Where Do We See Parabolas in Everyday Life

Please explain in 2 to 3 paragraphs. :)

The trajectory of a projectile and radar and satellite dishes are a coupla things we see that resemble a parabola. The St. Louis arch and a hanging rope form a catenary, or hyperbolic parabola, similar to a parabola, but not the same.

However, there are many parabolic, or quadratic, mathematical instances that follow the rules of quadratics such as calculating maximum profits and minimum costs in business finance, determining dimensions yielding maximum area and volume, velocity and acceleration...the list goes on.

one place you can actually see one (or at least close enough) is rope that is connected between a dock and a boat. the rope sags in a roughly parabolic shape.
parabolas can also be used to find the most effective production for companies, so that they make the most money per unit sold.

Arches, such as the Gateway Arch in St. Louis, are a perfect example of parabolas. They reach a fixed point in the sky and continue down to the ground at equal distances from that fixed point.

There's a starter. I'll let you write the rest. :)

head lamps of vehicles and electric torches and parabolic reflectors used for conecentrating sun rays into an intense beam at the focal point. This in turn could be used to heat water or any other liquid.

we never do. its just a thing to confuse us about math
