Find g (x) • h (x)
g (x) = 4x + 1 and h (x) = x^2 - 3
Answer:
[tex]g(x).h(x) = (4x + 1) \times ( {x}^{2} - 3) \\ = (4x + 1)( {x}^{2} - 3) \\ = 4 {x}^{3} - 12x + {x}^{2} - 3 \\ \\ { \boxed{ \boxed{g(x).h(x) = 4 {x}^{3} + {x}^{2} - 12x - 3 }}}[/tex]

The question is unclear. The sum
442 is one possibility. The way this reads, 6 is the sum of the tens and ones digit. Also 10s > ones. Given those parameters. I can't think of two many more possiblities -- maybe 451
So we have two numbers

Step-by-step explanation:
The revenue made by a motorcycle company from the sale of x motorcycles is given by 0.003x^2 + 9x. The cost to produce x motorcycles is given by the polynomial 13x+400,000. Form a polynomial expression written in simplified standard form for the profit from making and selling x motorcycles.
The profit expression from selling x motorcycles expressed as a polynomial is : -0.003x² + 4x + 400000
The value of profit cab be found using the expression :
Profit = (Cost of production - Revenue)
Profit = (Cost of production - Revenue) Cost of production = 13x + 400000
Profit = (Cost of production - Revenue) Cost of production = 13x + 400000Revenue = 0.003x² + 9x
Profit = (13x + 400000) - (0.003x² + 9x)
Profit = 13x + 400000 - 0.003x² - 9x
Profit = 13x - 9x + 400000 - 0.003x²
Profit = 4x + 400000 - 0.003x²
The polynomial in simplified standard form can be expressed thus : -0.003x² + 4x + 400000

If the zeros of a quadratic function are 3 and 8, what are the factors of the function? 3and (x – 3) B. (X- 8) and (x + 3) O C. (X + 8) and (x + 3) 00. (X - 8) and (x-3) Reset Next
Answer: Choice D
(x - 8) and (x - 3)
===============================================
Explanation:
The term "root" is the same as "zeros of a function".
If 3 is a root, then x = 3 leads to x-3 = 0 after subtracting 3 from both sides.
If 8 is a root, then x = 8 leads to x-8 = 0 for similar reasoning
Use of the zero product property allows us to combine those two rules into the following
(x-3)(x-8) = 0
This shows that the two factors are (x-8) and (x-3)
The order of the factors doesn't matter because we can multiply two numbers in any order.

P(x) = x^4+ax^3-x^2+bx-12 has factors of (x-2) and (x+1). Solve the equation P(x)=0
Answer:
because P(x) has factors of (x-2) and (x+1) => x = 2 and x = -1 are the solutions of P(x)
so we have:
[tex]\left \{ {{2^{4}+2^{3}a-2^{2}+2b-12 =0} \atop {1-a-1-b-12=0}} \right.\\=>\left \{ {{8a+2b=0} \atop {a+b=-12}} \right.\\<=>\left \{ {{4a+b=0} \atop {a+b=-12}} \right.\\<=>\left \{ {{a=4} \atop {b=-16}} \right.[/tex]

Write an 11-digit number that uses every digit at least once, and the value of the digit in the millions place is 10 times the value of the digit in the hundred thousands place. Explain what you did.
An 11 digit number which is a solution to the problem Giveb is 32,561,100,000
All we have to do is write out an 11 digit number such that the value in the 1 million place is 10 times the value in the 100,000 place.
32,561,100,000
Writing the value given in expanded form :
3 in 10 billion place = 30,000,000,000
2 in one billion place = 2,000,000,000
5 in 100 million place = 500,000,000
6 in 10 million place = 60,000,000
1 in 1 million place = 1,000,000
1 in 100 thousand place = 100,000
Comparing the value in the 1 million place and that in the 100 thousand place :
1,000,000 / 100,000 = 10
This means that the value in the 1 million place is 10 times the value in the 100,000 place.
