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.

Step-by-step explanation:
Given
A = 
bh
a. substitute b = 6 and h = 5 into the formula
A = × 6 × 5 = × 30 = 15 units²
b.
Multiply both sides of the formula by 2
2A = bh, that is
bh = 2A ← divide both sides by b
h = 
= 
= 
= 8
c
Using
bh = 2A ← divide both sides by h
b = 
= 
= 
= 6
Answer: A 2.7 x 10^9

Answer:
(3/7)^7
Step-by-step explanation:
When multiplying exponents we can use the formula: a^m x a^n = a^m+n.
In this case, we can plug in 3/7 for a, and their respective exponents as m and n.
(3/7)^3 x (3/7)^4= (3/7)^3+4= (3/7)^7
Hope this helps!
