If a polynomial function f(x) has roots –8, 1, and 6i, what must also be a root of f(x)?

Answers

Answer 1

Answer: The polynomial given is in fourth degree with four roots. If one of the given roots is an imaginary number, in this case 6i, the missing root is its conjugate. Thus, the last unknown root of the polynomial is -6i.

What is calories ???

Answers

Answer and Step-by-step explanation:

Calories, in the realm of nutrition, represent units of energy derived from food and beverages. Specifically, we refer to kilocalories, denoting the energy required to raise the temperature of one kilogram of water by one degree Celsius. These units quantify the potential energy our bodies extract from consumed food, fueling essential physiological functions such as metabolism, movement, and overall bodily maintenance. It's essential to recognize that the caloric content varies among macronutrients; fats, proteins, and carbohydrates offer differing amounts of energy per gram. Monitoring calorie intake and expenditure plays a pivotal role in weight management, where achieving a balance between calories consumed and calories burned through physical activity is a key consideration.

Answer:

Step-by-step explanation:

Given

f(x) = $(3+x)/(x-3)$

To evaluate f(a + 2), substitute x = a + 2 into f(x)

f(a + 2) = $(3+a+2)/(a+2-3)$ = $(5+a)/(a-1)$ → A

Given f(t)=t to the power of 4 +t² -5, find the value of f(b) - f(-b)

Answers

$f(t)=t^4+t^2-5\n \n f(b)-f(-b)=b^4+b^2-5-[(-b)^4+(-b)^2-5]\n \n f(b)-f(-b)=b^4+b^2-5-b^4-b^2+5\n \n \boxed{f(b)-f(-b)=0}$

$f(b)-f(-b)=b^4+b^2-5-((-b)^4+(-b)^2-5)\n f(b)-f(-b)=b^4+b^2-5-(b^4+b^2-5)\n f(b)-f(-b)=b^4+b^2-5-b^4-b^2+5\n f(b)-f(-b)=0$

After answering the presented question, we can conclude that As a result, the system of equations solution is (3, 35).

What is equation?

An equation is a mathematical statement that validates the equivalent of two expressions joined by the equal symbol '='. For instance, 2x - 5 = 13. 2x-5 and 13 are two examples of expressions. The character '=' connects the two expressions. An equation is a mathematical formula that has two algebras on each side of an assignment operator (=). It demonstrates the equivalency link between the left and middle formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

Thus the first month's savings would be: (Regular price) - (Discounted price) = (151 + 20) - (101 + 5) = $20.

Part C: Using the equations from Parts A and B, we can construct the following system of equations:

Y = 10X + 5 (Discounted pricing equation) (Discounted price equation)

Y = 15X + 20 (Normal price equation) (Regular price equation)

We can solve this system by substituting one equation for the other:

10X + 5 = 15X + 20

When we simplify this equation, we get:

5X = 15

X = 3

Then we can plug X = 3 into either equation to determine the value of Y:

Y = 10(3) + 5 = 35

As a result, the system of equations solution is (3, 35).

The correct question is -

Justin is joining a gym the gym is offering a discount on the fee to join and on the monthly rate the discounted price in dollars the gym charges can be represented by the equation Y equals 10 X +5

Part A what are the slope and the Y intercept of the equation what do the slope and y-intercept each represent in this situation ?.

Part B the regular price in dollar the gym charges can be represented by the equation Y equals 15 X +20. How much money in dollars does Justin save the first month by joining the gym at the discounted price rather than the regular price

Part C Justin create a system of equation based on the equation from part a and the equation from part B, the solution to the system of equation is (-3, -25) Why is the point (-3, ,-25) not possible solution in this solution ?
