Answer:
- The arcs on the Golden Gate Bridge.
Explanation:
I think about the Golden Gate Bridge, which is a suspension bridge.
As in any suspension bridge, a long cable is supported by two large supports.
The cable falls from a support, in the form of a curve concave upwards, to a minimum point that is the vertex of the<em> parabola</em>, through which the axis of <em>symmetry</em> passes, and curves again upwards to ascend to the upper end of the other support.
As a <em>unique feature</em> of this parabolic arc you can tell that the the concavity is upward; the parabola open upward.
Also, you can tell that the parabola is vertical, which means that the axis of symmetry is vertical.
The <em>symmetry</em> is clear because to the curve to the left of the vertex is a mirror image of the curve to the right of the vertex.
Answer:
86.7 ft²
Step-by-step explanation:
arc area = area of the circle x ( arc angle measure / 360°)
area of the circle = 65 / (270/360) = 86.67 ft²
First combine like terms on each side so
8x = -7x
then move -7x
so x=0
Answer:
no, you actually don't.
Step-by-step explanation:
remember: x is how many to the left, and y is how many to the top.
reposition the dots and I will see if it is right the 2nd time.
hope this helped!
