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)
Its an exponential growth
Answer:
1.) It's 20th century painting
2.) 0.5 probability
Step-by-step explanation:
If the universal = 60
We need to first get the value of X. That is,
x (x - 2) + x + 2x + 8 + 10 = 60
First open the bracket
x^2 - 2x + x + 2x + 8 + 10 = 60
x^2 + x + 18 = 60
x^2 + x - 42 = 0
Factorise the above equation
x^2 + 7x - 6x - 42 = 0
x (x + 7) -6(x + 7) = 0
x = 6 or - 7
Since x can't be negative, so we will ignore -7
The value for T = 6(6 - 2) = 6×4 = 24
The value for B = 2(6) + 8 = 12 + 8 = 20
If a painting is chosen from random,
If it's from 20th century, the probability will be 34/60 = 0.567
If it's from British painting, the probability will be 30/60 = 0.5
We can therefore conclude that it's from 20th century painting since it has higher value of probability.
The the probability of choosing a British painting will be 30/60 = 0.5
The correct answer is D because he got a 92% and she got 47 out of 50 which she will be little higher.
