Answer:
Step-by-step explanation:
The growth factor is 1.06.
The year is 2020 - 1978 = 42.
This is exponential growth as the growth factor is > 1.
The equation is V = 40000(1.06)^42
V works out to $462,281
Answer:
C
Step-by-step explanation:
Given the logarithmic equation

First, notice that

So, there is no possible solutions, all possible solutions will be extraneous.
Solve the equation:

then

Hence,
and
are extraneous solutions
Answer:no
Step-by-step explanation:
5(3(10)+8)
5(30+8)
5(38)=190
8(10)+8
80+8
88
88≠190 so no
