Find the following trigonometric values.

Mathematics
1 answer:
Alona [7]2 years ago
6 0

Answer:

\cos(150)\degree = -\frac{\sqrt{3}}{2}\\

\sin(150)\degree=\frac{1}{2}\\

Step-by-step explanation:

Formulae used:

cos (180°-θ) = -cos θ

sin (80°-θ) = sin θ

Therefore,

\cos(150)\degree = cos(180-30)\degree = -\cos(30)\degree = -\frac{\sqrt{3}}{2} \\\\\sin(150)\degree = sin(180-30)\degree = \sin(30)\degree = \frac{1}{2} \\\\

Whats the product of 6 and<br><br> q
nevsk [136]

Answer:

6q or 6 * q

Step-by-step explanation:

As you do not know what the value of the variable q is, you are essentially changing it from word form to expression form.

"product" in math means multiply, so you are multiplying 6 with q.

6q is your answer.

Find the area of the rectangle below by multiplying its length and width.
wariber [46]

Hello!

When multiply binomials together, we should use the FOIL method.

The FOIL method is an acronym for First, Outer, Inner, and Last.

First, let's set up the expression.

(7x - 1)(3x - 2)

Now, we can multiply in accordance with the FOIL method.

First: 7x · 3x = 21x²

Outer: 7x · -2 = -14x

Inner: -1 · 3x = -3x

Last: -1 · -2 = 2

Now, we simplify the inner terms.

21x² - 14x - 3x + 2

21x² - 17x + 2

Therefore, the area of the rectangle is 21x² - 17x + 2.
