Answer:
y = 16sin(2π/ 3)t.
Step-by-step explanation:
When displacement = 0 at time = 0 we use the sine function.
The formula is y = A sin(2πft) where A = the amplitude, f = frequency which is 1/period and t = the time.
So for this SHM the function is
y = 16sin(2π/ 3) t.
You are correct.
Answer:
23x^2
Step-by-step explanation:
When adding variables, if they have the same exponent then all that needs to be done is add the constants. In this case both have x^2 so the answer is 23x^2. Hope this helps! :)
X=4
-4x4=-16
-16-2=-18
-18/3=-6
We start to solve this by looking for the formula that let us calculate an average value, this formula would be:
where Save is the average score and s is the score of each exam, Since we know the value of the score Save and 4 of the exams we can replace them in the formula, like this:
And we can solve for s5, which is the score that we need to find, like this:
Then, Pedro must have a 55 score on the fifth test
I'm pretty sure that the answer is A
