Answer:
The last graph.
Step-by-step explanation:
The last graph because it shows the continum of time, and it shows him getting closer to the school (decrease in distance), then it shows him picking up Janet (staying constant), then it shows him going back home to grab his books (increase in distance), all as time goes on.
Answer:
g(n) = 2n^2 - 4n; Find g(-9)
The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.
P-Parentheses
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction
Step-by-step explanation:
g(-9) = 2(-9)^2 - 4(-9)
g(-9) = 18^2 -4(-9)
g(-9) = 134+36
g(-9) = 170
I really hope this helps!

Since a calculator is involved in finding the answer, it makes sense to me to use a calculator capable of adding vectors.
The airplane's ground speed is 158 mph, and its heading is 205.3°.
_____
A diagram can be helpful. You have enough information to determine two sides of a triangle and the angle between them. This makes using the Law of Cosines feasible for determining the resultant (r) of adding the two vectors.
.. r^2 = 165^2 +15^2 -2*165*15*cos(60°) = 24975
.. r = √24975 ≈ 158.03
Then the angle β between the plane's heading and its actual direction can be found from the Law of Sines
.. β = arcsin(15/158.03*sin(60°)) = 4.7°
Thus the actual direction of the airplane is 210° -4.7° = 205.3°.
The ground speed and course of the plane are 158 mph @ 205.3°.
Answer:
1 mile=o.oo621371 meters
Step-by-step explanation: with that the answer would be 0.497097
use a divider to find the length of the middle line then use
