Evaluate 4!7! divided by 6!8!

Mathematics
1 answer:
faltersainse [42]4 years ago
4 0
! is factorial
it means multipliy all numbers from 1 to that number together
example
1!=1
2!=2*1
3!=3*2*1
etc

some things to note
7!*8=8!
4!*5*6=6!


\frac{(4!)(7!)}{(6!)(8!)}
so we can rewrite it as
\frac{(4!)(7!)}{(4!)(5)(6)(7!)(8)}=
\frac{1}{(5)(6)(8)}=
\frac{1}{240}

What problem or problems could we potentially run into if we use graphs to find the exact roots
Nookie1986 [14]

The possible problems  of using graphs to find roots are:

  • Having complex roots.
  • Having irrational roots.

<h3>How to find the roots of a quadratic function with a graph?</h3>

First, the roots of a quadratic function are the values of x such that:

a*x^2 + b*x + c = 0

To find the roots using a graph, we need to see at which values of x does the graph of the parabola intercepts the horizontal axis.

<h3>What are the possible problems with this method?</h3>

There are two, the first one is having irrational roots, in that case, an analytical or numerical approach will give us a better estimation of the roots. Finding irrational values by looking at the intercepts of the graph can be really hard, so in these cases using the graph to find the roots is not the best option.

The other problem is if we <u>don't have real roots</u>, this means that the graph never does intercept the horizontal axis. In these cases, we have complex roots, that only can be obtained if we solve the problem analytically.

Which orders paid is a solution is the equation y= 4x + 9
Verizon [17]

<em>Note: you did not add the answer options, so I am solving this question generally to solve your query, which anyways would clear your concept.</em>

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y= 4x + 9

All we need is to find any random value of 'x' and then solve for 'y'.

For example, putting x=2

y= 4x + 9

y=4(2)+9

y=8+9

y=17

Thus, (2, 17) is one of the many ordered pairs solutions of the equation.

Similarly, putting x=3

y= 4x + 9

y=4(3)+9

y=12+9

y=21

Thus, (3, 21) is one of the many ordered pairs solutions of the equation.

three consecutive integers can be represented by n, n+1 and n+2. if the sum of three consecutive integers is 57 what are the int
Paul [167]

18,19 and 20 are the integers.

Step-by-step explanation:

Given three integers are;

n, n+1, n+2

According to given statement;

n+(n+1)+(n+2)=57

n+n+1+n+2=57\\3n+3=57\\3n=57-3\\3n=54\\Dividing\ both\ sides\ by\ 3\\\frac{3n}{3}=\frac{54}{3}\\n=18

n=18

n+1 = 18+1 = 19

n+2 = 18+2 = 20

18,19 and 20 are the integers.
