the value of the given function f(g(1)) is 2 , fog is an even function

A function f is even if the equation f(x)=f(x) f (x) = f ( x) holds for every x and x in the domain of f. An even function has a graph that is geometrically symmetric with respect to the y-axis, which means that even after reflection about the y-axis, the graph does not change.

f is even (given)

∴f(−x)=f(x)

g is odd (given)

∴g(−x)=−g(x)

So,

According to question,

fog=f[g(x)]=f(y)             Let [g(x)]=y

and also,

fog=f[g(−x)]        ∵g(x) is odd

       =f[−g(x)]

       =f(−y)

       =f(y)

⇒fog(x)=fog(−x)

∴fog is an even function

[tex]4x^2 - 12x - 12x + 36[/tex]

Step-by-step explanation:

To find the maximum and minimum values of the objective function subject to the given constraints, we can use the method of linear programming.

Step 1: Convert the inequality constraints into equations by replacing the inequality signs with equality signs and adding slack or surplus variables as necessary to get the equations in the form of standard linear equations.

So the equations become:

2x + 3y + s1 = 6 (where s1 is a non-negative slack variable)

2x - 3y + s2 = 6 (where s2 is a non-negative slack variable)

y + s3 = 2 (where s3 is a non-negative slack variable)

Step 2: Write the objective function F as a linear function of the variables x and y.

F = 4x - y

Step 3: Formulate the linear programming problem in the standard form as follows:

Minimize or maximize F = 4x - y, subject to:

2x + 3y + s1 = 6

2x - 3y + s2 = 6

y + s3 = 2

where x, y, s1, s2, and s3 are non-negative variables.

Step 4: Solve the system of equations to find the feasible region.

We can solve the system of equations using matrix methods to obtain:

x = 3, y = 0, s1 = 0, s2 = 0, s3 = 2

x = 0, y = 2, s1 = 0, s2 = -6, s3 = 0

x = 0, y = 0, s1 = 6, s2 = 6, s3 = 2

x = 2, y = 0, s1 = 0, s2 = 2, s3 = 2/3

x = 1.5, y = 0.5, s1 = 0, s2 = 1.5, s3 = 1.5

x = 0, y = 2/3, s1 = 2, s2 = -2/3, s3 = 0

Step 5: Evaluate the objective function at each corner point to determine the maximum and minimum values.

F(3, 0) = 4(3) - 0 = 12

F(0, 2) = 4(0) - 2 = -2

F(0, 0) = 4(0) - 0 = 0

F(2, 0) = 4(2) - 0 = 8

F(1.5, 0.5) = 4(1.5) - 0.5 = 5.5

F(0, 2/3) = 4(0) - (2/3) = -2/3

Therefore, the maximum value of the objective function is 12, which occurs at the corner point (3, 0), and the minimum value is -2, which occurs at the corner point (0, 2).

Answer:

substitute the value of y

y=15-x

3(15-x)=5x+3

45-3x=5x+3

-3x-5x=3-45

Answer:

x = 5 , ML = 18

Step-by-step explanation:

the midsegment NP of the trapezoid is half the sum of the bases, that is

NP = [tex]\frac{JK+ML}{2}[/tex]

25 = [tex]\frac{4x-2+6x+2}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

50 = 10x ( divide both sides by 10 )

5 = x

Then

ML = 4x - 2 = 4(5) - 2 = 20 - 2 = 18

The remaining customer advance at the end of 2025 is $16,592,000.

To determine the amount of customer advance remaining at the end of 2025, we need to subtract the amount collected in 2025 from the customer advances balance at the end of 2024:

Customer advances balance at the end of 2024 = $12,518,000

Amount collected in 2025 = $30,256,000

Customer advances recognized in income in 2025 = $26,182,000

Customer advances balance at the end of 2025 = Customer advances balance at the end of 2024 + Amount collected in 2025 - Customer advances recognized in income in 2025

Customer advances balance at the end of 2025 = $12,518,000 + $30,256,000 - $26,182,000

If h(x) = 5 4f(x) , where f(1) = 5 and f '(1) = 4, then h'(1) = 20.

To find h'(1), we need to use the chain rule of differentiation, which states that if h(x) = f(g(x)), then h'(x) = f'(g(x)) * g'(x).

In this case, we have h(x) = 5/4 * f(x), where f(1) = 5 and f'(1) = 4. Therefore, g(x) = x, f(x) = 5, and h(x) = 5/4 * 5 = 6.25.

To find h'(1), we need to evaluate f'(g(1)) and g'(1), then multiply them together. Since g(x) = x, we have g'(1) = 1.

Since f'(x) = 4, we have f'(g(1)) = f'(1) = 4. Therefore, h'(1) = f'(g(1)) * g'(1) = 4 * 1 = 4. However, we are looking for h'(1), so we need to multiply this by the coefficient of f(x), which is 5/4. Therefore, h'(1) = 5/4 * 4 * 1 = 20.

a. q-p = 11-3 = 8, which is an even number. b. p+q = 3+11 = 14, which is an even number.

In mathematics, a prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other words, a prime number is a number that can only be divided evenly by 1 and itself.

There are various methods for finding prime numbers, such as the Sieve of Eratosthenes, which is a simple algorithm for generating all prime numbers up to a given limit. However, as the numbers get larger, it becomes increasingly difficult to find prime numbers, and there is no known formula for generating all prime numbers.

a. One possible example is:

p = 3

q = 11

Here, q-p = 11-3 = 8, which is an even number. However, if we add 1 to it, we get 9, which is odd but not prime (since it is divisible by 3).

b. One possible example is:

p = 3

q = 11

Here, p+q = 3+11 = 14, which is an even number. However, if we add 1 to it, we get 15, which is odd but not prime (since it is divisible by 3 and 5).

If the diameter of the tennis ball is 7cm. then the exact volume of the cylinder is approximately 807.96 cubic centimeters.

The volume of a cylinder is calculated using the formula

              V = πr²h,

      where r is the radius and h is the height.

In this case, the radius of the cylinder is equal to the radius of a tennis ball which is half its diameter or 3.5cm.

The height of the cylinder is equal to the diameter of three tennis balls or 21cm. Plugging these values into the formula gives us:

              V = π * 3.5² * 21

The approximated value of x in the equation given as 6^(2x+1)=8^(x+1) is 0.192

From the question, the equation is given as

6^(2x+1)=8^(x+1)

Take the logarithm of both sides of the equation

So, we have

(2x + 1)log(6) = (x + 1)log(8)

Divide both sides of the equation by log(6)

So, we have

2x + 1 = (x + 1) * 1.161

So, we have

2x + 1 = 1.161x + 1.161

Evaluating the like terms, we get

0.839x = 0.161

Divide both sides by 0.839

Answer:

36

Step-by-step explanation:

(2 x 10)+(2 x 8) = 36

The total area is 36 cm squared.

Answer:

To find the area of the isosceles trapezoid, we can use the formula:

Area = ((upper base + lower base) / 2) x height

First, we need to find the height of the trapezoid. We can use the Pythagorean theorem to find the height, since the legs of the trapezoid form a right triangle with the height as the hypotenuse.

Using the Pythagorean theorem:

height^2 = leg^2 - ((lower base - upper base) / 2)^2

= 5^2 - ((16 - 8) / 2)^2

= 25 - 4^2

= 9

height = 3 cm

Now that we have the height, we can use the area formula:

Area = ((8 + 16) / 2) x 3

= 12 x 3

= 36 cm^2

Therefore, the area of the isosceles trapezoid is 36 square centimeters.

To solve the quadratic function -3x² + 5x + 9 = 0, the formula that should be used is Option C: x = (-5 ± √133) / -6.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The quadratic formula is used to solve quadratic equations in the form of ax² + bx + c = 0, where a, b, and c are constants.

To use the quadratic formula to solve the equation -3x² + 5x + 9 = 0, we need to identify the values of a, b, and c.

In this case, a = -3, b = 5, and c = 9.

Therefore, we can use these values to plug into the quadratic formula -

x = (-b ± √(b² - 4ac)) / 2a

So the answer that can be used to find the solutions to the equation using the quadratic formula is -

x = (-5 ± √(5² - 4 × (-3) × 9)) / 2 × (-3)

Solving this equation we get -

x = (-5 ± √(25 + 108)) / -6

x = (-5 ± √133) / -6

Therefore, the solution is obtained by the equation x = (-5 ± √133) / -6.
