The factor that could be part of the function so that f (x) decreases as x approaches infinity and as x approaches negative infinity is -(x + 4).

The function f(x) decreases as x approaches infinity and as x approaches negative infinity if and only if the degree of the polynomial in the denominator is greater than the degree of the polynomial in the numerator. This means that the factor that completes the function f(x) = (3x + 1)(2x - 5)(x + 9)

Let us analyze each of the factors:

(3x + 1) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(2x - 5) is also a linear factor that does not help in decreasing function as x approaches infinity and as x approaches negative infinity.

(x + 9) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(-4) is a constant term that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(-2/3x) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

5x² is a quadratic factor that is of degree 2 and thus does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(3x-7) is also a quadratic factor that is of degree 2 and thus does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

-(x + 4) is a linear factor of degree 1 and it helps in decreasing the function as x approaches infinity and as x approaches negative infinity.

The true statement is: "Octave is the name of a particular interval size."

In music theory, an octave refers to the interval between two pitches where the higher pitch has a frequency that is exactly twice that of the lower pitch. It represents a doubling or halving of the frequency. For example, if we start on the note A and move up to the next A, we have traversed an octave.

An interval, on the other hand, refers to the distance between two pitches. It is the numerical representation of the difference in pitch between two notes.

The statement mentioning "interval as the name of a particular octave size" is incorrect because the octave is a specific interval size, not the other way around.

The statement suggesting that "the fifth is a kind of octave" is also incorrect. The fifth is a specific interval that represents the distance of five diatonic scale steps between two pitches.

Lastly, the statement that "a synonym for distance is octave" is not true. While an octave represents a specific interval size, the term "distance" is a more general term that can refer to the measurement between any two pitches, regardless of the specific interval size.

Answer:

1.26 feets

Step-by-step explanation:

Given the following :

Vertex (0, 0)

Focus of reflector = 6 feets

Extension = 5.5 feets

Equation to obtain conic section of a parabola:

(x - h)² = 4p(y - k)

Vertex (0, 0)

h =0 ; k = 0, p = 6, x = 5.5

(5.5 - 0)² = 4*6(y - 0)

30.25 - 0 = 24(y - 0)

30.25 = 24y

y = 30.25 / 24

y = 1.26

Hence, depth of reflector = 1.26 feets

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

m < PCA = m  < CAD ( alternate angles)

m < BAD = m <CAD ( given)

Also m < CAB = m < PCA + m < CPA  ( exterior angle of a triangle theorem).

Also m < CAB = m< CAD + m < BAD (given)

So  m < PCA + m < CPA =  m < CAD + m < BAD

But m < PCA = m  < CAD

so  m < CAD + m < CPA = m < CAD + m BAD

So m < CPA = m < BAD

But m < PCA = m < CAD = m BAD

therefore m < CPA = m < PCA

That makes triangle CAP isosceles

Therefore AP = AC.

Step-by-step explanation:

it may help you to understand

The domain of each function is determined by the values of x for which the function is defined. The domain of function a) f(x) = x²-3x-4 is all real numbers. The domain of function b) f(x) = 2x-3 is all real numbers. The domain of function c) M(x) = √(x-5) is x ≥ 5. The domain of function d) g(x) = (x+9)/(x-4) is x ≠ 4. The domain of function e) h(x) = 16/(2x-5) is x ≠ 2.

a) The function f(x) = x²-3x-4 is a polynomials function, and polynomial functions are defined for all real numbers. Therefore, the domain of f(x) is all real numbers.

b) The function f(x) = 2x-3 is a linear function, and linear functions are defined for all real numbers. Hence, the domain of f(x) is all real numbers.

c) The function M(x) = √(x-5) represents a square-root function. Square root functions are defined only for non-negative values inside the square root. In this case, x-5 must be greater than or equal to zero, which implies x ≥ 5. Therefore, the domain of M(x) is x ≥ 5.

d) The function g(x) = (x+9)/(x-4) is a rational function. Rational functions are defined for all real numbers except the values that make the denominator equal to zero. In this case, the denominator is x-4, so the function is undefined when x = 4. Hence, the domain of g(x) is x ≠ 4.

e) The function h(x) = 16/(2x-5) is also a rational function. Similar to the previous explanation, rational functions are defined for all real numbers except the values that make the denominator equal to zero. In this case, the denominator is 2x-5, so the function is undefined when x = 5/2. Therefore, the domain of h(x) is x ≠ 5/2 or x ≠ 2.

A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the length of side )

Here A = 9[tex]\sqrt{3}[/tex] , thus

[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 9[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )

s²[tex]\sqrt{3}[/tex] = 36[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

We have all the zeros of the polynomial. Therefore, there are no remaining zeros of f(x). The given polynomial f(x) is a degree 4 polynomial. The given zeros of f(x) are `3-5i`, `4i`, `3+5i` and `4-i`.

We have to find the remaining zeros of f.

The remaining zeros of f are the solutions of f(x) = 0 which are not given in the question. Degree of polynomial = 4

We are given all the four zeros of the given polynomial.

So, we can write the expression for f(x) by using all these zeros.

f(x) = a(x - 3 + 5i)(x - 3 - 5i)(x - 4i)(x - 4 + i) [Using the zero factor property]

Now, we have to find the remaining zeros.

Let's find it out :f(x) = a(x - 3 + 5i)(x - 3 - 5i)(x - 4i)(x - 4 + i)f(x)

= a[(x - 3)² - (5i)²][(x - 4)² - (i)²]

(Using a² - b² = (a + b)(a - b))f(x)

= a[(x - 3)² + 25][(x - 4)² + 1] (Since i² = -1)f(x)

= a(x² - 6x + 34)(x² - 8x + 17)f(x)

= a[x⁴ - 14x² + 33x + 612] (Expanding the above expression)

The polynomial f(x) is a degree 4 polynomial.

Hence, we have all the zeros of the polynomial. Therefore, there are no remaining zeros of f(x).

The probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes is found as  `0.7475`. Hence, the option D is correct.

The length of time it takes a college student to find a parking spot in the library parking lot follows a normal distribution with a mean of 2.5 minutes and a standard deviation of 0.75 minute.

We are supposed to find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes.

So, we need to find `P(x < 3)` where `x` is the time taken to find a parking spot in the library parking lot.

Now, z-score will be

`z = (3 - 2.5)/0.75

= 0.67`

By looking at the z-score table, the probability that corresponds to z = 0.67 is 0.2514.

Therefore,

`P(x < 3) = P(z < 0.67)

= 0.2514 + 0.5

= 0.7514

≈ 0.7475 (approx)`

So, the correct option is `0.7475`. Hence, the answer is option D.
