Answer:
The constant of proportionality is the ratio between numbers that expresses the rate at which the numbers increase or decrease. These two numbers are directly proportional when they increase and decrease at the same rate.
If ABCD is a parallelogram, we have to prove that slope of
AB = CD and slope of BC = DA. Using the formula m = (y1-y2) / (x1-x2), the
slope of line segment AB = 0/-4, CD =
0/-4, BC = 1, DA = 1. Going back to the
condition, the slope we get for each line segment proves that ABCD is a
parallelogram.
The type of reasoning that Vivian used into solving the
equation is the deductive. This type of reasoning is able to describe on how
the equation is done and this could be seen in the given scenario above as she
was able to show the steps in obtaining the correct answer.
38.4 I times 12.80 by 3 .
p.s I use a calculator☺
Answer:
4 cm cubed
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, we know the formula for volume is L*W*H
L=4
W=1/2
H=2
4*1/2*2=4 cm cubed
