Answer:
57.75 yards yard will she makes 14 panels.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the statement: Katrina uses 4.125 yards of fabric for each curtain panel she makes.
To find the how many yard will she makes 14 panels.
By proportion definition,

By cross multiply we have;

Simplify:
x = 57.75 yards.
therefore, 57.75 yards yard will she makes 14 panels.
I believe it’s D I hope this helped
(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)
The answer is D, I hope this helps
