It's very easy to come up with linear functions if all you have to do is make sure that your slope is more than -1 and less than 0. The easier slope to choose would be -0.5. To rest of the equation (b) can be filled out as you choose:
y = -0.5x + b
b = any constant value (ex. 1, 3, 7)
Answer: The voltage across an identical resistor = 60 Volts
Step-by-step explanation:
Step 1
Given that voltage across the resistor is directly proportional to the current running through the resitor.
Mathematically, it would be represented as
Voltage ∝ Current
Introducing the constant of proportionality, k which represents the Resistor as it is constant.
we have that
Voltage = K x Current
When current = 12 amps and voltage = 480v, the constant of proportionality K
480 = k x 12
k = 480/12
k= 40
Step 2 ,
when current = 1.5 amps
Voltage = ?
Using our equation that
Voltage = K x Current
Voltage = 40 x 1.5
Voltage = 60 Volts
Answer:
445.5 minutes
Step-by-step explanation:
45/50 to see how many minutes it takes for each square foot of floor and it equals .9
Next multiply 495 and .9 together and the answer you will get is 445.5
