50x+40=y for doors galore
40x+60=y for g&h
I can't graph here sorry but hopefully you know how that works
9. 40x+60=50x+40
-40
40x+20=50x
-40x
10x=20
x=2
10. Doors galore because 1 hours equates to 90 while g&h is 100 and so 90>100 then Doors galore is cheaper
thank you & if this helped pls don't forget to give brainiest
25 - 6 = 19 so 19 ft. it was 19 ft before he cleaned out the tank.
Answer:
75.245 or 75.25
Step-by-step explanation:
I assume your question amounts to finding the period of f(t)=8sin(4 pi t). A period L is a positive number such that f(t+L)=f(t) for all t. Since sin(x) is 2 pi perodic we can find the least number L such that 4pi(t+L)=4*pi*t+2*pi. Multiplying out we get
4pi(t+L)=4*pi*t+4*pi*L and we want to find L such that we get 4*pi*t+2*pi, notice if we take L=1/2 we get the desiered result 4*pi*t+4*pi*1/2=4*pi*t+2*pi. This proves that L=1/2 and your function has a period of 1/2.
