Answer:
12.4
Step-by-step explanation:
using x= 9tan54 the results is 12.38743728 but 12.4 to the nearest tenth
D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.
Answer:
see below
Step-by-step explanation:
The variables are listed top down in the variable vector in the same order as the coefficients are listed left-to-right in the equations. Each of the equations needs to have the variables listed in the same order.
