Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
So in this case, the center is (2, -3) and the radius is 4/3.
Step-by-step explanation:
To subtract, you must first:
Find like denominators.
- Note: What you do to the denominator, you must do to the numerator.
- If there is an equal sign, and there are fractions on both side, what you do to one side, you do to the other.
Simplify:
-----------------------------------------------------------------------------------------
Take for example, a question such as:
7 3/10 - 9/20
First, change the mixed fraction into improper fraction:
7 = (7/1) * (10/10) = 70/10 + 3/10 = 73/10
Find common denominators. Remember that what you do to the denominator, you do to the numerator. Multiply 2 to both numerator and denominator:
(73/10)(2/2) = (146/20)
Simplify. Combine like terms
146/20 - 9/20 = 137/20
Simplify.
137/20 = 6 17/20
6 17/20 would be your answer for the example question.

The new pressure is 2 Kpa
<em><u>Solution:</u></em>
At constant temperature, the pressure of a sample of gas is inversely proportional to its volume
Therefore,
Let "p" be the pressure of sample gas
Let "v" be the volume
Then we get,
Where, "k" is the constant of proportionality
<em><u>I have some oxygen in a 2.28 liter container with a pressure of 5 kPa</u></em>
Substitute v = 2.28 and p = 5 in eqn 1
<em><u>I move all of it to a 5.7 liter container at the same temperature</u></em>
Substitute k = 11.4 and v = 5.7 in eqn 1
Thus new pressure is 2 kPa
