C = 2πr

C = 2π2

C = 4π

Since you have a quarter of the circle (indicated by the 90 degree angle) you can divide the circumference of the circle by four and your answer.

4π/4 = π

You would have to a four to that answer because of the lines connecting the circle segment.

Answer = π + 4

Hope this helps! ;)

Which value would make the statement true? 2/? is greater than 4/12 ? A.4 B.6 C.12 D.24

Liula [17]

Answer:

A.4

Step-by-step explanation:

Because 4/12 is simplified to 1/3 and 2/4 would be simplified to 1/2. 1/2 > 1/4

Find the coordinate that divides the directed line segment from A(-2,-4) to B(8,1) in the ratio of 2 to 3

zalisa [80]

We have that
A(-2,-4) B(8,1) 

let
M-------> the coordinate that divides the directed line segment from A to B in the ratio of 2 to 3

we know that

A--------------M----------------------B
2 3
distance AM is equal to (2/5) AB
distance MB is equal to (3/5) AB
so

step 1
find the x coordinate of point M
Mx=Ax+(2/5)*dABx
where
Mx is the x coordinate of point M
Ax is the x coordinate of point A
dABx is the distance AB in the x coordinate
Ax=-2
dABx=(8+2)=10
Mx=-2+(2/5)*10-----> Mx=2

step 2
find the y coordinate of point M
My=Ay+(2/5)*dABy
where
My is the y coordinate of point M
Ay is the y coordinate of point A
dABy is the distance AB in the y coordinate
Ay=-4
dABy=(1+4)=5
Mx=-4+(2/5)*5-----> My=-2

the coordinates of point M is (2,-2)

see the attached figure
