Answer:
The exponential function will be
Step-by-step explanation:
Let the exponential function is given by ............ (1)
Now, ordered pairs (2,20) and (3,40) are the solution of the above exponential function. So, they will satisfy the equation.
Now, for the ordered pair (2,20) putting f(2) = 20, we get
............. (2)
Again, for the ordered pair (3,40) putting f(3) = 40, we get
............. (3)
Now, from equations (3) and equation (2) we get,
2 = b
⇒ b = 2.
Now, from equation (2) we get,
⇒ a = 5
Therefore, the exponential function will be

Answer:
The answer is D. Selections of objects in which the order of the objects matters.
Step-by-step explanation:
Permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement.
The formula for permutation: A permutation is the choice of (r) things from a set of (n) things without replacement and where the order matters. Formula-
Permutation can be classified in three different categories:
- Permutation of (n) different objects (when repetition is not allowed)
- Repetition, where repetition is allowed
- Permutation when the objects are not distinct (Permutation of multi sets)
