A'B'C' is a dilation image of ABC. Which is the correct description of the dilation?
1 answer:
Answer:
The second option is the answer.
Step-by-step explanation:
The center of a dilation makes all the corresponding vertices coincide at one point if we draw a straight line including that pre image and new image point. All coordinates correspond about Point C. So the first two options are the viable answers.
The blue triangles right side measure is 10 while the smaller triangle right side measure is 5. This means the scale factor is
So our scale factor is 2.
The second option is the answer.

Answer: D)
Step-by-step explanation:
From the given table we can see that this is not representing a linear function as the rate of change is not constant.
So it can be exponential growth function , where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.
Now here at n=1 , f(n)=8
Therefore, A=8
Now, for n=2
By substitute the values of A and b in the above equation, we get the equation
Therefore, the function best shows the relationship between n and f(n) is
, where n is the number of weeks.
Answer:
The distance between x and y on the number line is 2x
Step-by-step explanation:
we know that
If y is the opposite of x
then
The distance between x and y is equal to
