Answer:
A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers. We have a top number, the numerator, and a bottom number, the denominator. For example, 1/2 is a fraction.
Step-by-step explanation:
Answer:the domain is every “x” coordinate and the range is the “y” coordinate
Step-by-step explanation:
If you have to tell whether it’s a function or not, all of the x values in the domain will be different for a function, and 2 or more of the same x value won’t be a function
Answer:
791.28 in^2
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The diameter is 12 so the radius is 1/2 d = 1/2(12) =6
V = 3.14 (6)^2 * 7
791.28 in^2
First find equation
center is (h,k) then
(x-h)^2+(y-k)^2=r^2
given
(7,0) is center
(x-7)^2+y^2=r^2
also given (2,0)
(2-7)^2+0^2=r^2
(-5)^2=r^2
25=r^2
(x-7)^2+y^2=25 is equation
take derivitive of both sides, implicit differntiaton
2(x-7)+2y dy/dx=0
2(x-7)=-2y dy/dx
(7-x)/y=dy/dx
at (2,0)
(7-2)/0
undefined
that means the line is x=something
(2,0)
the equation is x=2
