8. A cable car travels 2236 m to climb a mountain that is 1000 m high. It then travels 1414 m to descend 1000 m on the other sid

frutty [35]

Answer:

3000 m

Step-by-step explanation:

Using Pythagoras theorem

$2236^2=1000^2+|AB|^2\\|AB|^2=2236^2-1000^2\\|AB|^2=3999696\\|AB|=\sqrt{3999696} \\=1999.9$

Similarly

$1414^2=1000^2+|BC|^2\\|BC|^2=1414^2-1000^2\\|BC|^2=999696\\|BC|=\sqrt{999696} \\=999.7m$

Length of the Tunnel = |AB|+|BC|

=1999.9+999.7

=2999.6

=3000 m

Is x=4 and y=5 perpendicular

faltersainse [42]

True!

<h2>Explanation:</h2>

The Cartesian coordinate system is formed by two perpendicular axes, which are the x-axis and y-axis. In this problem, we are given two lines:

$x=4 \ and \ y=5$

The line $x=4$ is parallel to the y-axis and has an undefined slope.
The line $y=5$ is parallel to the x-axis and has a slope of zero.

Since the x and y-axes are perpendicular, then the lines $x=4 \ and \ y=5$ are also perpendicular.
