The possible disadvantage of using the graphic in “On-line Programs to Train Your Brain is: Because the graphic looks “child-like” readers may not take the author seriously.

<h3>What is the disadvantage of online programs?</h3>

Now, online programs used in training our brain doesn't take anything seriously because for example, during online classes, a lot of students are not as serious as they would have been physically which makes them to loose their marks and that's all caused by our brain cause we think we can learn it later and we don't but instead just ignore it.

Thus, the possible disadvantage will be that the graphic looks “child-like” readers may not take the author seriously.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. the angle

Mekhanik [1.2K]

The height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

<h3>What is right angle triangle property?</h3>

In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.

$\tan\theta=\dfrac{b}{a}$

Here, (b) is the opposite side, (a) is the base side.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence.

The angle of elevation of the tree from one position on a flat path from the tree is

$H=40^o$

From a second position,

$I=60\rm\; ft$

Farther along this path it is,

$b=30^o$

Let the distance between tree and first position is x. Thus, from the trigonometry,

$\tan 40=\dfrac{h}{x}\\h=x\tan 40$ ....1

The distance between tree and second position is (x+60) ft. Thus, again from the trigonometry,

$\tan 30=\dfrac{h}{x+60}\\h=(x+60)\tan 40$ ......2

Compare the equation 1 and 2,

$x\tan (40)=(x+60)\tan 30\\0.839x=0.577x+34.64\\0.839x-0.577x=34.64\\x=\dfrac{34.64}{0.262}\\x=132.25\rm\; ft$

Put this value in equation 1 as,

$h=(132.25)\times \tan40\\h\approx111\rm\;ft$

Thus, the height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

All of the following are effective countermeasures of fatigue except: D. Allowing your eyes to lose focus.

<h3>What is a countermeasure?</h3>

This is the term that helps to describe something that helps a person to fight against another thing. The counter measure is usually what is taken in order to prevent something from happening or occurring.

Here fatigue has to do with the fact that a person is tired, worn out and they need to rest well in order to continue functioning properly in the chores or the tasks that they are known to indulge in.

When a person is tired they would have issues with their eyes enabling them to focus on what they are doing.

The answers are hyper cortisol response and higher levels of physical aggression.

<h3>What is hyper cortisol?</h3>

When the body is exposed to excessive quantities of the hormone cortisol for an extended period of time, hypercortisolism, also known as Cushing syndrome, develops.

Mike lives in the northern united states (in minnesota) and nick lives in the southern united states (louisiana). when they both feel insulted by the same individual, nick will be more likely to have a(n) hyper cortisol response and show higher levels of physical aggression.

Cortisol is a stress-inducing hormone, according to research on hormones in the human body. Now, it has been proved that when it is hot in the summer, the cortisol hormone circulates in the blood in a very significant amount. This can result in frustration as well as physical hostility.

Thus, the answers are hyper cortisol response and higher levels of physical aggression.
