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>
25.5
Step-by-step explanation:
The way to do this is:
80 * 3.14 equals to roughly 25.5
Answer:
Each side of the octagon a length of 6 cm
Step-by-step explanation:
Divide the perimeter by the amount of sides the shape has.
48 ÷ 8 = 6
Answer:
y ≤ −6x−21
Step-by-step explanation:
-12x – 2y ≥ –42
– 2y ≥ 12x –42
-2(– 2y ≥ 12x –42)
y ≤ −6x−21
