First you need to find out how long she worked

7:32 to 3:43 is 8 hours and 11 minutes.

Multiply 6.75(her per hour salary) by 8 and you have $54. But you still have 11 minutes. 11 minutes is roughly 18.33% of an hour. So multiply 6.75 by 0.18 which is 1.25. Your answer is $55.24

Ye Li drew a quadrilateral that is both a rectangle and a rhombus. Name the quadrilateral and describe it using the properties o
son4ous [18]
We must look first for the properties given, so we have:
Rectangle - four sides, two pairs of opposite sides are parallel, four right anglesQuadrilateral - a four-sided figureRhombus - four sides, two pairs of opposite sides are parallel, all sides equal
So we're finding for a shape that has four sides that are all equal, with two pairs of parallel sides, and has four right angles. So from this description, we can say that it is a square. Squares have two pairs of parallel sides (like a rhombus and rectangle), four right angles (like rectangles), and four sides that are equal (like a rhombus). A square is also both a rectangle and a rhombus.

Find the average rate of change for f(x) = x2 − 3x − 10 from x = 4 to x = 6
cluponka [151]
I believe you meant f(x) = x^2 - 3x - 10.
                                                              f(b) - f(a)
The ave. r. of c. formula is     a. r. c = -----------------
                                                                 b -a
                               (6)^2 - 3(6) - 10 - [(4)^2 - 3(4) - 10]
Here,   a. r. c. =   ------------------------------------------------------        
                                                      6-4
                                           36 - 18 -10 - 16 + 12 + 10
     ... which comes out to ---------------------------------------
                                                                2

                a. r. c. = 7             for x^2 - 3x - 10 on the interval [4,6]
