What is Arithmetic Series

1 answer:

4 0

Answer:

I am pretty sure it is when you have a sequence of numbers that you are subtracting or adding from by the same constant over and over

Step-by-step explanation:

an=a1+(n-1)d

d=common difference

an= the nth term in the sequence

a1 first term in the sequence. (Usually you can plug in 1, as the n, and work from there)

How do I solve this? Please show work, thank you.

Answer:

a x sqrt(7) - 49sqrt(x)

Step-by-step explanation:

sqrt(7x) [ sqrt(x) - 7sqrt(7)]

Distribute

sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)

We know that sqrt(a) sqrt(b)= sqrt(ab)

sqrt(7x^2) - 7sqrt(7^2 *x)

Now lets separate out the perfect squares

sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)

x sqrt(7) - 7*7sqrt(x)

x sqrt(7) - 49sqrt(x)

Which of the following graphs could represent a cubic function?

Andru [333]

The answer would be graph (A)
The equation for this function is,
$f(x) = {x}^{3}$
Once you find different points around the graph it will end up looking like graph (A)

Hope this helped

Answer:

g ≤ 48

Step-by-step explanation:

Let g = # of guest

12.50(g) ≤ 600

$\frac{12.50g}{12.50} \leq \frac{600}{12.50}$

g ≤ 48
