Answer:
The value of the proportionality constant (y to x) is: 3/10
Step-by-step explanation:
We know the slope of any graph where 'y' varies directly with 'x' gives us the constant of proportionality 'k'.
i.e. y = kx
and k = y/x
Given the points
We know that the proportionality constant (y to x) is:
k = y/x
For the point (100, 30)
k = 30/100=3/10
For the point (300, 90)
k = 90/300=3/10
For the point (500, 150)
k = 150/500=3/10
As the value of proportionality constant (y to x) is the same.
i.e. k = 3/10
Thus, the value of the proportionality constant (y to x) is: 3/10
From my understanding and calculations I got the answer D “after the first year, there are 20 frogs”
Answer:
(a). (i) ; (ii) ; (iii); (iv)
(b).
Step-by-step explanation:
The formula you need to use is:
Then, in this case:
(a) Susbtituting values, we get:
(i)
(ii)
(iii)
(iv)
(b) Observe that as the time after 2 second gets smaller, the average velocity gets closer to . Therefpre, we can can estimate that the instantaneous velocity when is:
