Sigma(i = 7 to 16, 2i-12) = 2*sigma(i = 7 to 16, i) -120
= 2*115-120 = 110
Answer:
If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
Consider the sum of the measures of the exterior angles for an n -gon.
N=180n−180(n−2)
Distribute 180 .
N=180n−180n+360 =360.
Step-by-step explanation:
Answer:
The correct answer is C) (x - 1)(x + 30)
Step-by-step explanation:
To find this, we need to find factors of the last number (-30) that add up to the middle number (29). In order to do this, list out all of the factors of -30.
-1 and 30
1 and -30
2 and -15
-2 and 15
3 and -10
-3 and 10
Since -1 and 30 satisfy both of the parameters, we put them into their own parenthesis along with x.
(x - 1)(x + 30)
Answer:
The answer is $0.36
Step-by-step explanation:
Answer:
V = 235.5
Step-by-step explanation:
V=π r^2 h
V = pi 5^2 3
V = pi 25 3
V = 3.14 * 75
V = 235.5
