Answer:
49Pi cm^2
Step-by-step explanation:
Area of a circle = Pi r^2
Radius r = 7
Area = Pi x 7^2
= Pi x 7 x 7
= 49Pi cm^2

Answer:
$536.25
Step-by-step explanation:
First, you need to find what 7.5% of $2,200 is,
(2200/100)7.5=165
then to find how much interest has accumulated over 3 1/4 year you need to multiply the one-year interest rate by the 3.25
(165)3.25=536.25
Answer:
<h2>f(x) = 3x + 4</h2>
Step-by-step explanation:
f(x + 1) = 3x - 7
f(x) = f(x + 1 - 1) = 3(x - 1) + 7 = 3x - 3 + 7 = 3x + 4
Check
f(x) = 3x + 4
f(x + 1) = 3(x + 1) + 4 = 3x + 3 + 4 = 3x + 7 CORRECT
