Ratios can be described in different ways, if you were given a fraction such as 2/4 then we would put in 3 ways like 2/4, 2:4, and 2 to 4. So basically in any rule with fractions or anything else like that you'd have to explain it in 3 ways like my example shows.

Hopefully this helped. :)

I need help please.....

Here, Function: h(t)= -16t² + 70t + 40

So, put the value of t, (time at which you want to calculate the height)

h(1) = -16(1)² + 70(1) + 40
h(1) = -16 + 110
h(1) = 94

Now, h(2) = -16(2)² + 70(2) + 40
h(2) = -64 + 180
h(2) = 116

h(3) = -16(3)² + 70(3) + 40
h(3) = -144 + 250
h(3) = 106

In short, Your height depends on time, and at each time it would be different, can be expressed by the coordinates on a Graph: (1, 94) (2, 116) (3, 106)

Hope this helps!
