I cant see what the numbers are but to find a cube, you do the number times itself 3 times example: 3 x 3 x 3 = 27. For cubing you do the number times itself twice for example 3 x 3 = 9.

I can see the square root though.
G: 36 = 6 64 = 8 81 = 9 25 = 5 324 = 18 529 = 23

The rest you should be able to understand with the explaining. Square root is finding what multiplied by itself is that number. Cube root is what times itself 3 times is that number. Hope this helps.

Find the 75th term: 88, 81, 74, 67, 60

oee [108]

Answer:

a₇₅ = - 430

Step-by-step explanation:

There is a common difference between consecutive terms, that is

d = 81 - 88 = 74 - 81 = 67 - 74 = 60 - 67 = - 7

This indicates the sequence is arithmetic with nth term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 88 and d = - 7 , then

a₇₅ = 88 + ( 74 × - 7) = 88 - 518 = - 430

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.
