You deposit $60 in an account earning simple interest at an annual rate of 5% after 12 years what is your new balance
Kaylis [27]

Answer:

The total amount accrued, principal plus interest, from simple interest on a principal of $60.00 at a rate of 5% per year for 12 years is $96.

Step-by-step explanation:

Given

Principle P = $60

Rate r = 5% = 5/100 = 0.05

Time period t = 12 years

To determine

New Balance A = ?

Using the formula

A = P(1 + rt)

A = 60(1+(0.05×12))

A = $96.00

Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of $60.00 at a rate of 5% per year for 12 years is $96.

Calculate the distance between the points P=(-9, 1) and C=(−6, 8) in the coordinate plane.
Alekssandra [29.7K]
Using Pythagoras
Distance between P and C = sr[(-6 - -9)^2 + (8 - 1)^2]
= sr(3^2 + 7^2)
= sr(9 + 49)
= sr(58) exactly

What is the nth term in the sequence:<br> 4, 7, 12, 19, 28 <br> Please show working out
3241004551 [841]
                         4, 7, 12, 19, 28
1st difference    +3 +5 +7 +9
2nd difference      +2 +2  +2

This is a geometric sequence

The form is:
                  an² + bn + c
2a is always = to the second difference
2a = 2
a = 1

3a + b = 2nd term - 1st term
3(1) + b = 3
3 + b = 3
b = 0

a + b + c = 1st term
1 + 0 + c = 4
1 +c = 4
c = 3

nth term of sequence {substitute all we have found}
1n² + 0 + 3
n² + 3
