in urgent need with help on these three What point on the line y-7x + 8 is closest to the origin? Let D be the distance between the two points. What is the objective function in terms of the x-coordinate? (Type an expression.) a. Find the radius and height of a cylindrical soda can with a volume of 398 cm3 that minimize the surface area. b. Compare your answer in part (a) to a real soda can, which has a...
I just need help with part c) please/thank you A solid brass ball of mass 20.9 g and radius 8.37 mm rolls smoothly along a loop-the-loop track when released from rest from a tall ramp leading to the loop-the-loop. The circular loop has a 12 cm radius. (a) What is the minimum height from which you can release the ball so that it will go around the loop-the-loop without falling off? 32.4 cm Correct: Your answer is correct. For part...
Please, someone can help to solve this tricky question? Score! 07120 U12 drswereu Question 1 < > 10 pts 5 1 28 Details Textbook Videos [+] A box with a square base and open top must have a volume of 364500 cm. We wish to find the dimensions of the box that minimize the amount of material used. First, find a formula for the surface area of the box in terms of only 2, the length of one side of...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
