Answer : The cost of 21 meter of ribbon is, $28.5

Step-by-step explanation :

As we are given that, the cost of 14 meter of ribbon is $19.

Now we have to determine the cost of 21 meter of ribbon.

As, the cost of 14 meter of ribbon = $19

and, the cost of 1 meter of ribbon = \frac{1}{14}\times \$ 19

So, the cost of 21 meter of ribbon = \frac{21m}{14m}\times \$ 19

                                                        = $ 28.5

Therefore, the cost of 21 meter of ribbon is, $28.5

Solve for j. 144j2 + 21 = 85
Sphinxa [80]

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 \sqrt{64}/ \sqrt{144}, or 8/12, which we can now simplify to 2/3. Hope this helps!

Find the general solution of y\"+9y=t^2*e^3t+6.
Fofino [41]
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>
