A car advertisement claims that a certain car can accelerate from rest to 70 km/ hr in 7 seconds. Find the car's acceleration. HINT Velocity is listed as Km/ Hr. Time is listed in seconds. First convert seconds to hours: 7 seconds = hours (round to 4 decimal places) The acceleration of the car is:

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

yes yes yes yes yes yes yes yes yes
