Answer:
103.65 mph
Step-by-step explanation:
A bearing of 250 deg is 200 deg on the coordinate plane.
Find the x- and y-components of the speed vectors. Add them. Then find the magnitude of the resultant.
Hx = 110 cos 200° = -103.366
Hy = 110 sin 200° = -37.622
Ax = 0
Ay = 30
Hx + Ax = -103.366
Hy + Ay = -37.622 + 30 = -7.622
sqrt(-103.366^2 + -7.622^2) = 103.65
Answer: 103.65 mph
ANSWER
EXPLANATION
If g(x) is the transformation of f(x) as follows,
Then g(x) is a horizontal compression (if a > 1) or stretch (if a < 1) of f(x). The rule to map each point is,
In this case, this is a stretch so the point (-2, 2) maps to the point (-4, 2) and the origin is the same. Join these two points with a line and we get the graph of f(¹/₂x).
(12+9x) - (6+3x) + 6x + -3
6+3x + 6x+-3
3+ 9x
