Question textConsider a spacecraft approaching a distant asteroid. The spacecraft’s distance d (km) from the asteroid over time t (seconds) can be approximated by the equation: [math: d(t)=807.1758e−0.0011t]a) Use the bisection method with the initial guesses of 500s and 1000s and a precision of 1e-6 to estimate the time it will take for the spacecraft to reach 300 km from the asteroid.Answer 1 Question 3[input] s (to 2 decimal places)b) The spacecraft needs to activate its landing procedure when it is 70km from the asteroid’s surface. Use the false position method with the initial guesses of 2000s and 2500s and a precision of 1e-6 to estimate the time at which the landing procedure needs to be activated.Answer 2 Question 3[input] s (to 2 decimal places)Check Question 3

Question at position 13 If you are using scipy.optimize.fsolve to solve the equation e−x=2−x, which of the following is the WORST initial guess to provide to fsolve? Hint: a sketch could help.All of the above are equally good initial guesses.0.0-1.02.01.0

Find all the roots of the function. Use preliminary analysis and graphing to determine good initial approximations. Round to six decimal places. f(x) = csc x - 2x on [0, 4]
