The velocity of a moving object v, in meters per second, is given by the formula below. The variable x is the kinetic energy of the object, in Joules,
and m is the mass of the object in kilograms.
V=
VA
A marble with a mass of 0.04 kilograms rolls down a ramp and reaches a maximum kinetic energy of 0.875 Joules.
Use the given formula to write a function, VX), that models the situation. Then, use the function to predict how the velocity of the marble
changes as it rolls down the ramp.

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.

Ebuka's monthly rent is $750. if ebuka pays the rent late, his landlord charges 4% interest per week that the payment is late. write a function that gives the total cost r(t), in dollars, of ebuka's rent if he pays it t weeks late.
