This depends on the inequality sign is compared to the y variable

For example, if the inequality is y < x, you would shade under the line x

If the inequality is y > x, you would shade above the line x.

The pair of numbers whose difference is 18 and whose product is as small as possible is? The minimum product is?
earnstyle [38]
Assume the bigger number is x, since the difference is 18, another one should be x - 18

So the product will be x(x-18) = x^2 - 18x = (x-9)^2 - 81

Since the minimum of (x-9)^2 is 0, then the minimum of the product is -81

If a wave has a wavelength of 0.5 m and a frequency of 2134 Hz, what is its speed? *SHOW ALL 4 STEPS.
nexus9112 [7]
<h3><u>given</u>:</h3>

wave length= 0.5 m

frequency= 2134 Hz

<h3><u>to find</u>:</h3>

the speed

<h3><u>solution</u>:</h3>

v = f \gamma

v = velocity

f = frequency

\gamma  = wave \: length

v = 2134 \times 0.5

v = 1067s

<u>hence</u><u>,</u><u> </u><u>the</u><u> </u><u>speed</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>wave</u><u> </u><u>is</u><u> </u><u>1067s</u><u>.</u>
