Answer:
Step-by-step explanation:
The vector in component form is the difference of the coordinates of its end points:
rock - ship = (4, 7) - (1, 0) = (3, 7) . . . . vector from ship to rock
__
The angle from North can be found using the tangent relation:
tan(bearing) = (east distance)/(north distance) = 3/7
bearing = arctan(3/7) ≈ 23.1986°
The bearing of the rock is 23.20°.
Let w represent the number of weeks Emma saves her money. Then we want to find w for
60 +22w ≥ 249
22w ≥ 189 . . . . . . . . . subtract 60
w ≥ 189/22 ≈ 8.591
Emma will have enough money after 9 weeks.

Answer:
(0.353, -48)
Step-by-step explanation:
dy/dx = 9x² + 28x - 11 = 0
Using the quadratic formula:
x = -3.46 and 0.353
d²y/dx² = 18x + 28
Minima when d²y/dx² is positive
x = 0.35284 or (-14+sqrt(295))/9
y = 3x³ + 14x² - 11x - 46
y = -48.00651351
