What is the volume of the solid?
kherson [118]

Answer:

The volume of a solid is the measure of how much space an object takes up. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units⋅3 units⋅5 units = 30 cubic units.4

What if this function simplified?
almond37 [142]

Hi!

Let's first expand the cotangent of theta.

You'll probably know that tangent will be "y/x", or \frac{sin(x)}{cos(x)}, and cotangent is the reciprocal of this, meaning that it is "x/y" or \frac{cos(x)}{sin(x)}.

That means that we are now given this equation.

cos(x)\frac{cos(x)}{sin(x)}+sin(x)

That'll multiply to:

\frac{cos^2(x)}{sin(x)}+sin(x)

We'll want a common denominator to add by multiplying sin(x) to both top and bottom of the second term:

\frac{cos^2(x)}{sin(x)}+\frac{sin^2(x)}{sin(x)}

\frac{cos^2(x)+sin^2(x)}{sin(x)}

Pythagorean Identity states that sin^2(x)+cos^2(x)=1, so substitute that in:

\frac{1}{sin(x)}

Which simplifies to:

csc(x)

Hope this helps!
