Answer:
b. 12π
Step-by-step explanation:
C= 2πr
R= D/2= 12/2= 6
C= 2x3.14x6
2x6= 12
C= 12π
The correct answer would be -1/4. I am sorry that is not one of the choice but by doing the math correctly, -1/4 is the correct answer.
Answer:
$0.5
Step-by-step explanation:
formula ; y = kx
where ; y = $1.5
x = 3 pounds of bananas
k = constant of proportionality
Step 1. Do the equation based on the data given
y = kx
$1.5 = k3
Step 2. Compute the mathematical equation. Divide both sides by the coefficient of 3.
<u>$1.5</u> = <u>k3</u>
3 3
k = .5
Answer; $0.5 is the constant of proportionality cost in dollars per pound of banana.
Format: y = mx + b
y = 2x + b
Plug in the point
-1 = 2(5) + b
-1 = 10 + b, b = -11
Answer: y = 2x - 11
