The exponential equation represents an exponential growth because the rate of decay is 1.02 which is greater than 1.
y = 90(1.02)^x
The general form equation is:
y(x)= a(1+r)^x such that r is the decay percent.
on comparing,
1 + r = 1.02
r = 1.02 - 1
r = 0.02
converting into percent
r = 0.02 * 100
r = 2%.
Hence the exponential growth is 2%.

Answer:
25
Step-by-step explanation:
Using the rules of BIDMAS, you first work out the calculation inside the bracket. y-z equals 25-20 which equals 5. then, you work out out the fraction. x=10 so 10/2 equals 5. Then, multiply the value inside the bracket (5) by the outside value(5). This equals 25
This is the concept of combination, the number of ways 4 different color can be chosen from 9 different colors will be:
9C4
=(9!)/(4!(9-4)!)
=362,880/(24×120)
=362,880/2880
=126
thus the number of ways is 126 ways

Answer:
Increasing
Step-by-step explanation:
Let's see what happens if we choose a value for b greater than 1.
Let's try b=2.
.
I'm going to keep increasing x. If y increases, the the function is increasing. If y decreases, the function is decreasing.
Let's start with x=1.
Now x=2.
The y's got higher as you increased x so the function is increasing.
