Hey,
You need to first find the vertex
It opens upwards, because a>0 and now you just put in the coordinates in the table like if x=1->y=2*1^2-12*1+14 and you continue to find out the points.
If two chords intersect each other inside a circle, the products of their segments are equal.
If M is midpoint of AB, then AM = MB = 24/2 = 12.
<span>Product of the lengths of the segments AM and MB:
</span>AM * MB = 12 * 12 = 144
<span>So, any chord of circle O that intersects AB at its midpoint, M, wll be separated by M into two segments such that the product of the lengths of the segments is 144.

Answer:
Total weight = 70.5 kg
Step-by-step explanation:
Rectangular frame is made from 5 straight pieces of metal. One of them goes through the diagonal of the rectangle.
2 pieces form the length of the rectangular frame, hence, they have a length of 12 m each
2 pieces from the width of the rectangular frame, hence, they a length of 5 m each
To find the length of the diagonal, we can use Pythagoras Theorem:
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 5² + 12²
Hypotenuse² = 169²
Hypotenuse = 13
Hence, the length of the piece of metal placed at the diagonal is 13cm
Find the sum of all lengths of the metal pieces.
Total length = 12 + 12 + 5 + 5 + 13
Total length = 47 m
Total weight = 1.5 × Total length
Total weight = 1.5 kg/m × 47m
Total weight = 70.5 kg
