The distance AB rounded to the nearest tenth

Mathematics
1 answer:
Sladkaya [172]4 years ago
6 0

Answer:

Step-by-step explanation:

Givens

A = -2,1

B= 1,-1

Solution

AB = sqrt(  (-2 -   -1)^2 + (1 - -1)^2 )

AB = sqrt(  (-2 + 1)^2 + (1 + 1)^2 )

AB = sqrt(  (-1)^2 + 2^2)

AB = sqrt (1 + 4)

AB = sqrt(5)

What is the length of BC in the right triangle below?
Verdich [7]

Answer:

<h2>BC = 39</h2>

Step-by-step explanation:

Use the Pythagorean theorem:

hypotenuse^2=leg^2+leg^2

We have

leg=AC=36,\ leg=AB=15, hypotenuse=BC

Substitute:

BC^2=36^2+15^2\\\\BC^2=1296+225\\\\BC^2=1521\to BC=\sqrt{1521}\\\\BC=39

Sara is working on a Geometry problem in her Algebra class. The problem requires Sara to use the two quadrilaterals below to ans
zloy xaker [14]
Part A:

Given a square with sides 6 and x + 4. Also, given a rectangle with sides 2 and 3x + 4

The perimeter of the square is given by 4(x + 4) = 4x + 16

The area of the rectangle is given by 2(2) + 2(3x + 4) = 4 + 6x + 8 = 6x + 12

For the perimeters to be the same

4x + 16 = 6x + 12
4x - 6x = 12 - 16
-2x = -4
x = -4 / -2 = 2

The value of x that makes the <span>perimeters of the quadrilaterals the same is 2.



Part B:

The area of the square is given by

Area=(x+4)^2=x^2+8x+16

The area of the rectangle is given by 2(3x + 4) = 6x + 8

For the areas to be the same

x^2+8x+16=6x+8 \\  \\ \Rightarrow x^2+8x-6x+16-8=0 \\  \\ \Rightarrow x^2+2x+8=0 \\  \\ \Rightarrow x= \frac{-2\pm\sqrt{2^2-4(8)}}{2}  \\  \\ = \frac{-2\pm\sqrt{4-32}}{2} = \frac{-2\pm\sqrt{-28}}{2}  \\  \\ = \frac{-2\pm2i\sqrt{7}}{2} =-1\pm i\sqrt{7}

Thus, there is no real value of x for which the area of the quadrilaterals will be the same.
