Answer:
Segment DE is half the length of segment AC. -- Substitution property of equality
Step-by-step explanation:
Here is given a proof for proving line joining mid segment is parallel and half the length of third side.
Stepwise proof is given in two columns
We find that for every line there is a justification as
STatement Justification
D and E coordinates found out MId point formula
DE and BC are measured Distance formula
DE=1/2 BC Substitution property of equality
This justification was missing in the given proof and with this included proof would be complete
The formula for point slope is:
y-y1=m(x-x1)
m is your slope: 3; plug in 4 for y1 and 2 for x1
y - 4=3(x-2)
Answer:
If Q=2.1(R)+5, then it would be 2.1(5)+5=15.5 ?
Step-by-step explanation:
First we want to know the surface of the circle, which is
with r representing the radius. In this case
To find the volume of the cylinder we have to multiply this outcome with the height.
Hence, the volume of the cylinder is about 5024 cubic cm.
Put T in the interior of <OPQ. P is the vertex of the angle. Join PT
