Answer:
First option: 27 square units.
Step-by-step explanation:
The formula for calculate the area of a trapezoid is:
Where h is the height, B the larger base and b the smaller base.
Observe the figure of the trapezoid called ABCD. The length of the larger base (AB) is 12 units and the lenght of the smaller base (CD) is 6 units, but the height h is unknown, so you need to find it.
You can observe in the figure that two equal right triangles are formed, whose opposite side is the height "h". If you calculate the opposite side of one of those triangles, you will obtain the height of the trapezoid.
For this, you can use the identity .
Identify the opposite side, the adjacent side and the angle :
Substitute and solve for the height h:
Finally substitute into :
Answer:
2 is the only even prime number
SOLUTION
From the question, the center of the hyperbola is
a is the distance between the center to vertex, which is -1 or 1, and
c is the distance between the center to foci, which is -2 or 2.
b is given as
But equation of a hyperbola is given as
Substituting the values of a, b, h and k, we have
Hence the answer is
