Answer:
A. 520 square inches is your surface area of the rectangular prism
Answer:
The measure of angle IJU is 20 degrees.
Step-by-step explanation:
In order to find that, we need to add the two angles together and set equal to 180 degrees. Then we can solve for x.
(3x - 7) + (17x + 7) = 180 ----> Combine like terms
20x = 180 -----> Divide by 20
x = 9
Now that we have this, we can stick the value into the equation and solve for IJU.
IJU = 3x - 7
IJU = 3(9) - 7
IJU = 27 - 7
IJU = 20
Answer:
The rectangular coordinates of the point are (3/2 , √3/2)
Step-by-step explanation:
* Lets study how to change from polar form to rectangular coordinates
- To convert from polar form (r , Ф) to rectangular coordinates (x , y)
use these rules
# x = r cos Ф
# y = r sin Ф
* Now lets solve the problem
∵ The point in the rectangular coordinates is (√3 , π/6)
∴ r = √3 and Ф = π/6
- Lets find the x-coordinates
∵ x = r cos Ф
∵ r = √3
∵ Ф = π/6
∴ x = √3 cos π/6
∵ cos π/6 = √3/2
∴ x = √3 (√3/2) = 3/2
* The x-coordinate of the point is 3/2
- Lets find the y-coordinates
∵ y = r sin Ф
∵ r = √3
∵ Ф = π/6
∴ y = √3 sin π/6
∵ sin π/6 = 1/2
∴ y = √3 (1/2) = √3/2
* The y-coordinate of the point is √3/2
∴ The rectangular coordinates of the point are (3/2 , √3/2)
the opposite or addictive increase of 5x is -5x.
the opposite or addictive increase of 5x + 8 is -5x -8.
