It sounds like <em>R</em> is the region (in polar coordinates)
<em>R</em> = {(<em>r</em>, <em>θ</em>) : 2 ≤ <em>r</em> ≤ 3 and 0 ≤ <em>θ</em> ≤ <em>π</em>/2}
Then the integral is

9514 1404 393
Answer:
D) No Solutions
Step-by-step explanation:
The lines have the same slope (-4), but different y-intercepts (3, 0), so they are parallel lines. There can be no values of x and y that satisfy both equations.
There are no solutions.
Answer:
4 x 13
Step-by-step explanation:
GCD of 28 and 24 is 4
28 = 4 x 7
24 = 4 x 6
u take the 4 out
4 (7 + 6)
4 x 13
Answer:
A. 270
Step-by-step explanation:
30% can be rewritten as 3/10
To multiply 900 by 3/10, just divide by 10 (90) and multiply by 3 (270)
Therefore, the answer is A. 270
Bonus: To find the actual price, just subtract this amount (270) from the original price (900).
The television costs $630.
