The geometric mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

Answer:

It has to start on 5 and then go to 0, or else not all of the numbers will go in the knight move pattern.  

We have 5034927618 and 5038167294, plus their opposites (the same number backwards). So only 4 numbers can be formed.

Step-by-step explanation:

It's gonna be an irrational number because the length of the hypotenuse is 6.40312....... cm

[tex] {4}^{2} + {5}^{2} = {41}^{2} [/tex]

[tex] \sqrt{41} = 6.403124237[/tex]

An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).

Answer:

If the legs are equal to 4 cm and 5 cm, respectively we can rewrite the equation 42+52=c2 -> 16+25=41=c^2 so then, c= the square root of 41, which is an irrational number.

Answer:

The first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:

[tex]-3, 9, -27, 81, -243, 729[/tex]

Step-by-step explanation:

Given the sequence

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

Here [tex]n[/tex] represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]\:f\left(1\right)=\left(-3\right)^1[/tex]

[tex]f\left(1\right)=-3[/tex]

Thus, the first term is -3.

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]\:f\left(2\right)=\left(-3\right)^2[/tex]

[tex]\:f\left(2\right)=9[/tex]

Thus, the 2nd term is 9.

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(3\right)=\left(-3\right)^3[/tex]

[tex]f\left(3\right)=-27[/tex]

Thus, the 3rd term is -27.

Determining the 4th term

substitute n = 4 in the sequence to determine the 4th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(4\right)=\left(-3\right)^4[/tex]

[tex]f\left(4\right)=81[/tex]

Thus, the 4th term is 81.

Determining the 5th term

substitute n = 5 in the sequence to determine the 5th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(5\right)=\left(-3\right)^5[/tex]

[tex]f\left(5\right)=-243[/tex]

Thus, the 5th term is -243.

Determining the 6th term

substitute n = 6 in the sequence to determine the 6th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(6\right)=\left(-3\right)^6[/tex]

[tex]f\left(6\right)=729[/tex]

Thus, the 6th term is 729

Therefore, the first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:

[tex]-3, 9, -27, 81, -243, 729[/tex]

The act of factoring is to reduce numbers down to their prime number.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

A prime number is a positive integer having exactly two factors that are 1 and the number itself. Any number that does not follow this is termed a composite number.

For example:

Let the number 2310, then the factor of the number 2310 will be

2310 = 2 × 3 × 5 × 7 × 11

Where, 2, 3, 5, 7, and 11 are the prime numbers.

Answer: 4.8x+3

Step-by-step explanation:

The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.

As per the given data:

The width of the screen = x cm

Height of the screen = 1.9 times the width = 1.9x

Dimensions of the phone are given in the diagram.

The area of the screen = height × width

= 1.9x × x = 1.9x² cm²

The area of the phone = (1.9x + 3)(x + 1)

= 1.9x² + 1.9x + 3x + 3

= 1.9x² + 4.9x + 3 cm²

Area of the phone not occupied by screen:

= area of the phone - area of the screen

= 1.9x² + 4.9x + 3 - 1.9x²

= 4.9x + 3 cm²

Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

Step-by-step explanation:

Step 1: Find out how many pens he bought

12 pens per pack

Charles bought 60 packs

60 packs x 12 pens = 720 pens

Step 2: Find out how much Charles spent

2.80 per pack

Charles bought 60 packs

60 x 2.80 = 168 pounds

Step 3: Find out how many pens Charles sold

Charles sold 2/3 of his pens

2/3 x 720 = 480

Step 4: Find out how manypens he sold

Charles sold the pens for 40p

40p x 480 = 19200p

Step 5: Convert pences to pounds

19200p = 192 pounds

Step 6: Find the profit

192 - 168 = 24 pounds

Answer:

New power = 88 Kw (Approx.)

Step-by-step explanation:

Given:

P = a(v³)

Old power p = 700 Kw

Old wind speed v = 12 m/s

Find:

New power when v = 6m/s

Computation:

P = a(v³)

700 = a(12³)

a = 0.4050 m²

New power = a(v³)

New power = (0.4050)(6³)

New power = 87.48

New power = 88 Kw (Approx.)
