Question

Which ordered pair cannot be a solution of h(t)=-16^2+80t If h is the height of a ball above ground after t seconds?

Answer 1

Answer:

NON of them can be a solution.

Step-by-step explanation:

When I plugged them in to the equation they all came out false.

Answer 2

Answer:

It seems that this question would make more sense if it were: Which ordered pair can be a solution of $h(t)=-16^2+80t$

All alternatives but B) cannot be a solution for the function.

Step-by-step explanation:

Here we have $t=x$

So, we may write the funtion as: $h(x)=-16^2+80x$

$h(x)=y$

Let's test all the points:

A)$(1, 64)$

$h(1)=-16^2+80(1)\\h(1)=-256+80\\h(1)=-176$

B)$(2, 96)$

$h(2)=-16^2+80(2)\\h(2)=-256+160\\h(2)=96$

C) $(-4, 256)$

$h(-4)=-16^2+80(-4)\\h(-4)=-256-320\\h(-4)=-576$

D)$(5, 0)$

$h(5)=-16^2+80(5)\\h(5)=144$
