m_a_m_a [10]

Answer:

$\frac{a}{c}$ = $\frac{3}{20}$

Step-by-step explanation:

$\frac{a}{c}$ = $\frac{a}{b}$ × $\frac{b}{c}$ = $\frac{2}{5}$ × $\frac{3}{8}$ = $\frac{6}{40}$ = $\frac{3}{20}$

[Help] Classify the following triangle. Check all that apply.

Sonja [21]

The triangle is obtuse since it has an angle more than 90 degrees.
It also has 2 equivalent sides that are represented by the line, meaning it is isosceles.
Therefore,
C. and E. are correct.

The radius r of a cone is increasing at a rate of 4in/min. The height h of the cone is always 4 times the radius. Find the rate

AlekseyPX

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\qquad h=4r\implies V=\cfrac{\pi r^2 \cdot 4r}{3}\implies V=\cfrac{4\pi r^3}{3}\\\\
-----------------------------\\\\
\cfrac{dv}{dt}=\cfrac{4\pi }{3}\cdot 3r^2\cdot \cfrac{dr}{dt}\implies \cfrac{dv}{dt}=4\pi r^2\cdot \cfrac{dr}{dt}\qquad 
\begin{cases}
\frac{dr}{dt}=4\\\\
r=7
\end{cases}
\\\\\\
\cfrac{dv}{dt}=4\pi (7)^2\cdot 4$
