If f(x) = 2x^2+ 1 and g(x) =x^2 - 7, find (f – g)(x).
O A. 3x2 + 8
B. 3x2 - 6
C. x2 - 6
D. x2 + 8
Answer:
x2 + 8
Step-by-step explanation:
The value of the composite function (f - g)(x) is x² + 8.
The correct option is D.
What is a composite function?Any function that is created by combining two or more other functions is referred to as a composite function. To put it another way, given two functions, f, and g, the composite function of f and g, denoted as f(g(x)), is a new function that applies g to the input x before applying f to the output of g (x).
Given:
f(x) = 2x² + 1 and g(x) = x² - 7.
To find (f – g)(x), we need to subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x)
where f(x) = 2x² + 1 and g(x) = x² - 7.
Substituting these expressions into the equation, we get:
(f - g)(x) = (2x² + 1) - (x² - 7)
Simplifying the expression on the right-hand side by distributing the negative sign, we get:
(f - g)(x) = 2x² + 1 - x² - 7)
Combining like terms, we get:
(f - g)(x) = x² + 8.
Therefore, (f - g)(x) = x² + 8.

If only two points are needed to determine a line why are three ordered pair solutions or points found for a linear equation
For any two points that we have, we can find a line that passes through them, so the first part is true, only two points are needed to determine a line.
Then you say:
"why are three ordered pair solutions or points found for a linear equation"
A linear equation is something of the form:
y = a*x + b
Where we assume that you know a and b.
Given that case, we can see that we have infinite solutions.
Suppose that you want to solve this for y, then for each possible value of x you will have a different solution, and you can have infinite values of x there, so there are infinite solutions.
Now, what I think you are asking is:
Why we should use 3 points to check if a relation is linear or not?
Well, exactly for the first thing you said. We always can find a line that passes through two given points, but that is not the case for 3 given points.
So, if in a given relation we use 3 points, and we can see that these are collinear, then we can conclude that the relationship gives a linear equation (ideally you could use more than 3 points, but usually is enough)

The value of the arithmetic series is 550. The correct answer is C) 550.
To evaluate the arithmetic series, we can use the formula:
Sn = (n/2)(2a1 + (n-1)d)
Given:
a1 = 10 (first term)
d = 8 (common difference)
n = 11 (number of terms)
Plugging the values into the formula:
Sn = (11/2)(2(10) + (11-1)(8))
= (11/2)(20 + 10(8))
= (11/2)(20 + 80)
= (11/2)(100)
= 550
Therefore, the value of the arithmetic series is 550.
The correct answer is C) 550.

Your 5 neighboring restaurants charge $9.95, $12.95, $8.50, $8.95, and $10.50 for a hamburger special. What is the mean price?
Answer:
$10.17
Step-by-step explanation:
Mean simply is defined as "average", so the average price of a hamburger across five resturaunts is found by adding all of the prices together and then dividing by the number of prices there are.
9.95 + 12.95 + 8.50 + 8.95 + 10.50 = 50.85 dollars, which then you divide by 5, and end up with the solution: $10.17

volume of the tent in cubic feet?
1 square meter is equivalent to 0.0001 square centimeter
72.576 cubic inches. in cubic feet is 0.042 cubic feet
Conversion in math is a way of changing the value of an expression using units.
1) In order to change 1 square meter to square centimeters, we will use the conversion
1m = 0.01cm
Taking the square of both sides
(1m)² = (0.01cm)²
1m² = 0.01cm * 0.01cm
1m² = 0.0001cm²
This shows that 1 square meter is equivalent to 0.0001 square centimeter
2) We are to convert 72.576 cubic inches to cubic feet. Using the conversion factor:
1 cubic inch = 0.000578704 cubic feet
72.576 cubic inches = x
Cross multiply
x = 72.576 * 0.000578704
x = 0.042 cubic feet
