Evaluate the integral
Kruka [31]

Hello, please consider the following.

\displaystyle \begin{aligned} \int\limits^x {5sin(5t)sin(t)} \, dt &= -\int\limits^x {5sin(5t)} \, d(cos(t))\\ \\&=-[5sin(5t)cos(t)]+ \int\limits^x {25cos(5t)cos(t)} \, dt\\\\&=-5sin(5x)cos(x)+ \int\limits^x {25cos(5t)} \, d(sin(t))\\ \\&=-5sin(5x)cos(x)+[25cos(5t)sin(t)]+ \int\limits^x {25sin(5t)sin(t)} \, dt\\\\&=-5sin(5x)cos(x)+25cos(5x)sin(x)+ \int\limits^x {(25*5)sin(5t)sin(t)} \, dt\end{aligned}

And we can recognise the same integral, so.

\displaystyle (25-1)\int\limits^x {5sin(5t)sin(t)} \, dt= +5sin(5x)cos(x)-25cos(5x)sin(x)

And then,

\displaystyle \Large \boxed{\sf \bf\int\limits^x {5sin(5t)sin(t)} \, dt=\dfrac{5sin(5x)cos(x)-25cos(5x)sin(x)}{24}+C}

Thanks

If the volume of a cube is 1,728 cubic inches, find the side length of each of its sides.
krok68 [10]

Recall that the volume of a cube equals (side)^3. We can create an equation to model this.

1728 in^3 = (side)^3

We can get the cube root of both sides.

12 in = side

Each side is 12 inches long.

If the spinner is spun another 1000 times about how many times would you expect it to land on blue? Frequency of blue is 45
Veseljchak [2.6K]

Answer:

450 considering Blue appears 45 times in 100 spins.

Step-by-step explanation:

Let us assume that frequency of Blue is 45 times in 100 spins.

So we have to calculate the number of times the spinner lands on blue in 1000  spins.

It simply can be calculated as

Expected number of landing on blue:

Expected frequency = probability × number of trials

= (45/100)×1000

= 450 times

So, Expected number of landing on blue = 450
