Solve y=-3x² + 4.5x – 20<br> Use the Quadratic formula

statuscvo [17]

Answer:

$x=0.75 \pm 2.47067i$

Step-by-step explanation:

Quadratic Formula: $x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}$

√-1 is imaginary number i

Step 1: Define

y = -3x² + 4.5x - 20

a = -3

b = 4.5

c = -20

Step 2: Substitute and Evaluate

$x=\frac{-4.5 \pm \sqrt{4.5^2-4(-3)(-20)} }{2(-3)}$

$x=\frac{-4.5 \pm \sqrt{20.25-240} }{-6}$

$x=\frac{-4.5 \pm \sqrt{-219.75} }{-6}$

$x=\frac{-4.5 \pm \sqrt{219.75}(\sqrt{-1} ) }{-6}$

$x=\frac{-4.5 \pm i\sqrt{219.75} }{-6}$

$x=\frac{4.5 \pm i14.824 }{6}$

$x=0.75 \pm 2.47067i$

Answer: Part A = (100% - 80%)P = 35, Part B = 140

<u>Step-by-step explanation:</u>

Percentage: Like + Don't like = 100%

80% + Don't like = 100%

<u> -80% </u> <u> -80% </u>

Don't like = 20%

People: 20% of Patrons = Don't Like

0.20 x Patrons = 35

<u>÷ 0.20 </u> <u> ÷ 0.20 </u>

Patrons = 175

<u>Now, let's write the equation we used to get that answer</u>:

Let P represent the total number of patrons, then the equation is:

(100% - 80%)P = 35

= (1.00 - 0.80)P = 35

= 0.20P = 35

= P = 175

<u>Part B: </u>

80% of Patrons = Like

0.80 x 175 = Like

140 = Like
