Answer: the answer is -2
Step-by-step explanation: use slope formula
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.
Answer:
<em>1 cm^2 : 9 m^2</em>
Step-by-step explanation:
The scale factor of an area is the square of the scale factor of a length.
The scale for lengths is 1 cm : 3 m.
You now square that scale to get the scale of the areas.
Scale of areas:
(1 cm)^2 : (3 m)^2
1 cm^2 : 9 m^2
