The number of windows on each floor form an arithmetic sequence; 124 windows on the first floor, 116 windows on the second floor

zubka84 [21]

Answer:

Formula is 132 - 8n, and there are 52 windows on 10th floor.

Step-by-step explanation:

difference = 116-124 = -8 ( 8 less windows for every floor you go up)

the first fllor has 124 windows

Formula:

$a_{1} = 124$

$a_{n} = 124 + (-8)(n - 1)$ = 132 - 8n

10th Floor:

$a_{10} = 124 + (-8)(10 - 1) = 124 + (-8)(9) = 124 - 72 = 52 windows$

Help !!!!!!!!!!!!!!!!

umka2103 [35]

Answer:

13) 8.6

Step-by-step explanation:

To find the side length, use a trig function to solve for x.

You have the adjacent side and hypotenuse to the angle. Use the cosine function since its ratio is adjacent over hypotenuse.

This means Cos 52 = x / 14. Solve for x.

Cos 52 = x / 14

14* Cos 52 = x

8.6 = x
