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:
Step-by-step explanation:
You;ll run into this formula a lot. Make sure you study it carefully.
A = 25
a = 5
d = 13
Find n
25 = 5 + 13*(n- 1)
20 = 13(n - 1)
This isn't going to work out. 20/13 does not give a whole number which it should.
So here first you have to have same denominators to subtract and add.
to make same denominator you have to multiply something to them which meets up to their lowest common multiple (LCM). so here the easiest thing is multiply each denominator to the other but remember you have to multiply them to the numerator too.
3×9/5×9-2×5/9×5
so it becomes
27/45-10/45
17/45
as you cant bring to its simplest form since the answer in a prime no. leave it like that.
The median is 1.5, hope this was helpful :)

Step-by-step explanation:
1) according to the condition two angles are equal, then two sides are equal also, it means
2) √x+4=√(5x+4);
3) the 'x' can be calculated if to solve this equation:
;
4) finally, answer: 9.
