Answer:
he sum of the angles in all these triangles will be n x 180 degrees. The sum of the angles around the interior point is clearly 360 degrees, so the sum of the polygon’s angles will be (180n)-360 = (n-2) x 180 degrees.Here we have (n-2) x 180 = 2160, so n-2 = 12. So the polygon has 14 sides. 606 views
Step-by-step explanation:
x = unknown number (that is a solution/makes the inequality true)
When the inequality sign is </> (less than/greater than), the dot is an open circle.
When the inequality sign is ≤/≥ (less than or equal to/greater than or equal to), the dot is a closed circle.
14.) The line has an open circle on -8, and a closed circle on 11.
-8 < x ≤ 11 [x is any number greater than -8 and less than or equal to 11]
15.) The line has a closed circle on -14 and 5.
-14 ≤ x ≤ 5 [x is any number greater than or equal to -14 and less than or equal to 5]
A graph shows the function can be factored as
f(x) = (x -1)((x-8)² +1)
There is one real root and there are two complex roots. The latter can be found from the vertex form factor:
(x - 8)² + 1 = 0
(x - 8)² = -1
x - 8 = ±√(-1) = ±i
x = 8 ± i
The zeros of the function are {1, 8-i, 8+i}.
