Using the Rule of 70, what approximate interest rate would be needed for an investment of $14,000 to double by the end of 32 years?

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
