What is an equation in point-slope form for the line that passes through the points (4,-1) and (-3, 4)? y – 4 = -5/7(x + 3)
y+ 4 = -5/7(x + 3)
y+4 = 5/7(x + 3)
y – 3 = -5/7(x + 4)

Shiny white dental insurance costs $258 per year. approximately one-third of insured people need a filling, which averages $110 each. 80% of insured people get a preventive check-up each year, and the average cost of this visit is $95. if you consider shiny white’s income and expenses, what is the expected value of each insured customer?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
