Answer:
$6.30
Step-by-step explanation:
The cost of the grapes is ...
(2.5 lb)×($1.48 /lb) = $3.70
After that amount is subtracted from the gift card, the remaining balance is ...
$10.00 -3.70 = $6.30
$6.30 remains on the gift card.

In 2012, the population of a city was 5.43 million. The exponential growth rate was 1.39% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be 9 million?
d) Find the doubling time
a) The exponential growth function is P(t) = where t is in terms of the number of years since 2012 and P(t) is the population in millions.
(Type exponential notation with positive exponents. Do not simplify. Use integers or decimals for any numbers in the equation.)
Answer:
In 2012, the population of a city was 6.03 million. The exponential growth rate was 3.89% per year. Find the exponential growth function. Estimate the population of the city in 2018. When will the population of the city be 8 million? Find the doubling time. The exponential growth function is P(t) = 6.03e^0.0389t, where t is in terms of the number of years since 2012 and P(t) is the population in millions. (Type exponential notation with positive exponents. Do not simplify. Use integers or decimals for any numbers in the equation.) The population of the city in 2018 is 7.6 million. (Round to one decimal place as needed.) The population of the city will be 8 million in about 7.3 years after 2012. (Round to one decimal place as needed.) The doubling time is about years. (Simplify your answer. Round to one decimal place as needed.)

[tex]\frac{n^5}{n-6} * \frac{n^2-6}{n^8}[/tex]
Step-by-step explanation:
Dod you mean
[tex] = \frac{ {n}^{5} }{ {n}^{ - 2} } \times \frac{ {n}^{2 - 6} }{ {n}^{8} } [/tex]
[tex] = {n}^{5 - ( - 2)} \times {n}^{2 - 6 - 8} [/tex]

The temperature of a city doubles during the day, and then decreases by 14.1ºF after the sun goes down. The temperature at the end of the day is −1.7°F. What was the temperature at the beginning of the day? Enter your answer in the box.
The temperature at the beginning of the day was 6.2°F
Let x represent the temperature at the beginning of the day.
Since, the temperature of a city doubles during the day, and then decreases by 14.1ºF after the sun goes down, hence:
Temperature at end of day = 2x - 14.1
Also, the temperature at the end of the day is −1.7°F, hence:
2x - 14.1 = -1.7
2x = 12.4
x = 6.2°F
The temperature at the beginning of the day was 6.2°F

Alek is using synthetic division to divide x^3+4x^2-43x-10 by x-5.
-
-
Which answer is correct?
The answer to the synthetic division is [tex]x^{2}[/tex]+9[tex]x[/tex]-2+0/x-5
A synthetic division is shorthand method used to divide a polynomial function by a binomial in the form x-c where c is a constant
To divide a polynomial function by a binomial x-c, we set up as though we are doing long division in the form,using our question above;
x-5[tex]\sqrt[/tex][tex]x^{3}[/tex]+4[tex]x^{2}[/tex]-43x-10
To divide using synthetic division, we set aside the coefficients of the dividend and the divisor then multiply with the divisor in this form:
5[tex]\sqrt[/tex]1 4 -43 10
5 45 10
1 9 2 0
The quotient would then be based on the above; [tex]x^{2}[/tex]+9[tex]x[/tex]-2+0/x-5
We apply the values under the line as our new coefficients for the quotient but note from answer that the quotient's degrees is one less than the dividend's degrees.
