What two nonnegative real numbers with a sum of 40 have the largest possible product?

Answers

The two non negative real numbers with a sum of 40 have the largest possible product are 20 and 20.

Steps to find Maximum of a function f(x).

Step 1 : Differentiate the function F(x)

Step 2 : Equate f'(x) to zero to find the critical points .

Step 3 : Substitute the critical points in f''(x) , if

f''(x)< 0 them maximum value will be at the critical point.

in the given function

the sum of two non negative real numbers is 40.

Let the numbers be x and y .

So , x+y=40

y=40-x ....(1)

We need to maximize the product i.e. x.y

Substituting the value of y from equation (1) we get

[tex]f(x)=x.y\\ \\ f(x)=x.(40-x)\\ \\ f(x)=40x-x^{2}[/tex]

Step (i) differentiating with respect to x we get

[tex]f'(x)=40-2x[/tex]

Step (ii) Equating f'(x) to 0

[tex]40-2x=0\\ \\ x=20[/tex]

x=20 will be the critical point .

Step (iii) Substituting the critical point in f''(x)

again differentiating with respect to x we get

[tex]f''(x)=-2\\ \\ f''(20)=-2[/tex]

Since -2<0. therefore , x=20 is the point where f(x) is maximum.

Substituting the value of x=20 in equation (1) we get

y=40-x

y=40-20

y=20.

Therefore , the two non negative real numbers with a sum of 40 have the largest possible product are 20 and 20.

The traffic cone is 19 inches tall and has a radius of 5 inches.

(b) Find the surface area.

Answers

The Surface area of a cone is 308.647 sq. inches.

What is the Surface area of cone ?

The area occupied by the surface / boundary of a cone. It is always measured in square units. Stacking many triangles and rotating them around an axis gives the shape of a cone. As it has a flat base, thus it has a total surface area as well as curved surface area.

The surface area of the cone can be given by finding the area of the sector by using the formula,

Area of the sector (in terms of length of arc) = (arc length x radius) / 2 = ((2πr) x l) /2 = πrl.

We are given the height and radius

h = 19 inches

r = 5 inches

The formula for Surface Area is:

Surface Area = πrl

We have to find slant height first:

[tex]l=\sqrt{h^{2}+r^{2} }[/tex]

[tex]l=\sqrt{19^{2}+5^{2} }\\ l=\sqrt{361+25}\\l= \sqrt{386}[/tex]

[tex]l=19.467 inches[/tex]

Now, The Surface Area is:

SA = πrl (π = 3.14)

SA = 3.14 x 5 x 19.467

SA = 308.647 [tex]inches^{2}[/tex]

Hence, The Surface area of a cone is 308.647 sq. inches.

How to solve an equation?

To solve linear equations, utilize the steps that are provided below.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

Answers

The sequence 78,75,72,69,66,63,60, . . . . is arithmetic and the common difference is 3

We can determine that the sequence is arithmetic, because two consecutive terms differ by "d".

To solve this exercise we are going to apply the formula of the arithmetic sequence:

d = aₙ₊₁ - aₙ

Where:

a = first termd = common difference of the sequence

Information about the problem:

Sequence = 78,75,72,69,66,63,60, . . . .d = ?

Calculating the common difference of the sequence (d), we have:

d = aₙ₊₁ - aₙ

Which series has a sum of 5?

Answers

Answer:

The series third has a sum of 5 option (C) is correct because the sequence represents the sum of the infinite terms.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a series shown in the picture.

The geometric sequence is shown in the options.

As we know, in the geometric sequence there is a first term and common difference

In the first sequence:

First term a = 2

Common difference = 2(0.1)/2

Common difference d = 0.1

The sum of the infinite series is:

S = a/(1 - r)

S = 2/(1 - 0.1)

S = 2.22

In the second sequence:

First term a = 15

Common difference = 15(0.3)/15

Common difference d = 0.3

The sum of the infinite series is:

S = a/(1 - r)

S = 15/(1 - 0.3)

S = 21.42

In the third sequence:

First term a = 4

Common difference = 4(0.2)/4

Common difference d = 0.2

The sum of the infinite series is:

S = a/(1 - r)

S = 4/(1 - 0.2)

S = 5

Thus, the series third has a sum of 5 option (C) is correct because the sequence represents the sum of the infinite terms.

exactly the digits in the list. Let a₁ = the (positive) difference between the two numbers. Let an+1 = the sum of the
digits of an for n21. This sequence converges because it is eventually constant. What is the limit?

Answers

Answer: The nth term of the sequence whose integers are between 1 -9 such that there is the permission of repetition but no two consecutive digits must be even is 1.834 x [tex]10^{21}[/tex]

Step-by-step explanation:

Given data,

Two people pair up to create a sequence. Each of them pick five random digits from 1 to 9.

Define Consecutive numbers :

Consecutive numbers are numbers that follow each other in order. They have a difference of 1 between every two numbers. In a set of consecutive numbers, theme an and the median are Equal. If n is a number, then n, n+1, and n+2 would be consecutive numbers Examples. 1, 2, 3, 4, 5.

The numbers that are given:

1, 2, 3, 4, 5, 6, 7, 8, 9 are all consecutive.

Now, suppose a (n) denotes the number of n-digit positive integers as stated in the question, thereby using:

1, 2, 3, 4, 5, 6,7, 8, 9 with the permission of repetition; no two consecutive digits are even.Then, the number of n can be computed as n!

= (9!) x (8!) x (7!) × (6!) × (5!) × (4!) × (3!) × (2!) × (1!)

= 362880 x 40320 x 5040 x 720 x 120 x 24 x 6 x 2 x 1

[tex]n^{th}[/tex] = 1.834 x [tex]10^{21}[/tex]

Therefore,

The nth term of the sequence whose integers are between 1 -9 such that there is the permission of repetition but no two consecutive digits must be even is 1.834 x [tex]10^{21}[/tex].

The value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.

Step-by-step explanation:

It is given that the expression given below is to be simplified using the order of operations;

The given expression is;

=> (3×2)² + 8 = ___² + 8

Now, let us assume that the blank space is 'x' in the above-mentioned question;

Firstly,

We will solve the terms within brackets as per BODMAS rules that is multiplication of both the terms;

=> (3×2)² + 8 = x² + 8

=> 6² + 8 = x² + 8

Now, we will solve the squares of the terms given above;

=> 36 + 8 = x² + 8

Now, we will add the terms as per BODMAS rules;

=> 44 = x² + 8

=> 44 - 8 = x²

Now, we will subtract the terms as per BODMAS rules;

=> 36 = x²

Now, we will square-root both the sides given above;

=> x = √36

=> x = 6

Therefore, the value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.

Answers

Applying the triangle midsegment theorem, the length of BC is: 12 units.

What is the Triangle Midsegment Theorem?

The segment that connects the midpoints of two sides of a triangle is referred to as the midsegment of a triangle.

According to the triangle midsegment theorem, this midsegment is parallel to the third side of the triangle and also has a length that is half of the length of the third side of the triangle.

That is: length of midsegment = 1/2(length of the third side).

Given the following:

DE is a midsegment and is parallel to BC, a third side.

DE = 6 units

Thus, based on the triangle midsegment theorem, DE = 1/2(BC)

Substitute

6 = 1/2(BC)

We can write the following equation to find, first value of m, then the value of n:

65 + 42 + 55 + m = 180 add like terms

162 + m = 180 subtract 162 from both sides
