Answer:
The multiplicative rate of change is 
Step-by-step explanation:
You are given the function

First, use the following property of exponents

So, your function is

If the exponential function is written in the form

then b is the multiplicative rate of change for this exponential function.
In your case, the multiplicative rate of change is 
Answer:
the 3 sides of the triangle are 105 ft, 40 ft and 70 ft.
Step-by-step explanation:
the perimeter is the sum of the 3 sides of the triangle
add the parts of the ratio 21 + 8 + 14 = 43
divide the perimeter by 43 to find the value of one part of the ratio
= 5 ft ← 1 part of the ratio, hence
21 parts = 21 × 5 = 105 ft
8 parts = 8 × 5 = 40 ft
14 parts = 14 × 5 = 70 ft
the 3 sides of the triangle are 105 ft, 40 ft and 70 ft
we have

Step 
<u>Clear the variable y</u>

Adds
both sides


Step 
<u>Convert in function notation</u>
Let


therefore
<u>the answer is</u>

To find the answer, you should divide 405 by 50 to find the mass of one coin. The formula should look like this:

= 8.1
The exact mass is 8.1 grams, but because you want an estimate, the answer should be
About 8 grams for the mass of 1 one-dollar coin
well if it asks you to send to 4 people and there are 8 generations which includes yours that mean
1 sent to 4 - 4 recived
4 send to 4 each = 16 recived + the 4 before = 20 (generation 2)
16 send to 4 = 64 + 20 = 84 (generation 3)
64 send to 4 = 256 + 84= 320 (g4)
256 send to 4 = 1024 + 320 = 1344 (g5)
1344 s t 4 = 5376 + 1344= 6730 (g6)
so on and so forth till generation 8
