Step One
Begin by drawing a line parallel to the x axis. Create it so it goes through (0,1)
This line you have drawn should hit points on the figure at (-5,1) (-2,1) and (3,1)
You now have a figure on the bottom that is a trapezoid. It has 2 small triangles on top of it. We'll talk about them later.
Step Two
Find the area of the trapezoid.
<em>Formula</em>
Area = (b1 + b2)*h/2
h = 1 - - 3 = 4
b1 = 3 - - 8 = 11
b2 = 3 - - 5 = 8
Area = (11 + 8)*4 / 2
Area = (19 ) * 2
Area = 38
Step Three
Find the area of the small triangle on the left.
The base goes from -5 to - 2 which is 3 units.
The height goes from 1 to 3 (using the y axis as a reference) which is 2
Area = 1/2 * b * h
Area = 1/2 *3 * 2
Area = 3
Step Four
Find the area of the small triangle on the right.
The base is 5 (see if you can get 5 as an answer)
The height is 1.
Area = 1/2 b * h
Area = 1/2 5 * 1
Area = 2.5
Step Five
Total Area is found by adding the three areas together.
Total Area = trapezoid + small triangle on the left + small triangle on the right
Total Area = 38 + 3 + 2.5 = 43.5
43.5 <<<< answer
Answer:
5 1/4
Step-by-step explanation:
Answer:
The x-intercept is (-2,0)
The y-intercept is (0,3)
Step-by-step explanation:
An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:
So, the x-intercept is (-2,0).
Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:
Thus, the y-intercept is (0,3).
The answer is D. You’d need to minus the area of the circle away from the area of the triangle to get the area of the shaded region
Answer:
146 is the answer because 180 - 34 = 146. And I did the test and it was right.
I hope this helped:)
