Step-by-step explanation:
Speed = Distance / Time
given distance = 6km
time = 30 minutes = 30/60 hr = 1/2hr
speed =

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:
A=340m^2
Step-by-step explanation:
A=p times q divided by 2
20 times 34 is 680
680 divided bye 2 is 340
If brainiest is earned its greatly appreciated.
