Ahouse was valued at $120,000 in the year 1992. the value appreciated to $160,000 by the year 2007.
use the compund interest formula s=p(1+r)t to answer the following questions.
a) what was the annual growth rate between 1992 and 2007?
r = round the growth rate to 4 decimal places.
b) what is the correct answer to part a written in percentage form?
r = %.
c) assume that the house value continues to grow by the same percentage. what will the value equal in the year 2010 ?
value = $ round to the nearest thousand dollars

A) 0.0194

B) 1.94%

C) $ 170,000

Step-by-step explanation:

Value of house in 1992 = P = $ 120,000

Value of house in 2007 = S = $ 160,000

Time difference from 1992 to 2007 = 15 years

Part A)

The formula of compound interest is:

P is the original amount i.e. $ 120,000

t is the time in years which is 15 years

S is the amount after t years which is $ 160,000

r is the annual growth rate

Using the values, we get:

Thus, the annual growth rate is 0.0194

Part B)

In order to convert a decimal to percentage, simply multiply the decimal by 100.

So, 0.0194 in percentage would be 1.94%

Part C)

We have to find the value of house in 2010 i.e. after 18 years. So t =18

Using the values in the formula, we get:

Rounded to nearest thousand dollars, the value of the house would be $ 170,000

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
