Answer:
√3
Step-by-step explanation:
cot²(θ) = csc²(θ) -1 . . . . . a relevant identity
= 1/sin²(θ) -1
= (1/(1/2))² -1 = 2² -1 = 3
Then ...
cot(θ) = √3 . . . . . . . . take the square root
Answer:
10.63
Step-by-step explanation:
Data provided in the question
Data = 30 subjects
The Variance of scores = 113.00
The calculation of standard deviation is shown below:-
As we know that
Variance = Standard deviation^2
Therefore,
Standard deviation = 
= 
= 10.63
Therefore for computing the standard deviation we simply applied the above formula.
Answer:
x^2-5x-24
Step-by-step explanation:
So you just plug in the X value of the number that d represents for example if I plug in 2 for d
7(2)^2+10=38
