How i would solve it is
1. 72.6-35=37.6
2. 37.6/.05=752
and for April you can do the same process phone bill - 35 for usage then divide the answer by .05

LuckyWell [14K]

Answer:

50 in ^3

Step-by-step explanation:

V = 1/3 pi r^2 h

We know that pi = 3  

the diameter is 5 so the radius is 1/2 the diameter of 5/2 = 2.5

The height is 8

V = 1/3 ( 3) ( 2.5)^2 ( 8)

V = 50 in ^3

How does f(x) = 3 ^x change over the interval x = 4 to x= 5
zloy xaker [14]

Answer:

f(x) = 3^x increases steadily on the interval [4,5].

Step-by-step explanation:

This exponential function f(x) = 3^x has a positive base (3) which is larger than 1.  Thus, this function continues to increase as x increases, including the case where x increases from 4 to 5.

He system of equations below has no solution.
vesna_86 [32]

a linear combination can be:

(a + b)*(4x + 15y) = a*12 + b*15

<h3>How to solve the given system of equations:</h3>

Here we have the system of equations:

(2/3)*x + (5/2)*y = 15

4x + 15y = 12

To solve the system of equations, we first need to isolate one of the variables in one of the equations, I will isolate x on the second equation.

4x = 12 - 15y

x = (12 - 15y)/4

Now we can replace that in the other equation:

(2/3)*x + (5/2)*y = 15

(2/3)* (12 - 15y)/4 + (5/2)*y = 15

Now we can solve that for y.

2 - (10/4)*y + (5/2)*y = 15

2 = 15

That is a false equation, then we conclude that the system of linear equations has no solutions.

This means that the two lines are parallel lines, then a linear combination can be:

(a + b)*(4x + 15y) = a*12 + b*15

Where a and b are two real numbers.

Please help. <br><br> Correct answer will get brainliest and full ratings.
irina1246 [14]
Hope this helps but I think the answer is A.To find this look at the points on the graph and find out what their ordered pairs are. Once you do that look at the x values for all the ordered pairs.Example the x value for the ordered pair (-3,-1) is -3.After you have found all the x values put them in order from least to greatest.I any x values are repeated then leave them out.Example if your x values are 0,1,1,2,3,3,4 then leave the extra 1 and 3 out and then you have 0,1,2,3,4.Once you have put the x values in order from least to greatest  and left out any extra repeated x values the you are done and you have your domain for the function.
