Answer:
<h3>Rational number</h3>
Step-by-step explanation:
A rational number are number that can be written as the ratio of two integers. Integers are whole numbers and they can be positive or negative including zero.
Looking at the value 5.371, we can write it in fraction form as shown;
5.371 = 5371/1000
Since 5.371 is equivalent to 5371/1000 and <em>5371/1000 is a ratio of two integers 5371 and 1000 therefore we can conclude that 5.731 is a rational number</em>
<u>Note that decimal numbers are not integers and are not whole numbers.</u>
Answer: x = (1,9]
Step-by-step explanation: If x is all real numbers greater than 1 (simply: x is greater but not equal to 1) then it is 1 < x. And if x is less than or equal to 9 then its x ≤ 9. To translate 1 < x ≤ 9 into interval notation, you need to keep in mind that parentheses are for these symbols: <>. And brackets are for these symbols: ≤≥. With that in mind, your answer is (1,9]. Also, keep in mind that interval notation goes from lowest value number to highest, so you wouldn’t write this notation as [9,1).
Answer:
4,486.93 ft
Step-by-step explanation:
Let 'h' be the height of the mountain and 'x' be the horizontal distance between the first position measured and the top of the mountain.
Two right triangles can be modeled such that their tangent relationships yield:

Solving the linear system:

The mountain is 4,486.93 ft high.
The answer appears to be A.
Answer:
<u>Line b</u>
Step-by-step explanation:
It cannot be line a or line d because the line will have a constant rate of change. It cannot be line c because line c would be undifined. Therefore, it must be line b.
