Answer:111
the purse was 1/4 so. we have to do
37.00x4 we get 148 then. we do 148-37 to get a total of 111 (:
Step-by-step explanation:
Answer:
Possible answers could be that you have 400 adults and no children, or you could have 100 children and 340 adults.
If we just have
![y = \cos x](https://tex.z-dn.net/?f=y%20%3D%20%5Ccos%20x)
that's an amplitude of 1 and a period of ![2\pi](https://tex.z-dn.net/?f=2%5Cpi)
Let's modify this step by step.
Amplitude of 4. Four times the amplitude means a factor of 4 on the outside.
![y = 4 \cos x](https://tex.z-dn.net/?f=y%20%3D%204%20%5Ccos%20x)
Period of π. Double the period means a factor of 2 on the inside.
![y = 4 \cos(2x)](https://tex.z-dn.net/?f=y%20%3D%204%20%5Ccos%282x%29)
Horizontal shift of π/2 to the left. To the left means adding a positive number to x. The question appear ambiguous. It's not clear to me if we add to x or 2x; let's make it
![y = 4 \cos(2(x + \frac \pi 2))](https://tex.z-dn.net/?f=y%20%3D%204%20%5Ccos%282%28x%20%2B%20%5Cfrac%20%5Cpi%202%29%29)
Vertical shift of 3:
![y = 3 + 4 \cos(2(x + \frac \pi 2))](https://tex.z-dn.net/?f=y%20%3D%203%20%2B%204%20%5Ccos%282%28x%20%2B%20%5Cfrac%20%5Cpi%202%29%29)
![y = 3 + 4 \cos(2x + \pi)](https://tex.z-dn.net/?f=y%20%3D%203%20%2B%204%20%5Ccos%282x%20%2B%20%20%5Cpi%29)
Depending on the interpretation of the phase shift, that pi may be a pi/2.
Answer: ![3 + 4 \cos(2x + \pi)](https://tex.z-dn.net/?f=3%20%2B%204%20%5Ccos%282x%20%2B%20%20%5Cpi%29)
The right answer is Nine.
Answer:
5040
Step-by-step explanation:
-1 × -2 × -3 × -4 × -5 × -6 × -7 × -8 = 40320
40320 ÷ 8 = 5040
(not 100% sure this is right)
