Determine whether a figure with the given vertices is a rectangle using the distance formula.
a(4, –7), b(4, –2), c(0, –2), d(0, –7)
question 14 options:
yes; opposite sides are congruent.
yes; opposite sides are congruent, and diagonals are congruent.
yes; opposite sides are parallel.
no; opposite sides are congruent, but diagonals are not congruent.

Yes; Opposite sides are congruent, and diagonals are congruent.

Step-by-step explanation:

we have

we know that

the formula to calculate the distance between two points is equal to

step 1

Find the length of the sides

Find the distance AB

substitute the values

Find the distance BC

substitute the values

Find the distance CD

substitute the values

Find the distance AD

substitute the values

Compare the length sides

AB=CD

BC=AD

therefore

Opposite sides are congruent

step 2

Find the length of the diagonals

Find the distance AC

substitute the values

Find the distance BD

substitute the values

Compare the length of the diagonals

AC=BD

therefore

Diagonals are congruent

The figure is a rectangle, because Opposite sides are congruent, and diagonals are congruent

The correct option is 2.

Step-by-step explanation:

Given information: A(4, –7), B(4, –2), C(0, –2), D(0, –7).

Distance formula:

Using distance formula we get

Length of sides are

Similarly,

Length of diagonals are

It figure ABCD,

1. AB and CD are opposite sides.

2. BC and AD are opposite sides.

3. AC and BD are diagonals.

From the above calculations it is clear that opposite sides are congruent, and diagonals are congruent. So, the figure ABCD is a rectangle.

Therefore the correct option is 2.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
