Area of semi circle: you know the radius is 5. 5^2 * pi = 25pi/2 = 12.5pi
For triangle: bh/2 = (10 * 10)/2 = 50
Add them together: 12.5pi + 50
12.5pi = 39.25
39.25 + 50 = 89.25
It’s closest to D
Draw a cartesian plane, create a graph with the equation x = y^2 - 2
then substitute numbers into the equation so that it is true, to find points on the graph, e.g. substitute y with 1, you get
x = 1^2 - 2
x = 1 - 2 = -1, so when y = 1, x = -1, this point is (-1, 1)
for the next substitute y with 2,
x = 2^2 - 2
x = 4 - 2 = 2, the point is (2, 2)
you might want to try negative values of y
y = -1, x = (-1)^2 - 2
x = -1 the point is (-1,-1)
then plot the points on the graph
Answer:
1/4
Step-by-step explanation:
Answer:
32 ÷ 8 + 1 __IS NOT EQUAL TO__ 3² - 1
4² __IS NOT EQUAL TO__ 4 • 2
3(x - 4 + x) __IS EQUAL__ 3x - 4 + x
when x = 4
15 ÷ (1 + 2) ___IS NOT EQUAL TO_ 15 ÷ 1 + 2
3(x - 4 + x) __IS NOT EQUAL TO__ 3x - 4 + x
when x = 2
y2-y1 -8-24 -32 -1*2*2*2*4 16
M= --------- = ----------- = ------ = --------------- = ------
