Answer: y = (3^(x-1))*1500
Step-by-step explanation:
We want the relationship
y = f(x)
where y is the number of songs, and x is the number of years.
We know that in the first year, x = 1, the site has 1,500 songs.
The next year, x = 2, the number of songs is tripled, then we will have:
1,500*3 = 4500 songs.
The next year, x = 3, we will have: 3*(3*1500) = (3^2)*1500.
when x = 4, the number is tripled again:
3*(3^2)*1500 = (3^3)*1500
We already can see the pattern, for the year x, the site will have:
y = (3^(x-1))*1500 songs.
This is the equation we are looking for.

You have 64 grams of a radioactive kind of strontium. If its half-life is 6 hours, how much will be left after 3 hours?
Answer: 48 grams
Step-by-step explanation:
The half-life of an element refers to the amount of time that it takes for half of it to decay.
For instance, if the half life is 2 hours and the element weighs 12 g, the element will only weigh 6g after 2 hours.
The half-life of the above is 6 hours, in 3 hours therefore, it would only have lost of the half that it would have lost in 3 hours which means it would have lost only a quarter.
= 64 * ( 1 - 1/4)
= 48 grams

A swimming pool measures 25.8 meters by 11.9 meters. It is filled with water to a depth of 1.1 meters. The pool is emptied by a tube that emits 29.8 liters per second. Estimate the approximate time required to empty the pool
Answer:
11 Seconds
Step-by-step explanation:
Swimming pool volume:
25.8 × 11.9 × 1.1 = 337.722
Time to empty pool:
337.722 ÷ 29.8 = 11.3329530201 ≈ 11 seconds

You have an annual salary of $85,063. Your monthly expenses include a $1,555 mortgage payment, a $274 car lease payment, $139 in minimum credit card payments, and a $179 payment on your student loan. Calculate your DTI (debt-to-income) ratio as a PERCENTAGE
Answer:
DTI ratio in percentage = 30.29%
Step-by-step explanation:
Annual salary = $85,063
This means that gross monthly pay = 85063/12 = $7088.58
Now,
Total monthly debt payments = 1555 + 274 + 139 + 179 = $2147
Debt to income ratio = (2147/7088.58) × 100% = 30.29%

The face of triangular-shaped guitar has an area of 52 square inches and the height of 13 inches. What is the length
of the guitar?
Answer:
Base = 8
Step-by-step explanation:
Area of a triangle can be calculated as:
Area = 0.5 x Base x Height
The values of the area and the height are given in order to find the length.
A= 52 in^2
Height= 13
First we have to find the base or the length. Using the values above we can set up the equation as:
1. 52= (0.5)(13)(b)
2. 52/0.5(13)
3. b=8
Answer: The length of the guitar or the base would be 8 inches.
I hope this helps and for future problems regarding this topic use the formula above!!
Formula: 0.5 x Base x Height

What is the rate of change of the function described in
the table?
A. 12/5
B. 5
C. 25/2
D. 25
Answer:
B. 5
Step-by-step explanation:
This table does not describe a linear relationship. This is because the table does not have a constant rate of change; between the first two points, the function changes by
(1/2 - 1/10)/(0--1) = (5/10 - 1/10)/(1) = 5/10 - 1/10 = 4/10 = 2/5
Between the second two points, the function changes by
(5/2-1/2)/(1-0) = (4/2)/1 = 4/2 = 2
Comparing the first two y-coordinates, we have 1/10 and 1/2 = 5/10. This is the result of multiplication by 5.
Comparing the second two y-coordinates, we have 1/2 and 5/2. This is the result of multiplication by 5.
Comparing the rest of the y-coordinates, we can see that each time, the y-coordinate is multiplied by 5. This means the rate of change is 5.

If a car can travel 78 miles using 3 gallons of gas, what is the unit rate?
Answer:
26
Step-by-step explanation:
Well since a car can travel 78 miles Using 3 gallons
78/3=26
26 miles for each gallon
Answer:
26
Step-by-step explanation:
The unit rate refers to the distance the car can travel using 1 gallon of gas. One way to solve this is to create an algebraic equation like [tex]78=3x[/tex]. Then, to find the unit rate isolate x by dividing both sides by 3. This means that the unit rate is 26.
Rose is 5 years older than Milton. Rose's age is 10 years less than four times Milton's age. The system below models the relationship between Rose's age (r) and Milton's age (m): r = m + 5 r = 4m – 10 Which is the correct method to find Rose's and Milton's ages? Solve m + 5 = 4m – 10 to find the value of m. Solve r + 5 = 4r – 10 to find the value of m. Write the points where the graphs of the equations intersect the x-axis. Write the points where the graphs of the equations intersect the y-axis.

Find the volume of the cylinder height 10 in base radius 3 in
Answer: 282.60in³
Step-by-step explanation:
When calculating the volume of a cylinder, the formula to use is:
= πr²h
where,
π = 3.14
r = radius = 3 in
h = height = 10 in
Volume = πr²h
= 3.14 × 3² × 10
= 282.60
Therefore, the volume of the cylinder is 282.60in³
The price of an mp3 player is reduced by 60%. The expression c – 0.6c represents the sale price. Which represents an equivalent expression to determine the sale price?
Answer:
0.4c
Step-by-step explanation:
Given that :
Price of mp3 is reduced by 60%
Let initial price of mp3 = c
Discount on price = 60% = 0.6
Discounted price = initial price - discount on price
Discounted price = c - 0.6c
Discounted price = 0.4c
