Answer:
Step-by-step explanation:
The formula of a volume of a sphere:
R - radius
We have R = 3 ?. Substitute
If the radius is 30, then the volume is:
If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:
Answer:
(A)If x represents the number of songs she downloads then it is a variable because of the AMOUNT of songs she downloads.
Step-by-step explanation:
For example if we had f(x)=2 the equation would be c=4.99+.75(2)
.75*2=1.50+4.99=
(6.49 = c) cost per month if she downloads 2 songs
4+4=8
right???????????????????????
Answer:
(For the first two questions I do believe that you will need a protractor to calculate the angles.)
15) 
measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)
The first image attached shows where the angle should be located.
16) 
is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))
17) 350° is 
or 6.11 (the answer depends on the format the professor wants.)
18) 240° is 
radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)
Answer:
The value of f[ g(x) ] = 7x + 27
Step-by-step explanation:
It is given that, f( x ) = 7x + 13 and g( x ) = x + 2
<u>To find the value of f(g(x))</u>
g(x) = x + 2 and 7x + 13 (given)
Let g(x) = x + 2
f [ g(x) ] = 7(x + 2) + 13 [ substitute the value of g(x) in f(x) ]
= 7x + 14 + 13
= 7x + 27
Therefore the value of f[ g(x) ] = 7x + 27
