Find the distance from (7, 4) and (-1,-4) A. 11.31 B. 8 C. 10.42 D. 9.76

Neko [114]

Answer:

Step-by-step explanation:

Calculate the distance using the distance formula

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

with (x₁, y₁ ) = (7, 4 ) and (x₂, y₂ ) = (- 1, - 4 )

d = $\sqrt{(-4-4)^2+(-1-7)^2}$

= $\sqrt{(-8)^2+(-8)^2}$

= $\sqrt{64+64}$

= $\sqrt{128}$

≈ 11.31 ( to 2 dec. places )

Solve the following quadratic function by utilizing the square root method. y = 16 – x2

xxMikexx [17]

Answer:

The solutions are x = -4 and x = 4.

Step-by-step explanation:

Solving a quadratic equation:

We have to find x for which $y = 0$ .

In this question:

$y = 16 - x^2$

$16 - x^2 = 0$

$x^2 = 16$

$x = \pm \sqrt{16}$

$x = \pm 4$

The solutions are x = -4 and x = 4.
