Find all the values of x where the tangent line is horizontal.<br> 2x^3+36x^2+192x+12

Afina-wow [57]

At x = -4 and -8
Take the derivative of the given equation to find rate of change of the graph.
f'(x) = 6x^2 + 72x + 192
At a horizontal tangent, f'(x) = 0, so set the equation equal to 0 and solve. Eventually you get x = -4 and -8

6. a) Rivka used the last four digits of her

bulgar [2K]

Answer: Her e-mail password is $1048222131$

Step-by-step explanation:

You know that a part of Rivka's e-mail password is formed by the last four digits of her telephone number.

The exercise gives you the last four digits of Rivka's telephone number:

$1048$

Now, in order to find the other numbers, you need to descompose $1048$ into its prime factors. Then:

$1048=2*2*2*131$

Therefore, based on this, you can determine that her e-mail password is:

$e-mail\ password=1048222131$
