Answer:

question 16:y=3 question 17:B, or -3x^2-2x+1

Step-by-step explanation:

For question 16, all you have to do is graph it. sorry if i am a bit vague here, but trust me, it is y=3

For question 17, you have to look at the first number, or a, and if it is negative, it opens down, and if it is positive, it opens up.

common ratio is -3

geometric sequence

an = a1 * r^(n-1)

a8 = -2*-3^(8-1)

Find the value of x.

koban [17]

We have the similar triangles. Therefore the lengths of the sides are in proportion:

$\dfrac{x}{22}=\dfrac{42}{11+22}\\\\\dfrac{x}{22}=\dfrac{42}{33}\qquad\text{cross multiply}\\\\33x=(22)(42)\qquad\text{divide both sides by 33}\\\\x=\dfrac{(22\!\!\!\!\!\diagup^2)(42)}{33\!\!\!\!\!\diagup_3}\\\\x=\dfrac{(2)(42\!\!\!\!\!\diagup^{14})}{\not3_1}\\\\x=(2)(14)\\\\\boxed{x=28}$

Its decreased by 200 in the 4 years from 1994 to 1998 That is 50 less per year
In 1990 the population would have been 2500
So the required formula is

P = -50t + 2500 ( or you could write it as P = 2500 - 50t
