Answer:

25,132.74 miles

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: [tex]C = 2\pi r[/tex]

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

It is around 25,132.74 miles around.

The length of the rectangle = 2 - (1/3n) +(3/n²).

The formula for the area (taking this exists as a rectangle)

Area = length ⋅ width

where A exists the area of the rectangle

l exists the length of the rectangle and w exists the width of the rectangle.

If Area of the rectangle = length ⋅ width

then length of the rectangle = area/ width

Area = 6n² − n +9​

width = 3n²

Area = length [tex]*[/tex] width

length = area/ width

= (6n²  − n +9)/3n²

= 2 - (1/3n) +(3/n²).

The length of the rectangle = 2 - (1/3n) +(3/n²).

Therefore, the correct answer is option A. 2 - (1/3n) +(3/n²).

Answer:

x = 90°

Step-by-step explanation:

Hello!

The sum of angles on a straight line is 180°.

To find the value of angle x°, we can subtract all the given angles form 180°.

The value of x is 90°.

Step-by-step explanation:

324+x²=729

x²=405===> x=√405===> 9√5

The pythagorean theorem (leg 1)2 + (leg 2)² = (hypotenuse)² the values is about 8.5, -8.5.

The Pythagorean theorem is used to find the length of the sides of a right triangle, not for solving equations like x² = 72.

To solve the equation x² = 72,  to take the square root of both sides to find the value of x:

√(x²) = √(72)

Since the square root of x² is x (the absolute value of x), the equation simplifies to:

x = √(72)

Now, let's find the approximate value of √(72):

√(72) ≈ 8.49

So, the equation becomes:

x≈ 8.49

Now, remember that the absolute value of x is a positive value, so the equation gives two possible solutions for x:

x= 8.49 → x = 8.49

x = -8.49 → x = -8.49

Rounded to the nearest tenth, the solutions are:

x ≈ 8.5 and x ≈ -8.5

The standard equation of the circle is x² + y² + 8x - 9 = 0 if the circle with center at (-1,-4) that passes through the point (-4,0).

According to the question,

The circle with center at (-1,-4) that passes through the point (-4,0).

To find the radius of the circle:

Radius r = √[(-4 - (-1))² + (0- (-4))²]

=√(-4+1)² + (4)²

=√9+16

=√25

=5.

In order to find the standard equation of the circle is

(x - (-4))² + (y - (0))² = (5)²

(x + 4)² + (y )² = 25

x² + 8x + 16 + y² = 25

x² + y² + 8x + 16 = 25

x² + y² + 8x = 25 - 16

x² + y² + 8x = 9

x² + y² + 8x - 9 = 0

Hence, the standard equation of the circle is x² + y² + 8x - 9 = 0.

Step-by-step explanation:

we have 1008=2×2××2×3×3×3

The smallest whole number is 7, by which 1008 should be multiplied so as to get a perfect square.

Now 1008×7=2×2×2×2×3×3×7×7

7056=2×2×3×7

=84

Answer : 7

Answer:

1.   7

2.  square root is 84.

Step-by-step explanation:

First find the prime factors:

1008 =2*2*2*2*3*3*7

There's an even number of 2's and 3's but only one 7, so we multiply by 7

Smallest number = 7.

The square number is 1008 * 7

= 7056.

Its square root is  2*2*3*7 = 84.

You have to complete around 49 assignments everyday to finish in one week.

Step-by-step explanation:

• First, we have to calculate the number of assignments left to do:

Assignments remaining = 419 - 79

                                        = 340

• There are 7 days in a week, which means 340 assignments need to be completed in 7 days.

7 days  ⇒  340 assignments

1 day    ⇒   340 ÷ 7

            =    48.6

            ≅ 49 assignments

∴ You have to complete around 49 assignments everyday to finish in one week.

The bearing to take is 134 degrees and the shortest distance is 14.3 km

The attached diagram represents a labelled version of the ship movement

The angle at Q is

Q = 180 - 155 + 90 + 120 - 90

This gives

Q = 145

The distance PR is calculated as:

PR^2 =PQ^2 + QR^2 - 2 * PQ * QR * cos(Q)

This gives

PR^2 = 9^2 + 6^2 - 2 * 9 * 6 * cos(145)

Evaluate

PR^2 = 205.46

Take the square root

PR = 14.3 km

The angle at P is then calculated as:

QR/sin(P) = PR/sin(Q)

This gives

6/sin(P) = 14.3/sin(145)

Evaluate the quotient

6/sin(P) = 24.93

Make sin(P) the subject

sin(P) = 6/24.93

Divide

sin(P) = 0.2407

Take the arc sin of both sides

P = 14

The bearing is then calculated as:

Bearing = P + 120

This gives

Bearing = 14 + 120

Evaluate

Bearing = 134

Hence, the bearing to take is 134 degrees

In (a), we have

PR = 14.3 km

This represents the shortest distance

Hence, the shortest distance is 14.3 km

Lets assume that the answer is 1000 g.

Then the  3 that make 1800 could be

Answer:

2 face cards

Step-by-step explanation:

By definition, there are 12 face cards (Kings, queens, and jacks) and 36 numbered cards (2's through 10's) in a standard deck of 52 cards.  Aces are not considered face cards (no face on the card).

The ratio of face cards in a full deck is (12/52) or slightly over 23%.

The likelihood of a face card in a hand of 8 cards is:

(8 cards)*(12 face cards/52 cards) = 1.85 cards.  We need to round to the nearest whole card, so the expected number of face cards in a hand of 8 is 2 cards.  

The factored expression of the polynomial is (x - 3)(x + 4)

The polynomial expression is given as;

x^2 + x - 12

Expand the expression

x^2 + 4x - 3x - 12

Factorize the expression

Factor out x + 4
