The amount of resistance, y, in a circuit varies inversely to the current, x, in the circuit. when 10 ohms of resistance are used in the circuit, 12 amperes of current are present. when 5 ohms of resistance are used in the same circuit, 24 amperes of current are present. how many ohms of resistance are used in the circuit when 15 amperes of current are present? round your answer to the nearest hundredth, if necessary.

8 ohms

Step-by-step explanation:

given that y varies inversely as x then the equation relating them is

y = ← k is the constant of variation

To find k use either of the given conditions

y = 10 when x = 12 or y = 5 when x = 24, hence

k = 10 × 12 = 120

y = ← equation of variation

when x = 15, then

y = = 8

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%
