Answer:

Step-by-step explanation:

k² = -18 - 9k

k² +9k + 18 = 0

k² + 6k + 3k + 3*6 = 0

k(k + 6) + 3 (k + 6) = 0

(k + 6) (k + 3) =0

-2v²- v +12 = -3v² + 6

-2v² - v + 12 + 3v² - 6 = 0

v² - v + 6 = 0

please help: What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2, 1)?

weqwewe [10]

Answer:

y = 5x + 11 or -5x + y = 11

Step-by-step explanation:

Given line:

-5x + y = 2

In slope-intercept form:

y = 5x + 2

The parallel line has the same slope and will look as:

y = 5x + b

This line passes through the point (-2, 1), substitute:

1 = 5*(-2) + b
b = 1 + 10
b = 11

So the line is:

y = 5x + 11

-5x + y = 11

Stock A ‘s returns have a standard deviation of 0.5, and stock B’s returns have standard deviation of 0.6.The correlation coeffi

galben [10]

Answer:

The variance of the profile is 0.2179.

Step-by-step explanation:

We are given the following in the question:

$\sigma_A = 0.5\\\sigma_B = 0.6\\\rho_{A,B} = 0.5\\w_A = 70\% = 0.7\\w_B = 30\% = 0.3$

Variance of portfolio is given by:

$w_A^2\sigma_A^2 +w_B^2\sigma_B^2 + 2w_Aw_BCov_{A,B}$

$Cov_{A,B} = \rho_{A,B} \times \sigma_A \times \sigma_B \\=0.5\times 0.5 \times 0.6\\=0.15$

Putting values, we get,

$w_A^2\sigma_A^2 +w_B^2\sigma_B^2 + 2w_Aw_BCov_{A,B}\\=(0.7)^2(0.5)^2 + (.3)^2(0.6)^2 + 2(0.7)(0.3)(0.15)\\=0.2179$

Thus, the variance of the profile is 0.2179.
