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.
Answer:
Step-by-step explanation:
You would do 25x5 and it is 125 so now you would subtract 300 from 125 and it would be 275
Is it number15?
then it is
3x = 180
x = 60
x will be 60
-6x^4y^5-15x^3y^2+9x^2y^3
The GCF OF -6, -15, & 9, is -3
The GCF OF x's is x^2
The GCF OF y's is y^2
These are the number of x's and y's that each term has.
-3x^2y^2(2x^2y^3+5x-3y)
