Answer:

Step-by-step explanation:

On the attachment, there is the graph for the region "R" and the calculations for the value a and b.
the theory is that you have to choose a value that is between the range and assume that this value will divide the area into two equal parts. This is done for x = a
For
"y" you have to change the integral from dx to dy and you have to divide the region into 2 parts, given that the area cannot be calculated by 1 integral equation, so you proceed to calculate the rectangular area and take this area into consideration, for the same procedure as before.
Then you calculate again the value y = b and that's it.
Okay so your equation is going to be : 18= 5k + 3.25p
Answer:
57 kilometers a day.
Step-by-step explanation:
I just divided 513 by 9 and got that.
i think the answer is 8
bc the small one is 4 and the big one is 6
and the other one is 6 so it must be 8
