Question

A solar fire starter is designed so that its cross-sections are in the shape of a parabola. Given that the diameter of the solar fire starter at its opening is 24 centimeters and the igniter is located 9 centimeters from the base along the axis of symmetry, what is the depth of the fire starter

Answer 1

Answer:

$x=0.04m$

Step-by-step explanation:

From the question we are told that:

Diameter $d=24cm$

Radius $r=24/2=>12cm$

Igniter distance $d_g=9cm$

Generally the equation for depth  is mathematically given by

 $r^2=4d_gx$

Therefore

 $x=\frac{r^2}{4d_g}$

 $x=\frac{12^2}{4*9}$

 $x=4cm$

 $x=0.04m$
