The domain of a function is the set of input or argument values for in which the function is real and defined. This is the definition of Domain. The function,y=x2+4x, has no undefined points or domain constraints. Therefore, the domain is - ∞ < x < ∞.   (∞=infinity symbol)

dmitriy555 [2]

Answer:

No, diagonal of square C is 70.71ft

Step-by-step explanation:

Given in the question that length of one square = 5 ft

Length of Square C = 10 small squares

1 square = 5 ft

10 square = 5ft * 10

                = 50 ft

As we know that in a square all side are of equal length and make an angle of 90° at each corner.

So, by using pythagorus theorem

Diagonal of square² = side² + side²

Diagonal of square² = 2side²

Diagonal of square = √(2side²)

Diagonal of square = √2 (side)

where side = 50 ft

Diagonal of square = √2 (50)

Diagonal of square = 70.71 ft
