1:2 can equal 1/2. Hope this helps >^_^<
Answer:
Step-by-step explanation:
Given that When n is divided by 21, the remainder is an odd number.
i.e. 
where m is an integer and k a positive integer <21
When n is divided by 28, the remainder is 3
, where c is a positive integer
This can be written as
Since n is giving odd remainder when divided by 21,
we get r =3 as n is a multiple of 7 +3
<span>Ans : f(x)=xe^(-x^2/8)
differentiating by applying product rule,
f'(x)=x(e^(-x^2/8))((-2x)/8)+e^(-x^2/8)
f'(x)=e^(-x^2/8)(-x^2/4+1)
f'(x)=-1/4e^(-x^2/8)(x^2-4)
Now to find the absolute extrema of the function , that is continuous on a closed interval, we have to find the critical numbers that are in the interval and evaluate the function at the endpoints and at the critical numbers.
Now to find the critical numbers, solve for x for f'(x)=0.
-1/4e^(-x^2/8)(x^2-4)=0
x^2-4=0 , x=+-2
e^(-x^2/8)=0 ,</span>
Answer:
so if you subtract 14 from a number then multiply the difference by - you get -42
