<u>Answer:</u>
The correct answer option is d. 9.
<u>Step-by-step explanation:</u>
We are given an expression
and we are supposed to simplify it.
We can also write
as
.
We know the power rule
which means that to raise a power to a power you need to multiply the exponents.
So multiplying the exponents to get:

3 gets cancelled by 3 so we are left with:

Therefore, the correct answer option is d. 9.
Answer:
12
Step-by-step explanation:
First figure the ratio of the real building to the model which is 21 divide 3. So the ratio is 1:7, since we're finding the height of the model, we divide 7 by 84 which is 12
Answer:
Second table.
Step-by-step explanation:
A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.
The additive rate of change is determined using the slope formula,

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.
The additive rate of change of this table is

Therefore the second table has an additive rate of change of 3.
