Part of a circuit has two resistors connected in parallel as shown in the figure. R1 is a constant resistor of 10 ohm, while R2 is a variable resistor with resistance that varies at a rate of 2 ohms per minute. The total, or effective, resistance, R, provided by this circuit is given by:
1/R= 1/R1+1/R2

At what rate does the effective resistance change when R2 is 100 ohms? Round off your answer to four decimal places.

Step-by-step explanation:

R = R1 R2/(R1+R2)

R1 is constant

dR = R1 [(R1+R2) dR2- R2 dR2]/ (R1+R2)^2

dR/dt = R1 dR2/dt [R1]/(R1+R2)^2

dR/dt = 100(2) /(110)^2

it is true

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
