Answer:
The equation is either n-6^3 (this is without cubing the 6, this is probably what your teacher is looking for.) or n-216 (this is what the equation looks like when 6 is cubed)
The exact value of sin θ and cos θ is: sinθ =(√105)/19 and cosθ =16/19
The terminal side of an angle is the angle at the standard position. The terminal side of an angle θ drawn in angle standard position is the side which isn't the initial side.
Given that the point of intersection of the terminal side of θ an the unit circle is:
(16/19,y)
The exact value of sin θ and cos θ is: sinθ =(√105)/19 and cosθ =16/19
The given parameters is represented by:
(16/19,y)
This means that :
(cosθ ,sinθ )=(16/19,y)
Using the following trigonometric identity:
cos²θ +sinθ =1
We have:
(16/19)²+y²=1
Expand fraction:
(256/361)+y²=1
Collect like terms:
y²=1-(256/361)
Take LCM:
y²=(361-256)/361
y²=105/361
Take square roots
y=(√105)/19
Substitute value for y in
(cosθ ,sinθ )=(16/19,y)
By comparison:
cosθ =16/19
sinθ =(√105)/19
So the exact value of sin θ and cos θ is: sinθ =(√105)/19 and cosθ =16/19

The uncertainty in x is the horizontal width of the rectangular marker, which is 0.05 mm.
The uncertainty in y is the height of the rectangular marker, which is 0.1 g.
Answer:
8x + 3x (x - 4)² x - 4
Step-by-step explanation:
Use Product rule: xᵃ xᵇ = x ᵃ⁺ᵇ
8x + 3 (x - 4)² x - 4
Regroup Terms
8x + 3x (x - 4)² x - 4
Answer:
When the produced item greater than 2, the average cost will be less than 100
Step-by-step explanation:
C(x) / x = 100 ... when x items produced and the cost is 100
(20x + 160) / x = 100
20x + 160 = 100x
80x = 160
x=2
