The domain of the function f(x) is where the area under the square root (aka the radicand) is positive or zero. We have to write that the radicand is greater than or equal to zero, so

$\dfrac{1}{2}x-10 \geq 0$ .

Identify the equation of the line perpendicular to 9x - 3y = 18.

sweet [91]

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The exemplar equation has slope

9x - 3y = 18

- 3y = -9x + 18

y = 3x - 6

m = 3

so perpendicular slope will be -1/3

D has such a slope

3y = -x + 1

y = (-1/3)x + 1/3

Answer: arc ef is 68

Step-by-step explanation:

Since EF and FG are the same length (given)

and DE and DG are the same length (both are radius of the circle)

and DF is a shared side, the 2 inscribed triangles are congruent, making angle EDF also 68

The measure of an arc is the same as the measure of the angle across from it

Whats the sum of the interior angles of a 37 gon

Zinaida [17]

Since we have a 37-gon here, the sum of the interior angles will be:
(37 - 2) * 180 
= 6300 degrees
