Answer:
Step-by-step explanation:
300 degrees is in the fourth quadrant (it's between 270 and 360); sine is negative in the fourth quadrant.
Given we're in the fourth quadrant, the reference angle is 360 - 300 = 60 degrees
sin(60°) = 
And since sine is negative, this value turns negative:
sin(300°) =
I’m not sure but try connects it helps me a lot with my math homework
Allison can make four parfaits because you need 1/8 cup of yogurt and Allison has 1/2 cup of yogurt. So the half of the cup would give her 4 * 1/8 to equal 1/2.
Let's solve your equation step-by-step.
x3+5x2+2x+10=0
Step 1: Factor left side of equation.
(x+5)(x2+2)=0
Step 2: Set factors equal to 0.
x+5=0 or x2+2=0
x=−5
Answer:
x=−5
We proved that formula using the trigonometry relations sin3A + sinA = 4sinAcos^2A.
In the given question,
We have to prove the formula sin 3A+sin A = 4sinAcos^2A
The given expression is sin 3A+sin A = 4sinAcos^2A
To prove the formula we take the left side terms to the right side terms
The left side is sin 3A+sin A.
As we know that sin 3A = 3sinA − 4sin^3A
To solve the left side we put the value of sin 3A in sin 3A+sin A.
=sin 3A+sin A
=3sinA − 4sin^3A+sin A
Simplifying
= (3sinA+sin A) − 4sin^3A
= 4sinA − 4sin^3A
Taking 4sinA common from both terms
= 4sinA(1 − sin^2A)
As we know that cos^2A=1 − sin^2A. So
= 4sinAcos^2A
We proved the right hand side.
