Evaluate. Express your answer in exact simplest form.

kumpel [21]

Answer:

6720

Step-by-step explanation:

The writing 8P5 represents the number of permutations of 8 elements taken 5 at a time.

First Method :

8P5 = 8 × 7 × 6 × 5 × 4

= 6720

Second Method :

$8P5=\frac{8!}{\left( 8-5\right)!}$

$=\frac{8!}{ 3!}$

$=\frac{8 \times 7 \times 6 \times 5 \times 4 \times 3!}{ 3!}$

$= 8 \times 7 \times 6 \times 5 \times 4$

$= 6720$

What are the real zeros of the function g(x)=x^3+2x^2-x-2

Gre4nikov [31]

$g(x)=x^3+2x^2-x-2\\\\\text{The zeros:}\\\\g(x)=0\to x^3+2x^2-x-2=0\\\\x^2(x+2)-1(x+2)=0\\\\(x+2)(x^2-1)=0\iff x+2=0\ \vee\ x^2-1=0\\\\x+2=0\ \ \ |-2\\x=-2\\\\x^2-1=0\ \ \ |+1\\x^2=1\to x=\pm\sqrt{1}\to x=-1\ \vee\ x=1\\\\\text{Answer:}\ x=-2\ or\ x=-1\ or\ x=1$

Ali and Jake went on a cross-country

Helen [10]

Answer:

Let x = Kilometers by bus

then x + (x + 350) = 1100

2x = 750

x = 375 by bus

x - 350 + x = 1100

2x = 1450

x = 725 by train
