The radius of a circle is always half its diameter.
Therefore the radius of a circle with a diameter of 121 inches is 1/2(121).
Hence, the correct answer is r = 1/2 (121)
Answer with explanation:
The given function in x and y is,
y= 5 +cot x-2 Cosec x
To find the equation of tangent, we will differentiate the function with respect to x

Slope of tangent at (π/2,3)

Equation of tangent passing through (π/2,3) can be obtained by

⇒There will be no Horizontal tangent from the point (π/2,3).
The answer is 200:9 because the signs are not equal, you have convert one of them into one sign.
40cm=400cm
400mm:18mm
200mm:9mm
answer-200mm:9mm
Answer:
Much like when you divide by a negative number, the sign of the inequality must flip! ... When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!
Step-by-step explanation:
5x+20=445
The 5x represents you and your four friends because there’s a total of 5 of you the 20 represents what you paid for parking and the 445 is the total if you solve it you’ll get what you paid for each person
