Answer 1

Answer:   16x⁴ - 121x² = 0
  x²(16x²) - x²(121) = 0
  x²(16x² - 121) = 0
x²(16x² + 44x - 44x - 121) = 0
x²(4x(4x) + 4x(11) - 11(4x) - 11(11)) = 0
  x²(4x(4x + 11) - 11(4x + 11)) = 0
  x²(4x - 11)(4x + 11) = 0
  x² = 0 or 4x - 11 = 0 or 4x + 11 = 0
√(x²) = √(0) + 11 + 11 - 11 - 11
  x = 0   or   4x = 11    or    4x = -11
4 4 4 4
x = 2³/₄   or      x = -2³/₄

Solution Set: {0, ±2³/₄}

What is the solution of the system? {5x−y=−21 x+y=−3 Enter your answer in the boxes. (( , )

Answer:

The solution of the given system of equation is (-4, 1)

Step-by-step explanation:

Given system of equation 5x− y = −21 and x+y= −3

We have to find the solution of the given system of equation.

Consider the

Given system of equation

5x− y = −21 .......(1)

x + y = −3 .......(2)

Adding (1) and (2) , we have,

⇒ 5x - y + (x + y ) = -21 + (-3 )

⇒ 5x - y + x + y = -21 - 3

⇒ 5x + x = -24

⇒ 6x = -24

⇒ x = -4

Substitute x = -4 in (2) , we get,

x + y = −3 ⇒ (-4) + y = −3 ⇒ y = -3 + 4 ⇒ y = 1

Thus, the solution of the given system of equation is (-4, 1)

5x - y = -21
y = 5x + 21

Substituting into:
x + y = -3

x + 5x + 21 = -3
6x = -24
x = -4
y = 5(-4) + 21
y = 1

Solution: (-4,1)

has a beta of 12 , and iss realted rote of return has averaged 13.0% over the past 5 vears. Round veur enswer to twe dedimal places.

Answers

To calculate the expected rate of return for an investment with a beta of 12 and assuming the risk-free rate is not provided, you can use the Capital Asset Pricing Model (CAPM):

Expected Return = Risk-Free Rate + Beta * (Market Rate of Return - Risk-Free Rate)

Let's assume a typical risk-free rate of around 2% for this calculation:

Expected Return = 2% + 12 * (13.0% - 2%)

Expected Return = 2% + 12 * 11%

Expected Return = 2% + 132%

Expected Return = 134%

Rounding to two decimal places, the expected rate of return for the investment with a beta of 12 is 134.00%.
