Step-by-step explanation:
f(x) = 2x^2 + 1
Let x= 3
f(3) = 2 * (3)^2 +1
Exponents first
= 2 * 9+1
Then multiply
= 18+1
Add
= 19

Answer:
$191
Step-by-step explanation:
The function is given by :
m(x) = 4.50x-7 ...(1)
Where
m(x) is the total cost if you buy x 12 packs of Mountain Dew.
We need to find the cost you pay to buy 44 12-packs of Mountain Dew
Put x = 44 in equation (1), we get :
m(x) = 4.50(44)-7
m(x) = 198-7
m(x) = $191
Hene, the cost for 44 12- packs of Mountain Dew is $191.
Answer:
43,680 ways.
Step-by-step explanation:
We have been given that an experiment involves 16 participants. From these, a group of 4 participants is to be tested under a special condition. We are asked to find the number of groups of 4 participants that can be chosen, assuming that the order in which the participants are chosen is irrelevant.
We will use permutations formula to solve our given problem.

For our given problem
and
.


Therefore, 4 participants can be chosen in 43,680 different ways.
