Answer: 49
Step-by-step explanation: 7 • 7 = 49 so 49 can be a perfect square! Hope this helps! The others can’t be rational squares because they are all irrational!
DENSITY = MASS/VOLUME:
OR VOLUME = MASS/DENSITY:
Volume = 315/10.5 = 30 cm³
The domain of the function is the set of all real numbers and the range of the function is the set of all values greater than -2
<h3>How to determine the domain and the range?</h3>
The function is given as:
f(x) = 2(x -4)^2 - 2
A quadratic function can take any real number as its input.
So, the domain of the function is the set of all real numbers
The vertex of the above function is:
Vertex = (4, -2)
And the leading coefficient is:
a = 2
The y value of the vertex is;
y = -2
Because the value of a is positive, then the vertex is a minimum.
This means that the range of the function is the set of all values greater than -2

Step-by-step explanation:
Since the triangle is isosceles , then the 2 legs are congruent , that is
5n - 17 = 2n + 1 ( subtract 2n from both sides )
3n - 17 = 1 ( add 17 to both sides )
3n = 18 ( divide both sides by 3 )
n = 6
Then
2n + 1 = 2(6) + 1 = 12 + 1 = 13
each of the congruent sides = 13 cm
the third side has length n = 6 cm
Perimeter = 13 + 13 + 6 = 32 cm
