slope = - 2, midpoint = (2, - 2 )
the slope m is calculated using the ' gradient formula '
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (4, - 6 ) and (x₂, y₂ ) = (0, 2 )
m = =
= - 2
calculate midpoint using midpoint formula
{ (4 + 0 ),
(- 6 + 2 )] = (2, - 2 )
gradient of perpendicular bisector = - =
equation in slope-intercept form is
y = mx + c ( m is slope and c the y-intercept )
partial equation is y = x + c
to find c substitute ( 2, - 2) into the partial equation
- 2 = 1 + c ⇒ c = - 3
y = x - 3 in slope-intercept form
Answer:
a)
b)
c) where
= number ties finished per unit time
d) t≅8.24min
e) K=109tie
J=91tie
f) K≅16.6min
J≅9.09min
Step-by-step explanation:
Data
Kara begins ten minutes before julie, so when julie joins kara she has 60 ties
t=10
a)
b)
c) where
= number ties finished per unit time
d) if kara already has 60 ties and makes 6 per minute and Julie makes 11 per minute then per minute they makes 17 ties, so one minute per 17 ties for 200 ties ¿how long?. ≅8.24min
e) K=60tie+6tie/min*8.24min=109tie
J=11tie/min*8.24min=91tie
f) K=100tie*min/6tie≅16.6min
J=100tie*min/11tie≅9.09min
Note: the amount of ties were rounded to the nearest decimal
