Find the length of the segment that joins the points (-5, 4) and (6,-3).
Helen [10]

Answer:

\boxed {\boxed {\sf d=\sqrt{170} \ or \  d\approx 13.04}}}

Step-by-step explanation:

We are asked to find the length of a segment or the <em>distance</em> between the 2 points. The formula for distance is:

d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2

where (x₁ y₁) and (x₂, y₂) are the points. We are given the points ( -5, 4) and (6, -3). If we match the number and the corresponding variable, it is:

  • x₁= -5
  • y₁= 4
  • x₂= 6
  • y₂ = -3

Substitute the values into the formula.

d= \sqrt{(6--5)^2+(-3-4)^2

Solve inside the parentheses.

  • 6--5 (Back to back negative signs become a positive)= 6+5 =11
  • -3-4= -7

d= \sqrt{(11)^2+(-7)^2

Solve the exponents.

  • (11)²= 11*11= 121
  • (-7)²= -7*-7= 49

d= \sqrt {(121)+(49)

Add.

d= \sqrt {170}

d=13.0384048104

Even though it's not specified, we could round to the nearest hundredth to make the answer more concise. The 8 in the thousandth place tells us to round the 3 to a 4 in the hundredth place.

  • 13.03<u>8</u>4048104

d\approx 13.04

The length of the segment is <u>√170</u> or approximately <u>13.04. </u>

Gina looked at the architectural plan of a room with four walls in which the walls meet each other at right angles. The length o
Lerok [7]

For a better understanding of the solution provided here, please find the diagram attached.

In the diagram, ABCD is the room.

AC is the diagonal whose length is 18.79 inches.

The length of wall AB is 17 inches.

From the given information, we have to determine the length of the BC, which is depicted a x, because for the room to be a square, the length of the wall AB must be equal to the length of the wall BC.

In order to determine the length of the wall BC, or x, we will have to employ the Pythagoras' Theorem here. Thus:

x=\sqrt{(AC)^2-(AB)^2}

x=\sqrt{(18.79)^2-(17)^2}\approx\sqrt{64.06} \approx8

Thus, BC\approx 8 inches

\therefore AB\neq BC and hence, the given room is not a square.

A turtle can walk \dfrac{1}{12} 12 1 ​ start fraction, 1, divided by, 12, end fraction of a kilometer in an hour. The turtle is
sashaice [31]

Answer:

It will take turtle 2\frac{2}{5} \ hour to reach the pond.

Step-by-step explanation:

Given:

A turtle can walk 1/12 of a kilometer in an hour.

The turtle is 1/5 of a kilometer away from a pond.

Now, to find the time it will take the turtle to reach the pond.

<u>Speed</u> of turtle  =  \frac{1}{12}\ kilometer\ per\ hour.

<u>Distance</u> of turtle from the pond =  \frac{1}{5} \ kilometer.

Now, to get the time it will take turtle to reach the pond we put formula:

Time=\frac{Distance}{speed}

Time=\frac{\frac{1}{5}}{\frac{1}{12}}

Time=\frac{1}{5} \times \frac{12}{1}

Time=\frac{12}{5}

Time=2\frac{2}{5}\ hour.

Therefore, it will take turtle 2\frac{2}{5} \ hour to reach the pond.
