The function at its maximum value will be at point (9,2) and its value is 51 which can be derived keeping in mind the constraints that have been given.

The maximum value of any kind of a function is the place where the said function reaches its highest point, or vertex, on a graph. If your kind of quadratic equation has something as a negative of a term, it will also have a maximum value.

There are a bit of three ways to find that maximum, depending on which form of a quadratic function you have got.

here, we have,

Herein we can find the closed region ABC from the three equations or constraints given

and can mark the points as

A = (2,2)

B = (5, 2)

C = (9, 2)

if we put up the values of the points, we get

at (9, 2) ,

z=5x+3y

 =45+6

  =51 that is the maximum value amongst the three.

Thus, the maximum point of the function can be calculated as (9,2)

How do you extract out the maximum or minimum value of a function?

We will at first set out the first derivative of the function to absolute zero and then solve for x to get the exact critical point.

If we then take the second derivative or f’’(x), there in we can find out whether this point will be a maximum or minimum. If the second derivative is seen as positive, it will be a minimum value

What is the maximum value of a function called?

The maximum or minimum value that is calculated over the entire function is called an “Absolute” or “Global” maximum or minimum of the function.

There is presence of only one global maximum (and only one global minimum) but there can be several that is more than one local maximum or minimum

Answer:

In Fig. 12.35, if ATB = 82°, then the angles of ABC would be A = 82°, B = 98°, and C = 180°. This can be determined by using the fact that the sum of the angles in a triangle is 180°.

Step-by-step explanation:

Step-by-step explanation:

The equivalent expression in the form of a product is:

(8x) * (4x + 6)

The measure of angle 4 is 90 degrees

From the question, we have the following parameters that can be used in our computation:

The rectangle

Also, we have

<5 = 12x -3

<6 = 10x + 9

Angles 5 and 6 add up to 90

So, we have

12x - 3 + 10x + 9 = 90

Evaluate the like terms

22x = 84

So, we have

x = 3.82

The angles in a triangle add up to 180

So, we have

<4 + 12 * 3.82 - 3 + 10 * 3.82 + 9 = 180

Evaluate

<4 = 90

Hence, the measure o this angle is 90 degrees

The amount of compound remaining from a 84-ounce sample after seven weeks is 4.32 ounces.

Given a half-life of 5 days and a sample of 84 ounces, the exponential decay function can be represented as:

A(t) = 84 * (1/2)^(t/5)

Where A(t) represents the amount of the compound remaining after t days.

To find the amount of compound remaining after 7 weeks

7 weeks * 7 days/week = 49 days,

we can substitute t = 49 into the function:

A(49) = 84 * (1/2)^(49/5)

A(49) = 84 * (1/2)^9.8

A(49) ≈ 4.32 ounces

Answer:

9.818 years after 2008

Step-by-step explanation:

Y_A = 0.35 * X + 9.6

Y_B = 0.9 * X + 6.5

Equal in year X = (Y_B - Y_A) / (0.35 - 0.9) = (6.5 - 9.6) / (-0.55) = 9.818 years after 2008

X = 9.818 + 2008 = 2018.818

Y_A = 0.35 * (2018 - 2008) + 9.6 = 14.3 billion

Y_B = 0.9 * (2018 - 2008) + 6.5 = 15.3 billion

Step-by-step explanation: Division by zero is considered an invalid operation in mathematics because there is no number that can be multiplied by zero to produce the original number. In other words, there is no single valid answer to dividing by zero. Example: You have 0 cookies and you want to share them among 9 friends. There's no way to share, since you don't have cookies haha!

Answer:

Step-by-step explanation:

An expression without a value is referred to as being undefined; it has an indeterminant form. When a number is divided by zero, it usually has no specified meaning. Mathematically, we can't divide by zero because the result is an equation we can't compute.

The statement that will not produce a triangle is side lengths of 5.5 ft, 11 ft, and 5.5 ft, the correct option is C.

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

[tex](a+b) > c\\(b+c) > a\\(c+a) > b[/tex]

X2 + 7x + 10 = 0 has roots -5 and -2, the answer.

x2 + 7x + 10 = 0 is a mathematical equation.

x2 + 5x + 2x + 10 = 0 [dividing the middle term] is another way to express the aforementioned equation.

After factoring 2 from the second term of the expression, 2x + 10, and x from the first term of the expression, (x2 + 5x), the expression may be broken down into its constituent parts.

We obtain the factorized equation as follows: x (x + 5) + 2 (x + 5) = 0.

Now we can calculate (x + 2) (x + 5) = 0 by utilizing the distributive property.

The combined area of the square and rectangle is 3x² + 3x - 3.

The expression 2x² + 6x - 4 represents the area of a square.  The area of a rectangle is represented by x² - 3x + 1.  The combined area of the square and the rectangle is the sum of the area of the square and the area of the rectangle.

Therefore,

area of the square = 2x² + 6x - 4

area of the rectangle = x² - 3x + 1

Let's find the combined area as follows:

combine area of the square and rectangle = 2x² + 6x - 4 + x² - 3x + 1

combine area of the square and rectangle = 2x² + x² + 6x - 3x - 4 + 1

Answer:

To solve the expression [(4r²t)³]², you need to follow the order of operations (PEMDAS):

Calculate the expression inside the outermost parenthesis first: (4r²t)³ = (4 * r^2 * t)^3, where r and t are variables.

Raise the result to the power of 3: (4 * r^2 * t)^3 = 64 * r^6 * t^3.

Raise the result to the power of 2: (64 * r^6 * t^3)^2 = 4096 * r^12 * t^6.

So, [(4r²t)³]² = 4096 * r^12 * t^6.

1/2, on the other hand, represents half of the whole unit, so it is twice as much as 1/6.

To visualize this, you can think of a ruler divided into 6 equal parts. 1/6 would represent 1 mark on the ruler, while 1/2 would represent 3 marks. To have the same length as 1/2, you need to add up 3 marks, or 3 copies of 1/6.

The predicted interval for the given function is, f(x) ≥ 0 over the interval [-1,1]. So Option C is correct

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

The ordered pairs of the given function

It can be observed from the values of f(x) with respect to x, that the function reaches zero at x = -1, then then reach up to 5 at x = 0 and then again reaches zero at x = 1
