wait. in fact, already they have Byju's tab for their grade and they do get study materials video/notes from school on daily bases, which has to be followed up on daily bases by appointed tutor as a part time job in evening, furthermore study material already provided by school and Byju's to be referred, in order to clear the concept of child, especially for maths, then Science, English, Social Studies, Hindi and all. Interested one to contact with CV for further discussion on email Id- ssiddiquie4@gmail.com

b the link is https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html and these are the questions 2: Raise the cannon to a height of 15 meters. Set the horizontal velocity to 12 m/sa) Sketch the situationb) Predict the distance you have to place the target from the base of the cannon (calculate this & show all work). c)Perform the experiment by placing the target at the predicted range and clicking the cannon button. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?) 3: Raise the cannon to a height of 5 meters. Measure the distance of the David statue from the base of the cannona) Sketch the situation.b) Predict the velocity with which you have to launch the object in order for it to hit the statue (calculate this & show all work).c)Perform the experiment by entering the predicted velocity and clicking Fire. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the statue?) If they disagree, look at your math again! 4: Set the initial velocity of the object to 20 m/s. Place the target at a range (distance) 20 m.a) Sketch the situation.d) Predict the height from which you have to launch the object in order for it to land on the target (calculate this & show all work).b) Perform the experiment by raising the cannon to the predicted height and clicking Fire! Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?) If they disagree, look at your math again!

uminum and steel. The company has available 38 comma 160 units of steel and 48 comma 380 units of aluminum. The​ 1-, 3-, and​ 10-speed models​ need, respectively, 8​, 12 and 16 units of steel and 15​, 10​, and 20 units of aluminum. The company makes ​\$4 per​ 1-speed bike, ​\$6 per​ 3-speed, and ​\$16 per​ 10-speed. Use the simplex method to complete parts​ (a) and​ (b). ​(a) How many of each type of bicycle should be made in order to maximize​ profit? What is the maximum​ profit? Set up the linear programming problem. Let x 1​, x 2​, and x 3 represent the numbers of​ 1-, 3-, and​ 10-speed bicycles,​ respectively, and let z be the total profit. ▼ Minimize Maximize zequals nothing subject to 8 x 1 plus 12 x 2 plus 16 x 3 ▼ greater than less than or equals greater than or equals less than nothing 15 x 1 plus 10 x 2 plus 20 x 3 ▼ greater than less than or equals less than greater than or equals nothing x 1greater than or equals​0, x 2greater than or equals​0, x 3greater than or equals0. ​(Do not factor. Do not include the​ \$ symbol in your​ answers.) Set up the initial simplex tableau and use the Simplex Method to solve. The maximum profit is ​\$ nothing. To get that​ profit, the company should make nothing ​1-speed bicycle(s), nothing ​3-speed bicycle(s), and nothing ​10-speed bicycle(s). ​(Type whole​ numbers.) ​(b) Explain what the values of the slack variables in the optimal solution mean in the context of the problem. Select the correct choice below​ and, if​ necessary, fill in the answer​ box(es) to complete your choice. A. When the profit is​ maximized, all of the steel is used but nothing units of aluminum remain unused. ​(Type a whole​ number.) B. When the profit is​ maximized, some of each material remains unused.​ Specifically, nothing units of aluminum and nothing units of steel remain unused. ​(Type whole​ numbers.) C. When the profit is​ maximized, all of the available aluminum and steel is used. D. When the profit is​ maximized, all of the aluminum is used but nothing units of steel remain unused. ​(Type a whole​ number.)
