Therefore, the total number of heartbeats in 6 hours is \(\boxed{22500}\).
A climatologist models the average global temperature rise as a function of CO₂ levels using the formula:
T(x) = 0.02x + 0.5\sqrt{x} + 14
where \(T(x)\) is the temperature in °C and \(x\) is the atmospheric CO₂ concentration in ppm above pre-industrial levels. If \(x = 150\) ppm corresponds to 2020, what is the predicted temperature in 2100 if \(x\) increases to 250 ppm?
\[ T(x) = 0.02x + 0.5\sqrt{x} + 14 \]
We compute \(T(150)\) and \(T(250)\), then find the difference to estimate the temperature increase, though the function already gives the full value at each \(x\).
First, compute \(T(150)\):
\[ \sqrt{150} \approx 12.247 \]
