- Using the Midpoint Formula Use the result of Exercise 53 to find the endpoint (x2,y2) of each line segment with the given endpoint (x1,y1) and midpoint (xm,ym). ax1,y1=1,2xm,ym=4,1bx1,y1=5,11xm,ym=2,4arrow_forwardCalculate the moments of inertia (Ix and Iy) of the shaded area given in the figure with respect to the given x and y axes. r(mm)=144 h(mm)=300arrow_forwardhand written plz Four particles in the (x, y)-plane are held together as a rigid body by a set of light rigid rods. The particles are as described in the following table: Particle Mass (kg) Position (m) 1 1 (1, 3) 2 2 (4,2) 3 1 (3,5) 4 2 (4,1) Enter an expression that gives the moment of inertia, I, of the rigid body about the line y = x in the box below (do not include any units in your answer). I= kg m²arrow_forward
- Tutor- Which one of the following equations is the equation of the tangent plane to the surface xy + xz + yz = 1 at the point (0, 1, 1) ? Ox-y-z= -2 Oy+z= 1 O xz + yz = 1 O 2(xy + xz + yz) – 2x – y – z = 0 O x = 0 O x + 2y + 2z = 4 O 2x + y + z = 2 O y+z= 2 O 3x + 2y + 2z = 4arrow_forwardMiniature train The following multifasti photograph shows a miniature train that moves steadily quickly on a straight horizontal track. As the machine moves, a marble is thrown into the air by means of a spring installed in the chimney of the locomotive. The marble continues to move the same speed forward to the machine, and returns to it a second after the launch. Measure the angle that the trajectory of the marble forms with the horizontal one and use the in. mation to determine the maximum height of the marble and the speed of the locomotive.arrow_forward١٣arrow_forward
