Answer: our function is:
f(x) = A*sin(2*pi*270s*x)
Step-by-step explanation:
We have that the frequency of a given engine is 270 hz, it starts at 0, so we may represent this with a sin function (because sin(0) = 0)
Then we could use the function
f(x) = A*sin(c*x)
A is the maximum intensity of the hum, and c depends on te frequency, we know that the period of a sin function is 2pi, then:
f = 270/s
T = 1/270s
c*1/270s = 2pi
c = 2*pi*270s
Then our function is:
f(x) = A*sin(2*pi*270s*x)
(x/2) + 1 = -5.......add -1 to both sides
x/2 = -5 - 1
x/2 = -6 .....multiply both sides by 2
x = -6 * 2
x = -12
Answer:
12x-15=p
Step-by-step explanation:
This would be the equation but i have no idea what ur asking.
so 12 is the money and x is the number of the hours which represents any number of hours. i subtracted 15 for charge and the total pay for week or month or whatever is also unknown.
hope this helps you!!:)))
Answer:
164 is not a perfect square
Step-by-step explanation:
Because if you calculate its square root, 164 doesn't have a whole number as its square root and a perfect square needs the square root to be a whole number.
