Step-by-step explanation:
40 days = 15 boys
1 day = 15/40 = 3/8
therefore,
30 days = 3/8 × 30
= 11.1/4 boys or 11.25boys

Answer:
f(x) = sin(0.62832(x +1))
Step-by-step explanation:
The period of the function is the difference between x=4 and x=-6, which is 10 units. Then the horizontal scaling needs to be such that when x changes by 10, the argument of the sine function changes by 2π. That scaling will make it ...
f(x) = sin(2π(x/10)) = sin(πx/5)
The upward zero-crossing is seen to be at -1, so this function has been shifted left 1 unit. This requires we replace x with x+1:
f(x) = sin(π/5(x +1))
If we use the given numerical value for pi, this becomes ...
f(x) = sin(0.62832(x +1))
If you have |a|=b, solve a=b and a=-b
so
|-4+5x|=16
so solve
-4+5x=16 and -4+5x=-16
add 4 to both sides
5x=20 and 5x=-12
divide both sides by 5
x=4 and x=-12/5
the 2 solutions are x=-12/5 and x=4
4.5 meters = in 9 seconds
1 meter = 9/4.5 = 2seconds
so, a bee flys 1 meter in 2 seconds.
