48.984 meters

Step-by-step explanation:

The distance around a circle is called the circumference, the formula for the circumference is...

$C=\pi d$

$C=2\pi r$

Since we have the diameter we will be using the first one.

$C=3.14*15.6$

$C =$

48.984 meters.

Trylon Eager took out an $85,000, 20-year term policy at age 40. The premium per $1,000 was $5.00. He will be 60 years old this

Bingel [31]

So based on the given values above, it was given that the premium per $1,000 was $5.00 and now that he is 60 years old, the premium per $1,000 became $5.90. Therefore, the percent increase from $5.00 to $5.90 would be 18%. Hope this is the answer that you are looking for.

Simple interest. 2700=2200(1+r)^5

kykrilka [37]

Solve your equation step-by-step.

2700=2200(1+r)^5

Flip the equation.

2200(r+1)^5 = 2700

Divide both sides by 2200.

2200(r+1)^5 / 2200 = 2700 / 2200

(r+1)^5=27/22

Solve Exponent.

(r+1)^5=27/22

((r+1)5) ^1/5 = (27/22)^1/5 (Raise both sides to power)

r+1=1.041809

r+1−1=1.041809−1(Subtract 1 from both sides)

r = 0.041809

Check answers. (Plug them in to make sure they work.)

r = 0.041809 (Works in original equation)

Which sequence of transformations performed on shape I confirms the congruence of shape II and shape I?

vampirchik [111]

Answer:

Option D. a 180° rotation about the origin and then a translation left 8 units.

Step-by-step explanation:

See the attached figure_1

From the graph: Point A'(-12,-6) is the image of point A(4,6)

We will check which sequence of transformations is true:

A. a reflection across the y-axis and then a translation down 16 units

A(4,6) ⇒(-4,6)⇒(-4,-10) (Wrong sequence)

B. a 90° counterclockwise rotation about the origin and then a translation down 8 units

A(4,6) ⇒(-6,4)⇒(-6,-4) (Wrong sequence)

C. a 90° clockwise rotation about the origin and then a translation left 16 units

A(4,6) ⇒(6,-4)⇒(-10,-4) (Wrong sequence)

D. a 180° rotation about the origin and then a translation left 8 units

A(4,6) ⇒(-4,-6)⇒(-12,-6)A' (True sequence)

Note: the rules is the attached figure_2
