A circular trampoline has a padded rope that goes aroumd the outside of the frame. The rope is sold for $2.75 per foot and costs $104.50 before tax this trampoline. What is the diameter of the trampoline, to the nearest foot?

The diameter is 12ft.

Step-by-step explanation:

The length of the rope will be equal to the perimeter of the trampoline.

We know that the trampoline is circular, so the perimeter of a circle can be written as

P = 2*pi*r

where r is the radius, and pi = 3.14...

Then we now should find the perimeter.

if 1ft of rope costs $2.75

now, how many times we can fit $2.75 in $104.50?

We look at the quotient

$104.50/$2.75 = 38

So 38 times, this means that the full rope is 38 times 1 ft, or 38 ft long.

Then the perimeter of the circle is 38ft.

P = 38ft = 2*3.14*r

Now we can find the value of the radius:

r = 38ft/(2*3.14) = 6.05 ft

Now, we want to find the diameter, and we know that the diameter is two times the radius, then:

d = 2*r = 2*(6.05ft) = 12.1 ft.

But we want this to the nearest foot, so we should round it down to 12ft.

The diameter is 12ft.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
