Dimas [21]2 years ago
3 0

Answer:

4\sqrt{2}

Step-by-step explanation:

distance formula:\sqrt{\left(x_2-x_1\right)^{2}+\left(y_2-y_1\right)^{2}}

set square to be centered on the origin and find the distance between 2 of the connected points

\sqrt{\left(3-2\right)^{2}+\left(2-1\right)^{2}}

= \sqrt{\left(1\right)^{2}+\left(1\right)^{2}}

= \sqrt{2}

multiply by 4 as it is a square and all of its sides are equal

4\sqrt{2}

insert units

4\sqrt{2}\ \ meters

n200080 [17]

Answer:

2580 degrees rotated per second

Step-by-step explanation:

since  you have to find the degrees it rotates per second.

you need to divide 430 by 60 to find rotations per second

1)          430/60

             =  7.16666667 rotations per second

-then you have to multiply it by 360 degrees ,because their is 360 degrees in a circle

2)        7.16666667 (360)

            =  2580 degrees rotated per second

Writing and Solving an Equation to Find Negative Integers Two negative integers are 5 units apart on the number line, and their
Shtirlitz [24]

Answer:

-23

Step-by-step explanation:

Let first negative integer = x

The second = x +5

Their product = 126, hence,

x * (x +5) = 126

x^2 + 5x = 126

x^2 + 5x - 126 = 0

Two numbers whose product gives - 126 and sun gives 5

x(x + 14) - 9(x+14) =0

(x - 9) = 0 or (x + 14) = 0

x = 9 or x = - 14

Since x is said to be a negative integer,, the our x = - 14

First integer = - 14

Second integer = (x + 5) = (-14 + 5) = - 9

Sum of both integers :

-14 + - 9 = - 23

Which inequality represents the sentence below? The difference of a number and one and four tenths is more than nine and seventy
Marianna [84]

The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

Before solving it, first let's discuss the tenth and hundredths,

  • Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
  • Hundredths is written as the fractional part of the number 100. The value of one hundredth is equal to 1/100 or 0.01.

Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

One and four tenths can be written as,

1\dfrac{4}{10}

Nine and seventy-eight hundredths can be written as,

9\dfrac{78}{100}

Let suppose the number is <em>p</em>. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,

p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\

Hence, the inequality represents the sentence below is that the p minus 1. 4 greater-than 9.
