Answer:

80, 40, 40

Step-by-step explanation:

The rule is if the number before the tens place is 5 or more round up and if it is 4 or less round down.

I like to look at it without the rule and what makes sense.

82.14:  my choices are 80 or 90.  What number is 82.14 closer to on the number line?  80.

38.5  The choices are 30 and 40.  This number on a number line would be closer to 40

41.3  The choices are 40 and 50.  On a number line this number would be closer to 40.

Consider the vector add = a + b = [13 12 11 10 10] and sub = a - b = [-11 - 6 - 14 8]. Find the vector a and b.
prisoha [69]

Answer:

a = [1   3   5   7   9] and b = [12   9   6   3   1]

Step-by-step explanation:

The addition of two vectors a and b is defined as

a + b = [13   12   11   10   10]                .... (1)

The subtraction of two vectors a and b is defined as

a - b = [-11   - 6   - 1   4    8]                 .... (2)

After adding (1) and (2), we get

(a + b) + (a - b)= [13   12   11   10   10] + [-11   - 6   - 1   4    8]

On simplification we get

2a = [13-11   12-6   11-1   10+4   10+8]

2a = [2   6   10   14   18]

Divide both sides by 2.

a = [1   3   5   7   9]

Substitute the value of vector a in equation (1).

[1   3   5   7   9] + b = [13   12   11   10   10]

Subtract vector a from both sides.

b = [13   12   11   10   10] - [1   3   5   7   9]

On simplification we get

b = [13-1   12-3   11-5   10-7   10-9]

b = [12   9   6   3   1]

Therefore the vectors a and b are defined as a = [1   3   5   7   9] and b = [12   9   6   3   1].

Two non-perpendicular, non-bisecting, intersecting line segments definition
hichkok12 [17]
Line segments are parts of line that have fixed ends. For them to be perpendicular, the angle between them should be 90°. Bisecting lines are those that cut each other into two equal parts. If the lines intersect but the conditions above are not satisfied then, the lines are non-perpendicular and non-bisecting, intersecting lines.
