Answer:
Step-by-step explanation:
There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form for some constant a.
To find a, we can substitute the coordinates of the y-intercept, (0, -50).
So,
Answer:
Step-by-step explanation:
The Universal Set, n(U)=2092
Let the number who take all three subjects,
Note that in the Venn Diagram, we have subtracted from each of the intersection of two sets.
The next step is to determine the number of students who study only each of the courses.
These values are substituted in the second Venn diagram
Adding up all the values
2092=[1106+x]+[103-x]+x+[23-x]+[762+x]+[14-x]+[77+x]
2092=2085+x
x=2092-2085
x=7
The number of students who have taken courses in all three subjects,
