Answer:
Option C.(-2, 8)
Step-by-step explanation:
we have
y=f(x) ----> the parent function
y=2f(x) ---> the new y-value will be 2 times the original value
The rule of the transformation of f(x) to 2f(x) is
(x,y) -----> (x,2y)
substitute the given value
(-2,4) ------> (-2,2(4))
(-2,4) ------> (-2,8)
Answer:
Arc length = 9.42 cm
Step-by-step explanation:
First you need the circumference of the circle
r = 6
C = 2* pi * r
C = 2 * 3.14 * 6 = 37.68
To find the length of the arc, we need to know the central angle. IN this case it is 90 degrees (notice the right angle of the triangle).
To find the length of the arc Arc length = (central angle in degrees/360) * C
Arc length = 90/360 * 37.68
Arc length = 9.42 cm
The Original length of each side of square was 14.25 inches.
Step-by-step explanation:
Perimeter of a square is given by:
Perimeter = 4 * side
Let x be the original length of each side of square
So
decreasing 2 inch will mean
Perimeter of square after reducing 2 inches from each side
So,
The Original length of each side of square was 14.25 inches.
