Step-by-step explanation:
Is there a picture that goes along with this question.
Answer:
C.
x=3
Notice how the line is reflected at a vertical line (not shown) at (3, 0)
Therefore x=3 since that is the line where the reflection occurs.
Step-by-step explanation:
Answer:
1/4x -3
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y =4x+12
Exchange x and y
x = 4y+12
Solve for y
Subtract 12 from each side
x-12 = 4y+12-12
x-12 = 4y
Divide by 4
(x-12)/4 = 4y/4
The inverse is
1/4x -3
The angle in the diagram is 90 degrees, while the circumferential angle is 360 degrees, so 1/4 of the circle is blank, and the shaded region is 3/4 of the circle. The area of the circle is pi*r^2=36pi cm^2. While the region is only three quarters of it, so the area is 3/4*36pi=27pi cm^2.
