I think the answer is 5 feet because 2(2+5)= 4+10=14. So the missing length is 5 feet.
Answer:
7000
Step-by-step explanation:
divide 600 and 30 then multiply that answer by 350
Answer:69
Step-by-step explanation:
69•2= 138
69-11=58
58•3=174
174+138=312
Lucas equation for his location is x(t) = 13t.
Alfonso's equation is x(t) = 238 - 21t
If you equate these, you get:
13t = 238 - 21t =>
34t = 238
t = 7
So after seven hours they meet.
Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:
![f(x)=A\cos (\frac{2\pi}{T}x)+b](https://tex.z-dn.net/?f=f%28x%29%3DA%5Ccos%20%28%5Cfrac%7B2%5Cpi%7D%7BT%7Dx%29%2Bb)
In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:
![\begin{gathered} f(x)=4\cos (\frac{2\pi}{\frac{3\pi}{4}}x)-3 \\ f(x)=4\cos (\frac{8}{3}x)-3 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%3D4%5Ccos%20%28%5Cfrac%7B2%5Cpi%7D%7B%5Cfrac%7B3%5Cpi%7D%7B4%7D%7Dx%29-3%20%5C%5C%20f%28x%29%3D4%5Ccos%20%28%5Cfrac%7B8%7D%7B3%7Dx%29-3%20%5Cend%7Bgathered%7D)
Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
