Answer:
Step-by-step explanation:
The zero of a function is also known as the x-intercept of a function. The x-intercept of a function exists where y = 0. So we will begin by setting each of those lines = 0:
4x - 20 = 0 and -1/2x + k = 0 and then solve each for x:
4x = 20 so
x = 5 and
-1/2x = -k and
1/2x = k so
x = 2k. Now we set the 2 x expressions equal to each other and solve for k:
5 = 2k so
k = 5/2
20; make both equations equal so whatever you plug in for x will be the same
2(4x+10)=8x+k
8x+20=8x+k
k=20
The formula to find the area of a circle is A=r^2pie
Answer:
x = 113
Step-by-step explanation:
The corresponding angles in both triangles are congruent
Hence x = 113
The center is the midpoint of the diameter.
The coordinates of the midpoint if the endpoints are (x₁,y₁) and (x₂,y₂):
The answer is C.
