Answer:
1. false
2. false
3. true
Step-by-step explanation:
1. If the value of a was negative, then the graph of the quadratic would open downwards because the negative sign would induce a reflection of the graph over the x-axis.
However, we can see from the graph that the quadratic opens up, so a is not negative and this statement is false.
2. The vertex of a quadratic equation is the minimum or maximum point. Here, since the graph points up, the vertex will be the minimum point. That point is actually (3, -1). Clearly, this is not (-1, 3), so the statement is false.
3. The axis of symmetry is essentially the line with the x-value of the vertex. Since the x-coordinate of the vertex is 3, that means the axis of symmetry is the line x = 3. Thus, the statement is true.

Answer:
C
Step-by-step explanation:
In sentence C, all the verbs are in the same tense- past tense.
bought and prepared
C - fixed costs; b - costs per bicycle;
c + 110 b = 10,900
c + 130 b = 11,600
c = 10,900 - 110 b
10,900 - 110 b + 130 b = 11,600
20 b = 700
b = 700 : 20 = $35
c + 110 * 35 = 10,900
c + 3,850 = 10,900
c = 10,900 - 3,850
c = $7,050 ( daily fixed costs )
Marginal cost is the cost of producing one more unit of goods ( one more bicycle ).
Answer:
The company`s daily fixed cost is $7,050.
The marginal cost per bicycle is $35.
