We have that
F(x)=x²<span>-10x+44
</span><span>Group
terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete
the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
see the attached figure
Y= 16(0.25)^x
The exponential equation represents an exponential decay because the rate of decay is 0.25 which is less than 1.
The general form equation is:
y(x)= a(1-r)^x such that r is the decay percent.
1. 86/2=43/new price of one shirt
2. 43-15=28/original price of one shirt
Your answer would be $28.
