Given:

Polygon

To find:

The sum of the interior angles of the polygon.

Solution:

Number of sides = 7

Sum of the interior angles formula:

$\text{Sum}=(n-2)\times 180^\circ$

Substitute n = 7 in the formula.

$=(7-2)\times 180^\circ$

$=5\times 180^\circ$

$=900^\circ$

The sum of the interior angles of the polygon is 900°.

Question 1 (1 point) Which equation can be represented by a graph with a vertex at (1,3)?

madam [21]

Answer:

See explanation

Step-by-step explanation:

You have not provided the options to help us give you a specific answer.

If a quadratic function is written in the form

$f(x) = a {(x - h)}^{2} + k$

Then (h,k) is the vertex, and 'a' is a constant.

For instance

$f(x) = 5 {(x - 1)}^{2} + 3$

has vertex at (2,3).

Also, an absolute function in the form

$g(x) = a |x - h| + k$

has vertex at (h,k).

This means

$g(x) = |x - 1| + 3$

also has vertex at (1,3).

I hope this explanation is helpful.
