Mathematics
1 answer:
irina [24]3 years ago
4 0

Answer:

<em>x = 5</em>

Step-by-step explanation:

5(x + 4) - 8 = x + 32

5x + 20 - 8 = x + 32

5x + 12 = x + 32

5x - x + 12 = 32

5x - x = 32 - 12

4x = 32 - 12

4x = 20

x = 5

Hope this helped! :)

Evaluate the expression. StartFraction 9 factorial Over 3 factorial EndFraction 3 6 60,480 362,874
REY [17]

Answer:

60,480 is the correct answer.

Step-by-step explanation:

First of all, let us have a look at the <em>formula of factorial of a number 'n'</em>:

n! = n \times (n-1) \times (n-2) \times ...... \times 1

i.e. multiply n with (n-1) then by (n-2) upto 1.

<em>Keep on subtracting 1 from the number and keep on multiplying until we reach to 1.</em>

<em></em>

So, 9! can be written as: 9 \times 8 \times 7 \times ...... \times 1

Similarly 3! can be written as: 3 \times 2 \times 1

Re-writing 9 ! :

9 \times 8 \times 7 \times ...... 3 \times 2 \times 1\\\Rightarrow 9 \times 8 \times 7 \times ...... 3 !

Now, the expression to be evaluated:

\dfrac{9!}{3!} = \dfrac{9 \times 8 \times 7 \times ..... \times 3!}{3!}\\\Rightarrow 9 \times 8 \times 7 \times 6 \times 5 \times 4\\\Rightarrow 60480

Here is a graph of the function y, both continuous and differentiable. For approximately what values of x between -5 and 5 is th
Law Incorporation [45]
From the graph you can determine the first derivative by looking at the turning points. These are where the first derivative is zero.

y' = x(x-2)(x+2)(x-5)(x+5) \\  \\ y' = x^5 -29x^3 +100x

Take derivative to get 2nd derivative and set equal to zero:
y'' = 5x^4 -87x^2 +100 = 0

Solve for x:
x^2 = \frac{87 \pm \sqrt{87^2 -2000}}{10} \\  \\ x = \pm 1.11, \pm 4.02
