Answer:
12,662 books
Step-by-step explanation:
Total number of books = 75,972
No. of science books = ⅓ of 75,972 = ⅓*75,972 = 25,324 books.
No. of business books = 75% of the remaining books = 75% of (75,972 - 25,324)
=
No. of business books = 37,986
No. of maths books in the math section = 75,972 - (25,324 + 37,986)
= 75,972 - 63,310
= 12,662 books
Answer:
x =8 is the equation of the tangent.
Step-by-step explanation:
Here the equation of the given circle is:
Now, comparing it with the general equation of circle:
we get the central coordinates (h,k) = (3,-2)
So, the slope of the line joining center and (8, -2) =
Since the slope of line = 0, line is parallel to x axis.
Now, as tangent and the line is perpendicular to each other
⇒Slope of the tangent = -1/ slope of the line =
Now, by point slope formula: the equation of the tangent is
(y-y0) = m (x-x0)
or,
or x =8 is the equation of the tangent.
