Answer:

The formula that relates circumference and radius is $C=2\pi r$ .

Step-by-step explanation:

The circumference of a circle is calculated by the formula

$C=2\pi r$

Where,

C is circumference of the circle.

r is radius of the circle.

π is 22/7 or 3.14.

In the given options π is not missing. So, all the given options are incorrect.

Therefore the formula that relates circumference and radius is $C=2\pi r$ .

If the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb, how much work is needed to stretch it 18 in.

Blababa [14]

If the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.lb.

Given that work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb.

We are required to find the work that is needed to stretch 18 inches beyond its natural length.

Multiplication is basically finding out the product of two or more numbers.

Work required to stretch the spring 2 feet beyond its natural length=9 ft. lb.

So, to find the work that is required to stretch the spring 18 feet beyond its natural length, we have to multiply 9 with 9 which will give us 81. So the work required is 81 ft.lb.

Hence if the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.-lb.

What is the average rate of change of f<br> over the interval (-5,0]?<br> Give an exact number.

Paraphin [41]

Answer:

Average rate of change = 0.6

Step-by-step explanation:

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

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

From the graph attached,

f(-5) = 0

f(0) = 3

Average rate of change of the graph between x = -5 and x = 0,

Average rate of change = $\frac{3-0}{0-(-5)}$

= $\frac{3}{5}$

= 0.6

Therefore, average rate of change of the given function between x = -5 and x = 0 is 0.6.
