Vera claimed the solution set on the number line represents the inequality negative 78. greater-than-or-equal-to x. a number line going from negative 82 to negative 78. a closed circle is at negative 79. everything to the left of the circle is shaded. which error did vera make? vera wrote the inequality with the variable on the left side of the relation symbol. vera wrote a relation symbol that does not represent the direction of the ray. vera selected an inequality that does not include –79 in its solution set. vera used the wrong number in her inequality.

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?
