Answer:
(-1,2.5)
Step-by-step explanation:
Average rate of change = [H(100) - H(80)] / (100 - 80)
H(100) = 0.003(100)^2 + 0.07(100) - 0.027 = 0.003(10000) + 0.07(100) - 0.027 = 30 + 7 - 0.027 = 36.973
H(80) = 0.003(80)^2 + 0.07(80) - 0.027 = 0.003(6400) + 0.07(80) - 0.027 = 19.2 + 5.6 - 0.027 = 24.773
Average rate of change = (36.973 - 24.773)/(100 - 80) = 12.2/20 = 0.61
Answer: B
Answer: Then you picked (6,3) and there is nothing you can do about it
Answer:
k = 8
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 32 when x = 4, then
32 = 4k ( divide both sides by 4 )
8 = k
Answer:
the graph should be of the line y=5x
Step-by-step explanation:
the x axis should be labeled hours and the y axis should be labeled amount earned or dollars
the coordinates on the graph should be
(1,5) (2,10) (3,15) (4,20) (5,25) (6,30)
I cannot see the answer choices but I hope this information helps you answer the question
