Use technology to find the line of best fit for the following data. (1, 5), (2, 3), (3,3), (4,4), (5,3)

When the equation of the line is in the form y=mx+b, what is the value of **b**?

Enter your answer as a decimal rounded to the nearest tenths place, like this: 42.5

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Find a parametrization for the curve「and determine the work done on a particle moving along γ in r3 through the force field f: r^3--r^3'where f(x,y,z) = (1,-x,z) and (a) im (γ) is the line segment from (0,0,0) to (1,2,1) (b) im (γ) is the polygonal curve with successive vertices (1,0,0), (0,1,1), and (2,2,2) (c) im (γ) is the unit circle in the plane z = 1 with center (0,0,1) beginning and ending at (1,0,1), and starting towards (0,1,1)
