Find all solutions in the interval [0, 2π). (sin x)(cos x) = 0

Deffense [45]

$\bf sin(x)cos(x)=0\implies 
\begin{cases}
sin(x)=0\\
\measuredangle x=sin^{-1}(0)\\
\measuredangle x=0\ ,\ \pi \\
----------\\
cos(x)=0\\
\measuredangle x=cos^{-1}(0)\\
\measuredangle x=\frac{\pi }{2}\ ,\ \frac{3\pi }{2}
\end{cases}$

Explain how you would convert a measurement given in ounces into pints

Greeley [361]

8 ounces = 1cup
2 cups = 1 pint
So, 16 ounces = 2 cups = 1pint
16 ounces = 1 pint

If you have 8 ounces, you would have half a pint.
If you have 20 ounces:
20 ounces/16 ounces= 5/4
So, you'd have 1 1/4 or 1.25 pints

Quick I need to finish this and I still have more questions after

OLEGan [10]

Answer:

$1\frac{1}{2}$ or 1.5

Step-by-step explanation:

Now we know it's a dilation. So we can use any two points. I chose V and V'.

V: (3,6)

V': (2,4)

So how we get from 6 to 4?

$4(x)=6\\x=\frac{6}{4} \\x=1.5$

You can tell it's 1.5 aswell because 4 times 1 is 4 and 4 times 0.5 is 2. Add them to get 6.

Therefore, the dilation factor is 1.5.
