You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
Side XZ needs to be congruent to side AC. The answer is D.
Put that in google it will answer it for u
Answer:
<h3>
x = 6</h3><h3>
</h3>
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = 2
b = x/2
c = √13
<u>plugin values into the formula:</u>
2² + (x/2)² = (√13)²
4² + <u>x² </u>= 13
4
16 + x² = 13 (4)
x² = 52 - 16
x = √36
x = 6
