The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions

Answers

Answer 1

Answer:

Step-by-step explanation:

L = W+9

area = LW = 36

(W+9)W = 36

W²+9W-36 = 0

W = -12, 3

-12 is an extraneous solution, so W = 3 inches

L = W+9 = 12 inches

what is the value of d/dx(1/x) at x=6 ?​

Answers

If you know your derivative rules, then

d/dx [1/x] = -1/x ²

so that when x = 6, the derivative has a value of -1/36.

If you have to use the definition of the derivative, then

d/dx [1/x] = lim {h → 0} (1/(x + h) - 1/x) / h

… = lim {h → 0} (x - (x + h)) / (hx (x + h))

… = lim {h → 0} (-h) / (hx (x + h))

… = lim {h → 0} (-1) / (x (x + h))

… = -1/x ²

and at x = 6, you again get -1/36.

Alternatively, use the definition of the derivative at a point:

d/dx [1/x] (6) = lim {x → 6} (1/x - 1/6) / (x - 6)

… = lim {x → 6} ((6 - x) / (6x)) / (x - 6)

… = lim {x → 6} -(x - 6) / (6x (x - 6))

… = lim {x → 6} (-1) / (6x)

… = -1/36

What percentage of his monthly budget does Doug put in savings?

O A. 13%

B. 6%

C. 11%

D. 16%

To get the percentage of his monthly budget does Doug put in savings, first we need to get the total savings

Total savings = 403+806+868+496+341+186

Total money = $3100

Amount spent on savings = $341

Percentage savings = amount spent on savings/Total money × 100%

Percentage savings = 341/3100 × 100

Percentage savings = 341/31

Percentage savings = 11%

Hence the percentage of the total money spent on savings is 11%
