If the sofa price is $900 more than the price of the chair, then: S=C+900.
If the total for the purchase of sofa and chair is $1200, then S+C=1200.
Use this info to select the correct system of equations. Note: you do not have to solve for S and C.
Answer:
1. C. cylindrical coordinates
2 A. spherical coordinates
3. A. spherical coordinates
4. D. Cartesian coordinates
5 B. polar coordinates
Step-by-step explanation:
USE THE BOUNDARY INTERVALS TO IDENTIFY
1. ∭E dV where E is:
x^2 + y^2 + z^2<= 4, x>= 0, y>= 0, z>= 0 -- This is A CYLINDRICAL COORDINATES SINCE x>= 0, y>= 0, z>= 0
2. ∭E z^2 dV where E is:
-2 <= z <= 2,1 <= x^ 2 + y^2 <= 2 This is A SPHERICAL COORDINATES
3. ∭E z dV where E is:
1 <= x <= 2, 3<= y <= 4,5 <= z <= 6 -- This is A SPHERICAL COORDINATES
4. ∫10∫y^20 1/x dx ---- This is A CARTESIAN COORDINATES
5. ∬D 1/x^2 + y^2 dA where D is: x^2 + y^2 <=4 This is A POLAR COORDINATES
Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7
