The average change in the field position on each run is. -1 3/4
Answer:
(4,1)
Step-by-step explanation:
The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).
To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.
To find the y-coordinate, input the x=4 and solve for y.
The vertex is (4,1).
Answer:
x=1/2
Step-by-step explanation:
10-2x=14x+2
8/16=16x/16
x=1/2
Answer:
47.84%
Step-by-step explanation:
The easiest method to solve this exercise is to assume that the starting diesel price is 100 reais.
Now we will calculate each increase with our assumption:
1. Initial price plus 10% increase, therefore:
100 + 100 * 0.1 = 110 reais
2. Additional 20% increase in relation to 110 reais:
110 + 110 * 0.2 = 132 reais
3. Additional 12% increase in relation to 132 reais:
132 + 132 * 0.12 = 147.84 reais.
What it means is that the price would be 147.84 reais.
Since our assumption is 100, we can know that there was an increase of almost 47.84% in relation to the initial price that we assumed at the beginning.
Attached the solution and work.
