Answer:
Cosθ= -√2/3
Sinθ= -√7/3
tanβ= 4/3
Sinβ= 4/5
Cosβ= 3/5
sin(θ+β) = sin(θ)cos(β)+cos(θ)sin(β)
(-√7/3)(3/5) + (-√2/3)(4/5)
-√7/5 - 4√2/15
Answer:
(5sqrt(2), 45 deg)
(-5sqrt(2), 225 deg)
Step-by-step explanation:
(x,y)=(5,5)
So theta=arctan(5/5)=arctan(1)=45 degrees
Now r! r=sqrt(x^2+y^2)=sqrt(5^2+5^2)=sqrt(50)=sqrt(25)sqrt(2)=5sqrt(2)
So one polar point is (5sqrt(2) , 45 degrees)
Now if we do 180+45=225 degrees... this puts us in the 3rd quadrant... to get back to quadrant 1 we just take the opposite of our r
so another point is (-5sqrt(2) , 225 degrees)
Answer: $70
Step-by-step explanation: 45.50/ 65%
Answer:
Answer What
Step-by-step explanation:
Answer:
33
Step-by-step explanation:
Because 66 is 200% just divide that by 2. Then 33 would be 100%
