So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: $96\pi =24\pi +x(\frac{4}{3}\pi*3^3)$

Firstly, solve the parentheses: $96\pi =24\pi +x(\frac{4}{3}\pi*27)\\ 96\pi =24\pi +x(36\pi)$

Next, multiply 36 pi and x: $96\pi = 24\pi +36\pi x$

Next, subtract 24 pi on both sides: $72\pi =36\pi x$

Lastly, divide both sides by 36 pi, and your answer will be $2=x$ , or B.

A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million u

EleoNora [17]

Answer:

when the survey was initially conducted the average sales of smartphones was 1.7 million units

Step-by-step explanation:

The average annual sales of smartphones is given by function

$P(n)= 1.7 (b)^n$

Exponential growth function is given by

$f(x)= ab^x$

Where a= initial value

b = growth factor , b= 1+r where 'r' is the growth rate

x is the time period

Now we compare f(x) with P(n)

the value of a= 1.7 that is the initial value.

So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units

Answer:

Angle 2 = 105

Step-by-step explanation:

Since these angles are cut by a transversal the angle from above is congruent to angle #2. You can say the theorem that is used to make these two congruent is the Alternate exterior angles theorem which states this.

Hope this helped!
