Answers

The total amount of profit that he was able to gain out of his 450 shares is 2,205. In the problem, it states that for ever share he earns $5 dollars each.in order to derive the total amount of profit he got from his shares, we multiply 450 shares and $5.
so, 450*5 is equals to $2,205.

What are the real and complex solutions of the polynomial equation x^3-8=0

Answers

this is a difference of two cubes equation. To solve it, use this formula:

(a^3-b^3) = (a-b)(a^2+2ab+b^2)

or

x^3-8 = (x-2)(x^2+4x+4)
x³ - 8 = 0

x³ = 0 + 8

x³ = 8

Take the cube root of both sides

∛x³ = ∛8

∛(x*x*x) = ∛(2*2*2)

x = 2

Which equation represents this number sentence?Fourteen more than the quotient of a number and 5 is 23.

Answers

Answer:

The answer to your question is: the second option

Step-by-step explanation:

a) This is not the right answer, the sentence to this option could be: fourteen more than the quotient of five and a number is 23.

b) This is the right option, the sentence is given in the description.

c)  This is not the right answer, the sentence to thi option could be: the quotient of fourteen plus a number and five is 23.

d) This is not the right answer, the sentence of this option could be: the quotient of five and the addition of a number and fourteen is 23.

Final answer:

The equation representing the given number sentence is x/5 + 14 = 23.

Explanation:

The number sentence is "Fourteen more than the quotient of a number and 5 is 23." To represent this as an equation, we need to translate the words into mathematical symbols. Let's say the number is represented by x. The quotient of a number and 5 is x/5. Fourteen more than x/5 is x/5 + 14. So, the equation representing the number sentence is x/5 + 14 = 23.

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?

Answers

f(x) = 4 - x²    g(x) = 6x

(g - f)(x) = g(x) - f(x)

(g - f)(3) = g(3) - f(3)

g(x) = 6x

g(3) = 6*3 = 18

f(x) = 4 - x²

f(3) = 4 - 3² = 4 - 9 = -5

(g - f)(3) = g(3) - f(3) = 18 - (-5) = 18 + 5 = 23

 (g - f)(3) = 23
