Answer:
r = 2. The center is at (0, 3).
Step-by-step explanation:
Compare the given x ^ 2 + (y - 3) ^ 2 = 4 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 0, k = 3 and r = 2. The center is at (0, 3).
Answer:
correct option is B. 10%
Step-by-step explanation:
given data
assets A annualised volatility = 10%
assets B annualised volatility = 20%
solution
we both A and B assets are 10% and 20% respectively
and we know that to achieve smallest portfolio volatility
we need to invest completely in the asset which has least volatility
and volatility can not be less than the asset having least volatility
so here minimum volatility that can be achieved is = 10%
so correct option is B. 10%
You can find equivalent ratios<span> by multiplying or dividing both sides by the same number</span>
Answer:
a = 1
b = - 1
Explanation:
To know the values of a and b, we need to solve the following equation:
So, replacing cos(-π/4) by √2/2 and sin(-π/4) by -√2/2, we get:
Applying the distributive property:
Therefore, we can complete the equation as:
It means that a = 1 and b = - 1.
