D. -√3/2
Step-by-step explanation:
Remember your unit circle.
Alternatively, you can plug in cos(7π/6) into your calc (Put it in rad mode) and calculate your answer.
Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858

Hello!
To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6.
7 to the second power simply means 7x7.
7x7= 49
Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer.
6 x 49 = 294
I hope this helps answer your question! Have a great day!
