The sign only changes when divided or multiplied by a negative number.
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>
Answer:
55 1/8 in. squared
Step-by-step explanation:
Area = L*W
3 1/2 * 1 3/4 = 6 1/8
because there are 9 planters we multiply 6 1/8 by 9 and you would get 55 1/8 in. squared
in. is for inches
