The points of inflection are the points where the slope of f'(x) is zero
basically where the horizontal tangents are
at x=2 and x=4
Answer:
21
Step-by-step explanation:
A=1/2bh
252=1/2(24)(h)
multiply 1/2 and 24
252=12(h)
divide ( 252/12 12/12)
h=21
Answer:
No; corresponding angles are not congruent

Answer:
A ) 6
Step-by-step explanation:
The formula for Average rate of change is:
Aroc = change in y / change in x.
Aroc = y2-y1 / x2 - x1
The first point will be (x1,y1), and second will be (x2,y2).
x1 is 0, and when the x value is at 0, the y value is at -7, so the coordinate point is (0, -7).
For the second point, x = 2, and the corresponding y value is 5. So you just simpliy plug everything into the formula to find AROC:
= 5 - (-7) / 2 - 0
= 12 / 2
= 6
The formula for the area of a circle is PI x radius^2.
To find the area of the sector, you would multiply the area by the ratio of the the sector angle over 360.
The formula would become PI x r^2 x 30/360.
The 2nd choice is correct.
