Answer:
P(x) = -1/2(x -3)²(x +3)
Step-by-step explanation:
When q is a root of the polynomial, (x-q) is a factor. This polynomial will be ...
P(x) = a(x -3)²(x +3)
For x=0, the y-intercept will be ...
P(0) = 27a = -13.5
Then the value of a is ...
a = -13.5/27 = -1/2
The formula for P(x) is ...
P(x) = -1/2(x -3)²(x +3) . . . . . . factored form
P(x) = -0.5x³ +1.5x² +4.5x -13.5 . . . . standard form
<u>Given</u>:
The given triangle is a right angled triangle.
The length of the hypotenuse is 17 units.
One of the legs of the triangle measure x units.
The one of the angles of the right triangle is 60°
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the trigonometric ratio.
Thus, we have;
Substituting ,
and
in the above formula, we get;
Multiplying both sides of the equation by 17, we get;
Simplifying, we get;
Multiplying, we get;
Rounding off to the nearest tenth, we get;
Thus, the value of x is 14.7
