Answer:
Quadrilateral ABCD is a <u>parallelogram</u>
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a <u>kite</u>
Step-by-step explanation:
without solving, im guessing that quad ABCD is a paralellogram (//gram)
lets test this theory
see if the slope of AB and CD, and BC and AD is the same
slope AB and CD
AB:
-7--4/11-9
=-3/2
CD:
-1--4/11-13
=3/-2
=-3/2
slope is the same
slope BC and AD
BC:
-4--1/9-11
=-3/-2
=3/2
AD:
-7--4/11-13
=-3/-2
=3/2
slope is same
because 2 pairs // sides ---> //gram
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite
hope this helps!
please mark brainliest thank you !
Answer:
120 degrees.
Step-by-step explanation:
If it is a regular 6 sided figure then each interior angle is 180 - (360/6)
= 120 DEGREES.
Answer:
y=2x+2
Step-by-step explanation:
<u>Answer:</u>
Height of cables = 23.75 meters
<u>Step-by-step explanation:</u>
We are given that the road is suspended from twin towers whose cables are parabolic in shape.
For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.
Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of 
or 
, and y at 95.
We know that the equation of a parabola is in the form 
and here it passes through the point 
.
So new equation for parabola would be 
.
Now we have to find the height 
of the cable when 
.
y = 23.75 meters
