Simplify both sides of the equation and isolate the variable!
The answer would be 3.6
The periodicity of function is 
<em><u>Solution:</u></em>
Given that we have to find the period of function
<em><u>Given function is:</u></em>
<em><u>Use the below formula:</u></em>
Thus,
Now find the periodicity of cos(x)
We know that,
periodicity of cos(x) = 
Therefore,
Thus the periodicity of function is
No is your answer
Assuming that b ≠ a, the answers will not be the same.
For example, (remembering that b ≠ a) let us assume that b = 10, a = 5
10 - 5 = 5
5 - 10 = -5
5 ≠ -5
So the commutative property of subtraction does not work unless in certain cases, in which a = b.
hope this helps
Answer:
Step-by-step explanation:
Lenght should be the greater here. I am considering your question however.
Let length side is 'x'.
The width side is 'x +13'
Perimeter of a rectangle : 2 ×( length + width)
given that perimeter is 82
2 × ( x + x + 13) = 82
2 × ( 2x + 13) =82
4x + 26 = 82
2x = 56
x = 28 cm
length is 28
width is 41
