The unit rate of the parachutist change in height is 11 feet per second.
• In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .
• We use unitary method to find the ratio of one thing with respect to other thing.
• There are two types of unitary method one is Direct Variation and the other is Inverse variation.
We have the rate of descend as 44 feet in 4 sec.
So, in 1 second it will be = 44 / 4 = 11 feet.
Which is the unit rate.
Therefore, the unit rate of descend for the parachutist is 11 feet per second.

Answer: The next step will be 2x - 1 = 9
Step-by-step explanation:
4x -1 = 2x + 9
-2x -2x
2x -1 = 9
+1 +1
2x= 10
x= 5
MLN is an isosceles triangle
ML = MN
3x = x + 8
Subtract x from both sides
2x = 8
Divide both sides by 2
x = 4
MN = 4 + 8 = 12
