5 0

Answer:

y=x^{3} -2x^{2} -x+2

Step-by-step explanation:

You are given the roots 1, -1, and 2.

From there, you can combine all these factors into:

(x-1)(x+1)(x-2)

You know this because if you set these factors to 0, it will give you the roots 1, -1, and 2.

You can find the answer by multiplying all the factors and you get:

x^{3} -2x^{2} -x+2

Hope I helped :)

saw5 [17]

40-15=25 students not on student council

25/40 = .625 decimal

multiply by 100 to get percent

62.5% of students are not on student council

Estimating:

15 rounds to 20 and 40 rounds to 50

40% are in student council and that leaves roughly 60% not in student council.

In △ABC, m∠A=27 °, c=14 , and m∠B=25 °. Find a to the nearest tenth.
Gnesinka [82]

Answer:

a = 8.1

Step-by-step explanation:

Firstly, since we have a triangle, automatically, we have 3 interior angles

Mathematically the sum of these angles = 180

A + B + C = 180

27 + 25 + C = 180

52 + C = 180

C = 180-52

C = 128

We use the sine rule to find a

The sine rule posits that the ratio of a side to the sine of the angle facing that side is equal for all the sides of a triangle

Thus, mathematically according to the sine rule;

c/Sin C = a/Sin A

14/sin 128 = a/sin 27

a = 14sin27/sin 128 = 8.0657

which to the nearest tenth is 8.1
