The roots of a polynomial function tells us about the position of the equation on a graph and the roots also tells us about the complex and imaginary roots. So, Roots of chords are similar to the roots of polynomial functions.
A real root of a polynomial function is the point where the graph crosses the x-axis (also known as a zero or solution). For example, the root of y=x^2 is at x=0.
Roots can also be complex in the form a + bi (where a and b are real numbers and i is the square root of -1) and not cross the x-axis. Imaginary roots of a quadratic function can be found using the quadratic formula.
A root can tell you multiply things about a graph. For example, if a root is (3,0), then the graph crosses the x-axis at x=3. The complex conjugate root theorem states that if there is one complex root a + bi, then a - bi is also a complex root of the polynomial. So if you are given a quadratic function (must have 2 roots), and one of them is given as complex, then you know the other is also complex and therefore the graph does not cross the x-axis.
So, The roots of a polynomial function tells us about the position of the equation on a graph and the roots also tells us about the complex and imaginary roots. So, Roots of chords are similar to the roots of polynomial functions.

Answer: 35%
Step-by-step explanation:
Percent of down payment
= 70,000 / 200,000 * 100
= 0.35 * 100
= 35%
<em>$70,000 is 35% of the purchase price of $200,000.</em>
I believe your answer may be .5
Answer:
45
Step-by-step explanation:
Let the first term be a and the common difference be d.
So -18=4a+6d and -9=6a+15d. Solving this we get a=-9 and d=3.
So the sum of first 10 terms is 5*(2*(-9)+9*(3))=45
#1: -13
#2: 169
#3: 56.333...
hope this helps xoxo
