Eometry A - Summer - Christian - Blended English
Given: D is the midpoint of AB; E is the midpoint of AC.
Prove: DE // BC
y
A[2b, 2c)
Complete the missing parts of the paragraph proof.
Proof:
To prove that DE and BC are parallel, we need to show
that they have the same slope,
slope of DE = V2
X2 - X
O + D-D
slope of BC =
Therefore, because
DE // BC
D(b, c)
Ela + bc)
B(0,0)
C(200)

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?

Both male and female gametes are created during the process of meiosis. the formation of male gametes is called spermatogenesis. after telophase il of spermatogenesis, there would be are all genetically male gametes created that

Ecology can best be described as the study of what
