Question 2 Open the graphing tool, and select the data tab. Copy and paste your data from the table (x- and y-coordinates). Don’t include any dollar signs. Plot the data on the graph.

Under the relationship tab, use the linear, exponential, and quadratic function tools with “best fit” selected to view the regression model. Zooming in and out will help you get a better view of each fit. Observe how well each model fits the data. Rank the three function types (linear, exponential, quadratic) in order from best fit to worst fit.

Write two to three sentences justifying your reasoning for the ranking you chose in question 2.

Factor the polynomial. b^2 + 4b + 4

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?

Which of the following choices gives you a slope of 3?
