Answer:
T ' = √2 T
Step-by-step explanation:
Given that
Time period = P
Frequency = T
We know that time period for pendulum given as
When the length become half then time period will become p'
L'=L/2
It means that time period will become 0.707 P.
We know that frequency T
T= 1 /P
T' = 1/P'
T'=√2/P
T ' = √2 T
Answer:
47.3
Step-by-step explanation:
as shown above ,this question can be solved using trigonometry and hence we get the perimeter to be 47.3
Answer:
– 15q6 + 18q5 - 13q4 - 15q3 + q2 + 9
Step-by-step explanation:
(18q5 – 17q3 + 9 – 15q6) – (–2q3 – q2 + 13q4)
(18q5 – 17q3 + 9 – 15q6) +2q3 + q2 - 13q4
18q5 – 17q3 + 9 – 15q6 +2q3 + q2 - 13q4
18q5 - 15q3 – 15q6 + q2 - 13q4 + 9
– 15q6 + 18q5 - 13q4 - 15q3 + q2 + 9
Answer:
(x+6) feet, 110sq ft
Step-by-step explanation:
Area = width * length = something * (x + 7)
Width = (x+6) as 6 and 7 add to 13 and times to 42.
To confirm expand (x+6)(x+7)=x^2+6x+7x+42=x^2+13x+42
(x+6) feet
4^2+13(4)+42=16+52+42=110 sqft
