Answer: 0.73 + πk, 0.28 + πk
<u>Explanation:</u>
cos (2x - 1) = 0.9
cos⁻¹[cos (2x - 1)] = cos⁻¹ 0.9
2x - 1 = +/- 0.45
2x = +/- 0.45 + 1
x = 
x = 
, x = 
x = 0.73, 0.28
For ALL Solutions:
x = 0.73 + πk and x = 0.28 + πk
Answer:
$27000
Step-by-step explanation:
Using the given formula :
I = P × R ×T
I = 90000 × 10/100 × 3
I = $27000
We know that:
perimeter = (2 x width) + (2 x length)
Plugging in what we know to this equation:
40 = (2 x 8) + (2 x length)
40 = 16 <span>+ (2 x length)
</span>24 = <span>2 x length
</span>12 = length
The length of the room is 12 feet
