In the year 1985, a house was valued at $110,000. By the year 2005, the value had appreciated to $145,000. Find the annual growth rate between 1985 and 2005 assuming that the value continued to grow by the same percentage and use it to write a function that models the exponential growth in the house’s value in dollars V over time t, where t is the number of years since 1985.

Write your answer in the form V(t)=a(b)^t . Round the b value to 4 decimal places.

5x + 2 = 12 solve the following equation. then place the correct number in the box provided.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

The price of an item has been reduced by 30%. the original price was $30. what is the price of the item now ?
