Answer:

Step-by-step explanation:

∠S=180-(54+62)=180-116=64°

using sin formula

$\frac{x}{sin~64} =\frac{7}{sin~62} \\x=\frac{7~sin~64}{sin~62} \approx 7.1256 \approx 7.13$

Explain how multiplying with 6 is like multiplying with 3

uranmaximum [27]

Multiplying with 6 is a mathematical process similar to multiplying with 3, in that setting up the greatest common factors between the two is easy due to the fact that 6 is a multiple of 3. As 6 is simply 3 doubled, any multiple of 6 will be the relative multiplation for 3 doubled.

Answer:

$\frac{dh}{dt}=\frac{160}{169\pi } ft/min$

Step-by-step explanation:

This is a classic related rates problem. Gotta love calculus!

Start out with the formula for the volume of a cone, which is

$V=\frac{1}{3}\pi r^2h$

and with what we know, which is $\frac{dV}{dt}=40$

and the fact that the diameter = height (we will come back to that in a bit).

We need to find $\frac{dh}{dt}$ when h = 13

The thing we need to notice now is that there is no information given to us that involves the radius. It does, however, give us a height. We need to replace the r with something in terms of h. Let's work on that first.

We know that d = h. Because d = 2r, we can say that 2r = h, and solving for r gives us that $r=\frac{h}{2}$ .
