It is know that the data tabulated below can be modeled by the following equation y=(a+sqrt(x)/b*sqrt(x))^2 use a transformation to linearize this equation and then employ linear regression to determine a and b. based on your analysis, predict y at x=1.6. x = 0.5, 1, 2, 3, 4 y= 10.4, 5.8, 3.3 2.4, 2.

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?
