Answer:

7\frac{1}{3} feet.

Step-by-step explanation:

We have been given that Robin needed 3 2/3 feet of thread to finish a pillow she was making. We are asked to find the length of thread, if she has 2 times as much as thread as she needs.

First of all, we will convert 3\frac{2}{3} into improper fraction as:

3\frac{2}{3}\rightarrow \frac{3*3+2}{3}=\frac{9+2}{3}=\frac{11}{3}

Two times the length of thread would be:

2\times\frac{11}{3}

\frac{2\times11}{3}

\frac{22}{3}

\frac{3*7+1}{3}

7\frac{1}{3}

Therefore, Robin had 7\frac{1}{3} feet of thread.

Find the absolute maximum and absolute minimum values of f on the given interval. (If an answer does not exist, enter DNE.)
vodka [1.7K]

Answer:

absolute max is 120 and absolute min is -8

Step-by-step explanation:

Find critical numbers

f'(x) = 3x^2 - 12x + 9 = 0

= 3(x^2 - 4x + 3) = 0

3(x-3)(x-1) = 0

(x-3) = 0 or (x-1)=0

x = 1,3

Test them!

x<1     Sign of f' on this interval is positive

1<x<3 Sign of f' on this interval is negative

x>3    Sign of f' on this interval is positive

f(x) changes from positive to negative at x = 1 which means there is a relative maximum here.

f(x) changes from negative to positive at x = 3 which means there is a relative minimum here.

Test the endpoints to find the absolute max and min.

f(-1) = -8

f(1) = 12

f(3) = 8

f(7) = 120

The absolute maximum value of f is 120 and the absolute minimum value of f is -8.

The length of a rectangular portrait is 1.5 times the width. The perimeter is 10 feet.
disa [49]
In order to solve the problem above, represent the width by x. With this, the length of the rectangular portrait is 1.5x. The perimeter of the rectangle is two times the sum of the length and width. This translates to, 

                                    2 (1.5x + x) = 10 ft, x = 2 ft.

Thus, the length of the rectangular portrait is 3 ft.
