Part 2: Solve a real-world problem using a square root function. When Isabel began her book-selling business, she stored her inventory in her garage. Now that her
business has grown, she wants to rent warehouse space. Lisa owns a large warehouse nearby and can
rent space to Isabel. The area of the warehouse is 8,100 square feet. Lisa is willing to rent Isabel as little
as 100 square feet of the space or up to as much as the entire warehouse. Her only requirement is that
all spaces must be square.
The total length of each row of bookshelves will be of the length of the storage space.
a) Let x be the area of the space that Isabel rents and f(x) represent the total length of a row of
bookshelves. How would you find the length of a row of bookshelves? (3 points)
IS
b) Write a function that expresses f(x). (10 points)
c) Graph the function. (10 points)

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
