Step-by-step explanation:
i just put 600 times 0.722^x=2 in desmos graph and got that
Okay so if he serves 18 customers in 42 minutes divide 18 by 42 and you get the amount of customers he serves per min which is 0.42857413 then multiply that by 120 since 2 hours add up to 120 minutes and you get 51.43
Answer:
30°
Step-by-step explanation:
The ratio of the side opposite (AB) to the hypotenuse (AC) is ...
4.5/9 = 1/2
From your memory of a short table of trig functions you know this is the sine of 30°. From the mnemonic SOH CAH TOA, you know that
Sin = Opposite/Hypotenuse
Putting these facts together gets you ...
sin(C) = 1/2 = sin(30°)
C = 30°
