Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((<span>|8 + 3| -1) - (</span><span>|-6 + 3| -1))/(8 + 6) = ((</span><span>|11| -1) - (</span><span>|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7</span>
The volume of a gas in a container varies inversely with the pressure on the gas. If a gas has a volume of <span>250 </span>cubic inches under a pressure of<span>
</span><span>4 </span>pounds per square inch, what will be its volume if the pressure is increased to 20 pounds per square inch? (Round off your answer to the nearest cubic inch.)
Answer:
Step-by-step explanation:
<u>Find the volume of cylinder:</u>
<u>Convert the dimensions into yards:</u>
- d = 24 inches = 24/36 yards = 2/3 yards ⇒ r = 1/2d = 1/2*2/3 = 1/3 yards
- h = 6 feet = 6/3 yards = 2 yards
<u>Find the volume by substituting the values:</u>
- V = 3.14*(1/3)²*2 = 0.69777 ≈ 0.7 yd³
Correct choice is C
He would use 3 cages for the canaries (6 in each) and 6 cages for the parakeets (7 in each)
