Use the unit circle to find the value of tan (-180°).

Mathematics

loris [4]3 years ago

In order to evaluate the tangent function "visually", you have to draw a vertical line tangent to the circle (i.e. the line x=1), and extend the radius until it meets that line.

Since the angle -180° makes you land on point (-1,0), if you extend the radius you'll meet the vertical line at point (1,0).

The tangent is the y-value of this point, and thus it's zero.

Which number has an absolute value that is equal to the absolute value of 32?
Gennadij [26K]

Answer:

-32

Step-by-step explanation:

The absolute value of a number is its distance from 0. Since distance is always positive the absolute value is the same number but positive. So the absolute value of -32 and 32 would both be 32 because they have the same distance from 0.

How do i solve this radical expression? It has to do with factoring i know that.
MAVERICK [17]
Firstly it's not a radical expression.

You can factorize the numerator x²+12x+36 = (x+6)²

Factorize the denominator 12x+72 = 12(x+6)


=(x+6)² / 12(x+6) , simplify. Answer = (x+6)/12

Write a polynomial function in standard form with zeros at −3, −1, and 1.
Annette [7]

Answer:

f(x) = {x}^{3}  + 3 {x}^{2}  - x -3

Step-by-step explanation:

The given polynomial has zeros at:

x=−3, x=−1, and x=1.

This means that:

x+3, x+1, and x-1 are all factors of this polynomial.

The factored form of this polynomial is :

f(x) = (x + 3)(x + 1)(x - 1)

We expand the last two factors using difference of two squares.

f(x) = (x + 3)( {x}^{2}  - 1)

f(x) = x ( {x}^{2}  - 1) + 3( {x}^{2}  - 1)

f(x) = {x}^{3}  - x+ 3 {x}^{2}  -3

f(x) = {x}^{3}  + 3 {x}^{2}  - x -3

This is the standard form because it is now in decreasing powers of x.
