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
Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:

Let’s solve for <em>x: </em>
Combine LIke Terms:

Add:

Subtract 80 from both sides:

Divide both sides by 25:

Therefore, the value of <em>x </em>is 4.
Now, to find A, we can substitute it for A.
A is measured by:

Substitute 4 for <em>x</em> and evaluate:

Hence, our answer is D.
Answer:
B. y+ 4 = 3/4 (x-6)
Step-by-step explanation:
Given:
m = 3/4
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = 3/4(x - 6)
Answer:
-0.95
Step-by-step explanation:
Divide the percent by 100 and since you are decreasing it would be a negative.

you'll get a decimal format, just multiply it times 100, to get the % format
