Answer:

$1/32$

Step-by-step explanation:

To understand this question you would first of all need to know about negative exponents and multiply fraction by integers.

Example I would like to find out $2^{-2}$ ,

You would first normally solve this question by squaring, which would result in 4 then divide it by 1. Like this: $1/2^{2}$

Which would be 0.25 or 1/4

Lets apply this knowledge to the following question:

1. $2^{-3} / 2^{2}$

2. $\frac{1}{8} / 4$

3. $1/32$

Answer:

m(arc FE) = 166°

Step-by-step explanation:

By theorem of intersecting chords and tangent of a circle,

Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.

m(∠GFE) = $\frac{1}{2}\text{m (arc} FE)$

83° = $\frac{1}{2}\text{m (arc} FE)$

m(arc FE) = 166°

Joaquin is constructing the perpendicular bisector of ab. What should be his first step?

Answer:

D. Open the compass so that the distance from the two points of the compass is wider than half the length of $\over{AB}$ .

Step-by-step explanation:

To construct a perpendicular for $\over{AB}$ , we must first take a compass & take the distance of its arms wider than half the length of $\over{AB}$ .

This is done in order to get two intersecting arcs in the top & bottom of $\over{AB}$ so that a perpendicular bisector can be drawn through it.

After two intersecting lines are drawn below & above $\over{AB}$ , draw a line joining these 2 points through their points of intersection. The point where it intersects $\over{AB}$ is the middle-most point of $\over{AB}$ & now a perpendicular bisector of $\over{AB}$ is constructed.
