A certain drug raises a patient%26#039;s heart rate, h(x), in beats per minute, according to the function h(x) = 70 + 0.2x, where x is the bloodstream drug level, in milligrams. The level of the drug in the patient%26#039;s bloodstream is a function of time, t, in hours, according to the formula g(t) = 300(0.8)^t. Find the value of h(g(4)), the patient%26#039;s heart rate in beats per minute, to the nearest whole number
MATH HElP!?
g(t) = 300(0.8)^t.
g(4)=300(0.8)^4
= 300 . (0.4096)
= 122.88
h(x)=70+0.2x
h(122.88)=70+0.2(122.88)
= 70 + 24.576
= 94.576
