Is this model a function?

Mathematics
1 answer:
Wewaii [24]2 years ago
5 0

Answer:

Yes, that model is a function.

Step-by-step explanation:

A technical definition of a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

And the model shows that each domain ( x ) only goes to one codomain ( y )  which is what a function is.

Evaluate 4<br> M-n if m= -7 and n = 2.
gregori [183]

Answer:

-30

Step-by-step explanation:

I'm assuming the equation is 4m-n. If it is not please tell me.

If we know the values of m and n, we can just substitute inside the expression.

4(-7) - 2\\\\-28 - 2\\\\-30

Hope this helped!

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=72t-16t^2. What is the
irakobra [83]

Answer:

The maximum height that the ball will reach is 81 ft

Step-by-step explanation:

Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.

For an equation of the form

at ^ 2 + bt + c

So

the t coordinate of the vertice is:

t =-\frac{b}{2a}

In this case the equation is:

h(t)=72t-16t^2

So

a=-16\\b=72\\c=0

Therefore

t =-\frac{72}{2(-16)}

t=2.25\ s

Finally the maximum height that the ball will reach is

h(2.25)=72(2.25)-16(2.25)^2

h=81\ ft
