Answer:
Step-by-step explanation:
Given circle has equation as
Center = P(0,0)
The point of contact of tangent = 
Q
Since tangent is perpendicular to the radius at the point of contact, we have
Slope = 
as slope of perpendicular to tangent
So tangent slope would be
-1/slope of this line
= 
We have point on this line as given point
So using point slope form equation of tangent is
Answer:
B.16 mins start from home to school or school to home
Step-by-step explanation:
I. When bike is faster than walk 3 times
Jane is in the middle of way to school
if she walk mid point to school is 4 mins
then mid point to home is 4 * 3 = 12 mins
School + Home = Total Mins
4 + 12 = 16

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
