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
- It is quadratic polynomial.
- A quadratic polynomial has 2 as its degree.
- It is monomial.
- A monomial consists of one term.
- It is constant or zero polynomial.
- When a term doesn't have any degree it is termed as zero or constant polynomial.
- It is also a monomial.
- Because it consists of only one term.
- It is constant or zero polynomial.
- Because it doesn't have any power.
- It is again a monomial.
- It is having only one term that is -9.
