Since the graph of the given functions is a straight line, the graph belongs to a linear function, as all linear functions have their graphs as a straight line. For a non-linear function the graph is not a straight line. 

For a relation (non-function), the line passes through same value of x for more than one points. 

Hence the correct answer is "Linear Function"

Show that the maximum rate of change, with respect to radius, of the volume of a deflating balloon is four times the sphere's in
dmitriy555 [2]

Step-by-step explanation:

Let's say R is the initial radius of the sphere, and r is the radius at time t.

The volume of the sphere at time t is:

V = 4/3 π r³

Taking derivative with respect to radius:

dV/dr = 4π r²

This is a maximum when r is a maximum, which is when r = R.

(dV/dr)max = 4π R²

This is 4 times the sphere's initial great circle area, but not the great circle circumference.  The problem statement contains an error.

Plums are $3.25 for 2 pounds, i need 4 pounds. how much will it cost
olasank [31]
<u />\frac{3.25}{2lbs} = \frac{x}{4lbs}  \\  \frac{3.25}{2} *  \frac{2}{2} = \frac{x}{4}  \\  \frac{3.25 * 2}{2*2} = \frac{x}{4}  \\ 3.25*2 = x \\ x = 6.50
It will cost $6.50 for four pounds of plums.

Hope this helps!

Ron Finley is a gardener who decided a few years ago to plant several gardens in South Central Los Angeles. He wants his next ga
yaroslaw [1]

Well, we can be sure that whatever the width is, we can call it ' W '. Then, from information in the question, the length of the garden is ' 3W '.

Now, the perimeter of a rectangle is (length + width + length + width). Using the fancy algebra labels I just gave them, that's (3W + W + 3W + W). And now I can go through that, add up all the Ws, and get a total of 8W for the perimeter.

But he question tells us that the perimeter is 24 yards, so 8W = 24 yds.

Divide each side of that equation by 8, and we discover that W = 3 yds. And if THAT's true, then 3W = 9 yds. Bada bing ! We have the dimensions of the garden.

It's 3 yards wide and 9 yards long.
