The factor of the 18x^{2} -21x-15 will be 3(3x-5)(2x+1).

<h3>What will be the factor of  18x^{2} -21x-15 ?</h3>

Given quadratic equation is 18x^{2} -21x-15

By taking 3 common from whole of the equation it becomes.

3(6x^{2} -7x-5)

now by factorization equation will be.

3(6x^{2} -10x+3x-5)

3[(2x(3x-5)+1(3x-5)]

Taking (3x-5) common from whole equation it will become

3(3x-5)(2x+1).

Hence the factor of the 18x^{2} -21x-15 will be 3(3x-5)(2x+1).

To know more about factorization follow.

In a survey of 200 professors at Gotham University, professors were asked, “Regarding your weight, do you think you are: About r
DochEvi [55]

The probability that a randomly selected professor is female and feels "About Right" is 0.40

The distribution table :

____About right _ Oweight _ Uweight __ Total

Female _ 80 _____ 39 ______ 3 _______ 122

Male ___ 52 _____ 10 ______ 16 _______ 88

Total ___ 132 ____ 49 ______ 19 _______ 200

Oweight = Overweight

Uweight = Underweight

Recall :

Probability = required outcome / Total possible outcomes

Probability that a selected professor is female and feels 'About right' :

Required outcome = number of female professors who feels 'About right' = 80

Total number of professors = 200

Hence,

P(Female and 'About right') = 80/200 = 0.40

An observer on the ground is x meters from the base of the launch pad of a rocket, which is at the same level as the observer. A
Firlakuza [10]
This can be solved using trigonometric functions. The distance x serves as one leg of a triangle, and makes an angle q with the hypotenuse. The distance from the tip of the rocket to the ground make up the other leg of the triangle. So solving this:

tan q = y / x

Where: y = distance from the tip of the rocket to the ground

Therefore, y = x tan q

Among the choices, the correct answer is C.
