Answer:

recursive: f(0) = 7; f(n) = f(n-1) -8

explicit: f(n) = 7 -8n

Step-by-step explanation:

The sequence is an arithmetic sequence with first term 7 and common difference -8. Since you're numbering the terms starting with n=0, the generic case will be ...

recursive: f(0) = first term; f(n) = f(n-1) + common difference

explicit: f(n) = first term + n·(common difference)

To get the answer above, fill in the first term and common difference values.

What is the sum of the interior angles

galben [10]

Answer:

The sum of the interior angle is 108°

Step-by-step explanation:

To find the sum of the interior angle, you need this equation:

$\frac{180(n-2)}{n}$ (The variable $n$ represents the number of sides does a shape have).

-Count the sides of the shape:

The following polygon shown, has 5 sides.

-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:

$\frac{180(5-2)}{5}$

-Then, you solve:

$\frac{180(5-2)}{5}$

$\frac{180(3)}{5}$

$\frac{540}{5} = 108\textdegree$

So, the sum of the interior angle is $108\textdegree$ .

Which expressions are equivalent to ? Check all that apply.

GrogVix [38]

Answer:

6.2+8.7+8.9x

Step-by-step explanation:

For expressions to be equivalent, they must simplify to the same lowest form. 8.9x+6.2+8.7 simplifies to 8.9x +14.9.

Each of the expressions below must simplify to 8.9x + 14.9 to be equivalent.

9x+6+9 = 9x + 15 NO

3.9+6.2+8.7x = 8.7x + 10.1 NO

3.7+8.9+6.2 = 18.8 NO

6.2+8.7+8.9 = 23.8 NO

6.2+8.7+8.9x = 8.9x + 14.9 YES

3.9+6.2x+8.7 = 6.2x + 12.6 NO

3.9x+8.7+6.2 = 3.9x + 14.9 NO
