Simplify to an expression of the form (a sin(θ)).<br> 2sin(/8)2cos(/8)

rjkz [21]

Answer:

Your expression equals $2 \sin(\frac{\pi}{4})$ assuming the problem was to simplify $2\sin(\frac{\pi}{8}) 2\cos(\frac{\pi}{8})$ to the form $a\sin(\theta)$ .

Step-by-step explanation:

$2\sin(\frac{\pi}{8}) 2\cos(\frac{\pi}{8})$

$2(2)\sin(\frac{\pi}{8})\cos(\frac{\pi}{8})$

Let's use the following identity: $2\sin(A)\cos(A)=\sin(2A)$

$2\sin(2 \cdot \frac{\pi}{8})$

$2 \sin(\frac{\pi}{4})$ which is comparable to the form $a\sin(\theta)$ .

$a=2$

$\theta=\frac{\pi}{4}$

On a particular day, the wind added 2 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 2 miles

Lera25 [3.4K]

34= ( r + 4) * t
18 = ( r - 4) * t
solve for time in both equations
34/ (r + 4) = t
18 / (r - 4) = t
time is the same . so we can set them equal
34/ (r + 4) = 18 / (r - 4)

the answer is r = 13

HELP PLEASEEE<br> can someone help with number 9

Tasya [4]

Answer:

You would need more cubes because since the volume is decreased, you would need more cubes to fill up the original volume of 120 inches cubed. If the cubes were 2 inches, you would need 60. But if it was a half, you would need 240.
