Apiece of land is shaped like a right triangle. two people start at the right angle of the triangle at the same time, and walk at the same speed along different legs of the triangle. if the area formed by the positions of the two people and their starting point (the right angle) is changing at 2 m squared divided by a comma then how fast are the people moving when they are 3 m from the right angle

They are moving at a speed of 2/3 meters per second.

Step-by-step explanation:

The field is shown in the attached figure below

As we can see that ant any instant of time Area of the triangle is given by

Differentiating both sides of the above equation with respect to time we get

Applying values in the given relation we get

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
