For the first one, I think it's either B or C but I'm not sure. The other ones I don't know. Please help and show work. Thank you!

If  (x-7) is a factor, then when you calculate f(7)     '7 ' would be sustituted in for x     then (x-7 )   would be  (7-7)  and the function would = 0

Answer B

First one....if   ( x - 7)   is a factor, then  7  is a root....therefore....f(7)  =  0

 

For the second....just substitute  3 into the polynomial and evaluate.....the answer will =  p(3) = the remainder

 

Last one

 

Volume of the hemisphere  =   (2/3)pi (radius)^3

The radius  = 5 inches

So.....the volume is      (2/3)pi (5)^3  =  (250/3)pi  in^2  ≈  262  in^3

 

So

 

Volume of hemisphere / 14.44    =   262 / 14.44 ≈   18 cups

Thank you so much for your help. I thought I was supposed to plug 3 into the equation but I was confused with the remainder. Thanks!
