Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) =
OP.Cosθ = 1×Cosθ =
Cosθ =
θ = , where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ = , where n = integer
Common value of θ will be, θ =
Option B will be the answer.
Answer:
20 tshirts and 150 keychains
Step-by-step explanation:
let tshirts be 10x and keychains be 2y
now make a Quadratic equation,
10x+2y=500
=let x = 20
=(10×20)+2y=500
=200+2y=500
=2y=300
y=300/2 = 150
therefore 20 tshirts and 150 keychains sumsup their goal of 500 dollars
The equation will shift up two points
Yes because you have the follow the order of operations.
