Answer:
$11 and $16
Step-by-step explanation:
let x be the cost of a student ticket then an adult ticket is x + 5 , then
3x + 7(x + 5) = 145 , that is
3x + 7x + 35 = 145
10x + 35 = 145 ( subtract 35 from both sides )
10x = 110 ( divide both sides by 10 )
x = 11
Student ticket costs $11 and adult ticket = x + 5 = 11 + 5 = $16
Solution
Step 1:
Write the total cost function
a) Marginal cost is the first derivative of the total cost
b)
c)
Graph of the marginal cost
The coordinates of the minimum marginal cost is (10 , 7000)
Minumum marginal cost of 7 additional dollars per item produced occurs when 10 thousand items are produced
d)
20 thousands items produced
Range is the y-values of a coordinates. the range for this is 5,4,1,0
Answer:
Missing angle = 135°
Step-by-step explanation:
Given:
Pentagon shape
Number of right angle = 3
Remain two angles are equal
Computation:
Sum of Pentagon angles = 540°
So,
90 + 90 + 90 + a +a = 540
270 + 2a = 540
a = 135°
Missing angle = 135°
