The amount of energy it takes to run a race is most likely to be a function of the; D: Length of the Race

<h3>How to find amount of energy?</h3>

We want to basically find the factor that influences the amount of energy expended by a sprinter.

Now, formula for potential energy is;

P = mgd

where;

m is mass

g is acceleration due to gravity

d is distance covered

Now, the only option that falls into the input that affects energy expended is the distance covered. This is true because the more the distance covered, the higher the energy expended.

how much must you deposit in an account that pays 8% interest,compounded monthly to have a balance of $1000 after three years?

<h3>Answer: 787.25 dollars</h3>

=============================

Work Shown:

A = final amount after t years = 1000

P = initial deposit = unknown

r = interest rate in decimal form = 0.08

n = compounding frequency = 12

t = number of years = 3

-----

A = P*(1+r/n)^(n*t) is the compound interest formula

1000 = P*(1+0.08/12)^(12*3)

1000 = P*1.27023705162066

1.27023705162066P = 1000

P = 1000/1.27023705162066

P = 787.254629932364

P = 787.25 rounding to the nearest penny

----

note: this assumes that the interest rate stays at 8% the entire three year period; also, you cannot withdraw any money from the account during this time period.
