Answer:
28
Step-by-step explanation:
Convert 2.5 to minutes = 150 minutes. Then divide 4200/150 which gives you 28 per minute
Answer:
z = 1
Step-by-step explanation:
See the diagram of the triangle attached to this question.
We know the property of angles of a triangle as if we sum any two interior angles then we will get the opposite exterior angle.
Hence,
42z + 37 = 40z + (26z + 13)
⇒ 42z + 37 = 66z + 13
⇒ 37 - 13 = 66z - 42z
⇒ 24 = 24z
⇒ z = 1 (Answer)

<span> if the wavelength of a wave is 2 meters that means that every 2 meters it does its wave thing once. given that it travels 50 meters in one second the wave will have to do its wave thing 25 times in that distance.</span>
Answer:
The correct answer is 10 for lowest average cost and the cost function is 0.2 + 75x + 20.
Step-by-step explanation:
Average cost function is given by = = C(x) = 0.2x + +75.
For minimizing we need to find C(x) = 0.
⇒ C(x) = 0.2 - .
⇒ = 0.2
⇒ = 100.
⇒ x = ±10
⇒ x = 10 ; cost cannot be negative.
Second order derivative is positive which implies the average cost minimizes.
Original cost function is given by C(x) × x = 0.2 + 75x + 20.
