The answer is -40 because 1/2 of 4 is 2 and 1/2 of 5 is 2.5, 2•2.5=5. -2•-2•-2=-8. 5•-8=-40

How do you dilate a figure on a coordinate plane if you want to make the shape larger? How would your steps change if you want t
Papessa [141]
If u want to make the shape larger, u will have to multiply it by the scale factor that is greater then 1.

if u want to make the shape smaller, then u will multiply by the scale factor that is between 0 and 1

if the scale factor is 1, then the shapes are congruent

Write and solve an equation of ratios:

5 *10^9 years       100 m
------------------- = --------------
   5 * 10^3 yrs            x

Reducing the first fraction,
              
             100 m
10^6 = ----------
                 x
                                100 m
Solving for x,  x = ------------- = 10^(-4) m, or [10^(-1)] * [10^(-3))]
                                10^6
this comes out to one tenth of 1 millimeter.

PQ is tangent to the circle at C. In the circle, m (The figure is not drawn to scale.)
Yuri [45]

Answer:

65°

Step-by-step explanation:

From the figure we can see a circle.

It is given that, measure of arc AD = 80°  therefore m<ACD = 80/2 = 40°

Also m<D = 75°

<u>To find the measure of <DCQ</u>

We know that, an angle made by a tangent and chord is equal to the angle made by the angle made by the chord on other side of the circle.

Here m<DCQ = m<CAD

By using angle sum property,

m<CAD + m<ACD + m<D = 180

m<CAD + 40 + 75 = 180

m<CAD + 115 = 180

m<CAD = 180 - 115 = 65°

Therefore m<DCQ = m< CAD = 65°

The correct answer is third option.
