The distance formula is: d = sqrt( (x2 - x1)2 + (y2 - y1)2 )

For this problem, let (-5, -4) be the "first" point, so x1 = -5 and y2 = -4

and let (-6, 4) be the "second" point, so x2 = -6 and y2 = 4.

Then: d = sqrt( (-6 - -5)2 + (4 - -4)2 ) = sqrt( (-1)2 + (8)2 ) = sqrt( 1 + 64 ) = sqrt( 65)

The distance formula is just the Pythagorean Theorem applied to an x-y graph.

You would get the same final answer if you let (-5, -4) be the second point and (-6, 4) be the first point.

Find the midpoint of the line segment joining the points (5,6) and (-1,-6).

kumpel [21]

Answer:

The midpoint is (2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(5+-1)/2 =4/2 =2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(6+-6)/2 =0/2 =0

The midpoint is (2,0)

Consider the expression 3 * 2 ^ 2 < 16 + 5 andalso 100 / 10 * 2 > 15 - 3. which operation is performed second

BartSMP [9]

3 * 2 ^ 2 < 16 + 5
should be performed in the order PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)/
Therefore, obtain
3 * 2 ^ 2 < 16 + 5
3 * 4 < 16 + 5 Exponentiation first
12 < 16 + 5 Multiplication second

Similarly, obtain
100 / 10 * 2 > 15 - 3
100 / 20 > 15 - 3 Multip[lication first
5 > 15 - 3 Division second

Separate the number 219 into three parts. The second number is two less than 5 times the first number, and the third number is 4

Sav [38]

Let us assume the first number = x
Then the second number = 5x -2
The third number = x + 4
The total number that needs to be divided into three parts is 219
Then we can write the equation as
x + 5x - 2 + x + 4 = 219
7x + 2 = 219
7x = 219 - 2
7x = 217
x = 217/7
= 31
Then
First number = 31
Second number = 5x - 2
   = (5 * 31) - 2
   = 155 -2
= 153
Third number = x + 4
   = 31 + 4
   = 35
So the three numbers are 31, 153 and 35.
