the present value of a sum of money is the
amount that must be invested now, at a given
rate of interest, to produce the desired sum at a
later date. find the present value of 10,000 if
interest is paid at a rate of 6.2% compounded
weekly for 8 years.

The present value of 10,000 if  interest is paid at a rate of 6.2% compounded  weekly for 8 years is 6097.56

Explanation:

We know that compound interest is given by  

Where ,  

Where A = final amount (which is given to be = 10000)

       P = Principal amount (which is the present amount which we have to find)

r  = interest rate = 6.2 = 0.062

n = no. of times interest applied per time period = it is given that the interest is applied weekly, so in one year there are 52 weeks so n = 52

t = time period = 8 years

Substituting the given values, we get

P = 6097.5

We get, P = 6097.56 which is the present value of a sum of money

hope this

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
