We know, final dimension = initial dimension * dilation factor
= 3 * 1/5 = 0.6
& 6 * 1/5 = 1
In short, Your Answer would be Option D) <span>0.6 ft × 01 ft

Turning up the edges of the sheet metal will result in the 20 inches of
metal being divided into x inches of the first side, then the unknown
width of the gutter (let's call it "y") and then again x inches for the
second side.
As a picture:
x|______|x/y
As a formula:
20 = x + y + x = 2x + y
Resolving this to y we get:
20 - 2x = y
and switching it around:
y = 20 - 2x,
Now for part b) of your question:
The area of the gutter's cross-section is its width (y) multiplied with its height (x).
A(x,y) = x * y
If we use our result from a) to eliminate y then we can see that
A(x) = x * y = x * (20-2x) = 20x-2x^2
So I'd say that the answer to part b) should be:
A(x) = 20x - 2x^2
Answer:
6/2.
Step-by-step explanation:
1 whole is 2/2.
3 times 2/2 is 6/2.
An improper fraction means the numerator is bigger then the denominator, so we know that 6/2 is even an improper fraction.
2(cos2x - sin2x)
Step-by-step explanation:
Y = sin2x + cos2x
Differentiate wrt x
dy/dx = cos2x . 2 - sin2x . 2
= 2(cos2x - sin2x)
