Step-by-step explanation:
-inf<= x <= inf
-inf<= y <= 4
It is a function
Number 3 / last one is -49 hoped I helped you
d = diameter of the copper wire = 8.252 mm
r = radius of the copper wire = d/2 = 8.252 mm /2 = 4.126 mm = 0.004126 m
A = area of cross-section of the copper wire = πr² = (3.14) (0.004126)² = 53.5 x 10⁻⁶
L = length of the copper wire = 2.40 km = 2400 m
ρ = resistivity of copper wire = 1.68 x 10⁻⁸
resistance of copper wire is given as
R = ρL/A
inserting the above values in the formula
R = ( 1.68 x 10⁻⁸)(2400)/(53.5 x 10⁻⁶)
R = 0.753 ohm
We conclude that the coordinates that describe the location of point P' are (4, -2).
<h3>
What ordered pair describes the location of P'?</h3>
For a random point with coordinates (x, y), a reflection over the x-axis only changes the sign of the y-component. So the coordinates after the reflection are (x, -y).
In this case, the coordinates of point P are (4, 2), so if we apply a reflection over the x-axis to get the point P', the coordinates are:
(4, -2)
Where we just changed the sign of the y-component.
We conclude that the coordinates that describe the location of point P' are (4, -2).

4/5 is greater because when you times it by 6 the numerator becomes 24 therefore it is greater
