Mathematics

Although I am not clear as to whether the radius is r—1 or otherwise, but if i work with the values i see then:

Volume — T. S. A.

= πr²h — (2πr²+2πrh)

So after the simplification, I substitute the values given,

r= r—1 and h=h—1

And the answer is...

π(r—1)(rh—3r—3h+5)!

3. Which relation is a function?
Pani-rosa [81]

Answer:

B

Step-by-step explanation:

Recall that functions are defined only if for each value in the domain produces one and only one value in the range.

If we view the relations in the questions as x-y coordinates, this means that for every x-value, you can only have one y-value

Lets evaluate the options:

A) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)

C) we can see that for x = 3, this gives 2 possible values for y i.e (3,-8) and (3,8) (hence this is not a function)

D) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)

the only choice where this doesn't occur is choice B

tiny-mole [99]
If Rodger is working 20hs and gets $9 per hour you would do this:

1- $9 * 20 = $ 180 per hour
2- check work = $ 180/ 9 = 20hs
3- now that you know your answer is $180 you would say this: Rodger will earn a total of $180 if he works 20hs and gets payed $9 an hour
