The answer is -4k^2 - 21k - 20! so sorry if I’m wrong but it’s the answer I got :>
What was the original container?
Step-by-step explanation:
sinx = a/b
tanx= a/c
cosx= c/b
Answer:
The slope is 0.5 or (1/2)
Step-by-step explanation:
Find the rise over run.
from -3 to -1 and 2 to 3 rises 1 runs 2 so then you divide 1/2 and get 0.5.

Answer:</h3>
unshaded area = 25(4 -π) in^2 ≈ 21.46 in^2
<h3>
Step-by-step explanation:</h3>
Each of the shaded circles has a diameter of (20 in)/4 = 5 in, which also is the width of the enclosing rectangle. Then each circle has a radius of 2.5 in, and an area of ...
A = πr^2 = π(2.5 in)^2 = 6.25π in^2
The four circles together have an area of ...
4A = 4·(6.25π in^2) = 25π in^2
The area of the rectangle is the product of its length and width:
A = LW = (20 in)(5 in) = 100 in^2
Since the circles are shaded, the unshaded area is the difference between the rectangle area and the total area of the four circles:
unshaded area = (100 in^2) - (25π in^2) = 25(4 -π) in^2 ≈ 21.46 in^2
