Answer:
<em>BC, BD, BQ, CB, CD, CQ, DB, DC, DQ, QB, QC, QD </em>
Step-by-step explanation:
<em>"BC, BD, BQ, CB, CD, CQ, DB, DC, DQ, QB, QC, QD"</em> Are all the possible rays on line c.
49N
Step one
Given
When the force of 63 N acts on a certain object
the acceleration of the object is 9/ms^2
Firstly, we need to calculate the mass m
F=ma-------1
m= F/a
m= 63/9
m= 7kg
Step two:
Also, if the acceleration of the object becomes 7 m/s^2
then the force
Note: the mass remains the same= 7kg
F=ma
F=7*7
F= 49N
Answer: 36
By the triangle midsegment theorem, CE=16, CD=10, and ED=10.
So, the perimeter of triangle CDE is 10+10+16=<u>36</u>

Answer: x / 5 = 16
x = 80
Answer: (0, 2)
Do (x1+x2/2, y1+y2/2) as your formula to find the midpoints. -3+3/2=0 and 2+2/2=2 so the midpoint is (0, 2). Hope this helps, have a blessed and wonderful day as well as a safe one and stay healthy!
