Answer:
[M⁰L¹T⁰]
Step-by-step explanation:
given expression,
from the expression x = A sin (2 π f t),
A and f are constants
dimension of A =?
As the sine factor is dimensionless means that sine function will not have any dimension it is dimensionless.
so, remaining
x = A sin ()
so, the dimension of x is L
hence, the dimension of A also will be equal to L i.e [M⁰L¹T⁰]
Answer: 89 students remained at school that day.
Step-by-step explanation: If there are 104 students, and 15 are absent, you subtract, therefore, the answer is 89.
The answer is b
it's a special triangle
I haven't done this in a while, but I'm pretty sure the answer is D, (-3, -1.)
If you were to substitute x for -3 and y for -1 in the first inequalities and simplify, it would look like this:
-1 > -3-2
-1 > - 5
And that inequality is true, because -1 is bigger than -5. Let's also substitute in the other inequality, which would be:
-1 > 2(-3) + 2
-1 > -6 + 2
-1 > -4
And -1 is bigger than -4. So, I think the answer would be D because substituting for those values of x and y would stil. make the inequalities true.
