Answer:
A = 20,000(1.05)^x
Step-by-step explanation:
To get the approximate value of the house after x years, we will use the compound interest formula
A = P(1+r)^n
P is the principal = $20,000 (cost of house)
r is the rate = 5% = 0.05
x is the time
Substitute into the expressio
A = 20,000(1+0.05)^x
A = 20,000(1.05)^x
Hence the required expression is A = 20,000(1.05)^x
Answer:
The average rate of change is equal to 
Step-by-step explanation:
we have
-----> this is a linear direct variation
we know that
The rate of change of a linear variation is a constant
The rate of change of a linear variation is equal to the slope of the line
In this problem the slope of the line is equal to 
therefore
The average rate of change is equal to
<u>Verify</u>
the average rate of change is equal to
In this problem we have
Substitute
Answer:
108 ft²
Step-by-step explanation:
Increasing by 50% means multiplying the original quantities by 1.5, that is
100% + 50% = 150% = 1.5 ( 100% is the original dimensions ), thus
new length = 1.5 × 8 ft = 12 ft
new width = 1.5 × 6 ft = 9 ft
Thus
Area = length × width = 12 × 9 = 108 ft²
