If f(x)=7xe^x, find f'(x)

f(x) = 7xe x Using the product rule: [f'(x)=u*(dv/dx)+ v*(du/dx)]Let u=7x and v=e x Therefore, du/dx=7 and dv/dx=e x Hence, f'(x) = 7xe x + 7e x

Matt weighs 60kg and his son, Rob weighs 30kg. They both run a 100m race and finish the race running at 5m/s. Who has more Kinetic Energy at the end of the race?

Kinetic energy is given by the equation:K.E. = 0.5mv 2 Therefore Matt has Kinetic energy:K.E. (Matt) = 0.5*(60) (5) 2 = 750JAnd Rob has Kinetic energy:K.E. (Rob) = 0.5 (30)*(5) 2 = 375JTherefore Matt has the...
