Answer:
2(x + 3)(x + 1)(x - 4)
or 2x^3 - 26x - 24.
Step-by-step explanation:
We can write the polynomial if factor form:
P(x) = a(x + 3)(x + 1)(x - 4) where a is some constant.
Now, since f(-2) = 12 we can write :
12 = a(-2 + 3)(-2 + 1)(-2-4)
12 = 6a
a = 2.
So the polynomial is
2(x + 3)(x + 1)(x - 4).
Expanded that is
2(x + 3)(x^2 - 3x - 4)
= 2(x^3 - 3x^2 - 4x + 3x^2 - 9x - 12)
= 2x^3 - 26x - 24.
Slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
we are given the points (-2,7) and (x,2)
slope is -1/3
so
(x,y)
(-2,7) and (x,2)
x1=-2
y1=7
x2=x
y2=2
slope=(2-7)/(x-(-2))=-1/3
slope=(-5)/(x+2)=-1/3
multiply both sides by (-3)(x+2) (basically cross multiply)
15=x+2
minus 2 both sides
13=x
x=13
the value of x is 13

Answer:
140°
Step-by-step explanation:
The long arc intercepted by angle c is 360° -80° = 280°. The measure of inscribed angle c is half the measure of the arc it intercepts.
c = 280°/2 = 140°
