Answer: 5% growth (fourth choice)</h3>
the base of the exponent 1.05 is in the form 1+r
1+r = 1.05 which solves to r = 0.05 when we subtract 1 from both sides
Since r is positive, it represents growth.
0.05 = 5/100 = 5%
Answer: 0.36
Step-by-step explanation:
6/10 x 6.10= 36/100
Only a function that actually shows the word "ln" or "log" or "log to the base b" is a log function.
Taking a closer look at #3: y = log 0.25^x, we see that this can be simplified by writing the base (10) as follows: 10 10
and then using y as the exponent of the first 10 and log 0.25^x as the exponent of the second 10:
10^y = 10^(log 0.25^x)
You were not asked to do this, but this discussion may be of interest and help to you down the line.
10^y = 0.25^x
Answer:
9 hours
Step-by-step explanation:
If she makes $ 20 for each car, washing 9 cars in 3 hours would get $ 180.
So she will need to work 9 hours 180 + 180 + 180, washing 9 cars in 3 hours and would get $ 540. This is enough to buy her phone and she will have a surplus of $ 120.
In summary she must work 9 hours
