Annette [7]

Answer:

(5 + 3i)(5 − 3i) = 34

Step-by-step explanation:

The multiplication of two identical binomials who have different symbol, can be solved using the factoring case of a difference of squares:

(a-b).(a+b)=a^{2}-b^{2}

So, in this case:

(5+3i).(5-3i) = 5^{2}-(3i)^{2}

=25-9i^{2}

Remember that i=\sqrt{-1}

So: i^{2}=-1

We replace on the polynomial:

=25-9.(-1) = 25+9=34

Let f be a differentiable function on (-0o,00) such that f(-x)= f(x) for all x in (, o). Compute the value of f'(0). Justify you
snow_lady [41]

Answer:

f'(0)=0

Step-by-step explanation:

Applying the chain rule

\frac{d}{dx} (f(-x))=-\frac{df}{dx}

Then it becomes

\frac{df}{dx} =-\frac{df}{dx}

In x=0

\frac{d[tex]f'(0)=-f'(0)\\f'(0)+f'(0)=0\\2f'(0)=0\\f}{dx} =-\frac{df}{dx}[/tex]

Then

f'(0)=0
