Answer:
A. Every minute, 2/3 of a gallon is drained, so the rate of change would be -2/3
B. It would take 7.5 minutes to drain the tank
Answer:
D. sin J = Cos L
Step-by-step explanation:
LK = √219² - 178² = 127.58
sin J = <u>LK/LJ</u> =127.58/219 = 0.58
Cos L = <u>Lk/LJ</u> = 0.58
sin L = 178/219 = 0.81
Cos J = 178/219 = 0.81
Tan J = 127.58/178 = 0.72
tan L = 178/127.58 = 1.40
He would be able to make 4 servings out of it:
