The alt-azimuth coordinates i measure for polaris are 37°, 0°. the latitude i am observing from is degrees n.

37 degrees North

The alt-azimuth coordinates (also called horizontal coordinates) are coordinates centered on the Earth and describe the position of an object with respect to the local visible horizon and constantly change with time.

The Azimuth is measured from the North to the East, starting from 0 degrees in the North, 90 degrees in the East and so on. That is, it is measured in a clockwise direction.

The Altitude is measured from the horizon to the zenith, starting at 0 degrees for the horizon and 90 degrees for the zenith.

The equivalent for these coordinates are the geographic coordinates Latitude and Longitude, this means:

Azimuth is equivalent to the Longitude

Altitude is equivalent to the Latitude

In this case we have the coordinates of polaris as:

Altitude:

Azimuth:

Which is equivalent to a latitude of 37 degrees North

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%
