The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c

Find the equation of the line that is parallel to y=5x+1 and passes through the point (10, -1)
DaniilM [7]

Answer:

<em>The</em><em> </em><em>required</em><em> </em><em>equation</em><em> </em><em>is</em><em> </em><em>5x-y-51</em><em> </em><em>=</em><em> </em><em>0</em>

Step-by-step explanation:

the \: given \: equation \: is \\ y = 5x + 1 \\ 5x - y + 1 = 0 \\ the \: equation \: of \: the \: line \: \\  parallel \: to \: 5x - y + 1 = 0 \:  \: is \\ 5x - y + k = 0 \\ since \: it \: passes \: through \: (10, - 1) \\ 5(10) - ( - 1) + k = 0 \\ 50 + 1 + k = 0 \\k  =  - 51 \\ the \: equation \: of \: the \: line \: parallel \: t o\:  \\ 5x - y + 1 = 0 \:  \:  \: is  \\ \: 5x - y - 51 = 0

Is -3 a natural number a whole number a integer a rational number or irrational number
BaLLatris [955]

Answer:

-3 is a rational integer.

Step-by-step explanation:

An integer is a superset of the whole numbers that includes the negated values as well as 0.

A rational number is simply anything that can be expressed as a fraction.

-3 is by these definitions, a negated 3, and any non fractional number can be expressed as a fraction.

-3 is not a natural number, as that is the set of numbers {1, 2, 3, 4, 5, ... etc} and -3 is not a whole number, as that is the set of numbers {0, 1, 2, 3, 4, ... etc}.

And -3 is also not an irrational number since it can be expressed as a fraction.

Thus, -3 is a rational integer.

Cheers.

Write an equation for each line (use the picture)
loris [4]

Answer:

Red Line: y=4

Blue Line: y=-2

Green Line: x=-1

Yellow Line: x=6

Step-by-step explanation:

Red line: the line crosses through 4 on the y axis. Therefore, y=4.

Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.

Green line: the line crosses through -1 on the x axis. Therefore, x=-1.

Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.

This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!
