A new online music service has a collection of 1,500 songs. It expects to triple the number of songs each year for the next few

Rzqust [24]

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.

Evaluate 15r -1 when r=5

alukav5142 [94]

Answer:

Step-by-step explanation:

You just have to substitute r with 5.

Now, the equation looks like this:

$15(5)-1$

Next, solve $15*5$ first according to PEMDAS

And $15*5$ equals 75

$\frac{\left[\begin{array}{ccc}1&5\\5\\\end{array}\right] }{75}$

Lastly, do $75-1$ which equals 74

$\frac{\left[\begin{array}{ccc}7&5\\-1\\\end{array}\right] }{74}$

Therefore, 74 is your answer.

One brand of coffee is packaged in cylinders where the height is equal to the radius, r. The volume of the package, in cubic cen

aliya0001 [1]

Answer:

Step-by-step explanation:

This problem is a composition of function defined by C(V(r)), now we have the functions $V(r)= \pi r^{3}$ and $C(V)=3.2V$ , where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,

$C(V(r))=3.2(\pi r^{3} )$

Therefore, the right answer is the last choice.
