1.1.3 quiz precalculus

A,C,D

Step-by-step explanation:

a linear equation is in the form of y=mx+b

in this case slope m is unidentified and there is no y intercept, and x=3 vertical line.

A)  the equation is x=3 ( right answer)

x=3 is not a function in the normal sense

however in this case we might say that the relation ship is 3

so the Domain and the range  equal to 3

there are no short passages to look at

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
