Answer:
The coordinates of point P is
Step-by-step explanation:
Here, the coordinates of the point A and B are given as:
A (3,6) and B(10,-2)
Let us assume the point P (a,b) divides the line segment AB in ratio 1:3.
Now, by SECTION FORMULA:
The coordinate of the point (a,b) which divides the line segment with points (x1,y1) and (x2,y2) in ratio m1 : m2 is given as:
Now, here putting the values of the points A and B as (3,6) and (10,-2) adn ratio m1 : m2 as 1:3, we get:
Hence, the coordinates of point P is
Answer:
This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
A = 84 mg
Answer:
Possibly tell someone some dramatic news or put them into a dramatic situation? I'm not quite sure but that's a way to get a reaction.
Step-by-step explanation:
Answer:
A) The maximum error in the calculated surface area:
Relative error:
B) The maximum error in the calculated volume:
Relative error:
Step-by-step explanation:
A) The formula for the surface area is:
The measured value is the circumference which is equal to:
then the radius is:
Substituting in the formula of the surface:
Using the formula to calculate the error:
Where is the variable measured and is a function of ().
We have C=80cm and dC=0.5cm
The relative error is the maximum error divide by the total area. The total area is:
B) The formula for the volume is:
Using
The maximum error is:
The calculated volume is:
The relative error is:
