Step-by-step explanation:
We have this function and let's derive it in terms of x.
y =x^2/In x
Dy/Dx=(x^2/In x)'=2/lnx *(x^2)'-(x^2/In x)'=> 2

Answer:
455 or 680, depending
Step-by-step explanation:
If we assume the three choices are different, then there are ...
15C3 = 15·14·13/(3·2·1) = 35·13 = 455
ways to make the pizza.
___
If two or three of the topping choices can be the same, then there are an additional ...
2(15C2) +15C1 = 2·105 +15 = 225
ways to make the pizza, for a total of ...
455 + 225 = 680
different types of pizza.
__
There is a factor of 2 attached to the number of choices of 2 toppings, because you can have double anchovies and tomato, or double tomato and anchovies, for example, when your choice of two toppings is anchovies and tomato.

Answer:
f(- 2) = - 1
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is

Answer:
Kimiya has 48 marbles, Ramneet has 12 marbles
Step-by-step explanation:
kimiya has 4x marbles ramneet has x marbles then 4x - 18 = x + 18 because if you give 18 marbles from kimiya to ramneet then you subtract 18 from kimiya and add 18 to ramneet by solving the equation you will get x as 12.So kimiya has 48 marbles, ramneet has 12 marbles.
