Answer:
x-intercept (-14/9, 0), y-intercept (0, -14)
Step-by-step explanation:
0=-9x-14
9x=-14
x=-14/9
y=-9(0)-14
y=-14
X^2-5x-24=0
I don't know you use which way, i just tell you the easy way i think.
x^2-5x-24=0
24=2x2x2x3
So we can have those two numbers: 3, -8
The answer is (x+3)(x-8)
Ф =5π/6
The reference angle is the smallest angle that the terminal side of the angle makes with the x-axis.
Given that here π/2 < Ф < π, the angle is in the second quadrant.
In the second quadrant the signs are:
sine positive
cosine negative
tangent negative.
Furthermore, the reference angle is π - Ф = π - 5π/6 = π/6.
Then,
sin Ф = sin π/6 = 1/2
cos Ф = - cos π/6 = -√(3) / 2
tan Ф = - tan π/6 = -√(3) /3
I’m not sure, i’m sorry :(
