Answer:

2.3588

Step-by-step explanation:

Assuming your problem is: $\frac{2.3(6.82)}{7.74-1.09}$

We multiply the top and subtract the bottom, then divide the results together in the calc.

Rounded to 1 decimal place: 2.4

Answer:

≈2.36 (read below to make sure.)

≈2.4 (rounded to the tenths place)

Step-by-step explanation:

I'm assuming "--------------" is the fraction symbol.

$\frac{2.3*6.82}{7.74-1.09}=\\\\\frac{15.686}{6.65}=\\\\2.3587969924812030075187969924812$

≈2.36

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

$f'(0)=0$

Answer:

22°

Step-by-step explanation:

Triangle KJL ≅ Triangle MJL (RHS)

[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]

we come up to the conclusion that 4x + 6 = 3x + 10

x = 4

∴angle KJL = 4(4) + 6 = 22°
