Answer:

d \propto \frac{s}{5}

Step-by-step explanation:

Given : The time between seeing the lightning and hearing the thunder is s seconds.

The distance d you are from lightning is approximately equal to one-fifth of s seconds.

To Find: Which direct variation equation represents this situation?

Solution:

d denotes the distance

s denotes The time between seeing the lightning and hearing the thunder

Since we are given that the distance d you are from lightning is approximately equal to one-fifth of s seconds.

\Rightarrow d \propto \frac{1}{5}\times s

\Rightarrow d \propto \frac{s}{5}

Hence the direct variation equation represents this situation is d \propto \frac{s}{5}

The direct variation that can be established using the given parameters is that, the time it takes between seeing the lightning and hearing the thunder is directly related to the speed. 

However, it can also be established that the time described above is inversely proportional to the distance. This can be written as,
         t = k/d
We substitute the given expression for each of the known terms. t is time, s, and d is distance, 3s. 

    s = k/3s

The k written in the equation is the constant of proportionality.

2) The sum of three consecutive multiples of 6 is 162. Find the multiples.
Andru [333]

Answer:

48, 54 and 60

Step-by-step explanation:

Let the three multiples be 6x, 6(x+1) and 6(x+2) respectively.

6x+6(x+1)+6(x+2)=162

6x+6x+6+6x+12=162

18x=144

x=8

Therefore, the three multiples are 6(8), 6(8+1) and 6(8+2)

i.e. 48, 54 and 60

What is lim x-&gt;-1 sin(pie/6))<br><br><br><br>this is a timed
dlinn [17]

sin(π/6) is independent of x, so

\displaystyle \lim_{x\to-1} \sin\left(\frac\pi6\right) = \sin\left(\frac\pi6\right) = \boxed{\frac12}
