In which quadrant does the point (13, 18) lie
Dahasolnce [82]

Answer:

Quadrant 1

Step-by-step explanation:

how I understood this is first understanding how a graph works. Once you understand that you can count 13 horizontal on the "X" Axis, then go 18 up on the "Y" axis. you should get a point in the upper left area and that area is called Quadrant 1. Say if 13 was negative instead of going horizontal east you would go horizontal west. And the point should end up in Quadrant 2. Any more questions feel free to ask me below.

Vishal deposits $65 into a new savings account. The account earns 7.5% interest per year. No money is added or removed
Black_prince [1.1K]

Answer:

$79.23 After 3 years

Step-by-step explanation:

Use I P R T it's a method for simple interest

I = Interest

P = Amount of money

R = Percent in decimal

T = Time in years

Answer:

I = x (we dont know yet)

P = $65

R = 7.5% = 0.075

T = 3 years

Steps:

1. Set up your numbers with the method I P R T.

2. $65 will be your amount of money.

3. 7.5% needs to be converted because you will need to multiply later on in the problem. Simply move 2 places to the left to convert your percent into a decimal.

4. They want to know the total amount of money in his account at the end of 3 years. So 3 years will be your time in years.

5. After setting up your problem you need to multiply your Amount of money x percent as decimal x time in years.

65(0.075)(3)=14.63\\ Interest\\

6. After you find your interest you need to add your amount of money + interest.

65 + 14.63 = 79.23 Money after 3 years

hope this helped

What annual investment is required at 8% per year compounded annually to accumulate to $100,000 at the end of 20 years?
Soloha48 [4]
P = $ 38,461.54

Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation

P = 100000 / ( 1 + (0.08 × 20)) = 38461.538461538
P = $ 38,461.54

The principal investment required to get
a total amount, principal plus interest, of $ 100,000.00
from simple interest
at a rate of 8% per year
for 20 years is $ 38,461.54.
