Answer:

The last one

Step-by-step explanation:

If you were to multiply each of the numbers by 10, you would get

9cm, 12cm, 15cm.

If you divide by 3,

3cm, 4cm, 5cm.

That is a 3-4-5 triangle, and that is a pythagoren triple.

Since we mulitplied and divided the same for all 3 numbers, it still works for the original triangle (0.9, 1.2, 1.5)

Solve y=-3x² + 4.5x – 20 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

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

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

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

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

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

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

$x=0.75 \pm 2.47067i$
