What is $8.99 rounded to the nearest cent

$9.00 would be your answer

Tip: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up and if the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

$9, round up the decimal!

third choice.

step-by-step explanation:

this a parabola is opened up since the directrix is under the focus and the directrix is horizontal.

this means the square part will be on the x:

the vertex is (h,k).

we already determined p was positive because it is faced up.

|p| also gives us the distance between the focus and the vertex or the distance between the vertex and the directrix.

this means 2|p| gives us the distance between the directrix and the focus.

the distance between the directrix y=-1 and the focus   (0,3) is )=4.

so 2|p|=4.

divide both sides by 2:

|p|=2

p=2 or p=-2

p=2 means the parabola is faced up.

p=-2 means the parabola is faced down.

we already determine p is positive so p=2.

  so we have this so far:

now the vertex lays halfway between the directrix y=-1 and the focus (0,3), so the vertex is .

plug in (h,k) as (0,1) to give us:

solve for y.

distribute:

add 8 on both sides:

divide both sides by 8:

simplify both sides:
