Determine the sum of the exterior angles in a convex 50-gon. (G.10)(1 point)

Answers

Answer:

The sum of the exterior angles in a convex 50-gon polygon is 360°⇒ A

Step-by-step explanation:

The formula of the sum of the interior angles of any polygon is ∑ = (n - 2) × 180°, where, n is the number of the sides or the angles of the polygon
The sum of the measures of the interior angle and the exterior angle at a vertex of the polygon is 180°
The sum of the exterior angles of any polygon (n-gon) is 360°

In the question

∵ The polygon has 50 sides

→ By using the 3rd rule above

∵ The sum of the exterior angles of any polygon (n-gon) is 360°

∴ The sum of the exterior angles in a convex 50-gon polygon is 360°

A company is planning to make a new kind of radio. The cost to produce x radios is C(x) = 80,000 + 10x. Meanwhile, the revenue earned by selling x radios is given by R(x) = 18x. If R < C, the company loses money. At what level of production does this happen?

Answers

$C(x) = 80,000 + 10x\ \ \ \wedge\ \ \ R(x) = 18x\n\nR < C\ \ \ \Leftrightarrow\ \ \ \ 18x<80,000+10x\n \n8x<80,000\ /:8\n \nx<10,000\n \nAns.\ The\ company\ loses\ money\ at\ level\ of\ production\ 10,000\ radios.$

What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8? an = 2(−8)n − 1; all integers where n ≥ 1 an = 2(−8)n − 1; all integers where n ≥ 0 an = 2(−4)n − 1; all integers where n ≥ 0 an = 2(−4)n − 1; all integers where n ≥ 1

Answers

Hello,

The question is
"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"

It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4

U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.
