Answer:
Area of house is 60.889 m²
Step-by-step explanation:
Formula for right angle triangle is pyhtgoras
a²= b² + c²
a² =(3√2)² + (3√2)²
a² = 17.99 + 17.99
a² = 35.989
a =√35.99 ⇒ a = 5.999
Now secind triangle
a² = b² + c²
a² = ( 5.999)² + ( 5)² = 35.988 + 25 =
a = 7.908
So one side of the square is a
Area of square is = a²
A = a² = (7.908)² = 60.998
Answer:
300
Step-by-step explanation:
<em>The function uses W as the variable but the options show only x's as the variable, so I'm asumming W in the answer</em>
Answer:
0 < W < 50
Correct option: A
Step-by-step explanation:
<u>Domain of functions</u>
Some functions have restricted values of the independent variable x. It can be due to mathematical restrictions, like dividing by 0 or taking the square root of a negative number, of it can be due to practical conditions of the situation being modeled.
In this case, the area of a rectangle is given by the quadratic function.
Since the area of a rectangle cannot be negative (and should be positive, though it could be zero), the practical domain of A is determined when
Taking common factor W
Since W must be positive W>0
Or equivalently
The total interval is
Correct option: A
Please note: The real restriction should be
if we allowed the area to be positive, but I'm providing the most possible correct available option
