Answer:
square root of 81
Step-by-step explanation:
so 9 is rational number.
the rest are irrational number
Answer:
Option A is correct.
Step-by-step explanation:
We are given the expression:
w(x) = (x+125)^1/3
We need to find w(50)
Putting x = 50 in the above equation
w(x) = (x+125)^1/3
w(50) = (50+125)^1/3
w(50) = (175)61/3
w(50) = 5.59
w(50) = 5.6
So, Option A is correct
-5x > 35
-x > 7
(Divide it by 5)
Answer:
(x - 4)² + (y + 6)² = 5²
Step-by-step explanation:
rearrange the general equation as follows
collect the terms in x and y together and place the constant on the right side
x² - 8x + y² + 12y = - 27
add (half the coefficient of the x/y term)² to both sides
x² + 2(- 4)x + y² + 2(6)y = - 27
(x - 4)² + 16 + (y + 6)² + 36 = - 27 + 16 + 36
(x - 4)² + (y + 6)² = 25
(x - 4)² + (y + 6)² = 5² ← in standard form
Answer:
The correct answer is x > 2.
Step-by-step explanation:
An inequality compares two quantities unlike an equality. An inequality is written with either a greater than ( > ) or lower than ( < ) or greater than equal to ( 
) or less than equal to ( 
) signs. We solve the above given inequality to find the solutions of the unknown x.
Firstly we change the right hand side quantity to fraction.
We then transfer the - 
to the right hand side and add them. The inequality sign does not change as we are simply adding or subtracting terms from both the ends.
Finally we divide both sides with 
to get the required solution. The inequality sign does not change as we are multiplying both the ends with a positive quantity.
This gives us the answer as x > 2.
