Imagine that you are taking a multiple-choice quiz written in Icelandic and must guess randomly. Each question has 3 choices and 1 correct answer. Calculate the probability that you a. answer the first question incorrectly.
b. answer the first 2 questions incorrectly.
c. answer the first 5 questions incorrectly.
d. answer at least 1 of the first 5 questions correctly.

Explain how you do each step what term makes it inconsistent y=2x - 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?

Taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor with some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)= 2x+1 g(x)= 2x^2+1
