Step-by-step explanation:
The value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286
Rational numbers are numbers written as the ratio of two integers. For example, the fraction 2/7 given is a rational number.
Expressing 2/7 as a decimal number will give;
2/7 = 0.2857142... (It gave repeated decimal values)
Truncating the repeating decimal to the nearest thousandth means writing the decimal to 3 decimal places
0.2857142 = 0.286 (to the nearest thousandth)
Hence the value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286

Let
n-------> the number of nickels
q------> the number of quarters
we know that

so
----> equation A
----> equation B
substitute equation B in equation A
![0.05n+0.25[3n]=1.60](https://tex.z-dn.net/?f=0.05n%2B0.25%5B3n%5D%3D1.60)



Find the value of q

therefore
<u>The answer part a) is</u>
the number of nickels are
and the number of quarters are 
<u>the answer Part b) is</u>
The expressions that represents the number of quarters is
We are given the function:
g(x) = 6 (4)^x
Part A.
To get the average rate of change, we use the formula:
average rate of change = [g(x2) – g(x1)] / (x2 – x1)
Section A:
average rate of change = [6 (4)^1 – 6 (4)^0] / (1 – 0) =
18
Section B:
average rate of change = [6 (4)^3 – 6 (4)^2] / (3 – 2) =
288
Part B.
288 / 18 = 16
Therefore the average rate of change of Section B is 16 times
greater than in Section A.
<span>The average rate of change is greater between x = 2 to x = 3 than between
x = 1 and x = 0 because an exponential function's rate of change increases
with increasing x (not constant).</span>
