HELP PLS,
Alexandra signed up for a streaming music service where there's a fixed cost for monthly membership and a cost per song downloaded.
Answers
Answer:
D.
Step-by-step explanation:
7.99 is the basic fixed cost per month. this is charged, even if there are no songs (x = 0) downloaded.
and so, 1.75 is the cost per downloaded song in addition to the basic fixed cost. so, yes, the number of downloaded songs has to be multiplied by the cost for a single song to get the total.
and so, 1.75 is the change in the total cost for every automakers download (every time x is increased by 1).

A chef had to fill up 4⁄6 of a container with mashed potatoes. He ended up using 3 2⁄4 pounds of mashed potatoes. How many pounds would he use if he had to fill up the entire container?
Answers
5.25 pounds of mashed potatoes is required to fill the container.
How Many Pounds to Fill the ContainerIn the question, we were told the container was 4/6 filled and the chef used 3 2/4 pounds which is equal to 14/4 pounds of mashed potatoes.
In doing this, we are calculating the volume of the container.
Let's equate this and find how many pounds will fill the container.
[tex]\frac{4}{6}fill = \frac{14}{4} pounds\\ 1 fill = x pounds[/tex]
Let's cross multiply both sides and solve for x.
[tex]\frac{4}{6}fill = \frac{14}{4} pounds\\1 = x pounds\\x = \frac{1 * \frac{14}{4} }{\frac{4}{6} }\\x = \frac{21}{4} = 5.25 pounds[/tex]
To fill the container, we need 5.25 pounds of mashed potatoes.

Answers
The range of the exponential function f(x) is 1 / 32 ≤ f(x) ≤ 16.
How to find the range of an exponential function
Exponential functions are monotonous functions, that is, functions that are increasing or increasing but never both. Functions are defined by the following three features:
Domain - Set of input variables.Range - Set of output variables.Relation - Relations between domain and range.In this problem we find a function with an input variable (x) and an output variable (f(x)). Since exponential functions are monotonous functions we can determine the bounds of the range by the function evaluated at x = - 5 and x = 4. Thus:
f(- 5) = 2⁻⁵
f(- 5) = 1 / 2⁵
f(- 5) = 1 / 32
f(4) = 2⁴
f(4) = 16
The range of the function f(x) = 2ˣ for - 5 ≤ x ≤ 4 is 1 / 32 ≤ f(x) ≤ 16.

Answer: Equation is x+45 = 90
It solves to x = 45
Explanation:
The two angles are complementary, which by definition means they join together to form a right angle. The two pieces x and 45 add to 90 degrees.
To solve the equation x+45 = 90, we subtract 45 from both sides to get x = 45.
As a check x+45 = 45+45 = 90.

Answers
His lifetime earnings when he retires at the age of 68 is $2,817,385.1728.
The total number of years Demarcus will work is 68 - 24 = 44 years.
Now, there are about 52.1429 weeks per year; therefore, the number of weeks in 44 years will be:
44 years × 52.1429 weeks/year = 2294.2876 weeks
We are also told that Demarcus gets paid once every two weeks; this means the number of payments made in 44 years will be:
2294.2876 / 2 = 1147.1438 payments
Since each payment is worth $2,456.00, the total amount earned from 1147.146 payments will be:
1147.146 payments × 2456 per payment = $2,817,385.1728
Hence, Demarcus' lifetime earnings if he retires at the age of 68 will be $2,817,385.1728.

Now, we see from the graph that as x approaches a larger value, y values are getting increasingly negative. This means that as x approaches negative infinity, the values of y approach negative infinity.
In a similar approach, we can see that as the values of x approach positive infinity, the values of y also approach positive infinity.

If the area of the rectangular billboard covered by the ribbon was approximat 3360 square feet, and the width of the billboard was approximately 56 feet, what was the height of this billboard?
Answers
If the area of the rectangular billboard covered by the ribbon was approximately 3360 square feet, and the width of the billboard was approximately 56 feet, the height of the billboard would be 71.25 feet.
What is area?The exact measurement that helps to express the size of a region on a plane or curved surface is thus called as area.
Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
In mathematical terminology, area can be defined as the total space that is taken up by a flat (2-D) surface or shape of a present object.
Here the area of the billboard = 3360 sq feet
Width of the billboard = 56 feet
We know that
area of the billboard = Height of the billboard x Width of the billboard
⇒ Height of the billboard = [Area of the billboard] / [Width of the billboard]
⇒ Height of the billboard= 3360/56
⇒ Height of the billboard = 71.25 feet

Answers
The ending balance for a amount of Rs. 341,000 with a interest rate of 4% for the time period of 3 years is Rs. 381920.
What is interest?
In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed).
Information given in the question,
Principle amount = 341,000
Time period = 3 years
Interest rate is 4 % which can be written as 0.04 in decimals.
We can calculate the ending balance using this formula formula for simple interest:
[tex]S.I. = Principle \times Interest \times time[/tex]
Putting the values given in the question
S.I. = (341000)(0.04)(3)
S.I. = 40,920
Interest is 40,920.
The ending balance is the sum of Principle amount and Interest. So,

How long will it take for a $4000 investment to grow to $5780 at an annual rate of 4%, compounded quarterly? Assume that no withdrawals are made. Do not round any intermediate computations, and round your answer to the nearest hundredths.
Answers
The working equation when dealing with problems regarding compounded interest is
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where A is the future value, P is the principal value, r is the annual rate, and n is the number of compounding periods.
The problem compounds quarterly, hence, we have n = 4.
We derive the working equation to solve for t, as follows:
[tex]\begin{gathered} \frac{A}{P}=(1+\frac{r}{n})^{nt} \\ \ln (\frac{A}{P})=\ln ((1+\frac{r}{n})^{nt}) \\ nt\ln ((1+\frac{r}{n}))=\ln (\frac{A}{P}) \\ t=\frac{\ln (\frac{A}{P})}{n\ln ((1+\frac{r}{n}))} \end{gathered}[/tex]Substitute the values of A, P, n, and r on the derived equation above and solve for t, we get
[tex]\begin{gathered} t=\frac{\ln (\frac{5780}{4000})}{4(\ln (1+\frac{0.04}{4}))} \\ t=\frac{\ln (1.445)}{4(\ln (1.01))} \\ t=\frac{0.368}{4(0.00995)} \\ t\approx9.25 \end{gathered}[/tex]Therefore, the $4000 investment grows to $5780 in 9.25 years.
