Answer:
x represents the number of weeks of growth.
Step-by-step explanation:
Given:
We are given a models the length (cm) of a lizard each week from beginning of the lizards life.
f(x) represents the length of lizards after x week
x represents the number of weeks from beginning.
Because it is a exponential growth function
where,
If b>0 then growth
If 0<b<1 then decay
x represents the time of decay or growth.
So, In the given equation x represents number of weeks of growth because b=1.24 >1
Given parameters:
Midpoint of AB = M(3, -1)
Coordinates of A = (5,1)
Unknown:
Coordinates of B = ?
Solution:
To find the mid point of any line, we use the expression below;
and
where and
= coordinates of the mid points = 3 and -1
x₁ = 5 and y₁ = 1
x₂ = ? and y₂ = ?
Now let us input the variables and solve,
3 = and -1 =
5 + x₂ = 6 -2 = 1 + y₂
x₂ = 1 y₂ = -2 -1 = -3
The coordinates of B = 1, -3
