Jonah collects rainwater in a large barrel that weighs 30 pounds. When there are 10 gallons of water in the barrel, the total we

Serjik [45]

The first thing we are going to do for this case is define variables.
We have then:
x: number of gallons of water
y: total weight
We then have an equation of the form:
$y-yo = m (x - xo)
$
Where,
$m = (y2 - y1) / (x2 - x1)
$
Substituting values:
$m = (196.8 - 113.4) / (20 - 10)

m = 8.34$
We choose an ordered pair:
$(xo, yo) = (10, 113.4)
$
Substituting values:
$y-113.4 = 8.34 (x - 10)
$
Rewriting:
$y = 8.34x - 83.4 + 113.4

y = 8.34x + 30$
Answer:
y = 8.34x + 30

What is the Compound interest on a 10,000 investment the earns 6% compound monthlyfor5 years

Vlad1618 [11]

Answer:

The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest

Step-by-step explanation:

So the formula for this would be:

A = P(1+r/n)^nt

A = the amount of your principal plus interest, which is the total

P = stands for the principal, which is your original amount invested

r = shows the interest rate in decimal form

n = stands for the number of compounding periods

So to solve for the compound interest we would plug in our numbers in replacement for the letters
