What is the distance between (-5, 5) and (1, -2)
Murrr4er [49]

Answer:

\displaystyle d=\sqrt{85}\text{, or about 9.22 units}

Step-by-step explanation:

          We will use the distance formula to solve.

\displaystyle d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}

\displaystyle d=\sqrt{(1--5)^2 +(-2-5)^2}

\displaystyle d=\sqrt{(6)^2 +(-7)^2}

\displaystyle d=\sqrt{36+49}

\displaystyle d=\sqrt{85}\text{, or about 9.22 units}

Which statement about the following equation is true?<br>2x2-9x+2-1​
Furkat [3]

Complete Question:

Which statement about the following equation is true?

2x^2-9x+2 = -1

A) The discriminant is less than 0, so there are two real roots

B) The discriminant is less than 0, so there are two complex roots

C) The discriminant is greater than 0, so there are two real roots

D) The discriminant is greater than 0, so there are two complex roots

Answer:

C) The discriminant is greater than 0, so there are two real roots

Step-by-step explanation:

The given equation is 2x^2-9x+2 = -1 which by simplification becomes

2x^2 - 9x + 3 = 0

For a quadratic equation of the form ax^2 + bx + c = 0, the discriminant is given by the equation, D = b^2 - 4ac

If the discriminant D is greater than 0, the roots are real and different

If the discriminant D is equal to 0, the roots are real and equal

If the discriminant D is less than 0, the roots are imaginary

For the quadratic equation under consideration, a = 2, b = -9, c = 3

Let us calculate the discriminant D

D = (-9)² - 4(2)(3)

D = 81 - 24

D = 57

Since the Discriminant D is greater than 0, the roots are real and different.

Which best describes the graph of g(x) = 1/9 sq x<br> PICTURE DOWN BELOW
Alexus [3.1K]

Answer:

A) The graph of g(x) is shrunk vertically by a factor of 1/9

Step-by-step explanation:

The given graph g(x) = 1/9√x

f(x) = √x

The altitude of g(x) = 1/9

The altitude of f(X) = 1

When comparing the graph of g(x) with f(x), the graph of g(x) shrunk by 1/9 because of the altitude.

Here with I have attached the graph.

Therefore, answer: A) The graph of g(x) is shrunk vertically by a factor of 1/9

Thank you.
