Answer: Second option.


Step-by-step explanation:

 1. To solve this problem you can applly the quadratic formula, which is shown below:

 x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. The quadratic  equation is:

x^{2}-10x+25-35=0\\x^{2}-10x-10=0

3. Then:

a=1

b=-10

c=-10

4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:

x=\frac{-(-10)+/-\sqrt{(-10)^{2}-4(1)(-10)}}{2(1)}

x=5±√35

Answer:

option B). x = [5 ± √35] is the correct answer

Step-by-step explanation:

<u>Formula:- </u>

for a quadratic equation ax² + bx + 0 = 0

x = [-b ± √(b² - 4ac)]/2a

<u>To find x </u>

Here  quadratic equation be,  x² - 10x +25 = 35

⇒  x² - 10x + 25 - 35 = 0

⇒   x² - 10x -10 = 0

a = 1, b = -10 and  c -10

x = [-b ± √(b² - 4ac)]/2a

x = [-(-10) ± √((-10²) - 4*1*(-10))]/2*1

x = [10 ± √(100 + 40)]/2

x = [10 ± √(140)]/2

x = [10 ± 2√35]/2

x = [5 ± √35]

Therefore option B). x = [5 ± √35] is the correct answer

Write the equation of a polynomial of degree 3, with zeros 1, 2 and -1 where f(0)=2
ser-zykov [4K]

Answer:

f(x) = x^3 - 2x^2 - x + 2

Step-by-step explanation:

since the zeroes are 1,-1, and 2. we can write the function like

f(x) = (x-1)(x+1)(x-2)

f(x) = (x^2-1)(x-2)

f(x) = x^3 -2x^2 -x +2

and it is true that f(0)=2

Write this number in expanded form 382,706
77julia77 [94]

Answer:

Expanded form : 300,000 +80,000 +2000 +700 +6.

Step-by-step explanation:

Given  : 382,706.

To find : Write this number in expanded form.

Solution : We have given  382,706.

We can  see 3 is at hundred thousand place = 300,000

8 is at ten thousand place = 80,000.

2 is at thousand place  = 2000.

7 is at hundred place  = 700.

6 is at ones place = 6

Then

Expanded form : 300,000 +80,000 +2000 +700 +6.

Therefore, Expanded form : 300,000 +80,000 +2000 +700 +6.

Order six and three tenths repeating, negative six and four ninths, 630%, and −6.1 from least to greatest.
NNADVOKAT [17]

The order of six and three tenths repeating, negative six and four ninths, 630%, and −6.1 from least to greatest is negative six and four ninths, −6.1, 630%, six and three tenths repeating. option D

<h3>Ascending order</h3>

This is the arrangements of numbers from the least to the greatest, that is, from lower value to higher value.

six and three tenths repeating

= 6.333

negative six and four ninths

= -6 4/9

= -6.444

630%

= 630/100

= 6.3

−6.1

From least to greatest:

  • negative six and four ninths
  • −6.1
  • 630%
  • six and three tenths repeating

Therefore, the order six and three tenths repeating, negative six and four ninths, 630%, and −6.1 from least to greatest is negative six and four ninths, −6.1, 630%, six and three tenths repeating. option D
