Answer:
B
y = 3 cos (pi/12x - pi/4) + 17
Step-by-step explanation:
First find the average temperature which is 20 + 14/2 = 17
Find the amplitude
20 - 17 = 3
This means that that at noon, the shift is 3hrs past
the best equation that represents this scenario is ![y = 3 cos (\frac{\pi}{12}x - \frac{\pi}{4}) + 17](https://tex.z-dn.net/?f=y%20%3D%203%20cos%20%28%5Cfrac%7B%5Cpi%7D%7B12%7Dx%20-%20%5Cfrac%7B%5Cpi%7D%7B4%7D%29%20%2B%2017)
Answer:
x=1.25, y=2.5
Step-by-step explanation:
x = # of soft tacos
y = # of double deckers
3x+3y=11.25 *4 => 12x+12y=45
4x+2y=10 *-3 =>-12x-6y=-30
6y=15
y=2.5
4x+2(2.5)=10
4x+5=10
4x=5
x=1.25
Answer:
120x4
Step-by-step explanation:
11x10=110cm^3 You simply multiply the base with length, thus answer is 110cm^3
