A^2 + B^2 = C ^2
(500)^2 + (1200)^2 = C^2
1690000 = C^2
C = 1300 ft
A support wire runs from the top of a tower to the ground. If the tower is 1200 feet tall and the wire is attached to the ground 500 feet away from the tower, how long is the support wire?

Thank you!
This a job for the Pythagorean Theorem since the wire forms the hypotenuse of a right-angle triangle.
1200^2 + 500^2 = c^2
1,440,440 + 250,000 = c^2
1,690,440 = c^2
1,300.17 = c
1200^2 + 500^2 = c^2
1,440,440 + 250,000 = c^2
1,690,440 = c^2
1,300.17 = c
where did that .17 come from?
This is just a scaled-up 5-12-13 triangle
Just to note: 1200^2 is not 1440440, it is 1440000, since 12^2 = 144

Determine whether the function is linear. If so, give the slope and y-intercept of the function's graph.
f(x)=6x−3x+1
