Answer: The answer is (A) [0,100].
Step-by-step explanation: Given in the question that a marine biologist Kelsey determined that the population of Blue Whales off the coast of Antarctica varies with time as shown in the given graph.
The population of Blue Whales (y) is plotted on the Y-axis and the time in months (x) is plotted on the X-axis.
We need to find the range of the population of Blue Whales off the coast of Antarctica from 0 to 10 months.
We can see from the attached graph that
when x = 0, then y = 0,
when x = 10, then y = 100.
That is, when time varies between 0 to 10 months, then the population of Blue Whales varies between 0 and 100.
Thus, the correct option is (A) [0,100].
Answer:
1
The common factors of 8 and 9 are 1, intersecting the two sets above. In the intersection factors of 8 ∩ factors of 9 the greatest element is 1. Therefore, the greatest common factor of 8 and 9 is 1.
Answer:
The answer to question 5 is x = 23. The answer to question 6 is x = 17.
Step-by-step explanation:
Two Key Points:
- Angles on a straight line always add up to 180°
- The angles in the inside of a triangle add up to 180°
I have attached a picture showing how to do the two problems. I hope this helps!
//To have the lines parallel, the gradients must be the same.
y -- 6 = 1/2 (x - 9)
y + 6 = 1/2 x -9/2
y = 1/2 x - 10.5
We know that
2l + 2w = 24
And:
l = 3w
By substitution:
2(3w) +2w = 24
6w + 2w = 24
8w = 24
w = 3 metres
l = 3 x 3 = 9 metres
Total cost = 24 x $25 = $600
