Find the area of the pink sector(s). The diameter is 8.

First we would need the sector formula which is: 丌r^2× angle/360

To find the radius,we would have to divide the diameter by two,which is:
l8÷2=4 units

We would also need to find the total valuenof angles of pink sectors:
41+44+47=132°

As it's not mentioned,let's take pi as 3.14.

In this case,it would be:

(3.14)(4)^2(132°/360°)
=16(3.14)(11/36)
=18.4213..
≈18.4 sq. units

Thus the answer us D.18.4 units.

Hope it helps!

A geometric sequence has an initial value of 9 and a common ratio of 5. What function could represent this situation?
leonid [27]

Answer:

The functions that represent this situation are A and C.

Step-by-step explanation:

A geometric sequence goes from one term to the next by always multiplying or dividing by the same value.

In geometric sequences, the ratio between consecutive terms is always the same. We call that ratio the common ratio.

This is the explicit formula for the geometric sequence whose first term is k and common ratio is r

What is the measure of angle K? 102o 118o 134o 156o
stealth61 [152]

Answer:

The measure of angle K is 118°

Step-by-step explanation:

The sum of the internal angles of a quadrilateral is 360°. So, in this case, we can formulate the following equation:

K + L + M + J = 360°

Where K, L, M, and J represent the measure of the angle K, L, M and J respectively.

From the figure we know that: L is 46°, M is 118° and J is 78°. Replacing these values on the initial equation and solving for K we get:

K + 46° + 118° + 78° = 360°

K + 242° = 360°

K = 360° - 242°

K = 118°

So, the measure of angle K is 118°

Hope this helps :)
