A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
B. What will the value of each card be when they have equal value?
Gift Card 1
Mathematically, lets set T for a time increment of 30 days.
So we can state the value of GC1, in increments of 30 days, as
We want to know the value of T when the cards are equal in value.
So for what value of T does
After 40 30-day periods (1200 days), both cards should have equal value (assuming you don't use them in the meantime). Let's check it:
Card 1 after 40 periods:
According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Give the distribution of X. Enter an exact number as an integer, fraction, or decimal.
Given that a stone is thrown into a pond, creating a circular ripple that spreads over the pond in such a way that the radius is increasing at a rate of 3.4 ft/sec.
Complete parts a through c.
a) Find a function for the radius in terms of t.
(Use integers or decimals for any numbers in the expression.)
