Which theorem is the following?

lord [1]

Answer:

Perpendicular bisector theorem

Step-by-step explanation:

The illustration of the theorem is:

If point B is a perpendicular bisector of Line AC and the length of AC is 10cm

Then

$AB + BC = 10$

Where

$AB = BC$ --- Perpendicular bisector

So, the equation becomes

$AB + AB =10$

$2AB =10$

$AB = 5$

Recall: $AB = BC$

$AB = BC = 5$

Mark rolls 2 fair dice and adds the results from each.

Natali5045456 [20]

Answer:

P ( X > 5 ) = 72,2 %

Step-by-step explanation:

The probability of success ( outcomes bigger than 5 )

If dice 1 outcome is 6 no matter wich outcome we get from dice 2 all events are successful, the we have 6 outcomes

If dice 1 outcome is 5 we also have 6 outcomes

If dice 1 outcomes is 4 we have 5 positive outcomes

If dice 1 outcome is 3 we have 4 positive outcomes

If dice 1 outcome is 2 we have 3 positive outcomes

if dice 1 outcome is 1 we have 2 positive outcomes

Total evaluating dice 1: positive outcomes 26

We will get the sames results analysing dice 2 then we have a total of

52 successful events

And total numbers of outcomes is 36 + 36 = 72

Then

P ( X > 5 ) = 52/72

P ( X > 5 ) = 0,722

P ( X > 5 ) = 72,2 %

Ln (1/x)+ln (2x^3)=ln3

Lapatulllka [165]

$\ln \frac{1}{x} +\ln2x^3=\ln3$
$\ln \frac{2x^3}{x} = \ln3$
$\ln2x^2=\ln3$
$2x^2=3$
$x=\sqrt{ \frac{3}{2} }$

HELPPPPPPPPPPP<br> Draw the graph of y = 2x + 3 on the grid

topjm [15]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y=2x+3$

This is the equation of the line

To graph a line we need two points

<em>Find the intercepts</em>

1) The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=2(0)+3$

$y=3$

The y-intercept is the point (0,3)

2) The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=2x+3$

$x=-3/2=-1.5$

The x-intercept is the point (-1.5,0)

To draw the graph of the line plot the intercepts and join the points

using a graphing tool

see the attached figure
