<u>Step-by-step explanation:</u>
An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign. If the quadratic polynomial = 0, it forms a quadratic equation. Therefore, the standard form of a quadratic equation can be written as: ax² + bx + c = 0 ; where x is an unknown variable, and a, b, c are constants with 'a' ≠ 0 (if a = 0, then it becomes a linear equation).An equation with a degree of 2 is a quadratic polynomial , which means having a maximum of degree 2 .
Given below are some examples of equation with a degree of 2 :
6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0

Answer:
D
Step-by-step explanation:
Since there is a y on both and only an x on one the only logical one would be D
Answer:
1.7
Step-by-step explanation:
Adding together all the points, you get 10. 10 divided by 7 is 1.666666667, which rounds to 1.7
Answer:
8 classes
Step-by-step explanation:
Given
Required
The number of class
To calculate the number of class, the following must be true
Where k is the number of classes
So, we have:
Take logarithm of both sides
Apply law of logarithm
Divide both sides by log(2)
Round up to get the least number of classes
