Find the equation of the parabola for these three points

y = ax² + bx + c

(1998,271.3), (2000,304.1), (2004,490.6)

.

Aquantity with an initial value of 3900 decays exponentially at a rate of 35% every hour. what is the value of the quantity after 0.5 days, to the nearest hundredth?

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

Add the fractions and simplify 1/2+ 1/3
