The angles must be opposite to be equal to each other so parallelogram ABCD
Line AB is parallel to DC and line AD is parallel to BC
C is the correct answer
We are given with the equation y"+ 9 y = t^2 * e^3 t + 6 and asked to determine the general solution to this equation. we convert the equation into r^2 + 9 = 0. The solution to this equation is r = +/- 3i. This solution converted to trigonometric function is equivalent to <span>y</span>= <span>C1 </span>cos3t + <span>C2 </span>sin<span>3t. </span>
In this instance the distance will be the hypotenuse of a right angle triangle.
x = 300/sin30 = 600
They are 600 ft away from each other
The constant of proportionality would be: y= 2/3x
