How much work, in joules, is done when the pressure is suddenly released from 4.56 atm to 1.23 atm on 45.4 g of O2 at 45 degree C?
How much work, in joules, is done when the pressure is suddenly released from 4.56 atm to 1.23 atm on 45.4 g of O2 at 45 degree C? Apparently the answer is -2.73*10^3 Joules, but I'm not sure how to get that. Could someone please explain it to me. Thank you.

1 AnswerMathematics7 years agoSqueeze Theorem piecewise defined function problem?
f is the piecewise defined function:f(x) =
1 + x^2 if x is irrational
1 + 4x^4 if x is rational.
Use the Squeeze Theorem to find limx→0 f(x).
Note: Enter the missing values in their decimal form.
Pick the choices and enter a value where the question marks are for Part A and B to complete the solution
Solution: Clearly, for all real numbers x, f(x) ≥ 1.
Next, we note that for a real number x,
x^2- 4x^4= x^2(1 − 4x^2) ≥ 0
Part A: Pick one of the choices and fill in the question marks.
if and only if
Choices:
1) xˆ2
2) 4xˆ2-1
3) 1-4xˆ2.
≥ 0. This means that x^2≥ 4x^4
if and only if x ∈ [?,?]
Part B:
Particularly, we get that for all
Choices:
1)rational
2) irrational.
numbers x in [ ?,? ] we have
f(x) = 1 + 4x^4≤ 1 + x^2
Therefore, for all x ∈ [? ,? ], we have that
1 ≤ f(x) ≤ 1 + x^2
.

3 AnswersMathematics10 years agoMath interest rate matching, ten points for correct combination?
Select the rate that is defined by each statement. (Match the letters to the numbers)
A compound rate
B nominal rate
C simple interest
D compound interest
E annual rate
F effective rate of interest
G none of the above
1. The interest calculated only on a principal over time.
2. The interest rate stated per compounding period.
3. The interest that is earned continuously and added to
the principal and then collects interest itself continuously.
4 The simple rate of interest that yields the same future
amount after one year as the nominal rate compounded m
times.
5. The interest that is earned and added to the principal
and then collects interest itself.
1 AnswerMathematics1 decade agoCompounding Interest Ten points for correct answers?
As part of a one payment scholarship, you can choose between option A: receive $5000 now (which means you can put it into your savings account and earn interest), and option B: wait two years and receive an additional $277 (which means you are not collecting interest). Assume that money can be invested at 3% compounded semi-annually.
Calculate the rate of interest per compounding period:
Calculate the future amount under option A:
Calculate the future amount under option B:
Why one should you chose?

at the same time the following morning. The total amount of the drug in her body t
days after the first dosage was taken is given by
A(t)=100e^(-1.4t) if 0<=t<1 or 100(1+e^(1.4)e^(-1.4) if t>=1

1 AnswerMathematics1 decade agoBusiness Calculus Question, 10 points for correct answer.?
A manufacturer has found that when n employees are working, the number of unites of product produced per day is q = 10*sqrt(n^2+3600) - 6000. The demand equation for the product is 9q +p^2-7200 = 0, where p is the selling price in dollars when the demand for the product is q units per day.
a) Determine the manufacturers marginal revenue MR when n = 80, i.e. the relative rate of change of revenue with respect to the number of units produced per day.
b) Determine the manufacturers revenue product MRP when n = 80, i.e. the relative rate of change of revenue with respect to the number of employees when n = 80
c) Suppose it would cost the manufacturer $400 more per day to hire an additional employee. Would you advise the manufacture to hire the 81st employee? Why?
