An architect is designing a tunnel and is considering using the function y = -0.12x2 + 2.4a determine the shape of the tunnel's entrance, as shown in the figure. In this model, y is the height of the entrance in feet and x is the
distance in feet from one end of the entrance.

there is no graph so i cant sorry

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

b.   e = 7.5h

hope this , lovely!
