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

$f'(0)=0$

Lines y and z are parallel.

Mrac [35]

Answer:

28 degrees

Step-by-step explanation:

step 1

Find the measure of angle 1

$m\angle 1+65^o=180^o$ ----> by supplementary angles

$m\angle 1=180^o-65^o=115^o$

step 2

Find the value of x

$(10x+5)^o=m\angle 1$ ----> by corresponding angles

substitute

$(10x+5)^o=115^o$

$10x=110\\x=11$

step 3

Find the measure of angle 2

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle 1+m\angle 2+(4x-7)^o=180^o$

substitute

$115^o+m\angle 2+(4(11)-7)^o=180^o$

$m\angle 2=180^o-152^o=28^o$

16+ y =24<br> What is the value of y?

<em /> $\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}$

When solving an equation, we need to make sure that all variables are on one side and all numbers are on the other side.

Since we have numbers on both sides, we need to move all of them to one side:-

$\tt{16+y=24}$

$\tt{y=24-16}$

$\tt{y=8}$
