Answer:
a) e(0,2)
b) 1
c) read below
d) read below
Step-by-step explanation:
Midpoint:
to calculate the midpoint e of a segment
e((x1+x2)/2, (y1+y2)/2)
so (-1+1)/2 and (3+1)/2
e(0,2)
Slope formula:
the slope of a straight line between two points is
so between e and B it's equal to (4-2)/(2-0) = 1
Condition for perpendicularity : slope(AC) = -1/slope(eB) = -1
so we calculate the slope of a straight line through A and C
(1-3)/1-(-1) = -2/2 = -1 so they are perpendicular
Area:
eB is the height of the triangle as it's perpendicular to the base, so applying the standard formula Area = (AC*eB)/2 we can find the area
Answer:
Cork: Less
Wood: About the same
Metal: More dense
Step-by-step explanation:
Whether or not a block floats inside water is dependent on its density. If it is floating, it means it has a lower density. If it is sinking, it means it has a higher density. If it has the same, it will be half under and half over.
Mathematically, specific gravity can be used to support this phenomenon.
*In this context, water is our reference and the blocks are our substances.
Since Boyancy force can be described 
(the weight of the fluid disperced), having a higher density p than the reference liquid inherently will cause a greater downwards force from gravity.
Answer:
25 mins
Step-by-step explanation:
Harpeet worked -- x mins
Aiysha worked -- 2x mins
If Aiysha worked 50 mins, Harpeet worked:
2x = 50
x = 25 mins
Thenks and mark me brainliest :))
15+15+15=45 Hope this helps.
