100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.
Assoli18 [71]

The factors of the equation x^2-3x-18 are (x-6)(x+3)

Step-by-step explanation:

We need to factor the quadratic trinomial. x^2-3x-18

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)

So, the factors of the equation x^2-3x-18 are (x-6)(x+3)

A 15° sector in a circle has an area of 11.9 m2. What is the area of the circle?
DaniilM [7]
<span>A 15° sector in a circle has an area of 11.9 m2. What is the area of the circle?
The area of the circle will be found as follows:
the fraction of the sector=15/360=1/24
the area of the circle will be:
area=(fraction of the circle)/(fraction of the sector)*(area of the sector)
=1/(1/24)</span>×11.9
=285.6 m²

Which one of these is an linear function , stuck between the two ?
NeTakaya

Answer:

C

Step-by-step explanation:

B would be classified as an absolute value function.

Even though C looks like it is just a horizontal line, it is continuous in all directions and does not curve or slant like letter B. Letter B would also have a different slope.

Remember that linear functions are also not vertical lines.
