Answer 2

Answer:

[tex]x = \frac{ 1 + 1\sqrt{-1}}{3}[/tex] and [tex]x = \frac{ 1 - 1\sqrt{-1}}{3}[/tex]

Step-by-step explanation:

Hello!

The quadratic formula is: [tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex], derive from the standard form of a quadratic: [tex]ax^2 + bx + c[/tex].

The expression 3x² - 2x + 1 is a lot like our standard form:

a = 3b = -2c = 1

Let's plug in the values and solve.

Solve the Quadratic Formula:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4(2)(1)}}{2(3)}[/tex][tex]x = \frac{2 \pm\sqrt{4 - 8}}{6}[/tex][tex]x = \frac{2 \pm \sqrt{-4}}{6}[/tex][tex]x = \frac{2 \pm 2\sqrt{-1}}{6}[/tex][tex]x = \frac{ 1 \pm 1\sqrt{-1}}{3}[/tex]

The roots are [tex]x = \frac{ 1 + 1\sqrt{-1}}{3}[/tex] and [tex]x = \frac{ 1 - 1\sqrt{-1}}{3}[/tex]

There were 350 apples on the tree in March. By September there were 420 apples on the tree.
What was the percentage of change of apples on the tree? Round your answer to the nearest
tenth. *

Answers

Answer:

Step-by-step explanation:

20%

Answer:

The correct answer is 20.0% increase.

Step-by-step explanation:

In this situation, you would need to find how to find the percentage of change.

Therefore, you will need to first use subtraction, division and then multiplication to justify your answer.

--

First, find out how much the original number increased by.

[tex]420-350=70[/tex]

Next, divide the 70 with the original number, which is 350.

[tex]7[/tex] ÷ [tex]350=0.2[/tex]

Finally, to turn your decimal into a whole number, multiply by 100.

[tex]0.2[/tex] × [tex]100=20[/tex]

Remember to add the percent (%) symbol after receiving your final product.

Determine the intercepts of the line. Do not round your answers. 2 x + 5 y = − 6

Answers

The y-intercept for the line, 2x + 5y = -6, is: 1.2.

Equation of a Line in Slope-Intercept FormThe equation of a line can be represented in slope-intercept form as: y = mx + b."b" is the y-intercept.

Given:

2x + 5y = -6

Rewrite in slope-intercept form

5y = -2x - 6

Divide both sides by 5

y = -2/5x - 6/5

"b" = -6/5 = 1.2

Therefore, the y-intercept for the line, 2x + 5y = -6, is: 1.2.

Answer:

No, she isn't

Step-by-step explanation:

(-2)² is basically -2 x -2, which we know is 4.

-2² is slightly different. In this case, you don't consider it as the square of -2, but you do the square ignoring the negative sign, and then add it at the end.

So think about it like this,

We do 2² first, and then add the minus, so it becomes -4 instead of positive 4. Does that make sense?

Answer: Incorrect

Step-by-step explanation:

Rule :

[tex](-10)^2=| -10|^2 =100 \\\\ -10^2=-(10)^2=-|10|^2=100[/tex]
