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:
x = -1
Step-by-step explanation:
3^x = 1/3
3^x= 3^-1
x=-1
It’s about 13.925. I rounded up
The tangent ratio is
tan(38°) = opposite/adjacent = (height of cliff)/(distance to base)
Multiplying the equation by the denominator gives
height of cliff = (80 ft)*tan(38°) ≈ 62.5 ft
All interior angles equal to 180 just add the two angles you have and subtract it from 180 to get the final angle
