The coordinate of the point P that partitions the segment in the ratio 4 : 1 is 7

The endpoints are given as:

Endpoint 1, A = -5

Endpoint 2, B = 10

The ratio is given as

Ratio, m : n = 4 : 1

The coordinate of the point P that partitions the segment in the ratio 4 : 1 is calculated as:

Point P = Ratio * (B - A) + A

Substitute the known values in the above equation

Point P = 4/5 * (10 + 5) - 5

Evaluate

Point P = 7

Hence, the coordinate of the point P that partitions the segment in the ratio 4 : 1 is 7

Answer:

circumference (c) = 43.96cm

Area (A) = 615.44cm²

Step-by-step explanation:

Here,

Radious (r) = 7 cm

circumference (c) = \(2\pi r\)

                            = 2×3.14×7

                            =43.96cm

Area (A) = \(4\pi r^{2}\)

              = 4×3.14×7²

               =12.56×49

               = 615.44cm²

Answer:

area:153.86m²

circumfrence:43.96m

Step-by-step explanation:

Step-by-step explanation:

y=mx+b

y= -5 x= 10

-5 = 2/5 (10) + b

-5 = 4 + b

b= -9

the equation of aline is y = 2/5(x) -9

or 2x = 5y + 45

The values of the complex expressions are ✓(x - iy) = a - ib and x² + y² =  (a + ib)²(a - ib)²

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

✓(x + iy) = a + ib

Changing the signs, we have

✓(x - iy) = a - ib

Multiply both expressions

This gives

✓(x + iy) * ✓(x - iy) =  (a + ib)(a - ib)

Square both sides

So, we have

(x + iy) * (x - iy) =  (a + ib)²(a - ib)²

This gives

x² + y² =  (a + ib)²(a - ib)²

Hence, the values of ✓(x - iy) is a - ib and x² + y² is  (a + ib)²(a - ib)²

The number itself equals any integer raised to the power of one.

What is Exponent?

The number of times a number has been multiplied by itself is referred to as an exponent. For instance, the expression 2 to the third (written as 23) signifies 2 x 2 x 2 = 8. 23 and 2 x 3 = 6 are not equivalent. Keep in mind that any number is itself when raised to the power of 1.

What is integer?

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. The set of integers is frequently represented in mathematical notation by the boldface Z or blackboard bold mathbb Z.

Any number that is multiplied by one has the same value as the original number, according to the exponent rule.

Take this as an example:

You can write x to the power of 1 as x and 100 to the power of 1 as 100.

Therefore, anything raised to the power of one equals that number.

Answer:

\((f\circ g)(x)= x + 4\)

Step-by-step explanation:

Composite Function

Given f(x) and g(x) as real functions, the composite function \((f\circ g)(x)\) is defined as:

\((f\circ g)(x)=f(g(x))\)

It can be found by substituting g into f.

We are given the functions:

f(x) = -x + 3

g(x) = -x -1

Find

\((f\circ g)(x)=f(g(x))= - (-x -1) + 3\)

Removing parentheses:

\((f\circ g)(x)= x + 1 + 3\)

Simplifying:

\(\mathbf{(f\circ g)(x)= x + 4}\)

The following system of liner equation when converted into equivalent matrix gives us x =2, y = 3, z = -2.

Given that the augmented matrix is [AB] = \(\left[\begin{array}{cccc}1&2&2&4\\0&1&-3&9\\0&0&1&-2\end{array}\right]\)

Since p(A) = p(AB) = 3 = n = The number of variables

The system has unique solution

x + 2y + 2z = 4

y - 3z = 9

z = -2

y = 9 + 3z = 9 + 3(-2) = 3

x = 4-2y -2z

= 4 -2(3) -2(-2)

= 4 - 6 + 4

= 2

Therefore, the solution is x =2, y = 3, z = -2.

The abecedarian idea is to add multiples of one equation to the others in order to exclude a variable and to continue this process until only one variable is left. Once this final variable is determined, its value is substituted back into the other equations in order to estimate the remaining unknowns. This system, characterized by step ‐ by ‐ step elimination of the variables, is called Gaussian elimination.

Answer:

B should be worth more points.

Step-by-step explanation:

Given -  Consider a randomly shuffled deck of ten cards labeled

              {1, 1, 2, 2, 3, 3, 4, 4, 5, 5}, of which game play requires three

               to be drawn.

To find - Which one should be worth more points:

              A getting a pair of matching cards within the three,

              or B getting a set of three cards that can be arranged such

              that the sum of two of them is the value of the third.

Proof -

Given that, three cards has to be drawn.

So, total number of ways the card be drawn = ¹⁰C₃

                                                                      = \(\frac{10!}{3! (10-3)!}\)

                                                                      = \(\frac{10!}{3! 7!}\)

                                                                      = \(\frac{10.9.8.7!}{3! 7!}\)

                                                                      = \(\frac{10.9.8}{3.2.1}\)

                                                                      = 120

⇒¹⁰C₃ = 120

Now,

Given that, A getting a pair of matching cards within the three

Sample space = { (1,1,2), (1,1,3).(1,1,4),(1,1,5);

                            (2,2,1),(2,2,3),(2,2,4),(2,2,5);

                             (3,3,1),(3,3,2),(3,3,4),(3,3,5);

                              (4,4,1),(4,4,2),(4,4,3),(4,4,5);

                              (5,5,1),(5,5,2),(5,5,3),(5,5,4) }

⇒n(A) = 20

Also,

B getting a set of three cards that can be arranged such that the sum of two of them is the value of the third

Sample space = { (1,1,2),(1,2,3),(1,3,4),(1,4,5),(2,2,4),(2,3,5) }

⇒n(B) = 6

Now,

P(A) = \(\frac{20}{120} = \frac{1}{6}\) = 0.167

P(B) = \(\frac{6}{120} = \frac{1}{20}\) = 0.05

We can see that, P(B) < P(A)

⇒B should be worth more points.

The correct option on Hash 1 and Hash 2 is C. Hash 1 is designed to work with small input data, while Hash 2 is optimized for processing large input data.

The main difference between Hash 1 and Hash 2 is the amount of input data they can process. Hash 1 can process input data that is 2 characters long, while Hash 2 can handle input data that is up to 300,000 characters long. This means that Hash 2 is better suited for processing larger datasets than Hash 1.

In terms of which hash function is better suited for different types of data, it depends on the specific application and the characteristics of the data being processed. For example, if the data being hashed is small and of low complexity, Hash 1 may be a good choice due to its speed and simplicity.

Step-by-step explanation:

Let x and (x + 1) be the page numbers Josiah can see

Hint 1: x(x + 1) = 930

⇒ x² + x = 930

⇒ x² + x - 930 = 0

Using quadratic formula,

\(x = \frac{-b\pm\sqrt{b^2 -4ac} }{2a}\)

a = 1, b = 1 and c = -930

\(x = \frac{-1\pm\sqrt{1^2 -4(1)(-930)} }{2(1)}\\\\= \frac{-1\pm\sqrt{1 +3720} }{2}\\\\= \frac{-1\pm\sqrt{3721} }{2}\\\\= \frac{-1\pm61 }{2}\\\)

\(x = \frac{-1-61 }{2}\;\;\;\;or\;\;\;\;x= \frac{-1+61 }{2}\\\\\implies x = \frac{-62 }{2}\;\;\;\;or\;\;\;\;x= \frac{60 }{2}\\\\\implies x = -31\;\;\;\;or\;\;\;\;x= 30\)
