Answer: 0.20 Ω
Step-by-step explanation:
From the question, we are informed that a multi-cab starter motor has a current of 60.0 A and a voltage of 12 V. The resistance of the starter motor will be calculated thus:
Current (I) = 60.0A
Voltage (V) = 12V
Resistance = Unknown
Since Voltage = Current × Resistance
Therefore, Resistance = Voltage / Current
= 12/60
= 0.20 Ω
The resistance of the motor is 0.20 Ω
Answer:
Tom was 17 years old and Jean was 11 years old
Answer:
A:
Let x represent the price of a ticket and R represent the revenue.
Let r be the number of 1 $ reduction.
So,
=> .......(1)
As given that for every dollar the ticket price is lowered, attendance increases by 3000.
So, if we reduce the ticket price by r dollars, the attendance will increase by 3000r.
Revenue = price of ticket X number of ticket sold
R = .....(2)
Substituting the value of r from (1) in (2) we get;
Solving this we get;
B:
To maximize revenue, we have to find the derivative for
Setting this to zero:
=>
=>
x = 8.5
To maximize the revenue, the price should be $8.50.
C:
When R=0
=>
=> Either x=0 or x=17
x = $0 means there is no price for ticket, that is not possible, so we will neglect it.
And x = $17 means that the ticket price is so high, and no revenue will be generated.
