<h2>
Hello!</h2>
The answer is:
The correct option, is the second option:
b || c ( b and c are parallel).
<h2>
Why?</h2>
To solve the problem, let's remember the following relationship:
If:
and
Then:
So, from the statement we know that a and b are parallel (a || b), so, if a and c are parallel ( a || c) it means that b and c are parallel ( b || c).
Hence, the correct option is:
The second option, b || c ( b and c are parallel)
Have a nice day!
Answer: 126cm, 136.5cm, 147cm, 144cm, 100cm
Step-by-step explanation: 5% increase is the same as multiplying by 1.05, and to do it in reverse you divide instead.
120*1.05=126cm
130*1.05=136.5cm
140*1.05=147cm
151.2/1.05=144cm
105/1.05=100cm
Answer:
4 + (-10)
Step-by-step explanation:
for the answer you are taking adding TEN negatives from a non negative number. So we subtract 4 - 10 this equals -6 which is the same as -10 - (-4)
Answer:
3t
Step-by-step explanation:
7t-3t+4t-5t
Combine like terms
7t -3t = 4t and substitute back into the expression
4t +4t -5t
4t+4t = 8t and substitute back into the expression
8t - 5t
3t
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.
