Answer:
- Time = approximately mid 2012
- Oil import rate = 3600 barrels
Step-by-step explanation:
<h3><em>Unclear part of the question</em></h3>
- I(t) = −35t² + 800t − 1,000 thousand barrels per day (9 ≤ t ≤ 13)
- According to the model, approximately when were oil imports to the country greatest? t = ?
<h3>Solution</h3>
Given the quadratic function
- <em>The vertex of a quadratic function is found by a formula: x = -b/2a</em>
<u>As per given function:</u>
<u>Then</u>
- t = - 800/2*(-35) = 11.43 which is within given range of 9 ≤ t ≤ 13
This time is approximately mid 2012.
<u>Considering this in the function, to get oil import rate for the same time:</u>
- l(11.43) = -35*(11.43)² + 800*11.43 - 1000 = 3571.4285
<u>Rounded to two significant figures, the greatest oil import rate was</u>:
Answer:
Step-by-step explanation:
<u>As per the graph the order of transformations is:</u>
1. 90 degree anticlockwise rotation about origin
2. Reflection across x-axis
- This map A'B'C' to A''B''C''
Correct option is B (transformations read and applied from right to left)

Answer:
0.68L per dispenser
Step-by-step explanation:
Big bottle contain 213L of soap.
Big bottle will fill 312 dispensers.
This means 1 each dispenser can take 213/312 litres = 0.68L per dispenser.
