Answer 1

`a = 8.5t`

`y = 32.55`

Explanation:

Solving (9): The equation of the table

We start by calculating the slope (m)

`m = (a_2 - a_1)/(t_2 - t_1)`

Where:

`(t_1,a_1) = (15,127.5)`

`(t_2,a_2) = (16.5,140.25)`

`m = (140.25 - 127.5)/(16.5 - 15)`

`m = (12.75)/(1.5)`

`m = 8.5`

The equation is then calculated using:

`a = m(t - t_2) + a_2`

So, we have:

`a = 8.5(t - 16.5) + 140.25`

Open bracket

`a = 8.5t - 140.25 + 140.25`

`a = 8.5t`

Solving (10):

`4.8y = 156.24`

Find x

Divide both sides by 4.8

`y = 32.55`
