Answer:

The perimeter of triangle ΔABC is approximately;

(A) 20.0

Step-by-step explanation:

In ΔABC, the coordinates of the vertices are given as follows;

A(-4, 1), B(-2, 3), C(3, -4)

The length, 'l', of the sides of the triangle with known 'x', am]nd 'y' coordinates are given as follows;

l = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Therefore, we have;

The length of segment \overline {AB} = √((3 - 1)² + (-2 - (-4))²) = 2·√2 ≈ 2.83

The length of segment \overline {BC} = √(((-4) - 3)² + (3 - (-2))²) = √74 ≈ 8.6

The length of segment \overline {AC} = √(((-4) - 1)² + (3 - (-4))²) = √74 ≈ 8.6

The perimeter of a geometric shape is equal to the sum of the length of sides of the figure

The perimeter of triangle ΔABC = (The length of segment \overline {AB}) + (The length of segment \overline {BC} ) + (The length of segment \overline {AC})

∴ The perimeter of triangle ΔABC = 2·√2 + √74 + √74 ≈ 20.0.

Does anyone know the answer?
SSSSS [86.1K]

Answer:

12

Step-by-step explanation:

a2+b2=c2 since the hypotenuse is 13 you would square it to get 169 and then you would square 5 and get 25 you would subtract 169-25 and get 144 then you would square root that number and get 12 so then your answer is 12 in.

Select the correct vectors.
Paha777 [63]

In the case above, the correct vectors are:

  • <25.98, -15>.
  • <1.71, 4.7>.

<h3>What is the ship vector about?</h3>

The solution for the Ship's vector are:

Note that the Horizontal aspect = 30 cos 30  

                                                   = 25.98.

For the  Vertical aspect = 30 sin(-30)

                                        = -15.

Hence it will be  <25.98, -15>.

In regards to the current's vector:

The Horizontal aspect=  5 sin 20

                                       = 1.71.

The Vertical aspect = 5 cos 20

                                     = 4.7.

Hence it will be <1.71, 4.7>.

Therefore, In the case above, the correct vectors are:

  • <25.98, -15>.
  • <1.71, 4.7>.

Least to greatest 0.94,9.40,0.094,94.0,94.0
sertanlavr [38]
Here's an example number:
123.456
The place values are, from greatest to least:
The 1 is in the <em /><em>hundreds</em> place
The 2 is in the <em /><em>tens</em> place
The 3 is in the <em>ones</em> place
The 4 is in the <em>tenths</em> place
The 5 is in the <em>hundredths </em>place

If you have some number like 9.40 with no decimal point, shifting it will change the value. Moving the decimal one place to the right multiplies the value by ten. (94)
Moving it one place to the rigt divides it by ten. (0.94)

Here's our list from least to greatest:
94.0
9.40
0.94
0.094
