Imagine math Item 994395
Start with the equation 0.2=0 to explain why -4-2 must equal -8.
Drag descriptions and equations to the table to complete the explanation.

Answers

In order to explain why -4 - 2 equals -8, let's start with the equation 0.2 = 0. By analyzing this equation, we can uncover the reason behind this seemingly counterintuitive result.

1. Begin with the equation 0.2 = 0.

2. Subtract 0.2 from both sides of the equation to isolate the variable: 0.2 - 0.2 = 0 - 0.2.

  This simplifies to 0 = -0.2.

3. Observe that the right side of the equation, -0.2, is a negative number.

4. Recall that subtracting a negative number is equivalent to adding its positive counterpart. Therefore, -0.2 is the same as +0.2.

5. Rewrite the equation as 0 = +0.2.

6. Notice that 0 on the left side of the equation is equal to 0 + 0, since any number added to zero remains unchanged.

7. Substitute 0 + 0 for 0 in the equation: 0 + 0 = +0.2.

8. Simplify the equation to 0 = +0.2.

9. Finally, recognize that a positive number cannot equal zero. Hence, the equation 0 = +0.2 is false.

10. As a result, the original equation 0.2 = 0 is invalid.

11. Therefore, the logical consequence is that any subsequent deductions based on this invalid equation would also be incorrect.

12. Consequently, -4 - 2 does not equal -8, as per the explanation derived from the flawed equation.

To summarize, by analyzing the equation 0.2 = 0, we can determine that subsequent deductions based on this equation are incorrect. Hence, -4 - 2 does not equal -8.

Step-by-step explanation:

Factorize polynomials:

Use exponent law:

                   \(\boxed{\bf a^{m*n}=(a^m)^n} \ & \\\\\boxed{\bf a^m * b^m = (a*b)^m}\)

9x²y⁶ = 3²* x² * y³*² = 3² * x² * (y³)² = (3xy³)²

25x⁴y⁸ = 5² * x²*² * y⁴*² = 5² * (x²)² * (y⁴)² = (5x²y⁴)²

Now use the identity:  a² - b² = (a +b) (a -b)

Here, a = 3xy³ & b = 5x²y⁴

9x²y⁶ - 25x⁴y⁸ = 3²x²(y³)² - 5²(x²)² (y⁴)²

Malcolm has $50 gift card to a local car wash and order is the ultimate car wash each visit is $8.95

Answers

The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.

The correct answer choice is option B.

How much cheaper is the car washes Malcolm orders than the car washes Martha's order?

Malcolm's gift card = $50.

Cost Malcolm's car wash per visit = $7

Martha's gift card = $180

Cost Martha's car wash per visit = Difference between gift card balance of first and second visit

= $180 - $160

= $20

How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7

= $13

Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

Triangle XYZ is shown on the coordinate plane.

A triangle on the coordinate plane with vertices X at 0 comma 5, Y at 10 comma 3, and Z at 4 comma negative 1.

If triangle XYZ is translated using the rule (x, y) → (x + 2, y + 3) and then reflected across the x-axis to create triangle X″Y″Z″, what is the location of Z″?

(6, −2)

Answers

The transformation of triangle XYZ vertices at X(0, 5), Y(10, 3), and Z(4, -1), indicates that the coordinate of the point Z'' following a composite transformation of a translation of (x, y) → (x + 2, y + 3), and a reflection across the x-axis, is located at the point (6, -2). The correct option is therefore;

(6, -2)

What is a reflection transformation?

A reflection transformation is a transformation that produces a mirror image of a geometric figure across a line of reflection.

The coordinates of the vertices of the triangle are;

X(0, 5), Y(10, 3), Z(4, -1)

The transformation rule that is used to translate the triangle ΔXYZ (to get ΔX'Y'Z'), can be presented as follows;

(x, y) → (x + 2, y + 3)

The reflection of the translated figure of the triangle (ΔX'Y'Z'), to get ΔX''Y''Z'', is a reflection across the x-axis, therefore, we get;

The coordinates of the point (x, y) following a reflection across the x-axis is the point (x, -y)

Therefore, we get the coordinate of the point (x, y) following the composite transformation is the point (x + 2, -(y + 3))

(x, -y) → (x + 2, -(y + 3))

The coordinates of the point Y(4, -1) following the composite transformation is therefore;

Y(4, -1) → (4 + 2, -(-1 + 3)) = (6, -2)

Andrea placed $1700 in a savings account compounded monthly at 2.5%. What is the value of her account after 8 years?

Answers

Answer:

Step-by-step explanation:

To calculate the value of Andrea's savings account after 8 years, we need to find the balance after compounding the interest for 96 months (8 years x 12 months per year). We can use the formula for compound interest:

A = P * (1 + r/n)^(nt)

where:

A is the balance after t years,

P is the initial balance ($1700),

r is the annual interest rate (2.5%),

n is the number of times interest is compounded in a year (12),

t is the number of years (8).

Converting the interest rate to a decimal and dividing by the number of times compounded per year:

r/n = 2.5% / 12 = 0.021

Plugging in the values into the formula:

A = 1700 * (1 + 0.021)^(12 * 8) = 1700 * (1.021)^96

Calculating the value:

A = 1700 * 2.8412 = 4860.80

So, the value of Andrea's account after 8 years would be $4860.80.

Find the equation of the parabola, the equation of the directrix and the equation of the axis of symmetry

Find the equation of the parabola, the equation of the directrix and the equation of the axis of symmetry

Answers

We know that the focus is at the point F(-5,2); we also know that the directrix of the parabola is eight units to the right of the focus, which means that it passes through the point (3,2) and since it is a vertical line the equation of the directix is:

\(x=3\)

The equation of the axis of symmetry in this case must be horizontal and it is given as:

\(y=2\)

To find p we first need to find the distance between the two points we discussed earlier, then we will divide by two since the distance between the directix and the focus is twice the value of p. The distance between two poitns is given by:

\(d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\)

Plugging the values of the points we have:

\(\begin{gathered} d=\sqrt{\left(-5-3\right)^2+\left(2-2\right)^2} \\ d=\sqrt{\left(-8\right)^2+\left(0\right)^2} \\ d=\sqrt{64+0} \\ d=\sqrt{64} \\ d=8 \end{gathered}\)

Hence the absolute value of p is:

\(\lvert p\rvert=\frac{8}{2}=4\)

Now, since the directix is to the right of the focus this means that the parabola has to open to the left which implies that p has to be negative. Hence:

\(p=-4\)

Once we know p we can find the vertex of the parabola. Since the parabola is horizontal and we know it opens to the right we just need to add the absolute value of p to the x-coordinate of the focus, hence we have:

\(V\left(-1,2\right)\)

Finally we can find the equation of the parabola:

\(\begin{gathered} x=\frac{1}{4\left(-4\right)}\left(y-2\right)^2+\left(-1\right) \\ x=-\frac{1}{16}\left(y-2\right)^2-1 \end{gathered}\)

Therefore, the equation of the parabola is:

\(x=-\frac{1}{16}(y-2)^{2}-1\)

The speed of the plane is equal to 120 mph.

What is speed?

In Mathematics and Geometry, speed is the distance covered by a physical object per unit of time. This ultimately implies that, speed can be measured by using miles per hour (mph).

Mathematically, the speed of any a physical object can be calculated by using this formula;

Speed = distance/time

Time = distance/speed

Let the variable s represent the speed of the plane in miles per hour. Therefore, an equation that models the situation can be written as follows;

240/s = 80/s - 80

80s = 240s - 19200

Log x + 4x³

Answers

I believe the expression you provided is:

(log(x) + 4x^3) / x

To find the discontinuities of this expression, we need to identify any values of x that would cause the expression to be undefined. These values are called the discontinuities.

There are two types of discontinuities to look for:

Removable discontinuities: These occur when a function is undefined at a certain point but can be made continuous by redefining the function at that point.

Non-removable discontinuities: These occur when a function is undefined at a certain point and cannot be made continuous by redefining the function at that point.

To find the discontinuities of the given expression, we need to look for values of x that would make the denominator equal to zero, as this would result in a non-removable discontinuity.

So we solve the equation:

x = 0

This means that x cannot be equal to zero, as it would make the denominator zero and the expression undefined.

Therefore, the only discontinuity of the expression is at x = 0.

Note that there are no removable discontinuities in this expression, as the expression is continuous everywhere except at x = 0.

Answer:  879.20 km²

Step-by-step explanation:

The diameter of the big circle is 2(10) + 18 = 38

divide the diameter by 2 to get the radius (r) = 19

Area (A) = π·r²

             = π(19)²

             = 361π

The diameter of the small circle is 18

divide the diameter by 2 to get the radius (r) = 9

Area (A) = π·r²

             = π(9)²

             = 81π

The area of the shaded region is the difference between the big circle and the small circle.

\(Area_{shaded}=A_{big}-A_{small}\)

                 = 361π - 81π

4x – 1.9 = 22.2
4x – 22.2 = 1.9
4x + 1.9 = 22.2
4x + 22.2 = –1.9
22.2 – 4x = 1.9

Answers

Answer:

4x + 1.9 = 22.2

22.2 - 4x = 1.9

Step-by-step explanation:

Define the variable:

Let x be the cost of one tire patch (in dollars).

Given information:

Number of tire patches purchased = 4Total amount available to spend = $22.20Amount remaining after sale = $1.90

First equation

The cost of 4 tire patches and the amount remaining on the gift card equals the total amount on the gift card:

⇒ 4x + $1.90 = $22.20

⇒ 4x + 1.9 = 22.2

Second equation

The total amount on the gift card less the cost of 4 tire patches equals the amount remaining:

⇒ $22.20 - 4x = $1.90

⇒ 22.2 - 4x = 1.9

Answer:

4x + 1.9 = 22.2

22.2 - 4x = 1.9

2. proved down

3. f(10) = -20 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5

Step-by-step explanation:

Let us explain how to solve the question

∵ f(0) = -20, f(n) = f(n - 1) - 5 for n > 1

→ That means we have an arithmetic sequence with constant

   difference -5 and first term -20

1. → f(1) means we need to find the second term, which equal the

      term - 5

∵ f(1) means n = 1

∴ f(1) = f(1 - 1) - 5

∴ f(1) = f(0) - 5

∵ f(0) = -20

f(1) = -20 - 5 → Proved

2. → f(3) means we need to find the third term, which equal the

   second term - 5

∵ f(3) means n = 3

∴ f(3) = f(3 - 1) - 5

∴ f(3) = f(2) - 5

→ f(2) = f(1) - 5

∵ f(1) = -20 - 5

∴ f(2) = [-20 - 5] - 5 = -20 - 5 - 5

∴ f(3) = [-20 - 5 - 5] - 5

f(3) = -20 - 5 - 5 - 5 → Proved

3. → From 1 and 2 we notice that the number of -5 is equal to n,

      at n = 1 there is one (-5), when n= 3 there are three (-5)

∵ n = 10

∴ There are ten (-5)

∴ f(10) = -20 - 5(10)

f(10) = -20 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 → Proved

If your base pay is 10000 your commission rate is 40% you sell 15 cars and you earn 40000 how much does each car cost

Answers

Answer:  $4,000

Step-by-step explanation:

If the total earnings were $40,000 and the base pay was $10,000, then the commission earned would be $40,000 - $10,000 = $30,000.

Since the commission rate is 40%, we can set up the equation:

40% x Total Sales = Commission Earned

We know that the commission earned is $30,000, and we also know that 15 cars were sold. Therefore, we can solve for the average price of each car:

40% x Total Sales = Commission Earned

40% x (15 x Price per Car) = $30,000

6 x Price per Car = $30,000

Price per Car = $5,000

However, this is just the average price per car. Since the commission is based on the total sales, we need to calculate the actual commission earned on each car:

Commission per Car = 40% x Price per Car

Commission per Car = 40% x $5,000

Commission per Car = $2,000

Therefore, the total earnings of $40,000 divided by the number of cars sold (15) gives the amount earned per car:

Amount earned per Car = Total Earnings / Number of Cars Sold

Amount earned per Car = $40,000 / 15

Amount earned per Car = $4,000

Answers

Answer:

8.9 miles

Step-by-step explanation:

well, you got 2 points with their coordinates on the grid if the city. to make it easy, the origin = point (0,0) is also the center of the city.

the school is 4 miles east = 4 units plus to the right in positive x direction.

and 2 miles south = 2 units down in negative y direction.

so, the point school is (4, -2).

the pool is 8 miles east = 8 units plus to the right in positive x direction.

and it is 6 miles north = 6 units up in positive y direction.

so, the point pool is (8, 6).

now we need to find the distance between both points to see how far they need to travel.

just one remark : this is flawed, as we can usually not make a beeline in a city from one place to another. we have to go along streets. but let's ignore that and just find the air distance.

now, to find the direct distance between 2 points, we need Pythagoras for right-angled triangles

c² = a² + b²

c = the Hypotenuse, the baseline opposite of the 90 degree angle. = the direct distance between the 2 points.

a and b are the sides of a right-angled triangle, which are nothing else than the differences of the x and y coordinates of the 2 points.

the x difference between school and pool is 8-4 = 4.

the y difference between school and pool is 6 - -2 = 6 + 2 = 8.

don't worry, if you did it the other way around and got negative numbers. remember that in the Pythagoras formula everything has to be squared first (and that turns also negative numbers into positive ones).

so, we get

c² = 4² + 8² = 16 + 64 = 80

c (the distance) = sqrt(80)

"sqrt" is the usual abbreviation of "square root".

sqrt(80) ≈ 8.9 miles

Don Swifter earns $9.75 per hour as a clerk. He starts work Monday through Friday morning at 8:00 AM. He takes a one-half hour lunch break every day. If he finishes work at 3:30 PM Monday through Thursday, how late must he work on Friday to have total pay of $360.75 for the week?

Answers

Answer:

He works until 5:30.

Step-by-step explanation:

ok so first, every day don would take a total of 7 hours and 30 minutes on mon-Thurs. If we subtract his lunch from that total it would be 7 hours so next we do 7 hours times 9.75 which is 68.25$. Now that we know how much he makes per day, we times that by 4 since mon-thurs is 4 days. This would be 273$. Now we need to get to 360.75 so we subtract that. This would be 87.75$. Now if a normal day is 68.25$ and friday is 87.75, we find the diffrence which is 19.50. which is also 9.75(an hour) x 2 resulting in 2 hours extra. Therefore, he works 9 hours and 30 minutes on fridays (until 5:30). Thanks for putting in the work to understand and have a nice day!

Don must work approximately 9 additional hours on Friday to have a total pay of $360.75 for the week.

How to determine how late he must work

Don works from 8:00 AM to 3:30 PM Monday through Thursday. Let's calculate his total work hours for these four days:

Total work hours from Monday to Thursday:

(3:30 PM - 8:00 AM) - 0.5 hours (lunch break)

= 7.5 hours - 0.5 hours

= 7 hours (per day)

Total work hours for the week (Monday to Thursday):

4 days x 7 hours/day = 28 hours

Total pay for the week = Hourly rate x Total work hours + Additional hours on Friday

$360.75 = $9.75 x 28 hours + Additional hours on Friday

Additional hours on Friday = ($360.75 - $9.75 x 28) / $9.75

Additional hours on Friday = ($360.75 - $273) / $9.75

Additional hours on Friday = $87.75 / $9.75

Additional hours on Friday ≈ 9 hours (rounded to the nearest hour)
