Answer:
6!=720
3! • 2!=12
Step-by-step explanation:
We must recall that the factorial of a number n (positive or zero) is the product of all the integers from n down to 1
n!= n(n-1)(n-2)...1
Let's evaluate the given expressions
6!=6\cdot 5\cdot 4\cdot 3\cdot 2\cdot 1=720
Similarly
3!\cdot 2!=(3\cdot 2\cdot 1)\cdot (2\cdot 1)=6\cdot 2=12
Finally
\displaystyle \frac{6!}{3!}=\frac{6\cdot 5\cdot 4\cdot 3\cdot 2\cdot 1}{3\cdot 2\cdot 1}
\displaystyle \frac{6!}{3!}= \frac{720}{6}=120
You have sold 72, and your friend has sold 74. Meaning your friend has sold 2 more magazine subscriptions than you.
2 divided by 47 so d....
Because they say fraction of this listed species are endangered plants
So you use total amount of endangered plant,2....and divide it by the total amount in the whole list 47
Answer:
Option D
The domain of the function is: {4, 7}
Step-by-step explanation:
We know that for polynomial functions like 
its domain and its rank are all real numbers. However, for this case we are told that the function range is: the set {25, 64}
This means that the function is bounded.
Then the domain of f(k) are all possible values of k such that f(k) belongs to the interval {25, 64}.
To find the limit values of k then we do f(k) = 25
Now we factor the expression:
Then k = 4 and k = -6.
Now we do f(k) = 64
We factor the expression:
k = -9 and k = 7.
Finally we search between the options given an interval that matches.
The option that matches is option D {4, 7}
