You have
.. f'(u) = sec(u)^2
Putting in u = g(x) = x^9, this becomes
.. f'(g(x)) = sec(x^9)^2

You know
(f(g(x))' = f'(g(x))*g'(x) . . . . . chain rule
From previous results, this is
.. sec(x^9)^2*9x^8

Answer: C

Step-by-step explanation: If this is drawn to scale, 12 15 and 30 make absolutely no sense, because if you multiply any of those numbers by 5 your gonna get a number bigger than 60.

Therefore, 6 is the answer

What is the length of CD to the nearest 10th?

Snezhnost [94]

Answer:

$\huge \boxed{\mathrm{10.3 \ units}}$

Step-by-step explanation:

To solve for <em>CD</em>, we can create a right triangle.

Where <em>CD</em> becomes the hypotenuse.

The length of the base of the triangle is 9 units.

The length of the height of the triangle is 5 units.

Apply Pythagorean theorem to solve for the hypotenuse.

$\sf hypotenuse = \sqrt{(base )^2 +(height )^2 }$

$c=\sqrt{9^2 +5^2 }$

$c=\sqrt{106}$

$c \approx 10.29$

Answer:

(x-10)(x+10)

Step-by-step explanation:

x^2 – 100

This is the difference of squares

x^2 - 10^2

We know that (a^2 - b^2) = (a-b) (a+b)

(x-10)(x+10)
