Answer:

Step-by-step explanation:

Do a vertical line test.

First, put your pencil or ruler up against the screen.

Move it down the graph and if there are two points in one x point, it is not a function. For example, look at 0, 3 and 0, -2.5. They share the same x point.

Therefore, it is not a function.

Answer:

In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.

How do I find the median for a congruent triangle

Andrej [43]

The length of a median is equal to half the square root of the difference of twice the sum of the squares of the two sides of the triangle that include the vertex the mediam is drawn from and the square of the side of the triangle the median is drawn to.

triangle sides by a, b, c.

If a fourth plant produces 400 widgets in 60 days, which statement is true?

USPshnik [31]

The complete question in the attached figure

the statements are
1) It makes less than plant B
2) It makes the same as plant A
3) It makes more than plant C

we know that
<span>analyzing the graph

</span>plant A
for x=40 y=100
for x=50 y=200
that means
the production in 10 days is 100 widgets
then
the production in 60 days will be 6*100----> 600 widgets
so
plant A production > plant fourth production
plant fourth production < plant A production

plant B
for x=40 y=0
for x=60 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
so
plant B production < plant fourth production
plant fourth production > plant B production

plant C
for x=20 y=0
for x=40 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
plant C production < plant fourth production
or
plant fourth production > plant C production

therefore

the answer is
3) It makes more than plant C
