Antuan deposited $2590 into a 3 year CD at an interest rate of 2.3% compounded quarterly.
lora16 [44]

Answer:

the interest rate is $183.89 =~ $ 184

Step-by-step explanation:

In this question, Antuan deposited $2590 into a 3 year CD (Certificate of Deposit)  at an interest rate of 2.3% compounded quarterly. We need to find the interest account earned after 3 years.

Formula used will be :

Interest = P ( 1 + r/n) ^ n ^ t - P

Where

P= Principal amount

r= interest rate (in decimals)

n= no of times the interest is compounded

t = no of years

Here we are subtracting P because we only need interest amount and not the future value.

Using this formula and finding the value will be:

P= $2590

r = 2.3 % or 0.023

n = 4

t = 3

Interest = 2590 * ( 1 - 0.023 / 4) ^ 4^ * ^ 3 - 2590

Interest= 2590 (1.071) -2590\\Interest= 2773.89 - 2590\\Interest= 183.89

So the interest rate is $183.89 =~ $ 184

Find the equation of the circle whose center and radius are given.<br> center ( 5.6), radius = 3
topjm [15]

Answer:

(x-5)² + (x-6)² = 9

Step-by-step explanation:

Remember that the equation of a circle is (x - h)² + (x - k)² = r², with <em>r </em>being the radius and <em>(h,k) </em>being the center point of a circle.

Since we are already given <em>r </em>and <em>(h,k)</em>, all we need to do is plug them into the formula to find our equation.
