Option C: is the predicted population when
Explanation:
The regression equation for an exponential data is
Where x is the number of years and
y is the population
We need to determine the predicted population when
The population x can be determined by substituting in the equation
Thus, we have,
Using the logarithmic definition then
Rounding off to the nearest whole number, we get,
Thus, the predicted population when is 316
Hence, Option C is the correct answer.
9514 1404 393
Answer:
a) <8.356, 9.959>
b) <-0.605, -1.663>
c) <-5.023, 2.9>
Step-by-step explanation:
Many calculators can perform polar ⇔ rectangular conversion. Attached is the result from one of them. Of course, you can also program a spreadsheet to do it. (The ATAN2( ) function is useful for finding the correct angle.)
If you want to do these calculations by hand, the conversion is ...
<r, θ> ⇒ <r·cos(θ), r·sin(θ)>
In the attached, the rectangular coordinates are shown as complex numbers. The imaginary component is the y-component of the vector.
