The answer can't be C or D because the unit of volume is always cubed. The formula for volume of cylinder is (pi)(r^2)(h) . The pi(r^2) part is the formula for area of a circle which is what the base of the cylinder is. Fortunately the area is already given as 28.2. Plug that into the volume formula and plug in 3.1 for the height and multiply. I get 87.42 and the answer choice B seems to be the closest option
With ϕ ≈ 1.61803 the golden ratio, we have 1/ϕ = ϕ - 1, so that
Replace :
Split the integral at x = 1. For the integral over [1, ∞), substitute :
The integrals involving tan⁻¹ disappear, and we're left with
Answer:
3 right and 1 up
Step-by-step explanation:
hope this helps!
The first graph. This is because the one solution is where the two lines will intersect.
In the second graph, the two lines are parallel, so there is no possible way for them to intersect. In the third graph, the two lines are on top of one another, so there’s more than one solution.
Therefore, the first graph is where there is one solution.
Yes I worked it in my brain hahahahahah
