You can use the special right triangles for this equation. Since the side lengths are 3 and 4, the hypotenuse of the triangle would be 5, or you can use the equation a2 + b2 = c2, 3^2 + 4^2 = c2, 25 = c2, c=5
A. (-2,3) because Rectangle ABCD is dilated by a scale factor of 1/2.
Answer:
-4
Step-by-step explanation:
Rewrite 16 as 4 squared
Pull terms out from under the radical, assuming positive real numbers
-1 x 4
Then you get the answer -4
Answer: $84
Step-by-step explanation: 48/4=12 12x7=84
Answer:
Option c is right.
Step-by-step explanation:
Given is a parabola y =x^2
From that transformation is done to get parabola as
y =(0.2x)^2
We find that instead of x here we use 0.2x
i.e. New x = 5 times old x
Hence there is a horizontal expansion of scale factor 5.
We can check with any point also
When y =4, x=2 in the parent graph
But when y =4 , we have x = 10 in the new graph
i.e. there is a horizontal expansion of scale factor 5.
