Answer:
66600 ft
Step-by-step explanation:
First draw a rectangle and draw a diagonal line in the middle. The line makes two triangles, and the line itself is the hypotenuse. So, to find hypotenuse, the formula is:
a^2 + b^2 = c^2
The variable c defines the hypotenuse. Therefore:
a = 150
b = 210
Let's solve:
150^2 + 210^2 = c^2
22500 + 44100 = c^2
66600 = c^2
Therefore, in conclusion, the result we are getting is 66600 ft.

f(-4) = 3(-4)^2 - 2(-4)
f(-4) = 3(16) + 8
f(-4) = 48 + 8
f(-4) = 56
I think the answer is 56 :)

Answer:
A) quantitative
Step-by-step explanation:
A data that can be counted or expressed numerically constitute quantitative data. Quantitative data collection method is capturing statistical data in numbers, figures, or values. Quantitative data collection usually answered the questions of “how many?”, "how much?" and “how often?” are the occurrence of a particular data. These questions are quantitative data collection methods based on numbers and mathematical calculations. Quantitative data collection methods are based on random sampling and structured data collection. Some of the quantitative data collection methods are surveys, questionnaires, quizzes, interviews and direct observation.
Use this equation y = a (1 - b)^x
Where a is the initial population and b is the decay factor: 40/100 = 0.4
Therefore, the answer is that the decay factor b is 0.4.
This table shows some figures using the decay factor.
year decrease population
0 0 a(1 - 0.4)^0 = a
1 a*0.4 a (1 - 0.4)^1 = a*0.6 = 0.6a
2 0.6a*0.4 a(1 - 0.4)^2 = a(0.6)^2 = 0.36a
3 0.36a*0.4 a(1 -0.4)^3= a(0.6)^3 = 0.216a
