sketch the curve with the given polar equation by first
sketching the graph of r as a function of theta in Cartesian
coordinates.
1) r = 3cos(3theta)
2) r = 1 + 3cos(theta)
3) r = sin (theta / 2)
Please solve this problem with a detailed explanation, not just
a answer.

Technology - Excel
Question
The table shows the age in years and the number of hours slept
per day by 24 infants who were less than 1 year old. Use Excel to
find the best fit linear regression equation, where age is the
explanatory variable. Round the slope and intercept to one decimal
place.

Q5. Report the slope and uncertainty in the slope of the linear
fit on your graph, include the correct units. Q6. Use your reported
slope from the graph to calculate the spring constant k, and
include the correct units. Show all work. Q7. Using propagation of
uncertainties, it can be shown that the uncertainty in the spring
constant k may be calculated using Using your graph for the
uncertainty in the slope, along with your answer to Q6, calculate
