Atrainer takes a survey of all the athletes in a school about their height, rounded to the nearest inch, and their grade level. the trainer relates their grade levels to their heights. is this a function?

No.

Step-by-step explanation:

We have been given that a trainer takes a survey of all the athletes in a school about their height, rounded to the nearest inch, and their grade level. The trainer relates their grade levels to their heights.

Since we know that a function gives exactly one output for a given input.

Let us see that this relationship is a function or not.

We can see that this is not a function because there can be students from different grades with same height. So we can see that one input produces multiple outputs, therefore, this is not a function.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

i need points
