nico and fleur are each designing a fictional bike for their business science class. nico determines, through research, that the marginal of producing a bike is

cz(x)-0.0005x2+0.07x+50, for which c1(x) is the cost for manufacturing her bikes could be modeled by cz(x)=25x+62.5. assuming each student's fictional company starts "manufacturing" bikes at the same time answer the following questions.

-what is the domain and range of nico's functions? explain what the domain and range represent. do all of the values make sense in this situation? why or why not?

-what are the x- and y- intercepts of nico's function? explain what each intercept represents.

-is the linear function you created positive or negative? explain.

-what are the solutions or solution to the system of equations created? explain what it or they represent.

-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

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

inverse property is the answer
