-4

Step-by-step explanation:

First combine 2/3 - 4, the quantity enclosed by absolute value symbols  |  :

The LCD heree is 3.  Thus, 2/3 - 4 can be rewritten as 2/3 - 12/3, or -10/3.

Next, take the absolute value of this -10/3:  we get 10/3.

Then we have -10/3 divided by 5/6:

  -10

     3

     5

      6

Here we're dividing by a fraction.  An equivalent expression involves inverting 5/6 and multiplying the result by -10/3:

 -10      6

  *

   3       5

This reduces to -2(2), or -4

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
