Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction
21.192 can be written as 21 192/1000 so yes its rational
i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.
Hope this helps :P
Answer:
The slope also increases
Step-by-step explanation:
The slope of a function is the ratio of change in y to change in x. For an exponential function f(x) = e^x, the slope of the function is equal to the function, i.e slope = e^x.
For a function represented by 
, this is an exponential function representing growth, the slope of is also 
, therefore as the value of x increases, the value of the slope also increases.
At x = 1, slope = 2^1 = 2, At x = 4, slope = 2^4 = 16.
1. Elena’s mistake is that she should have put x as 500.
2. Elena’s inequality should be 55.25x is less than or equal to 500. 55.25 represents how much gigabytes 1 movie takes up. 500 is the amount of gigabytes she is able to have. X is the amount of songs she can have.
Number of Good Oranges = 2/3 * 48 = 32
Now, Let the number of Oranges taken by David = x
Taken by Ben = x + 8
It is given that, x + x+8 = 32
2x = 32 - 8
x = 24/2
x = 12
In short, David takes 12 Oranges

That would be 2.1 because if it's in decimal it's 2.1
