Sunny_sXe [5.5K]

9514 1404 393

Answer:

  $67,516

Step-by-step explanation:

"Depreciates" means the value is getting smaller. The function that describes the situation is a <em>decay</em> function:

  y= a(1-r)^x

Here, a=150000, r = 0.07, and x=11. The value is predicted to be ...

  y = 150000(1 -0.07)^11 = 150000(0.93^11) = 67,515.53

The house is worth about $67,516 in 2013.

Alborosie

Answer:

90 km / hour.

Step-by-step explanation:

Speed = distance / time

So Distance = speed * time.

The distance is the same  in both scenarios so

60 * 9 = s * 6   where s is the required speed.

540 = 6s

s = 540 / 6

s = 90 km / hour.
