46. According to an online article in the New Scientist
(Catherine Brahic, “Carbon Emissions Rising
Faster Than Ever," p. 9), recent research suggests
that stabilizing carbon dioxide concentrations in
the atmosphere at 450 parts per million (ppm)
could limit global warming to 2°C. In Section 1.2,
V(x) = 0.005e
0.24x + 0.495e¬0.12x cm3
cm
where x is measured in days after the drug was
administered. Using Newton's method, solve
within a tolerance of 0.01 for the time x at which the
tumor volume has doubled in volume. For an initial
we modeled carbon dioxide concentrations in the
guess, use x = 25 days.
42. In Example 4 of Section 4.3, we considered the
growth of a tumor in a mouse after the mouse was
given a drug treatment. To model the volume of the
tumor, we used the function
atmosphere with the following function (which
we now present to higher precision to make more
transparent the numerical details of the conver-
gence process):

where x is months after April 1974. In Example 11
of Section 2.3, we used the bisection method to es-
timate the first time that the model predicts carbon
dioxide levels of 450 ppm. Use Newton's method
to estimate this time with a stopping value of
E = 0.001.
where x is measured in days after the drug was
administered. Using Newton's method, solve within
a tolerance of 0.01 for the time x at which the tumor
volume has quadrupled in volume. For an initial
guess, use x = 30 days.
43. In Problem 25 in Problem Set 4.3, you found that the
volume of a tumor for mice under a different drug

until reaching 400 ppm.
