Answer:
The area is 88.39 cm
Step-by-step explanation:
Here, we want to find the area of the semicircle given that the diameter of the semi circle is 15 cm
We start by getting the radius
Mathematically r = D/2
= 15/2 = 7.5
Area of semicircle is area of circle/2
= (pi * r^2)/2
= (22/7 * 7.5^2)/2 = 88.39 cm
Answer:
a) None
b) (0, -2)
Step-by-step explanation:
The x-intercept is the point at which the line cuts through the x-axis, while the y-intercept in the point at which the line cuts through the y-axis.
a) The line does not cut through the x-axis, thus it has no x-intercept.
b) The line cuts through the y-axis at y= -2, making its y-intercept (0, -2).
Answer: Y=-1 which means on a graph it would be a horizontal line on the point of (0,-1)
Step-by-step explanation:
Answer:
Step 4
part a: no answer yet still having trouble showing my work
part b:
-0.125(x-24)^2+50
-0.125(x-24)(x-24)+50
-0.125(x^2-24x-24x+576)+50
-0.125(x^2-48x+576)+50
-0.125x^2+6x-75+50
-0.125x^2+6x-22
a=-0.125
b=6
c=-22
part c: yes he went through
part d:
plug in roots (4,0) and (44,0)
if x is 4 and y is 0
0=-0.125(4)^2+6(4)-22
0=-2+24-22
0=-2+2
0=0
if x=44 and y=0
0=-0.125(44)^2+6(44)-22
0=-242+264-22
0=-242+242
0=0
