Answer:

c = 8.5

Step-by-step explanation:

a² + b² = c²

8² + 3² = c²

64 + 9 = c²

c² = 73

$\sqrt{c^2} =\sqrt{73}$

c = 8.5

Answer:

The length of the line segment is of 5.9 units.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, $(x_1,y_1)$ and $(x_2,y_2)$ . The distance between these two points is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

How long is the line segment?

The distance between points P and Q. So

P(1,3), and Q(4,8).

$D = \sqrt{(4-1)^2+(8-3)^2} = \sqrt{3^2 + 5^2} = \sqrt{34} = 5.9$

The length of the line segment is of 5.9 units.

The sum of a number and its reciprocal is 13/6. find the number

Anna71 [15]

$x + \frac{1}{x} = \frac{13}{6} \text{, x} \neq 0$
$x^{2} - \frac{13}{6}x + 1 = 0$
$6x^{2} - 13x + 6 = 0$
$6x^{2} -9x - 4x + 6 = 0$
$3x(2x - 3) - 2(2x - 3) = 0$
$(3x - 2)(2x - 3) = 0$

So, the numbers are: 3/2 and 2/3
