Answer:
R(t)=10+0.50t
Step-by-step explanation:
His rate is based on time, for the first side of the equation.
His beginning pay would be 10, so 10 would act as the y intercept. The rate increases by 0.50, so for every year (t) it would increase by 0.50, why you add 0.50 and multiply by the amount of years he works.
Answer:
Suppose the next case.
You want to buy an object from another state or country, you know that the cost of this object is C, and for bringing it from another place, you need to pay a tax, such that you do not know the exact value of the tax, you know that this can be between 3% and 9%.
Then the tax can be written as:
6% ± 3%
then the error is 3%, this means that the percent error is:
(3%/6%)*100% = 50%
Then you know that there is an error of 50% in the tax.
This can be helpful so you can estimate the maximum and minimum cost of tax that you will pay for this purchase.
Also there are a lot of situations where the percent error give us a lot of information.
"a measure of 10 cm with an error of 1 cm"
The percent error is: (1cm/10cm)*100% = 10%
And in a measure of 3cm with an error of 1cm we have:
(1cm/3cm) = 33.33%
In both cases we have the came error, but different percent error.
Then the percent error also tell us how much the error affects our measure.
1 kg is equal to 1,000 g. So, in order to convert, you need to multiply 20x1,000. To get 20,000 g.
Answer:
Power property for both
Step-by-step explanation:
The power property of logarithms says that if there is an exponent in a logarithm, then that exponent can be pulled to the front.
In the first question, 5 is at the front of the logarithm because it has been pulled from 3. If you move the 5 back to the 3, it would be 3^5, which is 243.
In the second question, 2 is at the front of the logarithm as it has been pulled from the 9. If you move the 2 back to the 9, it would be 9^2, or 81.
Example:
log10^2 would be equal to 2log10.
Answer:
Because here score is 575 she must pay 2365 per mo according to the table
If her score were 850 she would pay 1685 per month
So the difference in the two rates is:
2365 - 1685 = 680 a month more because of the low credit score
