Answer:

X1=-7, X2=9

Step-by-step explanation:

(x-1)²-20=44

x²-2x+1-20=44

x²-2x-19=44

x²-2x-19-44=0

x²+7x-9x-19-44=0

x²+7x-9x-63=0

x(x=7)-9x-63=0

x(x+7)-9(x+7)=0

(x+7)(x-9)=0

x+7=0/x-9=0

X1=-7/X2=9

Hope this Helps!

A football is kicked into the air. The height of the football can be modeled by the equation

Alinara [238K]

Answer:

x = 0 and x = 1

Step-by-step explanation:

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

$h = -16x^2 + 16x$

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

$-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1$

So, it will touch the ground at x = 0 and x = 1 seconds.
