Answer: g(1-t)=3t^2-t-1
Step-by-step explanation:
g(x)=3(x)^2-5(x)+1
g(1-t)=3(1-t)^2-5(1-t)+1
g(1-t)=3(1-t)(1-t)-5-(-5t)+1
g(1-t)=3(1-t-t+t^2)-5+5t+1
g(1-t)=3(1-2t+t^2)-5+5t+1
g(1-t)=3-6t+3t^2-5+5t+1
g(1-t)=3-5+1-6t+5t+3t^2
g(1-t)=-1-t+3t^2
g(1-t)=3t^2-t-1
If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price
If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way

Answer:
Step-by-step explanation:
V = 1/3 * pi * r^2 * h
r = ?
pi = 3.14
h = 17 cm
3*V = pi * r^2 h = r^2 Divide by pi
3*V/pi = r^2 h = r^2 Divide by h
3*V/(pi*h) =r^2 Take the square root of the left to get just r
sqrt(3*V/(pi*h)) = r Now solve the equation.
sqrt(3*538.25 /(3.14*17)) = r
sqrt(1614 / 53.38) =
r = sqrt(30.24)
r = 5.493
