A cable is 84 meters long, it is cut into two pieces so that one piece is 18 meters longer than the other. Find the length of ea
weeeeeb [17]

Long Piece: x + 18

Short Piece: x

(x) + (x + 18) = 84

2x + 18 = 84

2x = 66

x = 33

Long Piece: x + 18  = (33) + 18   = 51

Answer: 33 meters and 51 meters

Find the slope of the line whose equation is 2x – 4y = 10.<br><br> How do I find the slope?
yulyashka [42]
To find the slope, u need to put the equation in y = mx + b form, where m will be ur slope.

2x - 4y = 10 ... subtract 2x from both sides
-4y = -2x + 10...divide both sides by -4
y = (-2/-4)x + (-10/4)
y = 1/2x - 5/2

y = mx + b
y = (1/2)x - 5/2
the slope(m) = 1/2

The length of chord AB in D is 9mm. If the measure of angle AB is 32 then find the length of AB
Taya2010 [7]
The length of arc AB is 9.12 mm:

We first calculate for the radius r of the circle using the equation
     r = c/(2 sin[theta/2]) 

     where c is the length of chord AB that is given as 9 millimeters
                angle given is 32 degrees

To convert theta 32 degrees into radians:
     32 degrees * (pi/180) = 32 degrees * (3.14/180) = 0.5583 radians

We now substitute the values into the equation to find the radius r:
     r = 9/(2 sin[0.5583/2]) 
     r = 16.33 mm
.
We can finally solve for the length s of arc:
     s = r theta = 16.33 * 0.5583  = 9.12 mm

Solve the equation: <img src="https://tex.z-dn.net/?f=5%5Ex%5E%28%5Ex%5E-%5E1%5E%29%3D1" id="TexFormula1" title="5^x^(^x^-^1^)=1
Tomtit [17]

<u>The concept:</u>

We are given the equation:

5^{x(x-1)} = 1

Which can be simplified as:

5^{x^{2} - x} = 1^{1}

Since any number to the power '0' is 1

x² - x must be equal to 0 for the given equation to be true

<u></u>

<u>Solving for x:</u>

x² - x = 0

x(x-1) = 0

now, we can divide both sides by either x OR x-1

So we will see what we get for either choice:

x = 0/(x-1)                           x-1 = 0/x

x = 0                                  x = 1

Hence, the value of x is either 0 or 1
