i'll give points, and follow, if you can : ) what are real-life applications of the quadratic model? how can the axis of symmetry, the vertex, and the zeros of the parabola be used to solve real-world problems?

As we see, the quadratic formula, which is a formula that is used to solve quadratic equations, can easily come up in real-life situations. ... A quadratic equation is an equation that can be put in the form ax2 + bx + c = 0, where the highest exponent is 2.Every parabola has an axis of symmetry which is the line that divides the graph into two perfect halves. Like the ellipse the parabola and its applications can be seen extensively in the world around us. The shape of car headlights, mirrors in reflecting telescopes and television and radio antennae are examples of the applications of parabolas.arabolas have different features too. If a material that reflects light is shaped like a parabola, the light rays parallel to its axis of symmetry will be reflected to its focus, irrespective of where the reflection occurs. Conversely, if the light comes from the focus, it will get reflected as a parallel beam that is parallel to the axis of symmetry. These principles work for light, sound, and other forms. This property is very useful in all the examples seen in the real world.

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
