To find the area of his exclusion zone you would need to understand that a triangle with dimensions of 3, 4, and 5 represent a right triangle.
This means the exclusion zone would be applied to the base and the height of the triangular space.
You would add 2 km to the 3 km, and 2 km to the 4 km to create a new height of 5 km and a new base of 6 km.
Please see the attached picture to understand this.
You will find the area of the total space created by the new triangle and subtract the space represented by the original triangle to find the area of the exclusion zone.
(1/2 x 6 x 5) - (1/2 x 4 x 3)
15 km² -6 km² equals 9 km².
The exclusion space is 9 km².
B would be the correct answer, I believe.
ratio for the first mix is 3:2 the ratio for the second mix is 4.5:3
Yes, since 3 times 1.5 is 4 and 2 times 1.5 is 3
What are

supposed to be? Can't answer a/b without that information.
I'll come back to part (c) in a moment. If we can show
is conservative, this part will be a breeze.
For part (d), to show whether
is conservative, we have to show that there is a scalar function
such that
. It appears that you've written
I'm not sure what to make of the

means that
Integrating the first PDE with respect to

Differentiating with respect to
gives
But we assumed that

alone, which means there is no solution for

. Hence
is not conservative.
Back to part (c).
is not conservative, so we have to compute the line integral the "long" way. Replacing
and
, we have
Answer:
<u>The next year population is 122,689</u>
Step-by-step explanation:
<u>The computation of the next year population is as follows:</u>
<u>= This year population × increase percentage</u>
<u>= 119,000 × (1 + 0.031)</u>
<u>= 119,000 × 1.031</u>
<u>= 122,689</u>
<u>Hence, the next year population is 122,689</u>
<u>The above formula is applied so that the correct value of the population could come</u>
<u>and the same is relevant</u>
