You can find the perpendicular bisector of a line segment, but
there's no such thing as the perpendicular bisector of a triangle.
What does it mean to be perpendicular to a triangle ?

Answer:
r = 
Step-by-step explanation:
Express the equation with the term in r on the left side
P + Prt = A ( subtract P from both sides )
Prt = A - P ( isolate r by dividing both sides by Pt )
r =
Answer:
<em>x-intercept = 1/8</em>
<em>y-intercept = -1/2</em>
Step-by-step explanation:
Let y = 0, and solve for x to find the x-intercept. Then let x = 0 and solve for y to find the y-intercept.
x-intercept
16x - 4y = 2
16x - 4(0) = 2
16x - 0 = 2
16x = 2
x = 2/16
x = 1/8
x-intercept = 1/8
y-intercept
16x - 4y = 2
16(0) - 4y = 2
0 - 4y = 2
-4y = 2
y = 2/-4
y = -1/2
y-intercept = -1/2
Answer:
Tina's average speed for the whole journey = 56 kmph
Step-by-step explanation:
Time taken by Sean to travel from Town A to Town B = 4 hours.
Average speed of Sean = 70 km/h
We have equation of motion, s = ut + 0.5 at²
Time, t = 4 hours.
Initial speed, u = 70 km/hr
Acceleration, a = 0 m/s²
Substituting
s = ut + 0.5 at²
s = 70 x 4 + 0.5 x 0 x 4²
s = 280 km
Distance from Town A to Town B = 280 km
Tina took 1 hour more than Sean.
Time taken by Tina to travel from Town A to Town B = 4 +1 = 5 hours
We have equation of motion, s = ut + 0.5 at²
Time, t = 5 hours.
Displacement, s = 280 km
Acceleration, a = 0 m/s²
Substituting
s = ut + 0.5 at²
280 = u x 5 + 0.5 x 0 x 5²
u = 56 km/hr
Tina's average speed for the whole journey = 56 kmph
