<h2><u>Problem</u>:-</h2>
3.) If y varies directly as x and y = 24 when x = 6, find the variation constant and the equation of variation.
<h2><u>Solution</u>:-</h2>
A. Express the statement “y varies directly as x”, as y = kx .
B. Solve for k by substituting the given values in the equation.
<h2><u>Answer</u>:-</h2>
- Therefore, the constant of variation is 4.
C. Form the equation of the variation by substituting 4 in the statement y = kx. Thus , <u>y = 4 x.</u>

Answer:
Width of the arch = 105 m
Step-by-step explanation:
Function representing the width of the arch,
f(x) = -0.016(x - 52.5)² + 45
where x = width of the base of the arch or horizontal distance from arch's left end
f(x) = vertical distance of the arch
From the given quadratic function, vertex of the parabola is (52.5, 45).
Coordinates of the vertex represents,
Height of the arch = 45 m
Half of the horizontal distance from the left end = 52.5 m
Therefore, width of the bridge = 2(Half the width of the bridge from left end) = 2×52.5
= 105 m
Therefore, given bridge is 105 m wide.
