1. If a and b vary inversely and b = 8 when a = 6:
b = k/ a
8 = k / 6
k = 6 * 8
k = 48
Function is:
b = 48 / a
2. When a = 30:
b = 48 / 30 = 8/5
b = 1.6

Your father earned​ $34,000 per year in 1984. To the nearest​ dollar, what is that equivalent to in 2014 if the CPI in 2014 is 2
xeze [42]

Answer:

The answer is : 70288.46

Step-by-step explanation:

Your father earned​ $34,000 per year in 1984.

The CPI in 2014 is 215 and the CPI in 1984 is​ 104.

The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.

The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)

34000\times\frac{215}{104} = 70288.46

NEED HELP ASAP!!!! PLEASEEE
nikdorinn [45]

The first answer of the missing blank is 4/5.

The second answer of the missing blank is 2.

The third answer of the missing blank is 25.

*For all of these solutions, I will be using the common rules for logarithms.*

Solution for the first question:

Log9^4/5 must equal log9^4-log9^5, or it could also equal the more proper version, which is simplified: 2log9^2-log9^5.

Solution for the second question:

Log3^22 must equal log3^11+log3^2, if you break it down.

Solution for the third question:

Log9^25 must equal 2log9^5 because it will be like this when simplifying it:

log9^25=2log9^5

log9^5²=2log9^5

2log9^5=2log9^5

These are all of the step-by-step procedures for all three of these given questions. Anyways, I hope that this helped you!
