Answer:
In the given shapes above, we can see that all shapes have four sides.
Above geometrical shapes could be named as Rectangles, parallelogram or quadrilateral.
First two shapes are Rectangles.
Third is a parallelogram.
Fourth and fifth shapes are Rectangles again.
Also we can say all those shapes with four side as quadrilaterals. (Note: A quadrilateral has four sides.)
Below shown shape has only three sides in it.
It is called a triangle when a shape has three sided close figure.
So, we could drag : Not similar - Different Type of shape.
Answer:
1.7(12) + 3(-6) = 84 - 18 = 66
Sure. The function is a parabola. Because the coefficient of the x^2 term is positive, it opens upward. that means that it vertex is a minimum point.
You can verify that the vertex is (0,24). That means that at the point x=0, the height of the bridge is 24m. So if the level water rises below 24 m, the bridge is safe to use.
To make this as easy as possible, we will find the vertex from the equation above. The vertex is sitting at (h, k) of (2, -3). The directrix is the same number of units from the vertex that the focus is. The formula for the focus for an upwards-opening parabola is

. The "a" in that formula is the 1/4 sitting in front of (y+3). Filling in accordingly, we have

. Simplifying we get

. The focus is on the axis of symmetry along with the vertex, and is 1 unit above the vertex. That means that the directrix is 1 unit BELOW the vertex and is a horizontal line. Therefore, the directrix has an equation of y = -4
