Answer:

The central angle is 330 degrees

Step-by-step explanation:

The arc length is equal to the circumference time the fractional part of the circle

arc length = circumference * x/360

11 = 12 * x/360

Divide each side by 12

11/12 = 12/12 *x/360

11/12 = x/360

Multiply by 360

11*360/12 = x /360 *360

330 = x

The central angle is 330 degrees

Which function is graphed on the right?

Norma-Jean [14]

Answer: $y=2^{x-2}+3$

Step-by-step explanation:

To find the equation from a graphed function, you can substitute points into each equation to find the original:

A point on the graph is (2, 4). Substituting this into each equation, we get:

$4=2^{2+3} -2$ , which claims that 4 is equal to 30, which is incorrect.

$4=2^{2-3} +2$ , which claims that 4 is equal to 3/2, which is incorrect.

$4=2^{2-2}+3$ , which claims that 4 is equal to 4, which is correct.

We can test the third function further by taking another point on the graph, (3, 5), and substituting it into the function:

$5=2^{3-2} +3$ , which claims that 5 is equal to 5, which is correct.
