Answer:
Triangle ABC is dilated is dilated with a scale factor of ⅓ with the center of dilation at the point (3,4) resulting in triangle DEC
Step-by-step explanation:
From triangle ABC,
|AC|=3 units
From triangle DEC,
|EC|= 1 unit
Since the two triangles are similar, we can find the scale factor using the ratio of the image length over the corresponding object length.
Let us substitute the values to get:
When we trace through AD and EB, they will meet at C. Hence C(3,4) is the center of dilation.

Answer:
Domain = 1 to 7
Range = 4 to 28
Step-by-step explanation:
Given that:
Number of wheels used is a function of number of cars manufactured.
Number of wheels present = 28
1 car uses 4 wheels
2 cars use 8 wheels.
3 car uses 12 wheels
and so on.
Let the function be of the form:
Domain of the function is the value of that can be given as valid input to the function.
Range of the function is the value of that can be output of the function.
Let be the number of cars manufactured.
Then value of is nothing but
times 4.
We are given that maximum value of can be 28.
Therefore, maximum value of input can be 7.
Minimum number of wheels can be 4 to make a minimum of 1 car.
Therefore domain is 4 to 28 and range is 1 to 7.
