2. The integration region,
corresponds to what you might call an "annular sector" (i.e. the analog of circular sector for the annulus or ring). In other words, it's the region between the two circles of radii and , taken between the rays and . (The previous question of yours that I just posted an answer to has a similar region with slightly different parameters.)
You can separate the variables to compute the integral:
which should be doable for you. You would find it has a value of 19/72*(3√3 + 4π).
3. Without knowing the definition of the region <em>D</em>, the best we can do is convert what we can to polar coordinates. Namely,
so that
Answer:
B)
Step-by-step explanation:
The question states that Dai has 4 more cards than twice the number of cards Maura has.
"more" - add
"twice" - multiply by 2
Let n be equal to the number of cards that Maura has.
Let D be equal to the number of cards that Dai has.
When we translate this into an <em>equation</em>, we would get something that looks like...
Since Dai has four more cards than twice the number of cards Maura has, 2 times the number of cards Maura has plus four is equal to the number of cards Dai has. Hopefully this is easier to understand written like an equation!
Therefore, the expression would be .
I hope this helps!

Answer:
12
Step-by-step explanation:
so $8.06 / .65 = 12.4 but you cannot buy .4 of a bagel so the answer would just be 12
