Answer:
C(x,y) = (-28,13)
Step-by-step explanation:
If co-ordinates of points A(x1,y1) and (x2,y2) and C is the external point that divides the line AB in ratio m:n then,
Given: A (-6, 3) & B (5, -2) in ratio 2 : 3
Substituting these values in above formula to C(x,y)
C (x,y) = \frac{2\times5-3(-6)}{2-3} , \frac{2(-2)-3(3)}{2-3}
Solving we get
C(x,y) = (-28,13)
Answer:
initial value is 15
growth factor is 1.25
Step-by-step explanation:
we are given
The number of members f(x) in Joe's health club
increased by 25% every year over a period of x years
The function below shows the relationship between f(x) and x as
now, we can compare it with exponential function
where
a is the initial value
b is growth factor
we can compare and find 'a' and 'b'
So,
initial value is 15
growth factor is 1.25
we know that
x is time
so, it can never be negative
f(x) is number of chambers
so, f(x) can not be negative
now, we can draw graph
and we get as
