Answer:

5 - (N x 15)

81 x 15 = 1215

The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasin
hoa [83]

Answer:

\frac{dI}{dt}=-0.00016 A/s

Step-by-step explanation:

We are given that

By ohm's law

V=IR

R=389 ohm

I=0.03 A

\frac{dV}{dt}=-0.06V/s

\frac{dR}{dt}=0.07ohm/s

We have to find rate of change of current I means \frac{dI}{dt}

Differentiate the equation w.r.t t

\frac{dV}{dt}=\frac{dI}{dt}R+I\frac{dR}{dt}

Substitute the values then we get

-0.06=\frac{dI}{dt}\times 389+0.03\times 0.07

-0.06=389\frac{dI}{dt}+0.0021

-0.06-0.0021=389\frac{dI}{dt}

-0.0621=389\frac{dI}{dt}

\frac{dI}{dt}=\frac{-0.0621}{389}=-0.000160 A/s

Hence, the current I is changing at the rate=-0.00016A/s

16) w(x) = 4x + 4; Find w(x + 4)
Zina [86]

\\ \tt\hookrightarrow w(x)=4x+4=4(x+1)

Now

\\ \tt\hookrightarrow w(x+4)=4(x+4+1)

\\ \tt\hookrightarrow w(x+4)=4(x+5)

\\ \tt\hookrightarrow w(x+4)=4x+20
