Water is being poured into a "Dixie cup" (a standard cup that is smaller at the bottom
than at the top). The height of the water in the cup is a function of the volume of
water in the cup. The graph of this function is
(a) increasing and concave up
(b) increasing and concave down
(c) a straight line with positive slope.

(c) a straight line with positive slope.

Step-by-step explanation:

Functions

We are required to find a function that relates the height of the water in a cup to the volume of water in the cup.

The cup has a shape of a cone open upwards. The volume of a cone of height h and radius r is

This function relates the height with the volume, to find the required function, let's solve for h

Rearranging

Being all the values positive, the height and the volume are linearly related with positive slope

(c) a straight line with positive slope.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

they go with it happens or they mite give a chance?
