The third one I think btw if you get mad at this person
<span>The answer is 2 person. The relation for 2 persons is as following: 2 minutes = 2 gingerbread men. If those 2 persons want to make 400 gingerbread men, they will need x minutes. So: 2 minutes : 2 gingerbread men = x : 400 gingerbread men. x = 2 minutes * 400 gingerbread men : 2 gingerbread men = 400 minutes. In other words, 2 persons will make 400 gingerbread men in 400 minutes.</span>
Option b is true to match the vector field f with the given plot f(x, y)=x, -y
<h3>What is meant by a function?</h3>
The earliest known attempts at the concept of functions can be traced back to the work of the Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. Originally, functions were idealized dependencies of one variable on another. For example, planetary positions are functions of time. Historically, this concept was developed in calculus towards the end of his 17th century, and the functions studied were differentiable (i.e. they had a high degree of regularity) until his 19th century ).
Given,
f(x, y) = x, -y
gt; at x⇒∞, y⇒-∞ downwards
at x⇒∞, y⇒+∞ downwards
Therefore, option b is true to match the vector field f with the given plot
f(x, y)=x, -y

The complete question is as follows:
Match the vector field f with the correct plot. f(x, y) = x, −y
Answer:
dude this was last year stuff
Step-by-step explanation:
128°
Because triangle QRS is isosceles, angles QSR and SQR are congruent. The three angles in a triangle must total 180°, and since mQRS is 38°, the sum of mQSR and mSQR must be 142°. Since they are congruent, both angles are 71°.
In triangle PQS, mQPS is 33° and mPSQ is 90°, meaning mSQP is 57°. (90+33=123; 180-123=57)
mPQR can be found by adding mPQS (57°) and mSQR (71°).
Therefore, mPQR=128°.
