Let a be the vector of length 125 that when drawn in standard position makes a 144° angle with the positive x-axis. Let b be the
umka2103 [35]

Answer:

The length is 90.033 and the angle that v makes with the positive x-axis is 153.339°

Step-by-step explanation:

Firstly we will have to convert our given vectors to their rectangular Cartesian vector form as follow,

a=125(icos(144)+jsin(144))=-101.127i+73.473j\\b=39(icos(302)+jsin(302))=20.667i-33.074j

Now that we have these, we can add them to obtain v as follows,

v=a+b\\v=-80.46i+40.399j

Now that we have the Cartesian vector form we can calculate its length and its direction with respect to the positive x-axis as follows(In fact we usually refer the angles from the positive x-axis),

|v|=\sqrt{80.46^{2}+40.399^{2}}=90.033\\ angle(v)=tan^{-1}(40.399/(-80.46))=153.339

So the length of the vector is 90.033 and the angle it makes with the positive x-axis is 153.339°.

Which property is shown? (mn)5 = m5n5
sineoko [7]
In this item, we are asked to identify which among the given choices is a property that is being shown by the equation,
 
                         (mn)⁵ = m⁵n⁵

It can be observed that m and n are multiplied to each other, inside the parentheses for the expression written on the left side of the equation. Also in the right hand side of the equation, 5 which is the power, is distributed to the elements m and n. 

The property that is being depicted in this number is the power of a product property. Thus, the answer to this item is letter B.
