I only know this much sorry .
A function is a relationship where each x-value is paired with exactly one y-value.
When looking at a graph, you want to ask yourself, "Can I find any two points on this graph that have the same x-value?"
I can see with x=8 that there would be two points on that graph with an x-value of 8, making this not a function.
People call this test "the vertical line test" because any vertical line really represents a single x-value. If any vertical line hits the graph more than once, the graph cannot be a function, because that value of x has more than one y-value.
Answer:
5.1cm
Step-by-step explanation:
volume of hemisphere = 1.07cm³
9.2-1.07 = 8.13
volume of cylinders = 8.13cm³
height of cylinder = 4.04cm
total height of gizmo = 4.04+0.8=4.84
4.84/sin(72) = 5.1cm
The answer is b because d represents how many days he practices
