Well, first they're assuming that the m<ABC = 90

The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.

It is given that BD bisects <ABC, which means it splits the angle evenly..

Giving this equation: (x-5) = (2x-6)

Solving for x

-5 + 6 = 2x - x

1 = x

Find the volume of a cone with a radius of 3 millimeters and a 7 height of millimeters. Use 22/7 for 3.14 .

wolverine [178]

Answer:

Step-by-step explanation:

So the volume of a cone is $\pi r^2*\frac{h}{3}$

r = 3

h = 7

$9\pi *\frac{7}{3} = 21\pi$

$\frac{22}{7} *21=66$

Hey guys, real fast<br><br><br> how is the derivative of 3xlnx = 3+ln(x^3)

Harman [31]

You will need to use product rule.
The product rule is:
$\frac{d}{dx}[f(x)g(x)] = f'(x)g(x)+f(x)g'(x)$

$\frac{d}{dx}( 3x \ln x) =( \frac{d}{dx}(3x) \cdot \ln x )+ (3x \cdot \frac{d}{dx}(\ln x))\\\\ = 3\ln x + 3x\cdot \frac{1}{x}\\\\=3 \ln x + 3$

This can also be written as (using the log rules):
$3 \ln x + 3 = \boxed{\ln(x^3) + 3}$
