Answer to Problem 19E
Explanation of Solution
Given information: The triangle:
Calculation:
I am going to solve all this with special triangles.
The one at left is the right triangle (a 30-60-90 degree triangle) with the long side equal to 12. That means the short side is half of that or h = 6.
The middle side is the short side times the
The triangle on the right is a 45-45-90 degree triangle and we know h = 6 so m = 6 since it is isosceles.
The hypotenuse is the short side times
Thus,

- can you explain why the answer is 1/3arrow_forwardThe position of a particle that moves along the x-axis is defined by x = - 3t^2 + 12^t - 6 f, where t is in seconds. For the time interval t = 0 to t = 3 s, (1) plot the position, velocity, and acceleration as functions of time; (2) calculate the distance traveled; and (3) determine the displacement of the particleshow the graph and write the solution with a penarrow_forwardThe position of a particle that moves along the x-axis is defined by x = - 3t^2 + 12^t - 6 f, where t is in seconds.
