Y = -3(2) + 11
y = -6 + 11
y = 5
Answer is a) y = -3x + 11 , when x is 2 y is 5
For this case we have the following multiplication:

We can rewrite this operation to facilitate the calculation.
We have then:

From here, we apply the distributive property.
We have then:

Rewriting we have:

Finally adding all the numbers we have:

Answer:
The value of 6 * 298 is 1788 and the calculations can be provided as follows:

The equation for height as a function of time can be written as
.. h(t) = -16t^2 +110t +2
.. = -16(t^2 -55/8t) +2
.. = -16(t^2 -55/8t +(55/16)^2) +2 +55^2/16 . . . . . complete the square
.. = -16(t -55/16)^2 +191 1/16 . . . . . . . . . . . . . . . . . . vertex form
The maximum height the ball will reach is 191 1/16 feet.
