Plsssssssss help!!!!!!!!!!!!!!!!!
ss7ja [257]

Answer:

C) ∠LMO = 50°

Step-by-step explanation:

When you add the degrees of all the angles in a triangle, you get 180, so...

180 = 60 + 70 + x

180 - 60 - 70 = x

x = 50

Write each sequence as a function.
Fiesta28 [93]

Answer: f(n)=3^{n-1}

Step-by-step explanation:

Given Recursive formula : a_{n+1} = 3a_n,, a_1=1

Then,  a_2=a_{1+1} = 3a_1=3(1)=3

a_3=a_{2+1} = 3a_2=3(3)=9

a_4=a_{3+1} = 3a_3=3(9)=27

We can write it as : f(n)=3^{n-1}

such that

n      f(n)=3^{n-1}

1       f(1)=3^{1-1}=1

2       f(2)=3^{2-1}=3^1=3

3       f(3)=3^{3-1}=3^2=9

Hence, the required function: f(n)=3^{n-1}

A Ferris wheel rotates 9π/8 radians prior to making a stop. The total height of the Ferris wheel is 246 ft. How far around did t
WARRIOR [948]

Answer:

The ferris wheel travelled 434.717 ft.

Step-by-step explanation:

Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:

radius = height/2 = 246/2 = 123 ft

The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:

length = r*(angle in radians)

length = 123*(9pi/8)

length = 434.717 ft

The ferris wheel travelled 434.717 ft.
