The annual net sales (revenue) earned by Nintendo in the fiscal years 2000–2014, can be approximated by R(t) = −3.75t3 + 65.8t2 − 206t + 578 billion yen per year (0 ≤ t ≤ 14), where t is time in years. (t = 0 represents the start of fiscal year 2000.)† Estimate, to the nearest ¥100 billion, Nintendo's total revenue from the start of fiscal year 2004 to the start of fiscal year 2013. ¥ billion
Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
The annual net sales (revenue) earned by Nintendo in the fiscal years 2000–2014, can be approximated by
R(t) = −3.75t3 + 65.8t2 − 206t + 578 billion yen per year (0 ≤ t ≤ 14),
where t is time in years. (t = 0 represents the start of fiscal year 2000.)† Estimate, to the nearest ¥100 billion, Nintendo's total revenue from the start of fiscal year 2004 to the start of fiscal year 2013.
