Answer:

The total area of the farm land is  2520 sq. m

Step-by-step explanation:

Let us assume the total area of the farm land  = P sq. m

Now, two thirds of the area of a farm land was covered by wheat fields.

So, the area covered in Wheat field = [tex]\frac{2}{3}  \times P = (\frac{2}{3})P[/tex]

The area left which is not covered in wheat

= Total land - Land covered  in Wheat  

= [tex]P - (\frac{2}{3}) P =  (\frac{1}{3})P[/tex]

Also, the half of the remaining land is covered by pound.

So, the area covered in pound  = [tex]\frac{1}{2}  \times (\frac{P}{3} )  = (\frac{P}{6} )[/tex]

The other half is empty garden.

⇒The area empty garden  =   [tex]\frac{1}{2}  \times (\frac{P}{3} )  = (\frac{P}{6} )[/tex]

Also, the area of the garden = 420 sq. m

⇒[tex](\frac{P}{6})  =  420\\\implies  P = 6 \times 420 =  2520[/tex]

or, P  = 2520 sq. m

Hence, the total area of the farm land is  2520 sq. m

Answer:

[tex]y=2\text{cos}((\frac{2\pi}{3})t)[/tex]

Step-by-step explanation:

We have been given that an object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. We are asked to find the cosine function that can be used to model the height of the object.

We know that standard form of cosine function is [tex]y = A\cdot \text{cos}(Bt-C)+D[/tex], where,

|A| = Amplitude,

Period = [tex]\frac{2\pi}{|B|}[/tex],

C = Phase shift,

D = Vertical shift.

Since distance between maximum and minimum is 4, therefore, amplitude will be half of it, that is, [tex]A = 2[/tex].

Since objects gets back to its maximum value in every 3 seconds, therefore, period of the function is 3 seconds. We know that period is given by [tex]\frac{2\pi}{|B|}[/tex], therefore, we can write [tex]\frac{2\pi}{|B|}=3[/tex], therefore, [tex]B = \frac{2\pi}{3}[/tex].

We haven't been given any information about phase and mid-line, we can assume the values of C and D to be zero .

Therefore, our function required function would be [tex]y=2\text{cos}((\frac{2\pi}{3})t)[/tex].

Two years ago, Sally had 5,000 dogs in her dog shelter. Now she has 24,575 dogs. The rate of change is 391.5 % increase

Solution:

Given that Two years ago, Sally had 5,000 dogs in her dog shelter

Now she has 24,575 dogs

To find: rate of change

A rate of change is a rate that describes how one quantity changes in relation to another quantity

[tex]\text {rate of change }=\frac{\text { new value }-\text {original value}}{\text {original value}} \times 100[/tex]

[tex]\begin{array}{l}{\text { rate of change }=\frac{24,575-5000}{5000} \times 100} \\\\ {\text { rate of change }=\frac{19575}{5000} \times 100=391.5}\end{array}[/tex]

x = 3 or x = 4

Step-by-step explanation:

Given

x² + 12 = 7x ( subtract 7x from both sides )

x² - 7x + 12 = 0 ← in standard form

(x - 3)(x - 4) = 0 ← in factored form

Equate each factor to zero ( zero product property ) and solve for x

x - 3 = 0 ⇒ x = 3

x - 4 = 0 ⇒ x = 4

Answer: 2 and 7/12

Step-by-step explanation: To subtract 4 - 1 and 5/12, first subtract the fractions. Since 4 has no fraction, imagine the fraction 0/12.

Notice however that we can't subtract 0/12 - 5/12.

So, let's rewrite 4 and 0/12 as 3 + 1 and 0/12 or 3 + 12/12 by changing 1 and 0/12 into an improper fraction.

Now we have 3 and 12/12 - 1 and 5/12.

Now we can subtract our fractions 12/12 - 5/12 and we get 7/12. Next we subtract our whole numbers 4 - 1 to get 3.

So 5 - 1 and 5/12 is 2 and 7/12.

b + a = 376 .........…...... eqn(1)

2. Second sentence.

If the bike is worth 7 times more than the accessories.

Equation;

b = 7a

3. Substitute b into eqn 1

7a + a = 376

a = 376/8

a= 47

b= 7a = 7× 47 = 329

Therefore The bike cost $ 329

Answer:

2nd Option i.e M is the correct name of a plane.

Step-by-step explanation:

A plane is a flat surface which extends out in all direction without ending.

Just imagine the plane like taking a piece of paper except all the sides continue out forever and ever without ending.

For example, we have a plane as shown in attached figure a below. It extends out forever and ever without an ending. You must remember that planes do have infinite amount of points and lines on them.

Here, we identify point G, as shown in figure a. We can also indicate the line as well on this plane, and can put some points on this line, like V, D and Q.

There are several ways to name a plane. One way, we need at least three or more pints to name a plane. The only rule is that, those points you identify on the plane, cannot make a straight line. If they do, you cannot label the plane as those points.

So, lets pick three points that cannot make a straight line on a plane. As D, V and G cannot make a straight line as shown in figure a. So, DVG is one of the correct names of this plane. Since, order of points do not matter. So, DGQ can also be one of the correct names of this plane. Please remember, VDQ can not be the name of this plane, as these points make a straight line.

Now, planes could just be named with just a letter. Take this letter M written on a plane, as shown in figure a, but it doesn't have a point attach to it, meaning this letter is identifying the plane. Hence, we could just name this plane as just plane m.

So, from this entire discussion, and some rules and regulations necessary to identify a plane, we can safely say that 2nd Option i.e. M is the correct name of a plane.

Answer:

x = 6 ± i√23

Step-by-step explanation:

x² − 12x + 59 = 0

Use quadratic formula.

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-12) ± √((-12)² − 4(1)(59)) ] / 2(1)

x = [ 12 ± √(144 − 236) ] / 2

x = (12 ± √-92) / 2

x = (12 ± 2i√23) / 2

x = 6 ± i√23

The values of x are 1.2 or 10.8.

The given equation is x²-12x+59=0.

We need to find the value of x.

The standard form of a quadratic equation is ax²+bx+c=0.

Use quadratic formula [tex]x=\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

Now, a=1, b=-12 and c=59

[tex]x=\frac{12\pm\sqrt{(-12)^{2} -4\times 1\times 59} }{2\times 1}[/tex]

⇒x=1.2 or 10.8

Therefore, the values of x are 1.2 or 10.8.

She sold 98 small cups and 57 large cups

Step-by-step explanation:

Ashley had a summer lemonade stand

We need to find how many cups of each type she sold

Assume that Ashley sold x small cups and y large cups of lemonade

∵ Ashley sold x small cups of lemonade

∵ She sold y large cups of lemonade

∵ Ashley sold a total of 155 cups

∴ x + y = 155 ⇒ (1)

∵ The price of the small cup = $1.25

∵ The price of the large cup = $2.5

∵ The price of the all cups = $265

- Multiply x by 1.25 and y by 2.5 and add the two products,

  then equate the sum by 265

∴ 1.25x + 2.5y = 265 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -2.5 to eliminate y

∵ -2.5x - 2.5 y = -387.5 ⇒ (3)

- Add equations (2) and (3)

∴ -1.25x = -122.5

- Divide both sides by -1.25

∴ x = 98

- Substitute the value of x in equation (1) to find y

∵ 98 + y = 155

- Subtract 98 from both sides

∴ y = 57

She sold 98 small cups and 57 large cups

American airlines made a total money of $ 4263

Solution:

Given that,

Cost of 1 first class ticket = $ 53

Cost of 1 coach ticket = $ 21

There were 139 passengers total

30% of the passengers composed of the first class, Which means 30 % of 139 are first class

Number of first class passengers = 30 % of 139

[tex]\rightarrow \frac{30}{100} \times 139 = 41.7[/tex]

Thus approximately 42 passengers are from first class

Number of coach class passengers = 139 - 42 = 97

So we have,

Number of first class passengers = 42

Number of coach class passengers = 97

To find: Total money made by American airlines

We can frame a equation as:

total money = (Number of first class passengers x Cost of 1 first class ticket) + (Number of coach class passengers x Cost of 1 coach ticket)

[tex]\text{ total money } = 42 \times 53 + 97 \times 21\\\\\text{ total money } = 2226 + 2037 = 4263[/tex]

Thus american airlines made a total money of $ 4263

The correct answer is D. All natural numbers are integers, as natural numbers are part of the larger set of integers which includes all whole numbers both positive, negative, and zero.

Out of the options given, the true statement is: D. All natural numbers are integers. This is because natural numbers include all positive counting numbers from 1 upwards, which are also part of the integers set that includes all whole numbers both positive and negative, as well as zero.

Option A is incorrect because not all real numbers are rational. Real numbers include both rational numbers (which can be written as fractions of integers) and irrational numbers (which can't be expressed as fractions of integers).

Option B is incorrect because while all whole numbers are natural numbers, the set of whole numbers also includes 0 which is not considered a natural number.

Option C is incorrect since all integers are indeed whole numbers, but not all whole numbers are integers as integers also include negative numbers.

In addition to the answer, the commutative property of addition, which states that A+B=B+A was mentioned. This property holds true for the addition of ordinary numbers, such as 2 + 3 is the same as 3 + 2.

g(10) = 3(10)+4 = 30+4 = 34

answer: 34

Answer: g(10) = 34

Explanation: In this problem we are given the function g(x) = 3x + 4 and we are asked to find g(10).

In other words, if we put an x into our function, we get a 3x + 4 out so we are really being asked what happens if we put a 10 into the function.

Well if we put a 10 into the function, that's g(10) = and we get a 3(10) + 4 out.

Now all we have to do is simplify on the right side. 3 x 10 is 30 and 30 + 4 is 34. So g(10) = 34.

Answer:

B

A

Step-by-step explanation:

[tex]f(x) = \left \{ \left \begin{matrix}5x-6,\ x<4\\x^{2}-2,\ 4 \leq x \leq 6\\4x+10,\ x>6 \end{matrix} \right } \right[/tex]

To find f'(x), take the derivative within each interval.  Clearly, it's 5 in the first one, 2x in the second one, and 4 in the third one.  But we need to determine if the derivative exists at the ends of each interval.

For a derivative to exist at a point x=a, the function must be continuous (f(a⁻) = f(a⁺)), and smooth (f'(a⁻) = f'(a⁺)).

Let's look at x=4.  On the left side:

f(4⁻) = 14, f'(4⁻) = 5

On the right side:

f(4⁺) = 14, f'(4⁺) = 8

So the function is continuous, but not smooth.  Therefore, the derivative doesn't exist there.

Let's try again with x=6.  On the left side:

f(6) = 34, f'(6) = 12

On the right side:

f(6⁺) = 34, f'(6⁺) = 4

Again, the function is continuous, but not smooth, so the derivative doesn't exist there either.

Therefore, f'(x) is:

[tex]f'(x) = \left \{ \left \begin{matrix}5,\ x<4\\2x,\ 4<x<6\\4,\ x>6 \end{matrix} \right } \right\ Domain:\ All\ real\ numbers,\ x\neq 4,6[/tex]

When we graph f(x) = (4x² − 1) / (x² − 9), we see f(x) has a horizontal tangent line at x=0.

The midpoint of a segment can be found by averaging the x-coordinates and y-coordinates of the endpoints, with the formula M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2) representing the midpoint's coordinates.

Explanation:

The formula for finding the midpoint of a segment involves calculating the average of the x-coordinates and the average of the y-coordinates of the two endpoints of the segment.

If we have two points, A(x₁, y₁) and B(x₂, y₂), the coordinates of the midpoint M will be calculated as follows:

Thus, the coordinates of the midpoint M will be (Mx, My). This formula is essential when dealing with problems involving geometry, coordinate systems, or finding the center point between two given locations on a line segment.
