The General Antiderivative is:
T(x) = 220/2 ln(0.92)(0.92^x)^2 + C
The Units of Measure f the General Antiderivative are DVDs, Since it Represents the total Number of DVD's Sold after (x) Weeks Since the End of JUNE.
Explanation:
- Make a Plan:
- Integral Symbol: (∫ )
- Find the general Antiderivative of the given function:
t(x) = 220(0.92^x) and identify the units of measure.
- 1 - Find the general Antiderivative of t(x)
T(x) = ∫ 220(0.92^x)dx
- 2 - Use Substitution Method:
Let: u = 0.92^x, then, du = 0.92^x ln(0.92)dx
- 3 - Rewrite the Integral:
T(x) ∫ 220/ln(0.92) udu
- 4 - Integrate with respect to u
T(x) = 220/ln(0.92) u^2/2 + C
- 5 - Substitute back (u) = 0.92^x:
T(x) = 220/2 ln (0.92) (0.92^x)^2 + C
The General Antiderivative is:
T(x) = 220/2 ln(0.92)(0.92^x)^2 + C
The Units of Measure f the General Antiderivative are DVDs, Since it Represents the total Number of DVD's Sold after (x) Weeks Since the End of JUNE.
