Lin launches a model rocket that follows a path given by the function y = −0.4t 2 + 3t + 0.5, where y is the height in meters and t is the time in seconds. a. Explain how you can write an equation and then use the discriminant to determine whether Lin's rocket ever reaches a height of 5 meters. b. If Lin's rocket reaches a height of 5 meters, at approximately what time(s) does it do so? If not, what is the rocket's maximum height?

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
