Answer:

Step-by-step explanation:
If the length of the square side is a units, then the area of the square is

In your case, the side length is

then the area is

We have that
y = 2(0.45)^x
in this problem
2-----------> is the Coefficient
0.45-------> is the Base
<span>x-----------> is the Exponent
we know that
</span><span>If
the base is less than 1 (but always greater than 0), the function will be
exponential decay
</span>It is decay because as x values
increase, y values decrease.
<span>0.45 < 1 and 0.45 > 0
therefore
the equation
</span>y = 2(0.45)^x
represents <span>exponential
decay
</span>
the answer is
exponential decay<span>

Answer:
81
Step-by-step explanation:
Answer:
After 15 years the use of said machine is no longer profitable
Step-by-step explanation:
it should be used, as long as the money generated is not smaller as the costs generated. By setting both formulas equal (calculating the x value for when they are equal) you get x = 15 and x = -2.5(which doesnt make sense in this context).
The answer is c 8 in each row
