What is the discriminant of 9x^2+2=10x

Mathematics
2 answers:
nadezda [96]3 years ago

Answer:

28.

Step-by-step explanation:

9x^2 + 2 = 10x

9x^2 - 10x + 2 = 0

The discriminant is b^2 - 4ac.

In this case, a = 9, b = -10, and c = 2.

(-10)^2 - 4 * 9 * 2

= 100 - 36 * 2

= 100 - 72

= 28.

Since the discriminant is positive, there are two real solutions to the function.

Hope this helps!

Wendy throws a dart at this square-shaped target:
Ostrovityanka [42]

Answer:

Hello! I hope I am correct! :)

Step-by-step explanation:

Let’s first calculate the black circle & the white space.

Since there is more white space than the black circle, we already know that the white space will have more probability.

These are the steps you need to do, in order to so love this problem:

1. Find the area of both, the white space and the black circle.

2. Divide both of them by the area of the square.

3. Do all these steps to find the probability/hitting.

Part A:

Black circle: ( π *1^2) / ( π 5^2) = 1/25 = .04 or 3.14% chance.

So we can tell it’s close to zero.

Part B: 1 - .04 = 0.96 or 97%

This is close to one.

(Remember I am not saying the exact, it’s a estimate)

Brainliest would be appreciated!

Hope this helps! :)

katrin2010 [14]

Answer:

C. Four less than the product of two and a number is less than the product of four and the same number increased by eight.

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Converting expressions to word form

Step-by-step explanation:

<u>Step 1: Define</u>

2x - 4 < 4x + 8

<u>Step 2: Translate</u>

"2x" is the product of two and a number <em>x</em>

" - 4" is four less

"<" is less than

"4x" is the product of four and a number <em>x</em>

" + 8" is increased by 8

<u>Step 3: Combine</u>

The difference between the product of two and a number <em>x</em> and 4 is less than the sum of the product of four and a number <em>x</em> and 8.

<u>Step 4: Reword</u>

Four less than the product of two and a number is less than the product of four and the same number increased by eight.

Divide each side of the inequality by "6" ;

   to isolate "x" on one side of the inequation; & to solve in terms of "x" ;

                 →  " 6x  / 6  >  12 / 6  "  ;

   to get:

                 →  "  x  >  2 " .
