What is the chemical formula for aluminum nitride? a) al3 b) aln3 c) al3n3 d) aln

Your answer is going to be D

The answer is D.) AIN.
The A comes from Aluminum.
The I comes from Aluminum as well.
And the N comes from Nitride.

The first answer is b. then the second one is a

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
