<h2>9 ft</h2>
Step-by-step explanation:
The height of kangaroo after it jumps is represented by the function 
, where 
is in seconds, height is in feet.
To find the maximum height that the kangaroo jumps, we need to maximise 
.
The minimum/maximum value of a quadratic expression 
is given by 
.
As the coeffecient of quadratic term is negative, the function has a maxima.
Maximum value = 
.
∴ Maximum height = 9 ft
Answer: 5 years
14,800 students enrolled
Step-by-step explanation:
Let x represent the number of years and
Let y represent the number of students enrolled
College A: y = 12,300 + 500x
College B: y = 18,550 - 750x
Use substitution Method to solve:
12,300 + 500x = 18,550 - 750x
+750x +750x
12,300 + 1250x = 18,550
-12,300 -12,300
1250x = 6250
x = 5
Input x = 5 into one of the equations to solve for y.
y = 12,300 + 500x
= 12,300 + 500(5)
= 12,300 + 2500
= 14,800
