Answer: 2 times pi times the radius.

The radius is 1.155.

So the answer you will get is 7.25.

the answer would be 7.3 if you want to round it up.

Step-by-step explanation:

If you want to make the pi into your calculator just press shift and press the bottom middle where it has the x10x sign. That is how you get pi.

A graph is shown below. Which function represents the graph?

Ede4ka [16]

Given that the graph of a parabola.

We need to determine the function that represents the graph.

Function of the graph:

From the graph, it is obvious, that the x - intercepts of the graph are $x = -3,x=-5$

Thus, the equation can be written as

$y=(x-(-3))(x-(-5))$

Simplifying the terms, we have;

$y=(x+3)(x+5)$

Multiplying, we get;

$y=x^2+5x+3x+15$

Adding the like terms, we have;

$y=x^2+8x+15$

Writing it as function, we have;

$f(x)=x^2+8x+15$

Hence, the function of the graph is $f(x)=x^2+8x+15$

If EF - 3x - 11, FG = 4x-10, and EG - 28, find the values of x, EF, and FG. The drawing is not to scale.

Gnom [1K]

Answer:

Part 1) $x=7$

Part 2) $EF=10\ units$

Part 3) $FG=18\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

$EG=EF+FG$ ---> by addition segment postulate

we have

$EG=28\ units\\EF=3x-11\\FG=4x-10$

substitute

$28=(3x-11)+(4x-10)$

solve for x

$28=7x-21$

$7x=28+21$

$7x=491$

$x=7$

step 2

Find the value of EF

$EF=(3x-11)$

substitute the value of x

$EF=3(7)-11=10\ units$

step 3

Find the value of FG

$FG=(4x-10)$

substitute the value of x

$FG=4(7)-10=18\ units$
