Ok So From What You Said I Calculated This:
1:00-2:00
cars=c, trucks=t
answer=a
c x 3 = a
a÷3=t
F(-2)= -12
Explanation: 2(-2) = -4
-4 - 8 = -12
“d”
you know b cannot work because the x is raised to the x^2 which would be a diff graph
a does not work because -x^3 the graph would be flipped
c is incorrect because the five is in the negative region; not positive
There is no rate of change, they both represent you burning 400 calories per hour.
Answer:
x ≈ 42.3
Step-by-step explanation:
The law of cosines is given. For this problem, ...
a = 25, b = 30, c = x , C = 100°
Filling in these values, we have ...
x^2 = 25^2 +30^2 -2(25)(30)cos(100°)
x^2 ≈ 1785.4723
x ≈ √1785.4723 . . . . take the square root
x ≈ 42.3
