When you simplify the expression 1/1+cot^2x the final product is C. sin^2 (x).
Hope this helps!
Joe is 15, 45-15=30 30/2=15
Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get

Now when k =1.6 , y = 40 then x will be

Therefore the value of x is 25 when y =40.
Answer/Step-by-step explanation:
-33 is not a whole number. A whole number is a number(positive) that contains no decimals nor fractions.
D must be perpendicular to a because d is parallel to c. c is perpendicular to b. b is parallel to a.
