Answer:
(7,4)
Step-by-step explanation:
Use the midpoint formula:
(x1+x2/2,y1+y2/2)
Sub in the points
9+5/2,2+6/2
7,4
Final answer:
(7,4)
Answer:
Suppose that the equations are:
The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.
N(T) = a0*r^(T)
Also, the number of people that leaves the park as the temperature increases are:
M(T) = a*T + b
So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:
N(T) - M(T) = total change in the park population as the temperature changes = C(T)
C(T) = a0*r^(T) - a*T - b
Multiplying a 1/4 times 12 gets you the same answer as 12 divided by 4
