F(1) = (1)^3 + 2(1)^2 - 5(1) - 6 = 1 + 2 - 5 - 6 = -8; x = 1 is not a solution to the polynomial.
f(-1) = (-1)^3 + 2(-1)^2 - 5(-1) - 6 = -1 + 2 + 5 - 6 = 0; x = -1 is a solution to polynomial.
From the options, a or c has x = -1, both has x = , so lets check for x = 3
f(3) = (3)^3 + 2(3)^2 - 5(3) - 6 = 27 + 18 - 15 - 6 = 24; x = 3 is not a solution to the polynomial.
Therefore the solutions to the polynomial are x = -3, x = -1, x = 2
Answer:
the best estimate is 361.4 dude
Step-by-step explanation:
Answer:
Step-by-step explanation:
The probability that a person answered incorrectly is 4/5
P(1st answered incorrectly AND 2nd answered incorrectly AND
3rd answered incorrectly AND 4th answered incorrectly AND
5th answered incorrectly AND 6th answered incorrectly AND
7th answered incorrectly AND 8th answered incorrectly)
Since "AND" mean to multiply, the probability that none of the 8 guessed correctly is
4/5×4/5×4/5×4/5×4/5×4/5×4/5×4/5
=(4/5)^8
=0.16777216
Answer:
The angle is 35
Step-by-step explanation:
The angles are vertical angles, so they are equal
3x-4 = 2x+9
Subtract 2x from each side
3x-2x-4 = 2x+9-2x
x-4 = 9
Add 4 to each side
x-4+4 = 9+4
x=13
But it asked for the measure of the angle
2x+9
2(13)+9
26+9
35
