1 hour = 3600 seconds.
Multiply total hours by 3600.
2.26 hours x 3600 = 8136 seconds.
The answer is D.
Answer:
Step-by-step explanation:
Perimeter = 48 feet
2*(length + width) = 48
2*(9 + width ) = 48
Divide both sides by 2.
9 + width = 48/2
9+width = 24
Subtract 9 from both sides.
9+width - 9 = 24 - 9
Width = 15 feet
Answer:
$9.40
Step-by-step explanation:
21.15/9=2.35 - This is the cost per pane
2.35*4=9.4 - This is the cost for 4 panes
Answer:
- f⁻¹(x) = (x + 1) / (x - 2)
- f⁻¹(1 ) = - 2
Step-by-step explanation:
<u>Given function:</u>
- f(x) = (2x + 1) / (x - 1)
<u>Find its inverse, substitute x with y and f(x) with x, solve for y:</u>
- x = (2y + 1) / (y - 1)
- x(y - 1) = 2y + 1
- xy - x = 2y + 1
- xy - 2y = x + 1
- y(x - 2) = x + 1
- y = (x + 1) / (x - 2)
<u>Substitute y with f⁻¹(x):</u>
- f⁻¹(x) = (x + 1) / (x - 2)
<u>Find f⁻¹(1 ):</u>
- f⁻¹(1 ) = ( 1 + 1) / (1 - 2) = 2 / - 1 = - 2
