Answer: The boys made up 6b of the original class.
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
F ( x ) = 3 sim x + 3 cos x
f ` ( x ) = 3 cos x - 3 sin x
f `` ( x ) = - 3 sin x - 3 cos x = - 3 ( sin x + cos x )
The inflection points:
- 3 ( sin x + cos x ) = 0
sin x + cos x = 0
sin x = - cos x / : cos x
tan x = - 1
x 1 = 3π / 4
x 2 = 7π / 4
The function is concave up when f``(x) > 0
- 3( sin x+ cos x ) > 0
sin x + cos x < 0
tan x < - 1
f is concave up for:
x ∈ ( π/2, 3π/4 ) ∪ ( 3π/2, 7π/4)
f is concave down for:
x ∈ ( 0, π/2 ) ∪ ( 3π / 4, 3π/2 ) ∪ ( 7π / 4, 2 π ).
Answer:
355 bushels.
Step-by-step explanation:
To know the amount of wheat the truck hauls each trip, we need to divide the total amount of bushels of wheat between the total of trips of the truck.
The total amount of bushels is 4970 and the total of trips is 14.
Then, the amount of bushels for each trip would be 4970/14 = 355.
Therefore, the truck hauls 355 bushels of wheat each trip.
