The inverse functions of sine, cos and tan functions are csc, sec and cot respectively.
<u>Step-by-step explanation:</u>
The reciprocals of sine, cos and tan functions are csc, sec and cot functions. The reciprocal of cosine function is secant, (sec) sec θ = 
The inverse or reciprocal function is cosecant (csc), 
The inverse tangent function is cotangent (cot) , expressed in two ways: 
or 
So 
then its reciprocal or inverse is termed as cot θ.
Since you didn't give the options, I can only give you some advice and help on the problem.
Since 22 is his limit, we want statements that mean 22 or less.
It could be "at most 22".
It could be "no more than 22".
It could be "less than or equal to 22"
It could be "up to and including 22."
Answer:
50
Step-by-step explanation:
50 because of the 100 of 79 to 7
Answer:
see explanation
Step-by-step explanation:
To determine which ordered pairs are solutions to the equation
Substitute the x and y values into the left side of the equation and if equal to the right side then they are a solution.
(- 1, - 6)
3(- 1) - 4(- 6) = - 3 + 24 = 21 = right side ← thus a solution
(- 3, 3)
3(- 3) - 4(3) = - 9 - 12 = - 21 ≠ 21 ← not a solution
(11, 3)
3(11) - 4(3) = 33 - 12 = 21 = right side ← thus a solution
(7, 0)
3(7) - 4(0) = 21 - 0 = 21 = right side ← thus a solution
The ordered pairs (- 1, - 6), (11, 3), (7, 0) are solutions to the equation
Ok, so I think
X=(90-6y-7z)/5
Y=(90-5x-7z)/6
Z=(90-5x-6y)/7
I think they are related because all of the answers (a)-(c) have 90 subtracted by the following variables. Also all of the results include fractions... I don’t know for sure if this answer is right though, sorry!! I hope this helps a little though, good luck!!
