We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope

An arch for a bridge over a highway is in the form of a semiellipse. The top of the arch is 35 feet above ground (the major axis
jeka94

For given problem:

Put midpoint of ellipse, (0,0) at epicenter of bridge at ground level.

Specified length of vertical major axis = 70=2a

a=35

a^2=1225

 

Equation of ellipse:

 

x^2/b^2+y^2=1

 

plug in coordinates of given point on ellipse(25, 10)

 

25^2/b^2 + 10^2/a^2 = 1

 

625/b^2 + 100/1225=1

 

625/b^2 = 1 - 100/ 1225 = .918

 

b^2 = 625/.918 ≈ 681

 

b ≈ 26.09

 

length of minor axis = 2b = 2(26.09) ≈ 52.16 ft

 

Span of bridge ≈ 52.16 ft
