
race entry costs 55, they use 15 of it to cover costs so they get 55-15 = 40 per entry
x = race entries
equation becomes 55000>= 40x +10000
45000>= 40x
x >= 45000/40 >= 1125
they need at least 1125 race entries to make $55,000
This is the formula for the surface area where r is the radius and h is the height. Finding the surface area will determine how much wrapping paper Jill needs (in inches squared).
The base measures 4 inches across. This means that the diameter is 4 inches. The radius is half the diameter (always). Thus, the radius is 2 inches. This means that r=2
The height is 10 inches. This means that h=10
The questions says to use 3.14 for π.
Use a calculator for this. Doing this by hand will take a painful amount of time.
This was what I got from a calculator. I did not round at all.
The surface area is 150.72 inches squared. Thus, Jill will need 150.72 inches squared of wrapping paper. I hope this is what you needed to help you understand! :)
