186,453,000 ≈ 190,000,000

190,000,000 = 1.9 × 10⁸

V = π * 5² * 15

Just follow the order of operations:

Parenthesees, Exponents, Multiplication and Division, Addition and Subtraction

V = π * 25 * 15

V = 375π

V ≈ 1178.097 cubic units

Click the " 2nd " button in the top left.

Click " atan ".

Click the " 2nd " button again.

Type the number that you want to get the inverse tangent of.

Close the parenthese, just because it's good to.

Click " = "

Or you can just type in " atan(  ".

-2x²y³(4x³y - 7x²y - 3x)

If you're trying to multiply this out, all you need to do is distribute.

That just means multiply whatever is outside the parenthesees by every single thing inside the parenthesees and add the products together.

(-2x²y³)(4x³y) + (-2x²y³)(-7x²y) + (-2x²y³)(-3x)

Rearrange the factors in each term to make it easier to see, if you want.

(-2)(4)(x²)(x³)(y³)(y) + (-2)(-7)(x²)(x²)(y³)(y) + (-2)(-3)(x²)(x)(y³)

Then just multply them together.

-8x⁵y⁴ + 14x⁴y⁴ + 6x³y³

You just said to tell when a vertical asymptote occurs, so I will just tell one place that it occurs at for each of these. But keep in mind that if you add π, or 180º, another asymptote will occur there too. And each of these functions will have an infinite number of asymptotes because they are cyclic, which just means they repeat themselves over and over.

tan is sin/cos, and cos = 0 at π/2

tan x has a vertical asymptote at x = π/2

cot is cos/sin, and sin = 0 at 0π

cot x has a vertical asymptote at x = 0

sec is 1/cos, and cos = 0 at π/2

sec x has a vertical asymptote at x = π/2

csc is 1/sin, and sin = 0 at 0π

csc x has a vertical asymptote at x = 0

I put the answers in radians just because I think that makes the most sense for this question,

but if you need it in degrees: π/2 = 90º and 0 = 0º

(3v + 4)(6 + v)=0

Set each factor equal to zero.

If either of them is zero, then the whole thing is zero.

Zero times anything is zero.

So

3v + 4 = 0                                         or                               6 + v = 0

Subtract 4 from both sides.                                                Subtract 6 from both sides.

3v = -4                                                                                v = -6

Divide both sides by 3.

v = -4/3

Test both of these values for v and see that they both work!

area = π(radius)²

25.12 = π(radius)²

25.12/π = radius²

√(25.12/π) = radius

circumference = 2π(radius)

circumference = 2π√(25.12/π)

circumference ≈ 17.767

Hahaha good one EP 

Hmmmmmmmmmmm..........is that really true?

Get a common denominator.

\(\frac{1}{3} - 2 =\frac{1}{3} - \frac{2}{1}=\frac{1}{3} - \frac{2*3}{1*3}=\frac{1}{3} - \frac{6}{3}=\frac{1-6}{3}=\frac{-5}{3}\)
