A principal of $4700 was invested at 4.75% interest, compounded annually.
Kitty [74]

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

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

Where

y = the value of the investment at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount invested

From the information given,

P = $4700

r = 4.75% = 4.75/100 = 0.0475

n = 1 because it was compounded once in a year.

Therefore, the exponential function showing the relationship between y and t is

y = 4700(1 + 0.0475/1)^1 × t

y = 4700(1.0475)^t

Meg invested $16,000 in a savings account. If the annual interest rate is 6%, how much will be in the account in 5 years for qua
nexus9112 [7]

Answer:

In 5 years the account will be $ 21,549.68.

Step-by-step explanation:

Given that Meg invested $ 16,000 in a savings account, if the annual interest rate is 6%, to determine how much will be in the account in 5 years for quarterly compounding, the following calculation must be performed:

16,000 x (1 + 0.06 / 4) ^ 5x4 = X

16,000 x 1,015 ^ 20 = X

16,000 x 1.34685500 = X

21,549.68 = X

Therefore, in 5 years the account will be $ 21,549.68.

natulia [17]

As per the problem,

Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.

We have been asked to find , which expression can be used?

As per the distributive property , we know that

a(b+c)=a.b+a.c

Now apply this on the given expression we get

17. 69 + 17 .31=17(69+31)

Hence the expression , which can be used is 17(69+31)
