4. 1 less than twice the square of a number

givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

Stock in Daenerys Industries has a beta of 1.2. The market risk premium is 5 percent, and T-bills are currently yielding 4.2 per

sasho [114]

Answer:

The best estimate of the company's cost of equity is 10.05%.

Step-by-step explanation:

Using growth rate model formula, the cost of equity can be calculated as follows:

Cost of equity as per growth rate model = (D1 / P) + g ................ (1)

D1 = Most recent dividend * (1 + g) = $1.40 * (1 + 0.05) = $1.47

P = Current price per share = $30

g = Growth rate of dividend = 5%, or 0.05

Substituting the values into equation (1), we have:

Cost of equity as per growth rate model = ($1.47 / $30 ) + 0.05

Cost of equity as per growth rate model = 0.099. or 9.90%

Using Capital Asset Pricing Model (CAPM) formula, the cost of equity can be calculated as follows:

Cost of equity as per CAPM = Risk free rate + (Beta * Market risk premium) = 4.2 + (1.2 * 5) = 10.20%

Therefore, we have:

Best estimate of Cost of equity = (Cost of equity as per growth rate model + Cost of equity as per CAPM) / 2 = (9.90% + 10.20%) / 2 = 10.05%

Therefore, the best estimate of the company's cost of equity is 10.05%.

Plz help im cheeks at math

Vera_Pavlovna [14]

We have an exponential with a fractional base and a positive exponent, and a positive sign at front. Each time we multiply a fraction between zero and one by itself it gets smaller. So as x increases we'll go to zero. As x decreases it goes to positive infinity, as negative powers are the reciprocals of positive power.

The left end approaches positive infinity and the right end approaches zero.

Answer:

Value of x1 = 10 and x2 = -3

Step-by-step explanation:

$when \: we \: multiply \: the \: above \: matrices \\ we \: get \\ 2x1 + 6x2 = 2 \: \: \: \: and \\ 0x1 + 1x2 = - 3 \\ then \: \: x2 = - 3 \\ on \: substituting \: x2 = - 3 \:\\ in \: first \: equation \: \\ 2x1 + 6( - 3) = 2 \\ 2x1 - 18 = 2 \\ 2x1 = 20 \\ x1 = \frac{20}{2} \\ x1 = 10$
