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

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
