D because for a sequence you can't have a -1st term so b is out and a and c mean the same thing so neither of them can be the answer

Answer: All integers where n ≥ 1

Step-by-step explanation:

We know that the domain of any sequence is the set of natural numbers $\mathbb{N}$ .

Therefore, the domain for the given arithmetic sequence $a_n=-5+3(n-1)$ is the set of natural numbers.

Since we know that the set of natural numbers starts with digit 1.

Therefore, the domain of the given arithmetic sequence is all integers where n≥1.

Answer:

D) 5/2

Step-by-step explanation:

(3, –1) and (5, 4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4 + 1)/(5 - 3)

m= 5/2

Can someone show me way of solving this

erma4kov [3.2K]

Step-by-step explanation:

$f(x) = ln( \frac{1}{x} )$

To find the derivative, notice we have a function 1/x inside of another function, ln(x)

We use what we call the chain rule,

It states that

derivative of a '

$\frac{d}{dx} f(g(x)) = f '(g(x)) \times \: g '(x)$

Here f is ln(x)

f is 1/x

So first, we know that

$\frac{d}{dx} ( ln(x) = \frac{1}{x}$

$f'(g(x)) = \frac{1}{ \frac{1}{x} }$

We know that

$g'(x) = - \frac{1}{ {x}^{2} }$

So we have

$x \times - \frac{1}{ {x}^{2} } = \frac{ - 1}{x}$

How to Break apart 3x7

stiv31 [10]

Well brake 7 into 5 and 2 and then just multiply it by 3 so it would be 5 x3=15 and 2x3=6 then u add 15+6 it would be the sum, of 21 so 3x7=21
