A manufacturer is designing a flashlight. for the flashlight to admit a focused beam the bulb needs to be on its Central axis of the parabolic reflector 3 cm from the vertex write an equation that models the problem formed when a cross section is taken through the reflectors Central axis assume that the vertex of this Parabola is at the origin and the XY coordinate plane in the problem can open in any direction​

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
