Write and solve a quadratic equation for the situation below. choose the answer that has both an equation that correctly models the situation as well as the correct solution for the situation.

suppose a model rocket is launched from a platform 2 ft above the ground with an initial upward velocity of 150 ft/s. how long will it take the rocket to hit the ground?

a)0= −16t^2+150t+2; t ≈ 9.4 seconds and t ≈-0.01 seconds

b)0= −16t^2+150t+2; t ≈ 9.4 seconds

c)2= −16t^2+150y+2; t ≈ 9.4 seconds

d)none of the choices are correct.

What signals you that factoring by grouping is the best method to use when factoring a problem?

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?

Analyze the graph of the cube root function shown on the right to determine the transformations of the parent function. then, determine the values of a, h, and k in the general equation.
