Answer:
(a) 5440.42 g
Step-by-step explanation:
The amount remaining (Q) is given in terms of the initial amount (Q₀) by the exponential decay formula ...
Q = Q₀(1/2)^(t/330) . . . . . where t is in days
__
The amount after 540 days is ...
1750 g = Q₀(1/2)^(540/330) = 0.321666Q₀
Q₀ = (1750 g)/(0.321666) ≈ 5440.42 g
The initial quantity was about 5440.42 grams.
Rate of change=R∆=(y2-y1)/(x2-x1)=∆y/∆x
(X1,Y1)(X2,Y2)
(1,2)(2,4)
R∆=∆y/∆x
=(4-2)/(2-1)
R∆=2
(2,4)(3,8)
R∆=(8-4)/(3-2)
R∆=4
(3,8)(4,16)
R∆=(16-8)/(4-3)
R∆=8
The ramp is modelled as shown in the diagram below.
The angle of elevation from the car is the angle form by the horizontal line and the observer eye from the car. In the diagram, this angle is marked by
