Distribute the 9 to each term in the parentheses with multiplication.

9(3 + x) = 27 + x

But this is usually written as x + 27

Find the slope of the graph of the equation at the given point. (If an answer is undefined, enter UNDEFINED.)

juin [17]

Answer:

Undefined.

Step-by-step explanation:

We want to find the slope of the graph of the equation:

$\displaystyle x^2 - y^2 = 81$

At the point (9, 0).

In other words, we want to evaluate dy/dx when x = 9 and y = 0.

Find dy/dx. We can take the derivative of both sides with respect to x:

$\displaystyle \begin{aligned} \frac{d}{dx}\left[ x^2 - y^2\right] = \frac{d}{dx}\left [ 81\right] \\ \\ 2x - 2y \frac{dy}{dx} &= 0 \\ \\ \frac{dy}{dx} = \frac{x}{y}\end{aligned}$

Then the slope of the graph at the point (9, 0) will be:

$\displaystyle \begin{aligned} \frac{dy}{dx}\Big|_{(9, 0)} &= \frac{(9)}{(0)} \\ \\ &= \text{Und.}\end{aligned}$

In conclusion, the slope of the graph at the point (9, 0) is undefined.

Find the volume of given solid.plz give explaination.

lara31 [8.8K]

Answer:

480 cm^3

Step-by-step explanation:

Total volume is the sum of the volumes of the 3 cuboids.

Cuboid at the bottom:

V = l×b×h

V = 12 × 5 × 4 = 240

Both on top are identical.

Their height is 10-4= 6 cm

Each has volume = 5×4×6 = 120

Total Volume = 240 + 120 + 120

= 480 cm^3
