Question

Anybody Can help with this? I just started learning about quadratic functions. Please also give details, I'm not just looking for the answer, but also I want to understand how.

•Write a real-world problem that can be modeled using a quadratic equation.

Answer 1

for this all u need to know is the quadratic formula basically

Answer 2

ur in alegbra i take it?

Answer 3

f(x)=a^2+b+c ?

Answer 4

listen timaasshorty

Answer 5

go to mathway.com, with that website u can like get an A in alegbra

Answer 6

it can explain how to solve problems too, if u pay, or u can create facebook accounts over and over and get 1 day free trial

Answer 7

thanks for letting me know, I use the website, too. But I like this one also.

Was I right about the formula?

Answer 8

mathway.com is like a calculator

Answer 9

smart math computer something like that and as for the formula

Answer 10

google the formula lol

Answer 11

I know but I'm not looking for a calculator.

Answer 12

ax2+bx+c=0

Answer 13

it can explain how to solve problems step by step too

Answer 14

I'm looking for help with this:

Write a real-world problem that can be modeled using a quadratic equation

Answer 15

ax^2+bx+c=0

Answer 16

real world problem? its probably a word problem it wants u to make

Answer 17

quadratic functions model parabolas

something like an arch is a parabola

you could also model the time it takes an object to hit the ground if you threw it up in the air using a quadratic function

Answer 18

Answer 19

When an object is thrown or projected, it follows a curved path called a trajectory. If we neglect air resistance, and assume that the object is fairly dense, and that the object is close to the earth's surface,

the path could be described by:

H = vt + h -.5at^2.

H = the height of the object above its initial position (usually taken as the ground) after some elapsed time

v = the initial velocity of the object

t = the elapsed time

h = the initial height of the object above ground

a = the acceleration due to gravity: approximately 32 feet per second squared or 9.8 meters per second squared.

Answer 20

Lol I know that sam, but I'm confused whether there are specific numbers I need to apply to a qaudatric formula. or I could insert any numbers ?

Answer 21

quadratic formula: y = ax^2+bx+c.

Answer 22

Very simple is the surface of the room.

What is the surface of square shaped room of height 3meters whit floor, ceiling and walls

walls are 3*m*(4*x)
floor and ceiling is 2*x^2

together is 2*x^2+12[m]*x and is square function

Answer 23

most common types as the other guy stated: One of the most common real life quadratic functions deals with projectile motion - that formula is h(t)=-16t^2+vt+c, where v represents the initial velocity and c represents the initial height.... so think of throwing a ball up in the air if it is thrown from a distance of 3 m above the ground with a velocity of say 10 the equation that would represent the height of the ball at any given time after release would be h(t)=-16t^2+10t+3....from there any t (representing the number of seconds since release of ball) it will give the height of the ball...you could also find the maximum height of the ball and how long it takes to get there (vertex) and when the ball will hit the ground (use quadratic formula and solve when h(t) is 0).... that can get you started, maybe?

Answer 24

ur welcome

Answer 25

thanks for all that information, I needed it,

y=a(x+2)^2+3 That would be a quadratic equation?

Answer 26

yes it would i believe

Answer 27

I just noticed you just gavee an example . Thanks so much (: So that's all I needed!
