Answer:
The area of the circle is 314 in^2.
Step-by-step explanation:
10 inches is the radius.
The formula for the area of a circle is pi times radius squared.
So your equation would be: ![A=\pi (10)^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%2810%29%5E2)
10^2 = 100
Then you do
or 3.14 times 10 = 314.1592654 or just 314.
Hope I helped ya.

Answer:
f(x) = -4x + 12
Step-by-step explanation:
y - 2x = -6x + 12
+2x +2x
f(x) = -4x + 12
Answer:
Step-by-step explanation:
To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side
![44 - 4 = -2y ----equation 1](https://tex.z-dn.net/?f=44%20-%204%20%3D%20-2y%20----equation%201)
![10 = 7x + 4y --- equation 2](https://tex.z-dn.net/?f=10%20%3D%207x%20%2B%204y%20---%20equation%202)
We can simply evaluate equation 1 to have
![40 = -2y\\y = 40/-2 = -20\\](https://tex.z-dn.net/?f=40%20%3D%20-2y%5C%5Cy%20%3D%2040%2F-2%20%3D%20-20%5C%5C)
y = -20
From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.
1) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum simple interest after 6 years are <u>R25,400</u> and <u>R5,400</u> respectively.
2) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum compound interest after 6 years are<u> R26,045.20</u> and <u>R6,045.20</u> respectively.
<h3>Data and Calculations:</h3><h3>Simple Interest:</h3>
Principal = R20,000
Investment period = 6 years
Interest rate = 4.5%
Simple interest for 6 years = R5,400 ($20,000 x 6 x 4.5%)
Principal + Interest = R25,400 (R20,000 + R5,400)
<h3>Compound Interest:</h3>
Principal = R20,000
Investment period = 6 years
Interest rate = 4.5%
N (# of periods) = 6 years
I/Y (Interest per year) = 4.5%
PV (Present Value) = R20,000
PMT (Periodic Payment) = R0
<u>Results</u>:
FV = R26,045.20
Total Interest = R6,045.2
