Answer:
1/2
Step-by-step explanation:
The factored form of the related polynomial is (x - 1)(x - 9)
<h3>How to determine the
factored form of the related polynomial?</h3>
In this question, the given parameter is the attached graph
From the graph, we can see that the curve crosses the x-axis at two different points
These points are the zeros of the polynomial function.
From the graph, the points are
x = 1 and x = 9
Set these points to 0
x - 1 = 0 and x - 9 = 0
Multiply the above equations
(x - 1)(x - 9) = 0
Remove the equation
(x - 1)(x - 9)
Hence, the factored form of the related polynomial is (x - 1)(x - 9)

Answer:
Step-by-step explanation:
Those are fractions, are they not? I'll treat them that way.
Find the lowest common denominator.
You need 1 three and 1 five.
2/5 = (2*3)/(5 * 3) = 6 / 15
2/3 = (2*5)/(3*5) = 10 /15
Just add the numerators.
It is reduced. There are other ways to write it
16/15 = 1 1/15 is one of them
Let
x--------------> ages of Raj
y--------------> age of Zia
we know that
x=y+3-------------> equation 1
x²+y²=369-----------> equation 2
<span>I substitute 1 in 2
</span>
(y+3)²+y²=369----------> y²+6y+9+y²=369---------> 2y²+6y-360=0
2y²+6y-360=0
using a graph tool-----------> to calculate the quadratic equation
see the attached figure
the solution is
y=12
x=y+3--------> x=12+3--------> x=15
the answer is
Raj is 15 years old
Zia is 12 years old
