Creative use of formatting may make this problem clearer to me, to other helpers and perhaps to you as well. As typed, your

31y^3

Sqrt31y^3/9x^6 seems to indicate Sqrt( ----------- )

x^6

31y³

or √( ---------- )

x^6

√31 cannot be reduced.

√(y³) = y√y.

√(x^6) = x³

Putting this all together, we get the final answer

√31*y*√³

( --------------- )

x³

I believe it would be dilated by 3/4

If you think of a rectangle, let’s say it is 8 by 4, the perimeter of this rectangle would be 24.

Now if you dilate the side values, you get 6 by 3 and the perimeter equals 18

So you then get 18/24 which is equal to 3/4

Hope this is right and makes sense! Have a good day!

A colony of bacteria triples in link every 10 minutes. It's length is now 1 mm. How long will be in 40 minutes

Nuetrik [128]

If the bacteria is tripling every 10 minutes, that means the "rate of increase" on that period is 200%, so if say the current amount is "c", 200% of "c" is just 2c, so c + 2c is 3c, a tripled amount.

$\bf \textit{Periodic Exponential Growth}\\\\
A=I(1 + r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &1\\
r=rate\to 2\%\to \frac{200}{100}\to &2.00\\
t=\textit{elapsed time}\to &40\\
p=period\to &10
\end{cases}
\\\\\\
A=1(1 + 2)^{\frac{40}{10}}$

The wind speed near the center of a tornado is represented by the equation S=93logd+65, where d is the distance, in miles, that

dezoksy [38]

Answer:

Therefore,

Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.

Step-by-step explanation:

Given:

The wind speed near the center of a tornado is represented by the equation,

$S=93\log d+65$

Where,

d = the distance, in miles

S = the wind speed, in miles per hour.

To Find:

S = ? at d = 4 miles

Solution:

We have

$S=93\log d+65$ .........Given

Substitute d = 4 in above equation we get,

$S=93\log 4 + 65=93\times 0.602 +65=120.99$

Rounding the answer to the nearest tenth we have

$S=121.0\ mph$

Therefore,

Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
