Steven, Mabel, Sofia, and Finn went on a very long trip to visit their grandfather, Max. They rode a taxi which ran a distance of 40 km within 2 hours after they left the house. During their travel, Mabel received a call from their grand uncle, Ford. His taxi had a flat wheel and asked them to pick him up. They picked him up half an hour later and resumed their way. After an hour, their taxi could not enter the woods where their grandfather lives, so, they decided all together to walk. 50 km, and 10 hours later, they reached Max’s cabin in the woods.
Plot and determine the slope of the curve. (20 points)
Find the distance Steven, Mabel, Sofia, and Finn found Ford during the trip, and the distance where they started to walk.

There is a set of chips of 5 different colours (there are at least 6 chips of every colour). It is necessary to put 6 of these chips in a row (from left to right) in such a way that any two adjacent chips are of different colours, and at least three colours have to be used. How many ways of doing it are there?
There are 18 boys and 35 girls in a mathematical club. For playing some game, the teacher has to distribute chips among the children (their total number is equal to k, and all of them have to be given). It is necessary that all the boys have the same numbers of chips, all the girls have the same numbers of chips, and each of the children has at least one chip. It has turned out that the teacher can distribute the chips in a single way. Determine the largest possible value of k.
The radioactive isotope gallium-67, used in the diagnosis of malignant tumors, has a biological
𝑡
half-life of 46.5 hours. The half-life of the isotope is modeled as 𝐴 = 𝐴0 (1)h , where h is the 2
half-life and t is the time in hours. If we start with 100 milligrams of the isotope, how many milligrams will be left after: 24 hours, and after 1 week?
