Step-by-step explanation:
-9-(-6)+(-4)
-9+6-4
-3-4
-7
Answer:
7 units
Step-by-step explanation:
Given
Required
The units that minimize the average cost
Differentiate
Equate to 0 to solve for x
Collect like terms
Divide by 98
Rewrite as:
Take square roots of both sides
Take multiplicative inverse of both sides
Only positive value will produce critical value. Hence, 7 units will produce the minimum average cost
Answer: sqrt(61)
Step-by-step explanation:
For parts a) and c1), refer to the attached picture.
For part b), the distance formula is:
d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
Using x1 = -1, y1 = -4, x2 = -6, y2 = 2:
d = sqrt[(-6 + 1)^2 + (2 + 4)^2] = sqrt[25 + 36] = sqrt(61)
Part c2) Another way to find the length of AB without using the distance formula is by drawing the line and measuring it according to the scale.
Part d) This will only work as long as the graph paper is accurately made, and the scale computation is done correctly. However, this will only give approximations, and will not give an exact answer when radicals are involved.
