I will giev you branilest! Usain Bolt, an Olympic sprinter, ran LaTeX: 9\frac{4}{15}9 4 15miles in LaTeX: \frac{1}{3}1 3of an hour. A domestic cat runs LaTeX: 3\frac{3}{4}3 3 4miles in LaTeX: \frac{1}{8}1 8of an hour.

Would Usain Bolt or a domestic cat win a race that was 2 miles long?

(This question is assuming that each ran at a constant pace and actually stayed on the race track.)

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

Which expression is a factor of 12x2 + 29x – 8? x – 8 2x – 1 3x + 8 4x + 1

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?
