The explicit rule is an = a1 + 12 * (n - 1).

From the recursive rule, we can tell that each term is 12 more than the previous term, so we can write a1 + 12 * n.

However, if that's the rule, then when a1 is plugged in, it doesn't work. So, we must do 12 * (n - 1) to make it work.

Therefore, the explicit rule is:

an = a1 + 12 * (n - 1).

In terms of x? pls solve and show your work! Will give u brainliest!

weeeeeb [17]

Answer:

$\sqrt{ {x}^{2} - 1 }$

Solution,

base=1

perpendicular=?

hypotenuse=X

now,

using Pythagoras theorem,

x^2=p^2+b^2

or, x^2=p^2+1^2

or,p^2=x^2-1

or, p=√x^2-1

tan theta=perpendicular/ base

tan theta =√x^2-1/1

tan theta=√x^2-1

z=tan theta

z=√x^2-1

Hope this helps...

Good luck on your assignment..

If f(x) = 3x - 1 and g(x) = x + 2, find (f+ g)(x).

Volgvan

Answer:

4x+1

Step-by-step explanation:

Since you're finding (f+g) (x), it means you are adding f(x) and g(x) together.

so you add: (3x-1) and (x+2)

combining like terms, you get 4x and 1, which means (f+g)(x)= 4x+1
