Answer:
Amplitude 3; midline y=2
Step-by-step explanation:
The midline is the mean of both ends of the function in the graph.

The amplitude is the vertical distance between the midline and one of the end points.

(sorry for the basic math, i just want to make sure you know where im getting the values from)
To solve this, you have to know the formula for the area of a trapezoid:

In this question:
base 1 = 25
base 2 = 35
height = 12

The area is
360
Answer:
simple follow me
Step-by-step explanation:
2(4y-7)+9y=-31
8y-14+9y=-31
<u>y=</u><u> </u><u>-</u><u>1</u><u>7</u>
<u>x=</u><u> </u><u>-</u><u>7</u><u>5</u>
This isn't to diffuclt. So, to the formula for the area of a circle is

, or instead of r, you can put D, which is r times 2
The diameteris 2.5, so, the answer would be
pi times 2.5, where pie = 3.14
So, the answer is 2.5 * 3.14 = 7.85 or 7.9
