The amount of oxygen in the flask through the intake tube illustrates proportions
The flask 99.35% will contain of oxygen after 5L have passed through the intake tube
<h3>How to calculate the percentage of oxygen?</h3>
To do this, we make use of the following representations
- P for the proportion of oxygen
- V for te volume of oxygen
- x for the proportion of oxygen in the flask after 5 L passed through
So. we have the following derivative
dP = dV - P * dV
Divide through by dV
dP/dV = 1 - P
Next, we set up the integral
Integrate both sides
Expand
-ln(|x - 1|) + ln(|0.04 - 1|) = 5
Evaluate the difference
-ln(|x - 1|) + ln(|-0.96|) = 5
Express as a fraction
ln(0.96/|x - 1|) = 5
Express both sides as exponents with a base of 2
e^ln(0.96/|x - 1|) = e^5
Solve for x
x = 1 - 0.96/e^5
Evaluate the difference
x = 0.9935
Express as percentage
x = 99.35%
Hence, the flask 99.35% will contain of oxygen after 5L have passed through the intake tube

Answer:
the markup is 1.26 (the amount added is .26)
1.26x (when x is the price Fred buys them for from the manufacturer)
1.26(40)
$50.40 is the retail price
50.4-40
$10.40 is the markup
Step-by-step explanation:
The 26% markup means that he is selling the flags 26% above the cost.
So, the cost would represent 100%, which is 1, and 26% of markup in decimal number is 0.26.
The price including the markup would be 1.26 as decimal or 126% as percentage.
The problem states that the cost is unknown, so we represent that with a variable x. The retail price would be 1.26x, which is 126% per flag.
Finally, if Fred paid $40 per flag, the actual retail price would be:
1.26($40)=$50.40.
With $10.40 of markup.
Answer:
y= 73 degrees
x=34 degrees
Step-by-step explanation:
180-107=73
y= 73 degrees
73+73= 146
180-146=34
x=34 degrees

Answer:
What is a polynomial?
- In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables
What is a rational function?
- In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.
Are all polynomials rational functions?
.A function that cannot be written in the form of a polynomial, so no they are not all functions.
