Double angle formulae involve trigonometric functions of double angles and in order to get its value you must consider the following:
-derive the double angle formula from additional formula
-write the formula for the angle in alternative form
-use the formula to write trigonometric expressions in different forms
-use the formula in the solution of trigonometric equations
And the answer would be 4sin(theta)cos(theta)cos(2theta)
Answer:
1.) It has one solution (–5, 5).
if you click on the photo it will show you how to get the answer. I hope this helps you.
Answer:
3x + 6y
Step-by-step explanation:
so the perimeter is 12x + 8y and a side is 4x-2y so that means that side and the side across is 8x-4y so you put it all to one side to get 6x +12y then divide that by 2 to find 1 side so the side is 3x + 6y
The answer is $7.14!
All you have to do is subtract 10 by 2.86.
Answer:
A. Linear
Step-by-step explanation:
The equation (
) is a linear equation. As per its definition, a linear equation is an equation where all terms are to the first degree, meaning that none of the terms have an exponent. The equation, () falls under this category, as none of its terms has an exponent, therefore, the equation is a linear equation.
