60 miles an hr.. Because 180 divides by three is 60 and that is the answer per hr
Answer:
The solution of given system is
Step-by-step explanation:
<u>Explanation</u>:-
Given 12t−2<−5t+36
<u>Step(i)</u>:-
Adding '5t' on both sides, we get
12t - 2 +5t < -5t +36 +5t
17t -2 < 36
<u>Step(ii)</u>:-
Adding ' 2' on both sides , we get
17t -2 +2 < 36 + 2
17t < 38
<u>Step(iii)</u>:-
Dividing '17' on both sides , we get
<u>Conclusion</u>:-
The solution of given system is
Answer:
3

Denote the circle of radius by . is simple and closed, so by Green's theorem the line integral reduces to a double integral over the interior of (call it ):
is a circle of radius , so we can write the double integral in polar coordinates as
a. For , we have
b. Let denote the integral with unknown parameter ,
By the fundamental theorem of calculus,
has critical points when
If , then line integral is 0, so we ignore that critical point. For the other two, we would find .
