Answer:
2/3
Step-by-step explanation:
I assume the 2 after the j is a square. So, we bring the 21 to the other side by subtracting it from both sides, getting 144j^2=64. Now we divide to get 64/144 = j^2. Make sure NOT to simplify it, it's perfect right now. The square root of that is
, or 8/12, which we can now simplify to 2/3. Hope this helps!
90 minus 32 is 58! You were off by two degrees:)

Answer:
Step-by-step explanation:
A=(3.14d^2)/4
A=0.785d^2
A=0.785(10^2)
A=78.5 yd^2
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>
