The value of a house decreases at a steady rate of 20% each year. What is the total percentage loss (to the nearest integer) in
Westkost [7]

Answer: The total percentage loss would be 67%.

Step-by-step explanation:

Since we have given that

Rate of decline each year = 20%

Number of years = 5

We need to find the total percentage loss in value of the house at the end of 5 years.

So, Total percentage loss would be

1-(1-\dfrac{r}{100})^5\\\\=1-(1-\dfrac{20}{100})^5\\\\=1-(\dfrac{4}{5})^5\\\\=1-(0.8)^5\\\\=0.67\\\\\approx 67%

Hence, the total percentage loss would be 67%.

What is the slope of the line that passes through (8,4) and (6,7)?
bija089 [108]
slope=\frac{y_2-y_1}{x_2-x_1}\\\\ 
(x_1,y_1)=(8,4)\\ 
(x_2,y_2)=(6,7)\\\\
 slope=\frac{7-4}{6-8}=\frac{3}{-2}=-\frac{3}{2}\\\\
Slope\ is\ equal\ to\ -\frac{3}{2}.
