Answer:
The quadrilaterals which have opposite angles congruent are parallelograms.
Hope it will help :)
Decay expression is stated as follows:
N(t) = N(o)e^(-0.693t/t1/2)
N(t) = Quantity remaining after time, t; N(o) = Initial quantity, t = time, t1/2 = Half life
Therefore,
N(6.55) = 2*e^(-0.693*6.55/5.2) = 0.835 g
Be specific. We need more details.
Answer:
20%
0.5
Step-by-step explanation:
There are 20 margins, so you have to count how many are 6.0 or higher. There are 4 margins that fit this so you divide the 4 margins by 20, then multiply the quotient by 100. That's how you get 20%.
The most common time was 0.5.
Answer:
(a) Circle Q is 9.4 units to the center of circle P
(b) Circle Q has a smaller radius
Step-by-step explanation:
Given
Solving (a): The distance between both
The equation of a circle is:
Where
P and Q can be rewritten as:
So, for P:
For Q:
The distance between them is:
Where:
---
---
So:
Solving (b): The radius;
In (a), we have:
--- circle P
--- circle Q
By comparison
<em>Hence, circle Q has a smaller radius</em>
