Each side of the regular hexagon has a length of approximately 0.759 inches.

What is hexagon?

The closed polygonal shape of a regular hexagon has six equal sides and six equal angles. Any regular polygon has equal sides and angles on all sides.

We know that the area of a regular hexagon can be expressed as:

A = (3√3/2) s²

where A is the area of the hexagon and s is the length of each side of the hexagon.

In this case, we are given that the area of the hexagon is 55.2 square inches, so we can set up the following equation:

55.2 = (3√3/2) s²

To solve for s, we need to first solve for the height of one of the triangles, which is given as 4 inches. Since the hexagon is regular, each of the 6 triangles has the same height, so we can use the height to find the length of each side of the hexagon.

The height of a regular hexagon can be expressed as:

h = √3/2 s

where h is the height of each triangle and s is the length of each side of the hexagon.

In this case, we are given that the height of one of the triangles is 4 inches, so we can set up the following equation:

4 = √3/2 s

Solving for s, we get:

s = 8/√3

Now we can substitute this value of s into the equation for the area of the hexagon to solve for s:

55.2 = (3√3/2) (8/√3)²

55.2 = (3√3/2) (64/3)

55.2 = 32√3

s = √(55.2/32√3)

s = √(55.2/96)

s = √0.575

s ≈ 0.759 inches

Therefore, each side of the regular hexagon has a length of approximately 0.759 inches.

The constant expression as in options is:

E. 12.23154687854

4. 1st order differential equation is the equation in which there is differentiation done once.

\(y'\) or \(\dfrac{dy}{dx}\) are used to represent it.

So, correct option is D. y' - 8x - 6 = 0

5. A 2nd order differential equation is the equation in which there is differentiation done once.

\(y''\) or \(\dfrac{d^2y}{dx^2}\) are used to represent it.

So, correct option is H. y" = 8

6. An ordinary differential equation (1st order)

Same as answer to part 4.

\(y'\) or \(\dfrac{dy}{dx}\) are used to represent it.

So, correct option is D. y' - 8x - 6 = 0

7. A partial differential equation is an equation that contains a term represented as:

\(\dfrac{\partial y}{\partial x}\)

but there is no such term given here, so no option matches.

8. An integration equation:

The correct options are F and G.

F. \(100 y = \int(8x + 6)dx\)

G. \(\int dz = \int 8xdx + \int 8dy\)

Inequalities help us to compare two unequal expressions. The inequality that model this situation is 1c + 2k ≤ 10. The correct option is C.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

Let c represents the number of carrots and k represents the number of leeks.

Given that At the store, carrots are marked at $1.00 per pound, and leeks are marked at $2.00 per pound. Therefore, the total cost can be written as,

1c + 2k

Also, it is given that Emily wants to buy carrots and leeks for a stew, but she only has $10.00 with her. Therefore, she must spend $10 or less than that.

Thus, the inequality can be written as,

1c + 2k ≤ 10

The graph of the given inequality can be made as shown below.

Hence, the inequality that model this situation is 1c + 2k ≤ 10.

Answer:

im pretty sure it 1641 square miles

Answer:

A. 72°

D. 144°

E. 216°

Step-by-step explanation:

are you tempted to calculate the internal angles ?

that is, I guess, the trap set by your teacher here, and it would be the wrong approach.

nevertheless, quickly just as a reminder :

the sum of all internal angles in a polygon is

(n - 2)×180°

n being the number of sides.

in our case that is

(5 - 2)×180 = 3×180 = 540°

so, each internal angle is 540/5 = 108°.

but we are not turning at an edge or vertex. no, we are turning the pentagon around is central point.

we are running each vertex along a circle arc. the center of that circle being P.

after every 1/5 of the circle arc there is a vertex of the pentagon.

and whenever we rotate one vertex on top of the next one, we carry the pentagon visually onto itself.

so, instead of a full circle rotation we need only 1/5 of that :

360 / 5 = 72°

and with every additional 1/5 of the circle arc (or 72°) we get it again.

that means at

72°

144°

216°

288°

360°

the pentagon carries onto itself.

therefore, A, D and E are correct.

Answer:

Sweet Treats Bakery is ordering 14,364 kilograms of sugar this time.

Step-by-step explanation:

To find the amount of sugar that Sweet Treats Bakery is ordering this time, we need to add 52% more sugar to the previous amount of 9,450 kilograms.

We can start by finding what 52% of 9,450 is:

52% of 9,450 = 0.52 * 9,450 = 4,914

This means that Sweet Treats Bakery is ordering an additional 4,914 kilograms of sugar.

To find the total amount of sugar that the bakery is ordering, we can add this amount to the previous amount of 9,450:

total amount of sugar = previous amount + additional amount

total amount of sugar = 9,450 + 4,914

total amount of sugar = 14,364

Therefore, Sweet Treats Bakery is ordering 14,364 kilograms of sugar this time.

Answer:

  38 million

Step-by-step explanation:

You want the current value of Algeria's population according to the model P = 38(1+r)^t. (P is in millions.)

We generally assume that the "initial value" of a function is the y-intercept of its graph, the value when the independent variable is zero.

When the function is predicting into the future, we usually take the "current value" and the "initial value" to be the same thing, unless the description of the model tells you otherwise.

Here, that is ...

  P = 38(1 +r)^0 = 38·1 = 38 . . . . . millions

The current population is 38 million.

Step-by-step explanation:

The best first step would be to multiply the second equation by -2

then you would have the following

\(\ \ \ \ \ \ 4x - 5y = 2 \\-2*(2x)+ (-2)*y = (-2)*3\)

and when you multiply it is easy to eliminate because you will get

   \(4x - 5y = 2 \\-4x -2y = 6\)

The measure of angle ADM is 45.0°, as the intercepted arc AD is congruent to arc CD.

To find the measure of angle ADM, we need to consider that angle ADM is an inscribed angle and its measure is half the measure of the intercepted arc AD.

Given that the measure of arc CD equals the measure of arc DA, it means that these arcs are congruent.

Therefore, the intercepted arcs AD and CD have equal measures.

Since angle ADM is an inscribed angle intercepting arc AD, the measure of angle ADM is half the measure of arc AD.

Therefore, the measure of angle ADM is 45.0°, as the intercepted arc AD is congruent to arc CD.

The graph of g(x) is obtained from the graph of f(x) by the following transformations:

- A horizontal stretch by a factor of 9. This is because the graph of g(x) is 9 times wider than the graph of f(x).

- A vertical translation down by 2 units. This is because the graph of g(x) is 2 units lower than the graph of f(x).

In other words, to obtain the graph of g(x) from the graph of f(x), we stretch the graph horizontally by a factor of 9 and then translate it down by 2 units.

Here is a more detailed explanation of the transformations:

- Horizontal stretch by a factor of 9: To stretch the graph horizontally by a factor of 9, we multiply all of the x-coordinates by 9. This means that every point on the graph of f(x) will be moved 9 units to the right on the graph of g(x).

- Vertical translation down by 2 units: To translate the graph down by 2 units, we subtract 2 from all of the y-coordinates. This means that every point on the graph of f(x) will be moved 2 units down on the graph of g(x).

Explanation:

Let,

These equations are valid because segment AP bisects the angle CAB, i.e. it splits it into two equal pieces. Similarly, segment BP bisects angle ABC.

Then we can say,

Let's focus on triangle CAB. The three interior angles add to 180 degrees. This is true of any triangle.

(angleCAB)+(angleCBA)+(angleACB) = 180

(2x) + (2y) + (44) = 180

2x+2y+44 = 180

2(x+y+22) = 180

x+y+22 = 180/2

x+y+22 = 90

x+y = 90-22

x+y = 68

Normally we would try to isolate one variable, but I'll stop here. We'll use this later in the next section.

--------------------

Now focus your attention on triangle PAB.

The three interior angles add to 180.

(anglePAB)+(angleABP)+(angleAPB) = 180

(x)+(y)+(z) = 180

x+y+z = 180

(x+y)+z = 180

68+z = 180 .... replace "x+y" with 68

z = 180-68

z = 112 degrees is the measure of angle APB.
