Answer: THIRD OPTION.

Step-by-step explanation:

Given the trapezoid in the figure, you know the coordinates of  two points:

(0,c) and (a,b)

You can observe that the point (a,b) and the point P have the same x-coordinate, because both points are "a" units from the origin.

Then, the x-coordinate of P is:

[tex]x=a[/tex]

Now, in order to find the y-coordinate of the point P, you need to remember that when the line touches the x-axis, the value of "y" is equal to zero. Therefore, the y-coordinates of the point P is:

[tex]y=0[/tex]

Then the answer is:

[tex](a,0)[/tex]

Answer:

After 2.9 years the town's tax status will change

The towns tax status change within the next 3 years

Step-by-step explanation:

The question below is

Will the towns tax status change within the next 3 years ?

Let

y -----> the population of a small town

t ----> the number of years

we have a exponential function of the form

[tex]y=a(b)^{t}[/tex]

where

a is the initial value

b is the base

In this problem

[tex]a=9,400\ people[/tex]

[tex]b=100\%-14.3\%=85.7\%=85.7/100=0.857[/tex]

substitute

[tex]y=9,400(0.857)^{t}[/tex]

Remember that

The town's tax status will change once the population is below 6,000 people

so

The inequality that represent this situation is

[tex]9,400(0.857)^{t}< 6,000[/tex]    

Solve for t

[tex](0.857)^{t}< 6,000/9,400[/tex]

Apply log both sides

[tex](t)log(0.857)< log(6,000/9,400)[/tex]

[tex]-0.067t< -0.1950[/tex]

Multiply by -1 both sides

[tex]0.067t > 0.1950[/tex]

[tex]t > 2.9\ years[/tex]

so

After 2.9 years the town's tax status will change

therefore

The answer is

Yes, the towns tax status change within the next 3 years

the town's tax status will change a little over 7 years from the current time, assuming the rate of population decline remains constant.

To find out after how many years the population of the town would decrease to below 6,000 people, we start with the current population and apply the annual exponential decrease. The population decreases at a rate of 14.3% each year, which means the remaining population each year is 85.7% (100% - 14.3%) of the previous year. Starting with a population of 9,400 people, we need to solve for t in the inequality 9400  × (0.857)^t < 6000. We take the natural logarithm of both sides to solve for t:

ln(9400 × (0.857)^t) < ln(6000)

t × ln(0.857) < ln(6000) - ln(9400)

t > (ln(6000)-ln(9400)) / ln(0.857)

Using a calculator, we find that:

t > 7.17

Therefore, the town's tax status will change a little over 7 years from the current time, assuming the rate of population decline remains constant.

The difficulty between theorems and proofs in geometry is subjective. Theorems are proven true statements, while proofs are the logical processes used to establish the truth of theorems. Students may find one harder than the other depending on their individual abilities and understanding.

In the study of geometry, students often ask which are harder: theorems or proofs. To address this, it's important to understand the nature of both. A theorem is a statement that has been proven to be true through a logical sequence of statements, starting from agreed-upon assumptions, known as axioms. The Pythagorean Theorem, for instance, states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. This theorem provides a consistent and reliable outcome as long as the arithmetic is carried out correctly.

On the other hand, a proof is the process by which a theorem is shown to be true. Proofs involve a series of logical deductions from accepted principles and previously proven theorems. They are essentially the 'work' or argument that establishes the truth of a theorem. In any proof, each step must logically follow from the previous ones based on established geometric postulates and existing theorems. Therefore, a proof can be viewed as a bridge that connects the basic assumptions of geometry to the theorem being proven.

Whether theorems or proofs are harder is subjective and depends on the student's strengths. Some students find memorizing theorems challenging, while others may struggle with the logical sequence and creativity required to craft proofs. Nonetheless, the study of geometry contributes valuable reasoning skills and knowledge that connects fundamental truths of mathematics to practical applications in the real world, like engineering and physics.

Answer:

a=3

b=12

c=13

Step-by-step explanation:

(see attached)

The value of 'a' is 3, 'b' is 12, and 'c' is 13 and this can be determined by using the arithmetic operations.

Given :

Expression -  [tex]\dfrac{2^5\times 8^4}{16}=\dfrac{2^5\times (2^a)^4}{2^4}=\dfrac{2^5\times 2^b}{2^4}=2^c[/tex]

The value of a, b, and c can be determined by following the below calculations:

[tex]\dfrac{2^5\times 8^4}{16}=\dfrac{2^5\times (2^a)^4}{2^4}[/tex]

Further, simplify the above expression:

[tex]\dfrac{2^5\times (2^3)^4}{2^5}=\dfrac{2^5\times (2^a)^{4}}{2^4}[/tex]

the above equation holds good when the value of 'a' is 3.

[tex]\dfrac{2^5\times 8^4}{2^4}=\dfrac{2^5\times 2^b}{2^4}[/tex]

Further, simplify the above expression:

[tex]\dfrac{2^5\times 2^{12}}{2^5}=\dfrac{2^5\times 2^b}{2^4}[/tex]

the above equation holds good when the value of 'b' is 12.

[tex]\dfrac{2^5\times 2^{12}}{2^5}=2^c[/tex]

Further, simplify the above expression.

[tex]\dfrac{2^{17}}{2^4}=2^c[/tex]

[tex]2^{13}=2^c[/tex]

the above equation holds good when the value of 'c' is 13.

Everywhere you see x in the equation replace it with 1 like so...

3(1) + y = 5

3 + y = 5

Finish isolating y. To do this first subtract 3 to both sides (what you do on one side you must do to the other). Since 3 is being added, subtraction (the opposite of addition) will cancel 3 out (make it zero) from the left side and bring it over to the right side.

3 - 3 + y = 5 - 3

0 + y = 2

When x is 1 then y is 2

Check:

3(1) + 2 = 5

3 + 2 = 5

Answer: 14.9

I have to write this in order to have enough characters.

7.45 divided by 0.5 equals 14.9. This is calculated by converting the divisor 0.5 to a whole number and doing the same operation on the dividend, then performing the division.

Dividing Decimals

To find what 7.45 divided by 0.5 is, one approach is to think of 0.5 as one-half, so you are essentially finding out how many halves there are in 7.45. Another way to approach this is to manipulate the numbers to make the division easier. Since 0.5 is equivalent to the fraction 1/2, dividing by 0.5 is the same as multiplying by 2 (which is the reciprocal of 0.5). Here are the steps to perform the division:

Therefore, 7.45 divided by 0.5 equals 14.9.

Answer: 72and 108

Step-by-step explanation: that is the correct answer don’t be a fool

Answer:

Step-by-step explanation:

You need an x value to determine what number to multiply that will give you three numbers that are in the ratio of 3:1:4

Let the number = x

Set the equation up as 3x + x + 4x = 500

3x + x + 4x = 500           Combine the left

8x = 500                         Divide both sides by 8

x = 500/8                        Divide by 8.  

x = 62.5

So 3x = 3*62.5 = 187.5

1x       = 1 * 62.5 =  62.5

4x      = 4 * 62.5 = 250    The total should be 500

Answer:

{187.50, 62.50, 250}

Step-by-step explanation:

Add up the numbers in the ratio:  Add up 3, 1 and 4.  We get 8.

Then we divide up 500 into eight parts, each 62.5.

The ratio we are to follow is 3:1:4.

3 parts of 62.5 each comes out to 187.5;

1 part of 62.5 each comes out to      62.5; and

4 parts of 62.5 each comes out to 250.

If we have done this correctly, these 3 results add up to 500:

187.50

 62.50

250

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

   500

So, 500 divided up in the ratio 3:1:4 is {187.50, 62.50, 250}

Answer:

The slope is [tex]m=\frac{5}{4}[/tex]   or  [tex]m=1.25[/tex]

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

[tex]A(9,7)\ B(5,2)[/tex]

Substitute the values

[tex]m=\frac{2-7}{5-9}[/tex]

[tex]m=\frac{-5}{-4}[/tex]

[tex]m=\frac{5}{4}=1.25[/tex]

3. [tex]-6[/tex].

4. [tex]2\frac{1}{3}[/tex].

5. [tex]2[/tex].

6.  [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

1. The required line passes through [tex](3,0),(-11,-15)[/tex]. The slope of the line joining the points  [tex](x_1,y_1),(x_2,y_2)[/tex] is given by the formula,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] or [tex]m=\frac{y_1-y_2}{x_1-x_2}[/tex]

Either of them yields the same result.

Substitute [tex]x_1=3,y_1=0,x_2=-11,y_2=-15[/tex] into the first formula to get,

[tex]m=\frac{-15-0}{-11-3}[/tex] [tex]\implies m=\frac{-15}{-14}=\frac{15}{14}[/tex]

You can write this as a mixed number to obtain:

[tex]\implies m=1\frac{1}{14}[/tex]

2. The given line passes through [tex](4,-8),(4,13)[/tex].

Observe that the first coordinates are the same for both points. This implies that, the line is vertical.

The slope of all vertical lines are undefined.

3. The average rate of change of the function [tex]y=f(x)[/tex] on the interval [tex][a,b]\:\:or\:\:a\le x\le b[/tex] is given by:

[tex]ARC=\frac{f(b)-f(a)}{b-a}[/tex].

The given function is [tex]f(x)=x^2-4x[/tex]

[tex]f(-2)=(-2)^2-4(-2)=12[/tex]

[tex]f(4)=(4)^2-4(4)=0[/tex]

[tex]ARC=\frac{f(4)-f(-2)}{4--2}[/tex].

[tex]ARC=\frac{0-12}{6}=-6[/tex].

4. The given function is [tex]f(x)=2^x-1[/tex]

[tex]f(0)=2^0-1=0[/tex]

[tex]f(3)=2^3-1=7[/tex]

[tex]ARC=\frac{f(3)-f(0)}{3-0}[/tex].

[tex]ARC=\frac{7-0}{3}=2\frac{1}{3}[/tex].

5. From the graph

[tex]f(3)=7,f(0)=1[/tex]

[tex]ARC=\frac{f(3)-f(0)}{3-0}[/tex].

[tex]ARC=\frac{7-1}{3}[/tex].

[tex]ARC=\frac{6}{3}=2[/tex].

6. The given equation is :

[tex]2y-7x=-4[/tex]

Add [tex]7x[/tex] to both sides.

[tex]2y=7x-4[/tex]

Divide through by 2.

[tex]y=\frac{7}{2}x-2[/tex]

Compare this function to [tex]y=mx+b[/tex]

The slope is [tex]m=\frac{7}{2}[/tex]

Final answer:

The cost for Mrs. Beusse to buy 100 personalized pencils is $405.00.

Explanation:

According to the chart, the cost of pencils depends on the number of pencils being purchased. For 1-20 pencils, the cost is $5.35 each. For 21-40 pencils, the cost is $4.70 each. For 41-60 pencils, the cost is $4.05 each. Since Mrs. Beusse needs to buy 100 personalized pencils, we need to determine which price range this falls into. 100 pencils falls within the range of 81-100, so the cost per pencil will be $4.05.

Therefore, the total cost for 100 personalized pencils will be $4.05 x 100 = $405.00.

Answer:

51 in² is the area of the shape.

Step-by-step explanation:

Note that there is a triangle, as well as a Parallelogram.

First, solve for the measurement for the Parallelogram. The Parallelogram has sides that measure 6 in. & 7 in. respectively.

Note the measurement of the left length, which is 13. The right length is 7. To solve for the length of the triangle, subtract the two:

13 - 7 = 6

The triangle length is 6.

To solve for the triangle width, subtract the part from the total:

6 - 3 = 3

The triangle width is 3.

Note that the area of the triangle is found using the formula: Area = 1/2base x height (or length x width). Plug in the corresponding numbers to the corresponding variable.

A = 1/2(3)(6)

A = (3)(3)

A = 9

The triangle's area is 9 in².

Solve for the area of the parallelogram:

6 x 7 = 42

The parallelogram's area = 42 in².

Add the two measurements together:

42 + 9 = 51

51 in² is the area of the shape.

~

The above composite shape can be divided into :

●  A Rectangle with Length 7 in. and Width 6 in.

●  A Right angled Triangle with base 3 in. and height 6 in.

Let us first find the Area of Rectangle :

We know that - Area of a Rectangle is given by : Length × Width

[tex]:\implies[/tex]  Area of Rectangle = (7 × 6) in²

[tex]:\implies[/tex]  Area of Rectangle = 42 in²

Now, Let us find the Area of Right angled Triangle :

[tex]\mathsf{We\;know\;that - Area\;of\;a\;Triangle\;is\;given\;by : \dfrac{1}{2} \times base \times height}[/tex]

[tex]\implies \mathsf{Area\;of\;Right\;angled\;Triangle = \dfrac{1}{2} \times 3 \times 6\;(in^2)}[/tex]

[tex]:\implies[/tex]  Area of Right angled Triangle = (3 × 3) in²

[tex]:\implies[/tex]  Area of Right angled Triangle = 9 in²

Area of the Composite shape :

●  Area of Rectangle + Area of Right angled Triangle

[tex]:\implies[/tex]  Area of the Composite shape = (42 + 9) in²

[tex]:\implies[/tex]  Area of the Composite shape = 51 in²

Step-by-step explanation:

Answer:

1. k(x) = (3g + 5h)(x) = -24x+40

2. k(x) = (h - g)(x)  = 0

3. k(x) = (g + h)(x) = -6x+10

4. k(x) = (5g + 3h)(x) = -24x+40

5. k(x) = (3h - 5g)(x) = 6x-10

6. k(x) = (5h - 3g)(x) = 10-6x

Step-by-step explanation:

Given

h(x) = 5 - 3x

and

g(x) = -3 x + 5

1. k(x) = (3g + 5h)(x)

3*g(x) = 3(-3 x + 5)

=> -9x+15

5*h(x) = 5(5 - 3x)

=>25-15x

(3g + 5h)(x)=3*g(x)+5*h(x)

= -9x+15+25-15x

=-9x-15x+15+25

=-24x+40

2. k(x) = (h - g)(x)

(h - g)(x) = h(x) - g(x)

= 5 - 3x -(-3 x + 5)

=5-3x+3x-5

= 0

3. k(x) = (g + h)(x)

(g+h)x = g(x) + h(x)

= -3 x + 5 + 5 - 3x

= -6x+10

4. k(x) = (5g + 3h)(x)

5*g(x) = 5(-3 x + 5)

=-15x+25

3*h(x) = 3(5 - 3x)

=15-9x

(5g + 3h)(x) = 5*g(x) + 3*h(x)

= -15x+25+15-9x

= -15x-9x+25+15

=-24x+40

5. k(x) = (3h - 5g)(x)

(3h - 5g)(x) = 3*h(x)-5*g(x)

=15-9x-(-15x+25)

=15-9x+15x-25

=-9x+15x+15-25

=6x-10

6. k(x) = (5h - 3g)(x)

5*h(x)-3*g(x) = 25-15x - (-9x+15)

= 25-15x+9x-15

= 25-15-15x+9x

=10-6x

Answer:

1. k(x) = (5g + 3h)(x) ---------------- 5. k(x)=40-5(3^x)-9x

2. k(x) = (3h - 5g)(x) ---------------- 6. k(x)=5(3^x)-9x-10

3. k(x) = (3g + 5h)(x) ---------------- 1. k(x)=40-3^x+1-15x

4. k(x) = (5h - 3g)(x) ----------------- 3. k(x)=10+3^x+1-15x

5. k(x) = (h - g)(x) ----------------- 2. k(x)=3^x-3x

6. k(x) = (g + h)(x) ----------------- 4. k(x)=10-3^x-3x

We find the determinant of a matrix by the method below. If we have a matrix:

[tex]\left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]

The determinant is [tex]ad-bc[/tex]

Now, using cramer's rule, we find x-value by the formula:

[tex]x=\frac{D_x}{D}[/tex]

Where D is the determinant of the original problem and [tex]D_x[/tex] is the determinant of the x-value matrix. How do we get those?

To get original matrix and thus D, we set up the matrix as the coefficients of x and y (s) of both the equations and to get matrix of x-value and thus [tex]D_x[/tex], we replace the x values of the matrix with the numbers in the right hand side of the 2 equations. We show this below:

To get D:

[tex]\left[\begin{array}{cc}3&4\\1&-6\end{array}\right] \\D=(3)(-6)-(1)(4)=-18-4=-22[/tex]

To get [tex]D_x[/tex]:

[tex]\left[\begin{array}{cc}12&4\\-18&-6\end{array}\right] \\D_x=(12)(-6)-(-18)(4)=0[/tex]

Putting into the formula, we get:

[tex]x=\frac{D_x}{D}=\frac{0}{-22}=0[/tex]

Thus, the value of x is 0

Answer:

The solution of the equation f (x) = g (x) is the same as the coordinates of the intersection.

Exaple in the attachment.

f(x) = g(x) → x = -2, y = -1 or x = -1 and y = 0 or x = 1 and y = 2.

Step-by-step explanation:

y = x - 2

x + y = 12

Substitute the first expression for y into the second equation.

x + (x - 2) = 12

2x - 2 = 12

2x = 14

x = 7

Now plug into either equation to find y.

y = 7 - 2

y = 5

So the solution is (7, 5).
