y= -8

write and solve an equation to find the value of x. 4.8, 1.6, 5.2, x; mean 3.7

Since the mean is 3.7 and there are 4 items, therefore the total of the 4 items should be:

3.7 x 4 =14.8

14.8 - [4.8+1.6+5.2+x] =0

14.8 - [11.6 + x]=0

x =14.8 - 11.6 =3.2

WARNING! I'm no expert in this type of investment, but I will give it a go and you decide!!.

The risk free rate in a given economy is 5% and the expected return on the market is 10%. I am buying a firm with a perpetual annual cash flow of $2000. If I think the beta of the firm is 0.8 when the beta in fact is 1.6, how much more will I offer for the firm that it is really worth?

The expected return at your assumption of beta of 0.8 would be:

5% + 0.8[10% - 5%] = 9%. Therefore, the current value of perpetual annuity would be:

$2,000 / 0.09 =$22,222.22 at your assumption

The expected return at the actual beta of 1.6 would be:

5% + 1.6[10% - 5%] =13%. Therefore, the current value of the perpetual annuity would be:

$2,000 / .13 =$15,384.62 at actual beta of 1.6. Therefore, you would be paying:

$22,222.22 - $15,384.62 =$6,837.60 extra at your assumption of beta of 0.8.

Let's show you through example.

Example: (1/2)/(1/4)

What you do is you flip the second fraction, in this case it is 1/4, and multiply.

1/2 * 4 = 2

So one-half divided by one-fourth is two.

Simplify the following:
2+5 i-(9 i-4)

-(-4+9 i) = 4-9 i:
4-9 i+2+5 i

4-9 i+2+5 i = (4+2)+(-9 i+5 i) = 6-4 i:
6-4 i

Factor 2 out of 6-4 i giving 2 (3-2 i):
Answer: 2(3 - 2i)

YOU KEEP THE FIRST FRACTION AND SWICH THE 2ND ON

That joke got old along time ago

you take a fraction and then you divide it

how do you solve (cos 15)=12/x

(cos 15)=12/x

0.9659 =12/x cross multiply

0.9659x = 12 divide both sides by 0.9659

x =~12.423

(x+6)(x−6)=x​2​​+cx+d

(x+6)(x−6)=x^2 - 36. What does the RHS stand for?

I think your foot steps am i right

Solve for t over the real numbers:
e^(-0.9 t) = 0.73

e^(-0.9 t) = e^(-9 t/10) and 0.73 = 73/100:
e^(-9 t/10) = 73/100

Take reciporicals of both sides:
e^(9 t/10) = 100/73

Take the natural logarithm of both sides:
(9 t)/10 = log(100/73)

Multiply both sides by 10/9:
Answer: t = 10/9 log(100/73) =0.34967860.......this is the "natural log".
