Answer:
x^8 * y^3
Step-by-step explanation:
Square both sides to get (x^10 * y^4)/(x^2 * y). Divide both sides by x^2 to get (x^8 * y^4)/y. Divide both sides by y to get x^8 * y^3.
Answer: 8/35.
Step-by-step explanation: Since 1/5 and 2/7 is not equal, you would need to find a common denominator. The common denominator would be 35 = 7/35 + 10/35. After you add you will get your answer. I hope this helps. ;)
Answer:
The slope of the line is 1 , because the slope of another line parrallel to it is 1 and we know the when two lines are parralel the slope are equal
Answer:
The value of given trigonometrical expression is cos²x + sin²x = 1
Step-by-step explanation:
Given trigonometrical expression as :
( 
) - sec x = tan x
Or, ( ) = tan x + sec x
or, ( ) = ( 
) + ( 
)
or, ( ) = ( 
)
Now, cross multiplying both side
I.e (cos x) × (cos x) = ( 1 - sin x ) × ( 1 + sin x )
or, cos²x = 1 - sin² x
or, cos²x + sin²x = 1
So, Value of expression is cos²x + sin²x = 1
Hence The value of given trigonometrical expression is cos²x + sin²x = 1 answer
