Conversion Formula: Radian/π = Degree°/180°
R= 7π/4, Degree =?
Apply the formula:
So [(7π/4) / π = Degree / 180] (note that 7π/4) / π = 7/4)
Degree = (7/4) x 180° = 315°
Answer:
The answer to your question is 3, 9, 19, 33, 51
Step-by-step explanation:
Sequence an = 2n² + 1
1st term a₁ = 2(1)² + 1 = 2(1) + 1 = 2 + 1 = 3
2nd term a₂ = 2(2)² + 1 = 2(2)² + 1 = 2(4) + 1 = 8 + 1 = 9
3rd term a₃ = 2(3)² + 1 = 2(3)² + 1 = 2(9) + 1 = 18 + 1 = 19
4rd term a₄ = 2(4)² + 1 = 2(4)² + 1 = 2(16) + 1 = 32 + 1 = 33
5th term a₅ = 2(5)² + 1 = 2(5)² + 1 = 2(25) + 1 = 50 + 1 = 51

The revenue when the number of units is 18 is -135
<h3>How to determine the revenue?</h3>
The given parameters are:
Revenue function
R(x) = x *P(x)
Where
P(x) = 42/(4) − x
Substitute P(x) = 42/(4) − x in the equation R(x) = x *P(x)
R(x) = x * [42/(4) − x]
The number of units sold is 18.
So, we have:
R(18) = 18 * [42/(4) − 18]
Evaluate the expression
R(18) = -135
Hence, the revenue when the number of units is 18 is -135
