Answer:
<h3>Rational numbers</h3>
Step-by-step explanation:
A rational number is a number that can be written as a ratio of two integers. The are expressed as fractions. Given the value 8/9, this value is a fraction and is written as a ratio of two integers 8 and 9.
The value is neither a real number, nor an integer because integers and whole numbers are not expressed as fractions.
Natural numbers are also whole numbers starting from 1 and above. Hence 8/9 is not a natural number as well.
Note that irrational numbers are also classified as real numbers and they can not be written as a ratio of two integers.
Conclusively, 8/9 is only classified as a rational number
The answer is r=16 you have to square everything
Answer:
X^5+3x^4+81x+ 243
Step by step:
X^4*x=x^5
X^4*3=3x^4
81*x=81x
81*3=243
Answer:
![f(x)=0.7(5)^x](https://tex.z-dn.net/?f=f%28x%29%3D0.7%285%29%5Ex)
Step-by-step explanation:
![\text{Exponential function: }y=a\cdot b^x](https://tex.z-dn.net/?f=%5Ctext%7BExponential%20function%3A%20%7Dy%3Da%5Ccdot%20b%5Ex)
It is two types of function.
- Exponential Growth: If function increase as value of x increase.
In this case, a>0 and b>1
- Exponential decay: If function decrease as value of x increase.
In this case, a>0 and 0<b<1
We need to choose exponential growth function.
![\text{Exponential Growth function: }f(x)=0.7(5)^x](https://tex.z-dn.net/?f=%5Ctext%7BExponential%20Growth%20function%3A%20%7Df%28x%29%3D0.7%285%29%5Ex)
Here a=0.75>0 and b=5>1
Therefore, This function is exponential growth.
