Answer:
The given equation is:
f(m) = 3(1.09)^m
where 'f(m)' represents the length of the fish after 'm' months.
Domain is considered as a set of all values of input. In this question, the input is number of months. The input should starts at 0 which will show the initial height and then as the number 'm' increases, the value of f(m) also increases.
Thus, the domain can be defined as m ≥ 0
y-intercept occurs at m=0. It means the height of the fish after 0 months, which can also be considered as initial height.
Calculate the value of function for m=2 and m=8
For m=2, f(2) = 3.564
For m=8, f(8) = 5.978
Average rate of change = (5.978-3.564) / (8-2)
Average rate of change = 0.402
It means the fish grows about 0.402cm each month in between 2 to 8 months
Answer:
Step-by-step explanation:
We know that £1 equals 100p.
Knowing this relation, we can use the rule of three
Then, we form the fraction
Therefore, the fraction of of £3.00 is
(1 3/4) / (3/4) = x / 1.....1 3/4 miles to 3/4 hrs = x miles to 1 hr
cross multiply
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = 7/4 * 4/3
x = 28/12
x = 2 1/3 miles in 1 hr <==
