In linear equations, the graph will always be a straight line. In non linear equations, the graph may look like a parabola (curvy instead of straight).

Help me find the arc length of this. Thank you.

The red chord is a diameter of the circle, so the length of the blue arc is half the circle's circumference.

The circumference of a circle with diameter $d$ is $\pi d$ , so the circle has circumference $8\pi$ , and so the arc has length $4\pi$ .

I) there are 360 degrees in a circle. So subtract all the numbers from 360 to get the angle for econ.

That angle is 65 degrees

ii) If 95 degrees represents 228 books, then 360 degrees represents "x" (total) books. So we have an equation:
<u>95</u> = <u>360</u>
228 x

Solve for x, and we get x = 864

iii) The percentage is 80 degrees out of 360 degrees or 2/9 or roughly 0.222 or 22.2%

When 3^2 – 2 + 7 is subtracted from 5^3 – 4^2 + 10, what is the difference?

xxTIMURxx [149]

The difference is 105
3^2 - 2 + 7 =
(3 x 3) - 2 + 7 =
9 - 2 + 7 = 14

5^3 - 4^2 + 10 =
( 5 x 5 x 5) - ( 4 x 4) + 10
125 - 16 + 10 = 119

119 - 14 = 105
