Find the value of cos P rounded to the nearest hundredth, if necessary.
Lemur [1.5K]

Answer:

\cos P\approx 0.26

Step-by-step explanation:

In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.

In the given triangle, the adjacent side to angle P is marked as \sqrt{7} and the hypotenuse of the triangle is 10. Therefore, we have:

\cos P=\frac{\sqrt{7}}{10},\\\cos P=0.2645751311,\\\cos P \approx \boxed{0.26}

If point P is 4/7 of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?
Ket [755]

Answer:

4:3

Step-by-step explanation:

Given that P divides segment MN into 4/7, let MN to be x units in length then

MP = 4/7 x =4x/7 --------(i)

But MN =MP+PN so;

x=4x/7 +PN

x- 4X/7 =PN

3x/7 =PN ----------(ii)

To get the ratio of MP:PN

MP: PN

4x/7:3x/7

MP/PN = 4x/7 / 3x/7

MP/PN =4/3

MP:PN = 4:3

Suppose a special discount makes the price of Nike air max shoes 10% lower. As result, there is a 20% increase in the quantity d
Andrew [12]

It is evident from the problem statement that an overall price reduction of Nike air max shoes will lead to an increase in the demand for the shoe.

In Economics,  the relationship between price and demand is stated as follows <em>"If all other factors remain equal, the higher the price of a good, the </em><em>fewer</em><em> people will </em><em>demand</em><em> that </em><em>good</em><em>. In other words, the </em><em>higher</em><em> the price, the </em><em>lower</em><em> the </em><em>quantity</em><em> demanded and vice versa."</em>

<em />

In all, the Law of Demand tells us that if more people want to buy something, given a limited supply, the price of that thing will be bid higher, also of the price of something is low the demand will be high.
