Answer:12,450
Step-by-step explanation: Since the climber descends to meet a fellow climber by 200 ft you are going to subtract so the equation is going to be 12,740-200 ft so what does that equal it equals 12,540 ft because it is only subtracting 740-200 ft so 740-200=540 so your answer would more likely be 12,540 not the negative answer.
Answer: $20, 176
Step-by-step explanation: All you have to do is multiply how much she gets paid per hour by the number of hours that she works so it would just be 9.70*40 which equals 388. Then you have to multiply that answer by the number of weeks in a year so it would be 388*52 and your final answer would be $20, 176.
Answer:
The curvature is 
The tangential component of acceleration is 
The normal component of acceleration is 
Step-by-step explanation:
To find the curvature of the path we are going to use this formula:

where
is the unit tangent vector.
is the speed of the object
We need to find
, we know that
so

Next , we find the magnitude of derivative of the position vector

The unit tangent vector is defined by


We need to find the derivative of unit tangent vector

And the magnitude of the derivative of unit tangent vector is

The curvature is

The tangential component of acceleration is given by the formula

We know that
and 
so

The normal component of acceleration is given by the formula

We know that
and
so
