D= v(x2 - 1)2 + (12 - y1)?
what is the approximate length of line segment ef?
6 units
7 units
8 units
9 units
10 units

The approximate length of segment EF is 7 unit  

Step-by-step explanation:

Given figure is the graph having E and F coordinate

The coordinate of point E = ( , ) = ( - 2 , -4 )

The coordinate of point F = ( , ) = ( 2 , 2 )

Let The distance between the points E and F = D

So, D =

or,  D =

Or,  D =

or, D =

∴  D =

I.e D = 7.21 unit

So, Approximate value of D = 7 unit

Hence The approximate length of segment EF is 7 unit  . Answer

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
