Since the rate is constant, the growth of the height of the helicopter follows a linear pattern. The helicopter has an initial quota of 40ft, so that would be the constant term. The linear terms's coefficient is the rate of growth, so 21 ft/s. So, if is the number of seconds passed from when the observation started, we have
Which means that, if , the height is
Let's solve for x the following question:
3/4 (x - 16) = 5/4 (2x - 32)
As I told you on the previous exercise:
Step 1: Solve the parenthesis
3/4 x - 48/4 = 10/4 x - 160/4
Step 2: Like terms
3/4x - 10/4x = -160/4 + 48/4
-7/4x = -112/4
Step 3: Simplifying
-7/4x = -28
Step 4: Multiplying by 4 at both sides:
-7/4x * 4 = -28 * 4
-7x = -112
-7x/-7 = -112/-7
x = 16
Answer:
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.

Answer:
<em>is the increased number.</em>
Step-by-step explanation:
<em>The first step would be to turn the percentage into a decimal. To do that, divide it by 100.</em>
Then, multiply that by 90.
Add both together to get the increased price.
