Step-by-step explanation:

An inequality that describes a possible length in yards of the rectangular parking lot is L < 6.

Mathematically, the area of a rectangle can be calculated by using this formula:

A = LW

Where:

Since the city wants the width of the parking lot to be 5 yards and the area of the rectangular parking lot to be more than 30 square yards, an inequality that models a possible lengths of the rectangular parking is giving by;

A > LW

30 > 5L

Dividing both sides of the inequality by 5, we have:

6 > L

L < 6

The slope of the table is 2.

What is slope?

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). The ratio of how much y grows as x grows by a certain amount is known as the slope of a line. A line's slope, or the amount by which y rises as x rises, indicates how steep a line is. The slope is constant (the same) along the line.

Here using given table we can find slope by taking any two points then,

[tex](x_1,y_1)=(6,0) and (x_2,y_2)=(4,-4)[/tex]

Now using slope formula m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> m = [tex]\frac{-4-0}{4-6}[/tex]

=> m = [tex]\frac{-4}{-2}[/tex]

Answer:

The volume of sphere N is 400cm3/8 = 50cm3

Step-by-step explanation:

The volume of a sphere is given by the formula: V = 4/3 * π * r^3

where V is the volume, π is pi (approximately 3.14), and r is the radius of the sphere.

Given that the volume of sphere M is 400cm3 and the radius of sphere N is half the radius of sphere M, we can write an equation to find the volume of sphere N:

Vm = 4/3 * π * rm^3 = 400cm3

We know that radius of sphere N is half of sphere M so

rn = rm/2

So the volume of sphere N can be found by substituting the value of radius of sphere N in the sphere volume formula:

Vn = 4/3 * π * (rm/2)^3

Vn = 4/3 * π * (rm^3)/8

Vn = (Vm)/8

So, the volume of sphere N is 1/8th of the volume of sphere M, which is 400cm3.

The volume of sphere N is 400cm3/8 = 50cm3

Answer: The distance of the ship from the lighthouse is 546.4 feet.

Step-by-step explanation:

What is the angle of elevation?

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

The beacon light is 126 feet high, the angle of elevation to the beacon is 13° and the distance from the lighthouse to the ship = x

These from a right-angled triangle,

from trigonometry

tan 13 = 126/x

making x the subject of the equation we have

x tan 13 = 126

x = 126/tan 13

but tan 13 = 0.2308

x = 126/0.2308

x = 546.4 feet

In conclusion, the ship's distance from the lighthouse is 546.4 feet.

To find the mass of the lamina, we need to integrate the density function over region D. The density function is given by? (x, y) = 7ky, where k is a constant. The region D is bounded by y = [tex](1 ? x^2)[/tex]  and y = 0, and the limits of integration are [tex]0 < = y < = (1 - x^2)[/tex] .

So, the mass of the lamina is:

[tex]m = ∫∫?(x, y) dx dy = ∫∫ 7ky dx dy\\= 7k ∫∫ y dx dy = 7k * ∫ (1 - x^2) dy dx\\= 7k * ∫(0 to 1 - x^2) y dy\\= 7k * (1/2 * ∫(0 to 1 - x^2) y^2 dy)\\= 7k * (1/2 * [y^3/3] evaluated at y = (1-x^2) and y=0)\\= 7k * (1/2 * [((1-x^2)^3/3] - 0))= 7k * (1/2 * (1/3 - x^6))[/tex]

To find the center of mass (x bar, y bar) of the lamina, we need to find the x and y coordinates of the center of mass.

The x-coordinate is given by

[tex](x bar) = 1/m * ∫∫ x ?(x, y) dx dy = 1/m * ∫∫ x * 7ky dx dy \\= 7k * ∫ (x * y) dx dy\\= 7k * (x * 1/2 * ∫(0 to 1 - x^2) y^2 dy)\\= 7k * (x * 1/2 * [y^3/3] evaluated at y = (1-x^2) and y=0)\\= 7k * (x * (1/2 * (1/3 - x^6))\\The y-coordinate is given by\\(y bar) = 1/m * ∫∫ y ?(x, y) dx dy = 1/m * ∫∫ y * 7ky dx dy= 7k * ∫ (y^2) dx dy\\= 7k * (1/3 * ∫(0 to 1 - x^2) y^3 dy)\\= 7k * (1/3 * [y^4/4] evaluated at y = (1-x^2) and y=0)\\= 7k * (1/3 * (1/4 - x^6/2))[/tex]

So, x + (-30/x)= 4

x² - 30 = 4x

x² -4x -30 = 0

Solving the Quadratic Equation

x= (4 ±√4² - 4(1)(-30) / 2)

x= (4 ± √136)/ 2

x= (4 ± 11.66)/2

x= (4+ 11.66)/2  or x= (4- 11.66)/2

7(1) = 7

5 - 7 = -2

x = 1 is true and that means y = -2 (because g(x) also means y

x = 5

1. g(x) = 5 - 7x

This can also be written as g(5) = 5 - 7x
