F(X)=-2x-3 g(X)=3X+1 find (fxg)(X)

Mathematics
1 answer:
Goshia [24]4 years ago
4 0

Answer:

6x² - 7x - 3

Step-by-step explanation:

(f × g)(x) = f(x) × g(x), that is

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

Each term in the second factor is multiplied by each term in the first factor, that is

2x(3x + 1) - 3(3x + 1) ← distribute both parenthesis

= 6x² + 2x - 9x - 3 ← collect like terms

= 6x² - 7x - 3

A physical education class has three times as many girls as boys. During a class basketball game, the girls average 18 points ea
BigorU [14]
Let the number of girls be g and the number of boys be b.
b = 3g
Class average = class score/class size = 17
17 = (class score) / 3g + g
68g = class score
Class score = girls score + boys score
Girls average = girls score/g
girls score = 18g
68g = 18g + boys score
boys score = 50g
Boys average = 50g/3g
= 16.7

balu736 [363]

Answer with explanation:

Number of Distinct Letters in English Alphabet = 26 Capital +26 Small

                                                 =52 Alphabets

Total Number of Distinct digits in number system = {0,1,2,3,4,5,6,7,8,9}=10

Account Number of Customers for a certain Company =3 Letters +2 Numbers

Out of 52 Alphabets , 3 Letters can be Chosen in

    =_{3}^{52}\textrm{P} ways, since Order of arranging of three alphabets is Important.

Similarly, out of 10 Digits , 2 numbers can be chosen in

      =_{2}^{10}\textrm{P} ways, since Order of arranging of three alphabets is Important.

Total Number of Possible Account number

         =_{3}^{52}\textrm{P} \times _{2}^{10}\textrm{P}\\\\=\frac{52!}{(52-3)!}\times \frac{10!}{(10-2)!}\\\\=\frac{52!}{(49)!}\times \frac{10!}{(8)!}\\\\=52\times 51 \times 50 \times 9 \times 10\\\\=11934000
