ide f Pl th th regular hexagon: Pl the unit (cm/inch) cm regular hexagon with sides To make f 5 f 10.0 cm by 8.7 cm. pape is 65.0 tee is 21.7 Th f the hexagon d th 3. (15 pts) Let's make a mini number-guessing game. Write a program that first generates a random integer between 1 and 100, and provide the player with its modulus i e the remainders when divided by 2, 5, or 13. The program then pause until the user is ready to check the answer. An example run is show below. Hint: teach yourself how to use the pause function going to gu integ bet n 1 and 100. Th ind f th integ divided by 2 is 1 is 0 The remainder of the integer divided by 5 ind f the integ divided by 13 i Th y key when you are dy t heck y is 55 Did you gue it right? The number 4. (20 pts Carbon dating is a method that determines the age of fossils based on samples' Carbon 14 radioactivity. Carbon 14, or radiocarbon, is an isotope of the element carbon that is unstable and weakly radioactive. Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes, therefore the level of C14 when they are alive is quite stable. When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay Noe where Nis the remaining radioactivity as a function of time (or age) t, No is the initial radioactivity, k is the rate of decay, and t is time s known that the ha e of C-14 is 5730 years. In other words, it takes 5730 years for its radioactivity to drop to the half of the original level, or N/N 0.5 Write a program that will calculate a sample's age based on its radioactivity. Brief steps 1) Calculate the rate constant k based on the half life of C14 2) Prompt the user for the sample's radioactivity in percentage (N/NoD 3) Calculate sample' age 4) Display the result nicely 5. (25 pts) A homeowner decides to install a round above ground swimming pool. It is du feet in diameter with an hi foot deep water level. There is a recessed portion of the pool where the water level is h2 feet deep. The rece occurs ri feet from the edge and inclines up at a 01 degree angle to the leve ground. A cross-section of the pool is illustrated in the figure below. Solve the following in terms ofthe variables stated. Be sure to follow the problem solving method described in the video labeling each Section. a) How many cubic feet of soil must be excavated from the recessed? b) How many gallons of water will be required to fill the pool? d ft dia hift ri ft Now write a MATLAB script that will prompt the user for the variables d1, hi, h2, r1 in feet, and 01 in degrees, calculate for the questions a) and b), and display proper messages on the screen.
