Answer:
[tex]D = 63.717[/tex]
Step-by-step explanation:
The details that complete the question are:
[tex](x_1,y_1) = (0,42.78)[/tex]
and
[tex](x_2,y_1)=(90,42.78)[/tex]
Required
Determine how far the ball travelled
Distance is calculated using:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute values for x's and y's
[tex]D = \sqrt{(42.78 - 0)^2+(42.78-90)^2}[/tex]
[tex]D = \sqrt{42.78^2+(-47.22)^2[/tex]
[tex]D = \sqrt{1830.1284+2229.7284[/tex]
[tex]D = \sqrt{4059.8568[/tex]
[tex]D = 63.717[/tex]
Hence, the ball travelled a distance of 63.717 units
