Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
Graphing the 2 parabolas choice c is narrower.
c
We define the variables:
p: cost of bushel of peaches
w: cost of watermelon
We wrote the system of equations:
12p + 5w = 150
15p + 8w = 198
We can represent the system in matrix form as
Ax = b
Where,
A = [12 5; 15 8]
b = [150; 198]
x = [p; w]
Answer:
3pi
Step-by-step explanation:
First find the area of the entire circle
A = pi r^2
A = pi * 2^2
A = 4 pi
We know that this is 3/4 of a circle so multiply the area by the fraction of the circle
3/4 * 4 pi
3 pi
