First, find the LCD of the two denominators.
Multiples of 5: 5, 10, 15, 20
Multiples of 20: 20
The LCD is 20.
Second, make the denominators the same as the LCD. / Your problem should look like:
Third, simplify so that the denominators are the same. / Your problem should look like:
Fourth, combine the denominators. / Your problem should look like:
Fifth, simplify. / Your problem should look like:
Answer as fraction:
Answer as decimal: -0.65
440
(this is filler to hit the 20 character limit)
Answer:
To know the equation of line we need 2 things
slope and y intercept
slope= (y2-y1)÷(x2-x1)
y intercept is y when x =0
then put them in formula f(x)=mx+c
m = slope, c= y intercept
1: slope = 1. y intercept = 4
f(x)=x+4
2: slope = -9/2. y intercept = 11/2
f(x)= -9/2x+(11/2)
3: slope = 1/3. y intercept = -11/3
f(x)=x/3+(-11/3)
4: slope = -1. y intercept = 7
f(x)=-x+7
5: slope = 1. y intercept = -2
f(x)=x+-2
Answer:
f=u+2
Step-by-step explanation:
math
The solutions are: θ = 90º, 270º, 30º, and 150º
Given,
sin2θ = cosθ
sin2 θ = 2sinθ cosθ
2sinθ cosθ = cosθ
2sinθ cosθ - cosθ = 0
factor
cosθ(2sinθ-1) = 0
cosθ = 0 or 2sinθ - 1 = 0
cosθ = 0 when θ=90º or θ=270º (look on the unit circle)
2sinθ - 1 = 0
2sinθ = 1
sinθ = 1/2
look at the unit circle and see that sinθ=1/2 when θ=30º
sin is positive in Quadrant2 as well as Quadrant 1
180º-30º=150º
θ=150º
answers: θ=90º, 270º, 30º, and 150º
