Answer:
Step-by-step explanation: The area of the bedroom is
A=7yd^2
The total cost is the sum of the price rates times this area.
C=A•($21+$5)/yd^2
where C is total cost.
C=7yd^2•($21+$5)/yd^2
C=$182
(x²+4x+3)/2(x²-10x+25)
the horizontal asymptote when the numerator and the denominator have the same degree (in this case, both of a degree of 2) is ration of the coefficients of the numerator and denominator. In this case, the coefficient for numerator x² is 1, and the coefficient for the denominator 2x² is 2, so the horizontal asymptote is y=1/2=0.5
the vertical asymptote is the x value. the denominator cannot be zero, if x²-10x+25=0, x would be 5, so the vertical asymptote is x=5
this is just one example. There can be others:
(2x²+5x+2)/[(4x-7)(x-5)] for another example, but this example has a second vertical asymptote 4x-7=0 =>x=7/4
Answer: ![y=\frac{1}{30}x+1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B30%7Dx%2B1)
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where "m" is the slope and "b" is the y-intercept.
You need to find slope of the line with the formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Pick to points of the given line. You can choose the point (60,3) and the point (30,2).
Then, substituting into the formula:
![m=\frac{2-3}{30-60}=\frac{1}{30}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2-3%7D%7B30-60%7D%3D%5Cfrac%7B1%7D%7B30%7D)
You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:
![b=1](https://tex.z-dn.net/?f=b%3D1)
Substituting the slope and the y-intercept found into
, you get the equation of this line:
![y=\frac{1}{30}x+1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B30%7Dx%2B1)
Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.
