The parametric equations x = x1 + (x2 − x1)t, y = y1 + (y2 − y1)t where 0 ≤ t ≤ 1 describe the line segment that joins the points p1(x1, y1) and p2(x2, y2). draw the triangle with vertices a(1, 1), b(4, 3), c(1, 7). find the parametrization, including endpoints, and sketch to check. (enter your answers as a comma-separated list of equations. let x and y be in terms of t.)

  see below

Step-by-step explanation:

Filling the given numbers into the given formulas, you have ...

Line AB:

  x = 1 +(4-1)t, y = 1 +(3-1)t

  x = 1+3t, y = 1+2t . . . . . . simplify

Line BC:

  x = 4 +(1-4)t, y = 3 +(7-3)t

  x = 4 -3t, y = 3 +4t . . . . . simplify

Line AC:

  x = 1 +(1-1)t, y = 1 +(7-1)t

  x = 1, y = 1+6t . . . . . . . . . .simplify

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

the monthly balance will be $75,000
