Answer: 16,940 from interest.
Explanation: The cost of it is 28,000 and when you figure out what 5.5% of that is it will come to be 1,540. Next you multiply 1,540 by the 11 years so it would come to 16,940.
Solve for the area of the circular region first:
A = pi*r^2
A = pi*(30 mi)^2
A = 2827.43 mi^2
Density = 70000 people/2827.43 mi^2
Density = 24.76 = 25 people/mi^2 <--ANSWER Plz vote brainnliest
Answer:
Option B)
is the correct option.
Step-by-step explanation:
<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>
Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.
Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.
Or we can use the cost function,
, to find which function has the least error.
By applying the above results,we find Option B is correct.
Answer:
Step-by-step explanation:
This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):
![sin^{-1}[sin(2x+30)]=sin^{-1}(1)](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%5Bsin%282x%2B30%29%5D%3Dsin%5E%7B-1%7D%281%29)
On the left, the inverse sin "undoes" or cancels the sin, leaving us with
2x + 30 = sin⁻¹(1)
The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:
2x + 30 = 90 and
2x = 60 so
x = 30
You're welcome!
