Which of the following functions is graphed below?
2 answers:
Answer:
B. |x+6|-3
Step-by-step explanation:
Well we can tell by looking at the graph that the line has a y-intercept of +3,
meaning we can cross out choices A and C.
Now we can graph B and D,
Look at the image below ↓
By looking at the graphed lines we can tell that y = |x+6|-3 is the correct answer.
Wel can also conclude that choice B is correct because of its vertex being at (-6,-3).
<em>Thus,</em>
<em>answer choice B is the correct answer.</em>
<em>Hope this helps :)</em>

4 minutes 34 seconds will takes to empty the tank, if the starts completely full and oil drained at a rate of 2.5 per minute.
Step-by-step explanation:
The given is,
Tank is shaped like a cylinder that is 3 ft long with a diameter of 2.2 ft.
Oil drained at a rate of 2.5 per minute.
Step:1
Time taken to dry the oil tank is,
T = ....................................(1)
Step:2
Volume of the oil is,
.................................................(2)
Where, r - Radius of Cylinder
r = 1.1 ft
From eqn (1),
V = ×
× 3
= 11.40398
Step:3
From equation (1)
=
= 4.56
= 4.56 minutes
T = 4 minutes 34 seconds
Result:
Time taken to dry the oil tank is 4 minutes 34 seconds, if a cylinder is 3 ft long with a diameter of 2.2 ft and oil is drained at a rate of 2.5ft^3 per minute.
