Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation: 
where r is the radius
Plug in the given area 161 in.²
Divide both sides by π to isolate r²
Take the square root of both sides to isolate r
Therefore, the radius of the circle is approximately 7.16 in.
I hope this helps!
Answer:
The pressure exerted by gas number 3 is 159 mmHg
Step-by-step explanation:
To answer this question, the law to Use is Dalton’s law of partial pressure
Dalton’s law of partial pressure states that for a mixture of gases which do not mix, the total pressure exerted by such gases is equal to the sum of the individual pressure.
Now for the three gases, the total pressure Pt is equal to P1 + P2 + P3
Now we have Pt = 950 mmHg, P1 = 335 mmHg and P2 = 456 mmHg
P3 = Pt-P1-P2
Plugging the values above, we have ; 950-335-456 = 159 mmHg
The roots or zeros of a polynomial are the points it crosses the x-axis.
The roots of the polynomial in order from least to greatest are -5, 0 and 5
From the graph (see attachment), we have the following highlights
- <em>The graph cross the x-axis at x = -5</em>
- <em>The graph cross the x-axis at x = 0</em>
- <em>The graph cross the x-axis at x = 5</em>
The points at which the graph crosses the x-axis are the roots of the graph.
So, the roots are: -5, 5 and 5
