Answer:

DF = 3

Step-by-step explanation:

If ABC is equivalent to EDF, then DF is equivalent to BC, which form the following ordered pairs:

D = (0,2)

F = (3,2)

It can be seen that both pairs have the same value of "y" or second value, that is 2.

As a rule, when the points are located on the y-axis (of the ordinates) or on a line parallel to this axis, the distance between the points corresponds to the absolute value of the difference of their ordinates.

So,

DF = D(x) + F(x) = 0 + 3 = 3

If we apply the equation of the distance between two points we get the same result,

DF=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}   }=\sqrt{(3-0)^{2}+(2-2)^{2}   }=\sqrt{(3)^{2}+(0)^{2}   }=\sqrt{9+0   }=\sqrt{9}=3

Hope this helps!

Answer:

  3

Step-by-step explanation:

Segment BC corresponds to segment DF. The length of BC is the distance between coordinates (0, 2) and (3, 2). These points are on the same horizontal line (y=2), so the distance between them is the difference of their x-coordinates: 3 - 0 = 3.

NEED HELP! Which equation represents a circle with a center at (-5,5) and a radius of 3 units?
Alja [10]

Equation of the circle is (x + 5)² + (y - 5)² = 9

Step-by-step explanation:

  • Step 1: Given center is (h, k) = (-5, 5) and radius is 3. Equation of a circle is given by (x - h)² + (y - k)² = r²

Equation is (x - -5)² + (y - 5)² = 3²

⇒ (x + 5)² + (y - 5)² = 9
