Step-by-step explanation:

arctan(x) is less than π/2 for x > 0. Therefore, if we say g(x) = 13 (π/2) / eˣ, then f(x) < g(x) for all values of x > 0.

g(x) = 13 (π/2) / eˣ

g(x) = 13π/2 · (1/e)ˣ

So g(x) is a geometric series where r = 1/e. Since |r| < 1, the series converges.

Since g(x) converges, the smaller f(x) also converges.

Which single transformation can be applied to the graph of y = 72 <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormu

Allisa [31]

Answer:

B. Vertical Compression

Step-by-step explanation:

<em>You've answered the question; However, I'll assist with the explanation;</em>

Given

Original: $y = 72\sqrt x$

Translated: $y = 9\sqrt x$

Required

Determine the type of transformation applied to the original function

Observing both functions, we notice that $\sqrt x$ is a common factor;

This implies that the function was compressed or stretched along the y axis (vertically)

To determine if its vertical compression or stretch;

We have to divide the translated function by the original function;

$Ratio = \frac{9\sqrt x}{72\sqrt x}$

$Ratio = \frac{9}{72}$

$Ratio = 0.125$

<em>Because 0.125 < 1, then the transformation is a vertical compression</em>

Calculate the work done. A tractor pulls a heavy log with a force of 100 pounds. The log moves 3 feet.

Pavel [41]

f = m*a (force equals mass and acceleration)

And since we don't know the actual mass then it's- 100=(m)*3

So when the tractor pulled the log that is, 100 pounds and it only moved 3 feet.

But calculating it (by multiplication) equals to 300 ft-lbs, so therefore it can't be 130 ft-lbs.

So by my guess, it's 300 ft-lbs, since it's impossible and strange to even reach some number as the first and second one.

Your formula for this would be 4/3•3.14•8 cubed then you would round your answer. Hope this helps :)
