Rewrite the function f(x)=3(x-1)^2+9 in the form f(x)=ax^2+bx+c
Otrada [13]

Answer:

f(x) = 3x² - 6x + 12

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Expand by FOIL (First Outside Inside Last)
  • Standard Form: f(x) = ax² + bx + c
  • Vertex Form: f(x) = a(bx + c)² + d

Step-by-step explanation:

<u>Step 1: Define function</u>

Vertex Form: f(x) = 3(x - 1)² + 9

<u>Step 2: Find Standard Form</u>

  1. Expand by FOILing:                         f(x) = 3(x² - 2x + 1) + 9
  2. Distribute 3:                                      f(x) = 3x² - 6x + 3 + 9
  3. Combine like terms (constants):     f(x) = 3x² - 6x + 12

A standard deck of cards has 52 cards, 4 of each type (Ace, King, Queen, Jack, 10,...,2). From a well-shuffled deck, you are dea
Wewaii [24]

Answer:

a)%85,5

b)%92,2

Step-by-step explanation:

a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.

(36/52)*(35/51)*(34/50)*(33/49)*(32/48)=0,145

Then, we need to deduct this value from the probability 1

1-0,145=0,855

The probability of the hand with at least one face is %85,5.

b)To determine the probability of a hand with at least one ace and face we will track the same road again.

(32/52)*(31/51)*(30/50)*(29/49)*(28/48)=0,0775

Then, we need to deduct this value from the probability 1

1-0,0775=0,922

The probability of the hand with at least one ace and one face is %92,2.
