The correct answer is: 1760.00 Hz
Explanation:
The formula to find the unknown frequency is:
(2^n)*f
Where n = Number of octaves above to the known frequency (A4) = 2
f = Known frequency (of A4) = 440 Hz
Hence
(2^2)*(440)
1760 Hz (of A6)<span />
Answer:
value of a = 6.93 m
hence , (b.)
Step-by-step explanation:
the given triangle is a right angled triangle, so
by using trigonometry.
=》

and we know,
=》

so, by above values of tan ( a ) we get,
=》

=》

=》

=》

=
=》

hence, a = 6.93 m
Answer:
27
Step-by-step explanation:
Given that the total number of people protesting is 81. These people are either male - Student or non student or Females (student or non students)
