Is that all the information provided or is there more information so that i can help you answer the question
Answer:
y+5=2⋅(x+2)
Step-by-step explanation:
Answer:
-50
Step-by-step explanation:
First, we must know that ab is the same as:
ab is the same as a multiply b
Now, since a is given as -5, we can substitute a with -5. This is shown below:
substitute ab with -5
Similarly, b is given as 10. So, we can substitute b with 10:
substitute b with 10
With this, we can now evaluate ab as shown below:
ab is equal to -50
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)
6 because 3x16= 48 and 54-48=6
Hope this helps.
