Answer:

Final price = 1.06x

Step-by-step explanation:

If a city has a 6% general sales tax, then the total cost of any purchase will be the original price of an item plus 6%, as follows:

Final price = (x + 0.06x) = 1.06x

Therefore, the total cost of any purchase is 1.06 where 'x' represents the price of the items without taxes.

Answer:

e =0 or e= -4

Step-by-step explanation:

First we'll equate the given equation with zero then it'll be proper answer and after that it follows like this

By taking e has common

[tex]e(e + 4) = 0 \\ [/tex]

Now,

From this we compare both equation separately and we get

e=0 and e= -4

Note:- If you don't wanna equate the equation with 0 then your answer will be

[tex]e(e + 4)[/tex]

Hope it helps you ...☺

Step-by-step explanation:

Here,

e²+4e

If we take e common we will get,

=e. e+ 4e

= e(e+4)

Which is your final result but you cannot equate it to zero because it is not mentioned in the question. But I think the question is incomplete.

Answer:

$675

$850

$1200

Step-by-step explanation:

Use formula for simple interest:

A = P (1+rt)

where

A = accrued amount (principal + interest) = what we want to find

P = Principal (initial) amount = Given as $500

r = rate of interest = Given as 7% = 0.07

t = time

For 5 years, t = 5

A = 500 [ 1 + 0.07(5) ] = $675

For 10 years, t = 10

A = 500 [ 1 + 0.07(10) ] = $850

For 20 years, t = 20

A = 500 [ 1 + 0.07(20) ] = $1200

Answer:

y+5=-1/2(x+3)

Step-by-step explanation:

as perpendicular,

compare that given eqn with y-y1=m(x-x1),

m1=2

then,

perpendicular case,

m1×m2=-1

m2=-1/2

now,

as the eqn passes through point (-3,-5),

we know,

y-y1=m(x-x1)

then putting value,

y+5=-1/2(x+3)

Answer:

y + 5 = - [tex]\frac{1}{2}[/tex](x + 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line.

y - 4 = 2(x - 6) is in this form with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

Hence the equation passing through (- 3, - 5) is

y - (- 5) = - [tex]\frac{1}2}[/tex] (x - (- 3)), that is

y + 5 = - [tex]\frac{1}{2}[/tex](x + 3) ← equation of perpendicular line

any point that is on the circle will  have a distance of "radius" units, namely 13 units, since the radius is just that.

Final answer:

The point (-5, 12) lies on the circle with a radius of 13 and a center at the origin because it satisfies the equation [tex]x^2 +[/tex] [tex]y^2 = 13^2.[/tex]

Explanation:

The student is asking which point lies on the circle with a center at the origin and a radius of 13. To determine if a point lies on a circle defined by the equation [tex]x^2 + y^2 = r^2,[/tex] where r is the radius, we plug the point's coordinates into the equation and see if they satisfy it.

Let's examine each point:

[tex](-5, 12): (-5)^2 + (12)^2 = 25 + 144 = 169[/tex]

[tex](13, 13): (13)^2 + (13)^2 = 169 + 169 does not equal 169[/tex]

[tex](6, -7): (6)^2 + (-7)^2 = 36 + 49 = 85 does not equal 169[/tex]

Therefore, the point (-5, 12) lies on the circle because it satisfies the equation [tex](-5)^2 + (12)^2 = 13^2.[/tex]

Answer:

5(5 + 2)

Step-by-step explanation:

The distributive property states that If 2 numbers have a common factor you can divide the common factor out. Similarily, if they share a common factor, you can distribute the common factor into each number in the parenthesis.

Find the factors of 25 & 10:

25: 1, 5, 25

10: 1, 2, 5, 10

Note that the largest common factor is 5. Divide 5 from both number:

(25 + 10)/5 = 5(5 + 2)

5(5 + 2) is your answer.

Answer:

Line segment TU is parallel to line segment RS because 32/36 = 40/45.

Step-by-step explanation:

The line segment TU is parallel to the line segment RS because 32 / 36 is equal to 40 / 45.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The converse theorem states that if TU || RS, then the ratio of the corresponding sides will be constant.

32 / 36 = 40 / 45 = 8 / 9 = constant

The line segment TU is parallel to the line segment RS because 32 / 36 is equal to 40 / 45.

Then the correct option is A.

The measure of angle ECB is equal to the degrees that the pentagon rotate

Answer:

A. 12x + 7y = 20

Step-by-step explanation:

Obviously, 12x + 7y cannot both be equivalent to unique [different] quantities.

Option A (12x + 7y = 20) would make the system of linear equations with 12x + 7y = 25 have no solution because the lines would be parallel and never intersect.

Second equation would make a system of linear equations with 12x + 7y = 25 have no solution. A system of linear equations will have no solution if the two lines represented by the equations are parallel, which means they have the same slope but different y-intercepts. Since the first equation is 12x + 7y = 25, we need a second equation with the same coefficients for x and y but a different constant term in order to represent parallel lines.

Option A (12x + 7y = 20) meets the criteria for causing the system to have no solution because it has the same coefficients for x and y as the first equation but a different constant term. This indicates that the lines are parallel and will never intersect, hence no solution exists for this pair of equations.

Answer:

The regression line fits the data well. Problem can be when there is a trend, like exponential growth, but someone still wants to use linear regression. Although in this case it seems to be okay. In other words, the data points can be found under or over the line randomly. In a problematic case is when for example, there are 5 data points next to each other under the line. Usually companies don't make profit when they're first starting.

First  I focused on 3 or more points that were collinear to each other.  Collinear means that when you connect these points, you get a straight line.  These points are at months 1, 2, 3, and 9.  Then of these points, I chose 2 points to find the slope between them.

Point 1 = (1, 0)

Point 2 = (2, 2.5) or  (2, 2500)         because profit is measured in thousands

These are the first two points.

Slope = (2500 - 0) / (2 - 1)

Slope = 2500 / 1

Slope = 2500

Then I plug in the slope and values of point 1 into the slope-intercept form of the line.

y = mx + b

0 = 2500(1) + b

Now we have to Solve for b.

0 = 2500 + b

-2500 = b

Plug in this value of b into the slope intercept form of the equation to get the best fit line.

 y = 2500x - 2500

Answer:

[tex]x> -5.66666[/tex]

x> -5.6 periodical number

Answer:

{x| x > -5.667}

Step-by-step explanation:

We have the following inequality[tex]-1.5x -3 < 5.5[/tex]

We must solve the incus for the variable x

[tex]-1.5x -3 < 5.5[/tex]

Add 3 on both sides of inequality

[tex]-1.5x -3 +3 < 5.5 +3\\\\-1.5x<5.5 +3\\\\-1.5x<8.5[/tex]

Multiply by -1 both sides of the inequality

[tex](-1)*(-1.5)x<8.5*(-1)\\\\1.5x>-8.5[/tex]

Divide between 1.5 both sides of the inequality

[tex]\frac{1.5}{1.5}x>-\frac{8.5}{1.5}\\\\x > -5.667[/tex]

Answer:

81 π / 254.469004941 ft²

Step-by-step explanation:

Area of circle = π × r²

Half the diameter = radius

18 ft ÷ 2 = 9 ft

9 ft = radius

Area of circle = π × 9²

Area of circle = 81π

Area of circle = 81 π / 254.469004941

Area of circle =

To find the area of a circle with a diameter of 18 feet, first find the radius (9 feet), then apply the formula A = πr². The area is approximately 254.47 square feet.

To find the area of a circle, you need to use the formula:

A = πr²

Given the circle's diameter is 18 feet, we first need to find the radius. The radius (r) is half the diameter:

r = D / 2 = 18 ft / 2 = 9 ft

Now, substitute the radius back into the area formula:

A = πr² = π(9 ft)² = π(81 ft²)

Using the approximation π ≈ 3.14159, we get:

A ≈ 3.14159 × 81 ft² ≈ 254.47 ft²

Therefore, the area of the circle is approximately 254.47 square feet.

Answer: B. It can be concluded that the strength training program does not reduce the number of muscular injuries that occur during an athletic event.

Step-by-step explanation: In the question it states the average number of muscular injuries for athletes enrolled in the strength training program is equal to the average number of muscular injuries for athletes not enrolled in the strength training program.

From the coach's report, it can be concluded that the strength training program does not reduce the number of muscular injuries that occur during athletic events. This conclusion is drawn from the experiment's finding that both participants in the training program and those who did not participated had the same average number of injuries.

The student's question concerns the effectiveness of a strength training program in reducing the number of muscular injuries during athletic events. The coach conducted an experiment with 30 athletes, where half participated in a strength training program and the other half did not. After both groups were monitored for five athletic events, it was found that the average number of muscular injuries was the same for both groups. Hence, from the given information, the correct conclusion would be:

It's important to note that this conclusion does not necessarily imply that strength training is ineffective in all contexts, just that in this specific experiment, it did not lead to a reduction in injuries. Further, the conclusion does not indicate that the strength training program increases injuries, which eliminates option C. Meanwhile, option D is also incorrect because the data indicates no reduction in injuries.

For this case we have that by definition of properties logarithm is met:

[tex]log_ {b} (x) -log_ {b} (y) = log_ {b} (\frac {x} {y})[/tex]

So, rewriting the expression we have:

[tex]log (\frac {9x} {2 ^ 3}) = 3\\log (\frac {9x} {8}) = 3[/tex]

By definition of logarithm we have to:

[tex]log_ {b} (x) = y[/tex]is equivalent to[tex]b ^ y = x[/tex]

So:

[tex]10 ^ 3 = \frac {9x} {8}\\9x = 8 * 10 ^ 3\\9x = 8 * 1000\\9x = 8000\\x = \frac {8000} {9}[/tex]

Step-by-step explanation:

Start by finding the number of moles of copper atoms in that 5.2 gram of metallic copper. Look up the relative atomic mass of copper on a modern periodic table.

In other words, the mass of one mole of copper atoms is 63.546 gram.

[tex]M(\mathrm{Cu}) = \rm 63.546\; g\cdot mol^{-1}[/tex].

How many moles of copper atoms in that 5.2 gram sample?

[tex]\displaystyle n = \frac{m}{M} =\rm \frac{5.2\; g}{63.546\; g\cdot mol^{-1}} = 0.0818305\; mol[/tex].

Now, how many atoms is [tex]\rm 0.0818305\; mol[/tex]?

The Avogadro's Number gives the number of particles in one mole:

[tex]N_A \approx \rm 6.022\times 10^{23}\;mol^{-1}[/tex]. (Encyclopedia Britannica)

There are [tex]6.022\times 10^{23}[/tex] particles (a very large number) in one mole. [tex]\rm 0.0818305\; mol[/tex] of copper atoms will thus contain

[tex]N = n\cdot N_A \approx \rm 0.0818305\; mol\times 6.023\times 10^{23}\;mol^{-1} \approx 4.93\times 10^{22}[/tex]

copper atoms.

Step-by-step explanation:

Let's say the circulation for newspaper 1 is X. Then the circulation for newspaper 2 is smaller, by 382, so we can call it (X - 382). It's really 382,000 of course, but we can leave off the extra zeros for now.

Anyway, the total of both would have to be X + (X - 382) = 2492. This simplifies to:

2X - 382 = 2492

If you can solve that equation, you'll have the circulation for newspaper 1, in thousands.

Does this give you a push in the right direction?

The circulation of newspaper 1 is 1437 thousand and the circulation of newspaper 2 is 1055 thousand.

This question requires us to use a system of linear equations to solve for the circulation for each newspaper. Let's denote the circulation of newspaper 1 as x and the circulation of newspaper 2 as y.

We have two pieces of information that help us form two separate equations. The first piece of information is that newspaper 1's circulation is 382 thousand more than newspaper 2's circulation, so we can express this as:

x = y + 382

The second piece of information is that the combined circulation of both newspapers is 2492 thousand. Therefore, we form the equation:

x + y = 2492

We can now replace x in the second equation with the value of x from the first equation (y + 382) to solve for y:

(y + 382) + y = 2492

Solving that, we find that y (the circulation of newspaper 2) is 1055 thousand. Substituting y into the first equation, we can solve for x (the circulation of newspaper 1), which is 1437 thousand.

The midpoint of the line segment with endpoints (-2, 5) and (4, -9) is found using the midpoint formula and is (1, -2).

To find the midpoint of the line segment whose endpoints are (-2, 5) and (4, -9), you use the midpoint formula, which is derived from finding the average of the x-coordinates and the y-coordinates of the endpoints respectively.

The midpoint formula is:

( (x1 + x2) / 2, (y1 + y2) / 2 )

Plugging in our given endpoints (-2, 5) and (4, -9) into the formula, it becomes:

( (-2 + 4) / 2, (5 + (-9)) / 2 )

This simplifies to:

( 2 / 2, -4 / 2 )

And finally:

( 1, -2 )

Therefore, the midpoint of the line segment is at coordinates (1, -2).

Answer:

[tex](x-5)^{2} +(y+4)^{2} =10^{2}[/tex]

Step-by-step explanation:

To calculate the formula of a circle that is not in the center fo the graph, you need two things, the point where the cirlce is centered and any point in the circumference, and with this you can calculate the radius, to calculate the first part you just need the next formula:

[tex](x-x^{c})+(y-y^{c})=r^{2}[/tex]

Where [tex]x^{c}y^{c}[/tex] are the x and y where the center of the circle is, so you just evaluate with the values you are given:

[tex](x-x^{c})+(y-y^{c})=r^{2}[/tex]

[tex](x-(5))+(y-(-4))=r^{2}[/tex]

[tex](x-5)+(y+4)=r^{2}[/tex]

Now that you have the first part, we can calculate the radius, remember taht the radius of any given circumference in the graph is the hypotenuse of the X´s and Y´s that are part of those two points given, so we just calculate it like any hypotenuse:

[tex]c=\sqrt{x^{2}+ y^{2} }[/tex]

To calculate this we would rest to the point in the circumference, the center of the circumference, like this:

[tex]c=\sqrt{(x^{2}-x^{1})^{2}+ (y^{2}-y^{1})^{2} }[/tex]

[tex]c=\sqrt{(-3-5)^{2}+ (2-(-4))^{2} }[/tex]

[tex]c=\sqrt{(-8)^{2}+ (6)^{2} }[/tex]

[tex]c=\sqrt{64+ 36 }[/tex]

[tex]c=\sqrt{100 }[/tex]

[tex]c=10[/tex]

So your radius would be 10, now we just put that into our previous formula:

[tex](x-5)+(y+4)=r^{2}[/tex]

[tex](x-5)+(y+4)=10^{2}[/tex]

So the formula for the circle that is centered at (5,-4) and passes through the point (-3,2) would be:

[tex](x-5)+(y+4)=10^{2}[/tex]

2. bases of a trapezoid

The parallel sides

3. legs of a trapezoid  

The nonparallel sides.  

4. median of a trapezoid  

The segment connecting the midpoints of the legs.  

5. isosceles trapezoid

A trapezoid with legs of the same length.

Answer:

A trapezoid is defined as a quadrilateral with at least one pair of parallel sides, when the trapezoid as equal legs, it's called an isosceles trapezoid.

The bases of a trapezoid are the pair of parallel sides, both of them are called base, the longer one is the major base, and the shorter one is the minor base.

The legs of a trapezoid are the nonparallel sides, because if they were parallel, that wouldn't be a trapezoid, it would be another quadrilateral.

The median of a trapezoid is a segment that connects the midpoints of the legs. Remember that medians are always line that intercept midpoints.

As we said before, an isosceles trapezoid are those which have legs with equal legs. The name isosceles refers to equality.

Therefore, the right matches are

1. Trapezoid: A quadrilateral with at least one pair of parallel sides.  

2. Bases of a trapezoid: The parallel sides.

3. Legs of a trapezoid: The nonparallel sides.  

4. Median of a trapezoid: The segment connecting the midpoints of the legs.  

5. Isosceles trapezoid: A trapezoid with legs of the same length.

Answer:

C

Step-by-step explanation:

B and D are equal. You could call their sum = 2x

a = 25 degrees (Vertically Opposite Angles)

C = 95 degrees. (Vertically Opposite Angles)

The total is 360 degrees. So let's add everything up and see what we get.

a+b+c + 25 + d + 95 = 360 degrees.      Substitute for the known letters.

25 + x + 95 + 25 + x + 95 = 360             Combine like terms on the left

50 + 2x + 95 + 95  = 360                        Combine numbers on the left

240 + 2x = 360                                        Subtract 240 on both sides

240 - 240 + 2x = 360 - 240                    Combine

2x = 120                                                    Divide by 2

x = 60

b = 60

a = 25

a + b =60 + 25 = 85
