Someone pls help! i’m confused since i’ve never done this problem before

Answer:

Step-by-step explanation:

The midpoint of the line is just the midpoint (average) of each pair of x, y, and z

2a ((-4 + 5)/2, (4 - 1)/2, (3 + 3)/2) = (0.5, 1.5, 3)

2b ((-5.1 + 1.4)/2, (-2 + 1.7)/2, (9 + 11)/2) = (-1.85, -0.15, 10)

The distance between points is the root of the sum of squares of the difference between each x, y, and z.

3a √((2 - 4)² + (3 - 3)² + (5 - 1)²) = √20 = 2√5

3b √((-3 - 2)² + (7 - 4)² + (2 - (-1))²) = √43

Give a recursive definition of each of these sets of ordered pairs of positive integers. [Hint: Plot the points in the set in th

konstantin123 [22]

Answer:

(2,1), (1,2) is your base step

if (a,b) is in the set (a+1,b+1) will be in the set

if (a,b) is in the set (a+2,b) will be in the set

if (a,b) is in the set (a,b+2) will be in the set.

Step-by-step explanation:

Think about how to solve this problem in general. How can you assure that the sum a+b is odd ?

Think about this, what happens when you sum two even numbers ? The result is even or odd ?

2+6 = 8 (even )

10+12 = 22 (even)

And what happens when you sum two odd numbers ? The result will be even or odd ? Look

3+7 = 10 (even)

5+11 = 16 (even)

Therefore to assure that a+b is odd, one of them has to be odd and one of them has to be even, that is why

(2,1), (1,2) is your base step

if (a,b) is in the set (a+1,b+1) will be in the set

if (a,b) is in the set (a+2,b) will be in the set

if (a,b) is in the set (a,b+2) will be in the set.
