Answer:
b = -0.0012a +211
208.36 °F at 2200 ft
Step-by-step explanation:
We are given two points:
(a, b) = (8100, 201.28) and (4300, 205.84)
The slope of the desired line can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (205.84 -201.28)/(4300 -8100) = 4.56/-3800 = -0.0012
The "y-intercept" of the function can be found from ...
y-intercept = b -ma
y-intercept = 201.28 -(-0.0012)(8100) = 211.00
So, the function of interest is ...
b = -0.0012a +211
__
At 2200 ft, the boiling point is ...
b = -0.0012×2200 +211 = -2.64 +211 = 208.36
The boiling point of the liquid at 2200 ft is 208.36 °F.
here it is, hope i helped :)

Answer:
((2 x^2 + 1)^2)/(x^2)
Step-by-step explanation:
Simplify the following:
(2 x + 1/x)^2
Hint: | Put the fractions in 2 x + 1/x over a common denominator.
Put each term in 2 x + 1/x over the common denominator x: 2 x + 1/x = (2 x^2)/x + 1/x:
((2 x^2)/x + 1/x)^2
Hint: | Combine (2 x^2)/x + 1/x into a single fraction.
(2 x^2)/x + 1/x = (2 x^2 + 1)/x:
((2 x^2 + 1)/x)^2
Hint: | Distribute exponents over quotients in ((2 x^2 + 1)/x)^2.
Multiply each exponent in (2 x^2 + 1)/x by 2:
Answer: ((2 x^2 + 1)^2)/(x^2)
