For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y-intercept. Decide which table best illustrates these values for the equation: f(x)=9x^2+5x+3

A = 9, B = 5, C = 3

the parabola opens upwards

y-intercept = 3

Step-by-step explanation:

Since the equation is f(x)=9x^2+5x+3, you can determine what a, b, and c are by associating it with a quadratics standard form, ax^2+bx+c. The numbers correspond with each letter in the skeletal equation.

To determine whether the parabola opens up or down, you can simply look at the a value. If x > 0, the the parabola will open upwards, whereas if x < 0, the parabola will open downwards.

To determine y-intercept, just plug in the value of 0 into x and solve for y.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

answer: 12/52

step-by-step explanation: my reasoning is that there are 12 face cards in a deck and a total of 52 cards in all.
