Hello :
note : the polar coordinates is : (r , <span>θ)
</span>Another representation is (x, y) : x=r cos(θ) and y = sin(θ) and : r =<span>√(x²+y²)
</span>in this exercice : r = 1 and θ = 5<span>π<span>/6
so : x= 1.cos(</span></span>5π/6) and y = 1. sin(5π/6)
but : cos(5π/6) = cos (π - π/6) = - cos(<span>π<span>/6 ) = (- </span></span><span>√3)/2
</span>sin(5π/6) = sin (π - π/6) = sin(π/6 ) =1/2
Another representation is : ( (- √3)/2 , 1/2)
Answer:
e
Step-by-step explanation:
mean = 16 ounces
standard deviation = 0.2×16 ounces = 3.2 ounces
standard deviation of sample mean = 3.2/√64 = 3.2/8 =0.4
z value of 15 is (15-16)/0.4 = -1/0.4 = -2.5, using z-table corresponding p value = 0.00621
P(average <15) =0.00621
so answer is (e)
D, because tutoring and receptionist is UPTO 20 hours and the money is AT LEAST 200
Answer:
B
Step-by-step explanation:
This is because when you reflect a triangle the letters need to be the same distance from the point of reflection (the y axis) when you count everything out B is the only answer with all of the correct coordinates.

Yes, it is
