I believe the correct answer from the choices listed above is option A. If DF+FE=DE, then point F is <span>A. a midpoint of DE (with line over). F is the endpoint of line segment DF and is the starting point of line DE thus it is in between line DE. Hope this answers the question.</span>
The answer to the question would be 2 3/8
Hope this helps.
I would be happy to help with this question!
you would need to use the pythagorean theorem inputting 3.5 for a and 15 for c. after this you will need to solve for b and you should get the answer of 14.6feet
11 hours. The temp. decreases with time at a 2:1 ratio receptively <span />
Complete the square:
<em>x</em> ^2 - 2<em>x</em> + <em>y</em> ^2 + 4<em>y</em> + 1 = 0
(<em>x</em> - 1)^2 + (<em>y</em> + 2)^2 + 1 = 1 + 4
(<em>x</em> - 1)^2 + (<em>y</em> + 2)^2 = 4 = 2^2
Hence the center is (1, -2) and the radius is 2. (D)
