Answer:
You <u>solve</u> the equation.
Step-by-step explanation:
The process of finding variable values that make the equation true is called <em>solving</em> the equation.
Step-by-step explanation:
I used a calculator but the answer is 1 1/6
Answer:
Step-by-step explanation:
To simplify polynomials, find the like terms which look and sound the same then combine the coefficients of each to simplify.
Answer:
X = 0, π/2 in the interval [0, 2pi).
Step-by-step explanation:
Use the auxiliary angle method:
R sin(x + a) = Rsin x cos a + Rcos x sin a = 1
sin x + cos x = 1
Comparing coefficients:
R cos a = 1 and R sin a = 1, so
tan a = R sin a / R cos a = 1
So a = π/4 radians.
Also R^2(sin^2 a + cos^2 a) = 1^2 + 1^2 = 2
Therefore R = √2.
So √2 sin (x +π/4 = 1
sin x + π/4 = 1/√2
x + π/4 = π/4
x = 0 radians
Also
x = 0 + π/2 = π/2.
10 - 6x = 160 - 10x
+6x +6x
-10 + 6 = -4
10 = 160 - 4x
-160
10 - 160 = -150
-4x = -150
-4x/4 = -150/-4
x= 37.5
