Answer:
The roots (zeros) of the function are:

Step-by-step explanation:
Given the function

substitute f(x) = 0 to determine the zeros of the function

First break the expression x² + 3x - 40 into groups
x² + 3x - 40 = (x² - 5x) + (8x - 40)
Factor out x from x² - 5x: x(x - 5)
Factor out 8 from 8x - 40: 8(x - 5)
Thus, the expression becomes

switch the sides

Factor out common term x - 5

Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)

Solve x - 5 = 0
x - 5 = 0
adding 5 to both sides
x - 5 + 5 = 0 + 5
x = 5
solve x + 8 = 0
x + 8 = 0
subtracting 8 from both sides
x + 8 - 8 = 0 - 8
x = -8
Therefore, the roots (zeros) of the function are:

Answer: C.
Not symmetric; not bell-shaped
Step-by-step explanation:
Data is mainly right skewed. In simpler terms the data has more if a "tail" on the right side while most of the data is on the left. If you were to trace a line over each last dot (the one's at the top) all the way to the last point. You would see that it does not make a "bell-shape" but more of the shape of an arrow pointing left. If it were symmetrical it would have more of a balanced amount of data points on it's opposite side which would make the shape either look like a triangle or a bell shape. Hope that helps.
A) Simple interest note proceeds are equal to the face value: $18,235.
b) Simple discount note proceeds are the face value less the inerest due,
.. $18,235(1 -0.10*2) = $14,588.
