What is the measure of arc xy

Answer:
A.
Step-by-step explanation:
We have been given an image of a circle and we are asked to find the measure of arc XY.
We will use intersecting secants theorem to solve our given problem, which states that measure of an angle formed inside a circle by two intersecting secants is half the sum of intercepted arcs.
So we can set an equation to find the measure of arc XY as:
Therefore, measure of arc XY will be 46 degrees as well and option A is the correct choice.

Answer:
Step-by-step explanation:
No. of days of study = 6
Amount of food to use for the 6 days = 72 mm
Given that equal amount of food was used each day, amount used per day =
This would enable us derive a function for the amount of food remaining f(x), which can be expressed as a function of the number of days that have passed, (x).
Thus, we would have:
Let's check if this equation expresses the relation of the function well.
At the end of day 1, if we used, 12mm, we would have 72 - 12 = 60mm of food remaining.
If we replace x in the equation we derived, we would get the same 60mm as the amount of food remaining.
If you try 2, 3, 4, 5 days, you'd get same thing.
At the end of the study, after the 6th day, the food would remain nothing.
Replace 6 for x in the relation function derived, you'd get a value of 0.
