a shipping company charged $15 to ship a package and 5% to ensure the package what was total cost to ship this
postnew [5]

Answer:

15.75

Step-by-step explanation:

So we know 5% is 1/20 out of 100 (20x5=100) so then we need to set up the equation to find how much 5% of 15 is. Which is .75 cents. So we then add the 75 cents to the already $15 shipping fee to get an answer of 15 dollars and seventy five cents.

An alternating current E(t)=120sin(12t) has been running through a simple circuit for a long time. The circuit has an inductance
Dvinal [7]

Answer:

14.488 amperes

Step-by-step explanation:

The amplitude I of the current is given by

\large I=\displaystyle\frac{E_m}{Z}

where

\large E_m = amplitude of the energy source E(t).

Z = Total impedance.

The amplitude of the energy source is 120, the maximum value of E(t)  

The total impedance is given by

\large Z=\sqrt{R^2+(X_L-X_C)^2}

where

<em> R= Resistance </em>

<em>L = Inductance </em>

<em>C = Capacitance </em>

<em>w = Angular frequency </em>

\large X_L=wL = inductive reactance

\large X_C=\displaystyle\frac{1}{wC} = capacitive reactance

As E(t) = 120sin(12t), the angular frequency w=12

So

\large X_L=12*0.37=4.44\\\\X_C=1/(12*7)=0.012

and

\large Z=\sqrt{7^2+(4.44-0.012)^2}=8.283

Finally

\large I=\displaystyle\frac{E_m}{Z}=\frac{120}{8.283}=14.488\;amperes
