Answer:
x = log(5) / log(3)
x=1.46497
Step-by-step explanation:
3^x - 5 =0
Add 5 to each side
3^x = 5
Take the log of each side
log 3^x = log 5
We know log a^b = b log (a)
x log (3) = log (5)
Divide side by log (3)
f(t)=-16t^2+8t+2
Take the initial velocity(8)put in for vt. Then take height(2) and put in for s. giving you the equation. f(t)= -16t^2+8t+2
Hence the number of boys in the course are: 224
