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:
8) Onaje is correct
9a) answers could be: 3(6y) or 4y + 6y + 8y or 2(2y + 3y + 4y)
b) all answers simplify to be 18y
Step-by-step explanation:
Paula is not correct because 16t + 9t ≠ 16 + 9 + 2t
16t + 9t only equals 25t
Answer:
C
Step-by-step explanation:
Quadratic model is shaped like a "U", or a parabola
Quartic model is shaped like a "W", highest degree is 4 (x^4).
Linear model is a line.
Cubic model is x^3, shaped like a curvy snake.
Looking at the graph, it <em>clearly</em> shows a line. So, linear model is the answer.
C is the correct answer.
Hello!
4/5 = (4 + 8)/x
4x = 5(12) = 60
x = 60/4 = 15
I hope this helps!
