When a bulb is connected to a 12V cell a current of 0.05A flows through the bulb. What is the resistance of the bulb?
Use the equation

resistance (R) = (V) voltage/ (I) current

A 0.6 Ω
B 6 Ω
C 24 Ω
D 240 Ω

=0.6

Explanation:

R=v*I

R=12*0.05

R=0.6

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
