15.87 or 15.8 that’s from me finding the square root if that helps any
For this case we have a function of the form:
![y = A * (b) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%20A%20%2A%20%28b%29%20%5E%20x%20%20)
Where,
A: amount or initial value
b: rate of change
x: independent variable
y: dependent variable
We have two possible cases:
If 0 <b <1:
The exponential function is decreasing
if b> 1:
the exponential function is increasing.
For this case we have the following function:
![f (x) = 7.2 * (1.08) ^ x](https://tex.z-dn.net/?f=%20f%20%28x%29%20%3D%207.2%20%2A%20%281.08%29%20%5E%20x%20%20)
For this case we have to:
![b = 1.08](https://tex.z-dn.net/?f=%20b%20%3D%201.08%20%20)
Therefore, the exponential function is increasing.
The percentage of growth is:
![(1.08-1) * (100) = 8%](https://tex.z-dn.net/?f=%20%281.08-1%29%20%2A%20%28100%29%20%3D%208%25%20%20)
Answer:
The exponential function is increasing.
The exponential function grows 8% for each value of x.
Answer:
a) 2048
b)164
c)54
d) 11
Step-by-step explanation:
a) A coin has two faces.
Outcome possible =2^11= 2048
b) 8 heads possible outcome = 11!/8!3! = 3971688/241/920= 164 ways
c)2 heads outcome= 11!/2!8!= 39716800/725760=54
d) 7 heads= 11!/7!6! =39716800/3628800 = 11
Answer:
10
