246 SE 0. The equation of a line is given by the function y=mx+b. Determine the value X-intercept (where y=0) of the line defined by the equation y = 3x +9. Using the equation for a straight line, what is the formula for the x intercept 7. What effect will a 1.0°C error (all temperature readings are 1.0°C greater than the actual value) in determining absolute OK? Justify your answer. 8. Whal effect will a 0.10 atm error (reading is...

After creating her standard curve for absorption versus the concentration (M) of FD&C Red 40, a student found that her best fit linear line for FD&C Red 40 was y= 2,896x + -0.004. Her Kool-Aid sample had an absorbance of 0.842. If 0.484 grams of Kool-Aid powder was used to prepare an 8-fl oz cup of her assigned flavor, what is the percent by mass of FD&C Red 40 in her 8-fl oz cup?
Let C1 be the semicircle given by z = 0,y ≥ 0,x2 + y2 = 1 and C2 the semicircle given by y = 0,z ≥ 0,x2 +z2 = 1. Let C be the closed curve formed by C1 and C2. Let F = hy + 2y2,2x + 4xy + 6z2,3x + eyi. a) Draw the curve C. Choose an orientation of C and mark it clearly on the picture. b) Use Stokes’s theorem to compute the line integral ZC...
