Use the Rational Root theorem to determine the factors of x^3 - 2x^2 - 13x - 10 given that one factor is (x + 1)
Answers
Answer:
The correct option is;
D. (x - 5)·(x + 2)·(x + 1)
Step-by-step explanation:
The Rational Root theorem is expressed mathematically as follows;
[tex]Possible \ rational \ roots = \dfrac{Factors \ of \ the \ constant \ term}{Factors \ of \ the \ leading \ coefficient}[/tex]
The given polynomial is presented as follows;
x³ - 2·x² - 13·x - 10
A factor of the polynomial = (x + 1)
The factors of the constant term, -10 = -10, -5, -2, -1, 10, 5, 2, and 1
The factors of the leading coefficient, (the coefficient of the variable having the highest degree or power, x³) = 1
Given that (x + 1) is a known factor, the other two factors are either (x + 5) and (x - 2) or (x - 5) and (x + 2)
The option, that combines (x + 1) and the other two factor combination is (x - 5)·(x + 2)·(x + 1)
∴ The solution which meets the condition is (x - 5)·(x + 2)·(x + 1)
We check;
(x - 5)·(x + 2)·(x + 1) = x³ - 2·x² - 13·x - 10

A straight road to the top of a hill is 2500 feet long and makes an angle of 12° with the horizontal. Find the height of the hill. Round to the nearest foot.
Answers
The height of the hill is 520 ft
The height of the hill, h the length of the road, L and the ground form a right angled triangle with length of the road as the hypotenuse side and the height of the hill as the opposite side to the angle the road makes with the horizontal, Ф.
Now, from trigonometric ratios,
sinФ = h/L
The height of the hillMaking h subject of the formula, we have
h = LsinФ
Since L = 2500 ft and Ф = 12°, thus
h = LsinФ
h = 2500 ft × sin12°
h = 2500 ft × 0.2079
h = 519.78 ft
h ≅ 520 ft to the nearest foot
So, the height of the hill is 520 ft

Answer:

Step-by-step explanation:
solved it
The value of f(7) is -1.73 for the function f(x)=3/(x+2)-√x-3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A relation is a function if it has only One y-value for each x-value.
The given function is f(x)=3/(x+2)-√x-3
We need to find the value of f(7)
Replace x with 7 in the given function.
f(7)=3/7+2 - √7-3
f(7)=3/11-√4
=3/11-2
=3-22/11
=-19/11
=-1.73
Hence, the value of f(7) is -1.73 for the function f(x)=3/(x+2)-√x-3.
