Answer: The scale factor of the dilation is 1/3.

In a dilation, we are multiplying all the points by a constant to get a set of new points. The shapes will be similar.

In this case, we are moving from Point P at (-6, 6) to Point P' at (-2, 3).

So how does the point change. Let's write and solve the following equations.

-6k = -2 or 6k = 2
k = 1/3 k = 1/3

In both cases, the point was multiplied by 1/3. This is true of all the points.

Secant BE and CF intersect at point A inside D. What is the measure of BF?

svet-max [94.6K]

Answer:

$\text{BF}=80^{\circ}$

Step-by-step explanation:

We have been given a circle D. Secant BE and CF intersect at point A inside D. We are asked to find the measure of arc BF.

We know that when two secants intersect inside a circle, then the measure of angle formed is half the sum of intercepting arcs.

$m\angle EAF=\frac{\text{Measure of arc EF+Measure of arc BC}}{2}$

$70^{\circ}=\frac{\text{Measure of arc EF+Measure of arc BC}}{2}$

$2*70^{\circ}=\frac{\text{Measure of arc EF+Measure of arc BC}}{2}*2$

$140^{\circ}=\text{Measure of arc EF+Measure of arc BC}$

We know that degree measure of circumference of circle is 360 degrees, so we can set an equation as:

$\text{Arc EF+BC+EC+BF}=360^{\circ}$

$140^{\circ}+140^{\circ}+\text{BF}=360^{\circ}$

$280^{\circ}+\text{BF}=360^{\circ}$

$280^{\circ}-280^{\circ}+\text{BF}=360^{\circ}-280^{\circ}$

$\text{BF}=80^{\circ}$

Therefore, the measure of arc BF is 80 degrees.

What is the perimeter of the figure?

aleksley [76]

Answer:

B. 21.1 yd

Step-by-step explanation:

The perimeter of the figure is the sum of all its three sides.

Take note that the dotted line is not a side length of the figure.

The side lengths are 9 yd, 5 yd, and 7.1 yd.

Therefore, the perimeter of the figure = 9 + 5 + 7.1

Perimeter = 21.1 yd.

Also, take note of the unit of the perimeter. Unit of the perimeter would not be squared. Only area has a unit that is squarred.
