Answer:

Step-by-step explanation:
Given:
Area of the square = 49 in²
Required
Determine the perimeter of the one of the congruent triangles
First, we'll determine the length of the square;

Substitute 49 for Area


Take Square root of both sides


<em>When the square is divided into two equal triangles through the diameter;</em>
<em>2 sides of the square remains and the diagonal of the square forms the hypotenuse of the triangle;</em>
Calculating the diagonal, we have;
-- Pythagoras Theorem


Take square root of both sides



The perimeter of one of the triangles is the sum of the 2 Lengths and the Hypotenuse



Answer:
Step-by-step explanation:
(D). The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel.
The slope of the line passing through the points A(a, b), and B(c, d), is given by

thus, the slope of the line through <span>points (p, a) and (p, –a) is
</span>

When applying the slope formula results in division by zero, this means that the line is a vertical line.
This could have also been noticed directly, since the line contains 2 points with the same x-coordinate.
The equation of this line is x=p, since the x-coordinate is always p, no matter what y is.
If p=0, then the equation of the line is x=0, which is the y-axis itself. In this case, the y-intercept is the whole y-axis.
Answer: The whole y-axis.
It is Hyperbola I believe:)
