In Exercises 15-18, find the measure of the exterior angle.​
valina [46]

Answer:

The measure of the exterior angle is 92 degrees

Step-by-step explanation:

Problem 16)

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

so

In this problem

(2x-2)\°=x\°+45\°

solve for x

2x-x=45+2

x=47\°

Find the measure of the exterior angle

(2x-2)\°=(2(47)-2)=92\°

A factory produces 6 motorcycles in 9 hours. How many hours will it take to produce 16 motorcycles at this rate ?
Shtirlitz [24]

Answer:

24 hours

Step-by-step explanation:

Let m represent motorcycles and h represent hours it takes to make the motorcycles

6m=9h

12m = 18h

9 \div6=1.5

1m = 1.5h

1.5 +1.5+1.5+1.5=

1.5+1.5=3.0

3.0+3.0=6.0

=6

18+6=24

=24h

Therefore it takes "24 hours" to create 16 motorcycles.

Hope this helps.

Compute i^1+i^2+i^3....i^99+i^100
fgiga [73]

Good morning ☕️

Answer:

<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ = 0</h3>

Step-by-step explanation:

Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰

S =  i¹ +  i² +  i³ + . . . + i⁹⁹  +  i¹⁰⁰

S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀

then, S is the sum of 100 consecutive terms of a geometric sequence (an)

where the first term a1 = i¹ = i  and the common ratio = i

FORMULA:______________________

S=(term1)*\frac{1-(common.ratio)^{number.of.terms}}{1-(common.ratio)}

_______________________________

then

S=i*\frac{1-i^{100} }{1-i}

or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1  (we know that i⁴ = 1)

Hence

S = 0
