In this problem, volume is computed:
volume = ∫(flow rate)·dt
.. = ∫[0, t] (3/10)*sin(2πt/7)·dt
= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1)
= (-21 / (20 π))*(cos (2 π t /7) - 1)
Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t
Answer:b.....
Step-by-step explanation:
because we learned about this
Given:
Total cheese = 12 pound
Cheese in each package = 
pounds
To find:
The number of cheese packages.
Solution:
We need to divide the total amount of cheese by quantity of cheese in each package to find the the number of cheese packages.
Therefore, there are 24 number of cheese packages.
Answer:
x = -5, 7
Step-by-step explanation:
Step 1: Write equation
x² - 2x - 35 = 0
Step 2: Solve for <em>x</em>
<u>Factor:</u> (x - 7)(x + 5) = 0
<u>Find roots:</u> x = -5, 7
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
(-5)² - 2(-5) - 35 = 0
25 + 10 - 35 = 0
35 - 35 = 0
0 = 0
7² - 2(7) - 35 = 0
49 - 14 - 35 = 0
35 - 35 = 0
0 = 0
