Step-by-step explanation:
we know that
The standard form of a vertical parabola is equal to
where
(h,k) is the vertex
the focus is (h, k + p)
and
the directrix is y = k - p
Part 1) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 2) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 3) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 4) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 5) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 6) we have
Convert to standard form
The vertex is the point
the directrix is equal to

Answer: The correct option is
(E) 70.
Step-by-step explanation: We are given to find the number of triangles and quadrilaterals altogether that can be formed using the vertices of a 7-sided regular polygon.
To form a triangle, we need any 3 vertices of the 7-sided regular polygon. So, the number of triangles that can be formed is
Also, to form a quadrilateral, we need any 4 vertices of the 7-sided regular polygon. So, the number of quadrilateral that can be formed is
Therefore, the total number of triangles and quadrilaterals is
Thus, option (E) is CORRECT.
Answer:
1st, 3rd, 4th, 2nd
Step-by-step explanation:
Answer:
B) y = x + 2 and y = -x - 4
Step-by-step explanation:
Let the equation of a straight line with x-intercept 'a' and y-intercept 'b' be
The line with positive slope has x-intercept a=-2 and y-intercept b=2.
Its equation is:
Multiply through by 2
Solve for y,
For the line with a negative slope,
the x-intercept is a=-4 and the y-intercept is b=-4
Its equation is
Multiply through by -4
Solve for y
