Answer: f(x) = 1.5*sin(x*2*pi/0.0038s)
Step-by-step explanation:
A sine function is:
f(x) = A*sin(c*x + f)
Where A is the amplitude, we know that it is 1.5
c is a constant that depends on the frequency.
f is a phase.
As there is no mention of a phase, we can assume f = 0.
Then our function is:
f(x) = 1.5*sin(c*x)
now let's find the value of c.
We know that the frequency is 262hz.
Then the period can be calculated with the equation:
T = 1/f.
T = 1/262 Hz = 0.0038 seconds.
Now, the period of a sin function is 2*pi.
whit pi = 3.14159265358979.....
Then we have that:
sin(0) = sin(c*0.0038s)
sin(0) = sin(2*pi)
then:
c*0.0038s = 2*pi
c = 2*pi/0.0038s
Then the function is:
f(x) = 1.5*sin(x* 2*pi/0.0038s)
Answer:
7
Step-by-step explanation:
difference between two number let say x&y is x-y
so, difference between their score is (-17)-(-24)
=(-17)+24 {minus of minus is plus}
=24-17
=7
1. yes
2.no
3.yes
4. no
5. yes
n, n + 2 - two consecutive odd integers
196 - the sum
The equation:
n + (n + 2) = 196
n + n + 2 = 196 |subtract 2 from both sides
2n = 194 |divide both sides by 2
n = 97
n + 2 = 97 + 2 = 99
Answer: 97, 99.
