Find the distance between points A(2,3) and B(5,9) round to the nearest tenth

olya-2409 [2.1K]

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

$\mathsf{d=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}}$

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

$\mathsf{d=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}}\\\\ \mathsf{d=\sqrt{(5-2)^2+(9-3)^2}}\\\\ \mathsf{d=\sqrt{(3)^2+(6)^2}}\\\\ \mathsf{d=\sqrt{9+36}}\\\\ \mathsf{d=\sqrt{45}}\\\\ \mathsf{d=6.7082039324993690892275210061938...}\\\\ \underline{\mathsf{d\approxeq6.7}}$

The answer is 6.7 uc.

|x|, if x=10; .3; 0; −2.7; −9

alekssr [168]

Answer:

For $\left | x \right |$ we will have positive values only.

$\left | -2.7 |\right =2.7$

$\left | -9 |\right =9$

Rest are positive so will give positive values out of the modulus function.

Step-by-step explanation:

The absolute value of any number is its positive value only.

As for example $(-2.7)$ and $(2.7)$ both are having equal distance from $0$ in a number line, one on the left other on the right side of the number line but are equidistant from $0$ .
