Which is greater 4 P 3 or 4 C 3?

Vladimir [108]

Answer:

$\large\boxed{_4P_3>_4C_3}$

Step-by-step explanation:

$\left\begin{array}{ccc}_nP_r=\dfrac{n!}{(n-r)!}\\\\_nC_r=\dfrac{n!}{r!(n-r)!}\end{array}\right\}\Rightarrow\dfrac{n!}{(n-r)!}>\dfrac{n^!}{r!(n-r)!}\Rightarrow_nP_r>_nC_r\\\\\text{because}\\-\text{the nominators are the same}\\-\text{the denominator}\ (n-r)!\ \text{is graeter than the denominator}\ r!(n-r)!$

$\text{Let's check our example:}\\\\n!=1\cdot2\cdot3\cdot4\cdot...\cdot n\\\\_4P_3=\dfrac{4!}{(4-3)!}=\dfrac{1\cdot2\cdot3\cdot4}{1!}=\dfrac{24}{1}=24\\\\_4C_3=\dfrac{4!}{3!(4-3)!}=\dfrac{1\cdot2\cdot3\cdot4}{1\cdot2\cdot3\cdot1!}=\dfrac{24}{6}=4\\\\24>4\Rightarrow_4P_3>_4C_3$

Solve the system of equations by substitution. X + y = 32 y = 7x The solution of the system is (Simplify your answer. Type an or

sweet-ann [11.9K]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

The given equations are :

$\qquad \sf \dashrightarrow \:x + y = 32$

and

$\qquad \sf \dashrightarrow \:y = 7x$

Now, plug in the value of y from equation 2 into equation 1 to find out the value of x ~

$\qquad \sf \dashrightarrow \:x + y = 32$

$\qquad \sf \dashrightarrow \:x + 7x = 32$

$\qquad \sf \dashrightarrow \:8x = 32$

$\qquad \sf \dashrightarrow \:x = 32 \div 8$

$\qquad \sf \dashrightarrow \:x = 4$

Now, plug the value of x in equation 2 to find y

$\qquad \sf \dashrightarrow \:y = 7x$

$\qquad \sf \dashrightarrow \:y = 7 \times 4$

$\qquad \sf \dashrightarrow \:y = 28$

Can someone please help. Will you graph the functions and approximate an x-value in which the exponential function surpasses the

MrMuchimi

The best way to solve this is to simply graph both functions in excel or on paper up to an x value of about10. I have done this in excel and can demonstrate that the exponential function surpasses the polynomial function at about x = 8. You can quickly prove this by substituting x = 8 into both equations. It is very apparent from the graph attached.
