Answer:
The rate of change of the distance when x = 9 and y = 12 is .
Step-by-step explanation:
This is an example of a related rate problem. A related rate problem is a problem in which we know one of the rates of change at a given instant and we want to find the other rate at that instant.
We know the rate of change of x-coordinate and y-coordinate:
We want to find the rate of change of the distance when x = 9 and y = 12.
The distance of a point (x, y) and the origin is calculated by:
We need to use the concept of implicit differentiation, we differentiate each side of an equation with two variables by treating one of the variables as a function of the other.
If we apply implicit differentiation in the formula of the distance we get
Substituting the values we know into the above formula
The rate of change of the distance when x = 9 and y = 12 is

Answer:
1 1/2
hope this helped!
Step-by-step explanation:
2/3 = 4/6
4/6 + 5/6 = 9/6
9/6 = 1 1/2

Answer:
Step-by-step explanation:Angle from hour hand to minute hand at 1:15
At 1:15, the hour hand has moved 75 out of 720 possible times from the top of the clock. 75 times 0.5 degrees is 37.5 degrees.
At 1:15, the minute hand has moved 15 out of 60 possible times from the top of the clock. 15 times 6 degrees is 90 degrees.
90 - 37.5 = 52.5 degrees
Angle from minute hand to hour hand at 1:15
The angle from the minute hand to the hour hand is simply 360 degrees minus the degrees from the hour hand to minute hand that we calculated above.
360 - 52.5 = 307.5 degrees.
Now you know how to calculate the degrees of the two angles created by the hour hand and minute hand on a 12-hour clock at 1:15. Again, the two angles created by the hour hand and minute hand at one-fifteen are 52.5 degrees and 307.5 degrees.
Clock Angle Calculator
The angle made by the hour hand and minute hand on a clock at 1:15 is not all we have calculated. We have calculated the clock angles for every minute of the 12-hour clock. Get the degrees for another time here!
