Solve the quadratic equation by using a numeric approach. x squared + 1.1 x minus 2 = 0 a. x = 1.7 and x = -29.2 c. x = 2.3 and

Korolek [52]

Answer:

None of the options are correct, the correct answers are: x = 0.967 and -2.067

Step-by-step explanation:

$x^2 + 1.1x - 2 = 0$

Comparing this equation with $ax^2 + bx + c = 0$

a = 1, b = 1.1, c = -2

Using the almighty formula for solving quadratic equation:

$x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a} \\x = \frac{-1.1 \pm \sqrt{1.1^2 - 4(1)(-2)} }{2(1)} \\x = \frac{-1.1 \pm \sqrt{1.1^2 - 4(1)(-2)} }{2(1)} \\x = \frac{-1.1 \pm 3.035 }{2}\\x_1 = \frac{-1.1 + 3.035 }{2} = 0.967\\x_2 = -\frac{-1.1 - 3.035 }{2} = -2.067$

Can you please Solve for x and y

hichkok12 [17]

Answer:

x = 35, y = 26.5

Step-by-step explanation:

x = 35 ( Alternate angles are congruent )

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2y - 10 + 35 + 102 = 180, that is

2y + 127 = 180 ( subtract 127 from both sides )

2y = 53 ( divide both sides by 2 )

y = 26.5

* ae. This number in unit form is all mixed up! Convert it to standard form. 4 hundred thousands 16 thousands 4 hundreds 21 tens

DiKsa [7]

Answer: 416, 622

Step-by-step explanation:

First, let's look at the hundred thousands place.

We have 4 hundred thousand, which can be rewritten as 400,000.

Then, we have our ten thousand place in which we have sixteen thousand, which can be rewritten as 16,000.

Next, we have our hundreds place. Here, we have four-hundred, or 400.

After that, we have 21 tens, which can be rewritten as 210.

Lastly, we have 12 ones.

Now, if we add all of these together, we get:

400,000 + 16,000 + 400 + 210 + 12 = <em>416,622</em>

(Hope this helps!)
