- And y+Z=1arrow_forwardPlease solve for problem #3, thank you.arrow_forwardAt the start of the millennium, State A was the third most populous state in the country, followed by State B. Since that time, State B has experienced faster growth. The population y (in millons) of the given state in year x is approximated by the following equations, where x = 0 corresponds to the year 2000, In what year did State B overtake State A in population? To the nearest million, what was the population of these states at that time? State B: 8y - 2x = 160 State A 13y - x = 296 The year State B overtook State A was (Type a whole number.)

- Two children weighing 15 and 22 kilograms are sitting on opposite sides of a seesaw, both 2 meters from the axis of rotation. Where on the seesaw should a 10-kilogram child sit in order to achieve equilibrium?The 10-kilogram child should sit on the same side as the ? kilogram child, ? meter(s) from the axis of rotation.arrow_forwardProblem 13. A truck is 300 miles due east of a car and is traveling west at the constant speed of 30 miles per hour. Meanwhile, the car is going north at the constant speed of 60 miles per hour. At what time will the car and truck be closest to each other?arrow_forwardProvide Solution for the Attached File by using Equation no. 3.24.arrow_forward

Using the variables x, for number of years since 1960, and y, for the size of the population, three models were created to predict the population from the number of years since 1960.arrow_forward
- Solve the following equations: * y" - 3y' + 2y = 2x² + ex + 2xe* + 4e³xarrow_forward4. Find the first three nonzero terms in each of two linearly independent solutions of the equation. (1+x²)y" + xy = 0arrow_forwardTwo tanks are connected as in the figure below. Tank 1 initially contains 20 pounds of salt dissolved in 100 gallons of brine. Tank 2 initially contains 150 gallons of brine in which 90 pounds of salt are dissolved. At time zero, a brine solution containing 1/2 pound of salt per gallon is added to Tank 1 at the rate of 5 gallons per minute. Tank 1 has an output that discharges brine into Tank 2 at the rate of 5 gallons per minute, and Tank 2 also has an output of 5 gallons per minute. a) Determine the amount of salt in EACH tank at any time t.HINT: Solve for the amount of salt in Tank 1 at time t, and use this solution to help determine the amount of salt in Tank 2.b) Find the time when the concentration of salt in the second tank is a minimum and its corresponding concentration.c) Determine the limiting value for the amount of salt in EACH tank after a very long time.arrow_forward
