If the circumference of a circle measures 3/4 π cm, what is the area of the circle in terms of π?

Vinil7 [7]

$\bf \textit{circumference of a circle}\\\\
C=2\pi r~~
\begin{cases}
r=radius\\
-----\\
C=\frac{3\pi }{4}
\end{cases}\implies \cfrac{3\pi }{4}=2\pi r
\\\\\\
\cfrac{3\pi }{4(2\pi )}=r\implies 
\boxed{\cfrac{3}{8}=r}\\\\
-------------------------------\\\\
\textit{area of a circle}\\\\
A=\pi r^2\qquad \qquad \implies A=\pi \left( \boxed{\frac{3}{8}} \right)^2\implies A=\pi \left( \cfrac{3^2}{8^2} \right)
\\\\\\
A=\cfrac{9\pi }{64}$

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.

Citrus2011 [14]

Answer:

$f'(x)=-5ae^{ax}=a f(x)$ , where a be a constant.

Step-by-step explanation:

Note: The given functions is a constant function because variable term is missing.

Consider the given function is

$f(x)=-5e^{ax}$

where a be a constant.

We need to find the derivative of the function.

Differentiate with respect to x.

$f'(x)=\dfrac{d}{dx}(-5e^{ax})$

$f'(x)=-5\dfrac{d}{dx}(e^{ax})$

$f'(x)=-5e^{ax}\dfrac{d}{dx}(ax)$ $[\because \dfrac{d}{dx}(e^x)=e^x]$

$f'(x)=-5ae^{ax}$

$f'(x)=a(-5e^{ax})$

$f'(x)=a f(x)$

Therefore, the derivative of the function is $f'(x)=-5ae^{ax}=a f(x)$ .

Is 6x-8 equal to 2(3x-5)? Also, btw the x is a variable... not the multiplication sign.

ivanzaharov [21]

No, it is not. Using the distributive property, multiply 2 to 3x and -5 to get 6x-10. 6x-8 does not equal 6x-10, they have the same coefficient by not the same constant.
