Answer:
C
Step-by-step explanation:
If the parent function is function and
then
- the graph of the function
is translated a units to the right graph of the parent function;
- the graph of the function
is translated a units to the left graph of the parent function;
- the graph of the function
is translated a units up graph of the parent function;
- the graph of the function
is translated a units down graph of the parent function.
In your case, the grapgh of the function is translated 2 units up the graph of the function
In this attached picture according to the conditions of the problem we have an isosceles trapezoid and since we know that legs are equal (AD=BC=5 cm), we have to calculate bases and height in order to find the area. Working with the triangle BCD, we apply Pythagoras theorem and find that CD = = 10 cm. Since BDC is a right triangle, applying theorem for the area of triangles, we find that
and BF=
. Since ABCD is an isosceles trapezoid, triangles ADE and BFC are congruent with Angle Side Angle theorem. Then, DE=FC and with the help of Pythagoras theorem, DE=FC=2.5 cm. Then, AB=EF=5 cm and the area of the trapezoid is
