Area of the rooms:
Room I = 15.9 * 8.6 = 136.74
Room II = 11.9 * 6.3 = 74.97
Hence, the total area is: 211.71 square foot.

211.71 square foot * 12 each square feet = <span>$</span>2540.52
Answer:
Option D is correct.
Explicit formula for the geometric sequence is, 
Step-by-step explanation:
Geometric sequence states that a sequence of numbers in which the ratio between consecutive terms is constant,
we can write a formula for the nth geometric sequence in the form of:
.....[1] where
is the first term and r is the common ratio between successive term.
Given the sequence: 64, 32, 16 , 8......
Here, first term (
) = 64.
Common ratio(r) = 0.5
Since,

,
......
Substitute the value of a and r in [1] we get;

therefore, the explicit formula for the geometric sequence is, 
Answer:
(21, 28)
Step-by-step explanation:
Multiply coordinates by 7.
The slope is 2 i’m pretty sure
You use desmos. It’s helpful
Good luck !
