Answer:

The perfect square ( x -1 )² = 2

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given equation  x² - 2 x = 1

              ⇒        x² - 2 x + 1 -1 = 1

             ⇒        x² - 2x + 1² = 1 +1

             ⇒     ( x -1 )² = 2

A certain lottery​ game, 32 numbers are randomly mixed and 7 are selected. A person must pick all 7 numbers to win. Order is not
lorasvet [3.4K]

Answer:

Below.

Step-by-step explanation:

The number of combinations of 7 from 32 =  32! / 7! (32-7)!

= 3365856

So it is 1/ 3365856 = 0.000000297

or about 3 in 10,000,000.

Triangle has sides 7 inches, 7.5 inches, and x inches. What is the range of possible lengths for side x, in inches?
jarptica [38.1K]

Answer:

<em>0.5 < x < 14.5</em>

Step-by-step explanation:

<u>Triangle Inequality Theorem </u>

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining those inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given two of the triangle side lengths as y=7.5 and z=7, thus the third side length (x) can be in the range:

7.5 - 7 < x < 7.5 + 7

0.5 < x < 14.5

<u>Note: The latter is the correct answer but none of the choices is accurate. Choice D is closer to the correct answer but the endpoints cannot be included.</u>

Answer:

Hello! Your answer would be BELOW

Step-by-step explanation:

In the history of education the one-room schoolhouse has played an important role in several countries. In the rural areas of the US Midwest and in Norway the one-room schoolhouse was the most common school in the second half of the nineteenth century and the first decades of the twentieth. Although the schoolhouses at first sight seem identical there are some interesting points of distinction in their educational history and how their legacy is interpreted, managed, preserved and promoted today. In the Midwest they are a beloved national icon, often listed, embodying national values and virtues. In Norway their story is effectively untold, not a single one is listed on national preservation lists and by no means do they embody national identity, virtues or values. This article offers an explanation for this different treatment.

Hope I helped! Ask me anything if you have questions! Brainiest plz. Hope You make a 100%! Have a nice day! -Amelia♥

a bicyclist is going 200m/s. after 10 seconds the bicyclist is going 150m/s. what is his acceleration
mote1985 [20]

Acceleration:  rate of change of velocity with time.

Here, that acceleration is:


100 m/s - 150 m/s

----------------------------

     10 sec

= (-150 m/s) / (10 sec) = - 15 meters per second squared
