The perimeter of a rectangle is 14cm. The length of the rectangle is 4 cm more than twice the width. Find the dimensions of the

sasho [114]

Answer:

length = 6 cm

width = 1 cm

Step-by-step explanation:

l = length

w = width

l = 4 + 2w

2(4 + 2w) + 2w = 14

8 + 4w + 2w = 14

8 + 6w = 14

6w = 6

w = 1

find length:

l = 4 + 2(1)

l = 6

The function y = f(x) is graphed below. What is the average rate of change of the

stepladder [879]

Answer:

Average rate of change = 1

Step-by-step explanation:

Average rate of change of a function between x = a and x = b is defined by,

Average rate of change = $\frac{f(b)-f(a)}{b-a}$

We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4

Therefore, average rate of change of the function = $\frac{f(4) - f(2)}{4-2}$

From the graph attached,

f(4) = 4

f(2) = 2

Average rate of change = $\frac{4-2}{4-2}$

= 1

Therefore, average rate of change of the function in the given interval is 1.
