Answer:

The answer is 16xy

Step-by-step explanation:

All we have to do is take out the x and the y then multiply.

2 * 4 * 2 = 16

Then we add the x and y back.

= 16xy

So, the answer is 16xy

Hope this helps! :)

A pirate shoots a cannonball into the air from a height of 10
Aneli [31]

We are basically given most of what we need to calculate the height of the cannonball.

We use the formula h = –16t+ vt + s to find the height requested.

Let v = 160

Let s = 10

Let t = time in seconds

Was the value of t included? We need to know t to plug into our formula.

You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.

Help I can't find the answer
Bond [772]

For angles \theta between 0º and 90º, we know \sin\theta and \cos\theta are both positive.

Then \frac\theta2 falls between 0º and 45º, so both \sin\frac\theta2 and \cos\frac\theta2 are also positive.

Recall the double angle identities,

\sin^2x=\dfrac{1-\cos2x}2\implies\sin^2\dfrac\theta2=\dfrac{1-\cos\theta}2

\cos^2x=\dfrac{1+\cos2x}2\implies\cos^2\dfrac\theta2=\dfrac{1+\cos\theta}2

We know sine and cosine should be positive, so taking the square root of both sides gives us

\sin\dfrac\theta2=\sqrt{\dfrac{1-\cos\theta}2}

\cos\dfrac\theta2=\sqrt{\dfrac{1+\cos\theta}2}

Also recall the Pythagorean identity,

\cos^2x=1-\sin^2x\implies\cos\theta=\sqrt{1-\sin^2\theta}

Then

\cos\theta=\sqrt{1-\left(\dfrac27\right)^2}=\dfrac{3\sqrt5}7

and from here we get

\sin\dfrac\theta2=\sqrt{\dfrac{7-3\sqrt5}{14}}

\cos\dfrac\theta2=\sqrt{\dfrac{7+3\sqrt5}{14}}
