Mary Lou Mason's total taxes on her purchase would be $1.37.

Taxes are mandatory payments to the government that are used to fund public services such as infrastructure, education, and health care. Taxes can be direct, such as income taxes, or indirect, such as sales taxes.

Mary Lou Mason's total purchase was $19.14.

To calculate the total taxes for her purchase, we can use the following formula:

Tax = (State Sales Tax %) x (Total Purchase) + (County Tax %) x (Total Purchase)

Therefore, the total taxes for Mary Lou Mason's purchase would be:

Tax = (6.5%) x ($19.14) + (1.5%) x ($19.14)

Tax = (0.065 x 19.14) + (0.015 x 19.14)

Tax = 1.24 + 0.13

Tax = $1.37

Mary Lou Mason's total taxes on her purchase would be $1.37.

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Hence, the y value is 16.25 if x equals 2. To determine the equivalent values of y, you can similarly change the values of x in the equation.

Your example is an equation since an equation that's any statement with an equal's sign. The usage of equations in mathematical expressions is widespread because mathematicians adore equal signs. An equation is a collection of guidelines for producing a specific outcome.

You appear to have given an equation. Assuming you want an explanation or a condensed version of an equation, it's provided below:

The equation is in the form of exponential function, where "x" is the exponent and "7" is the base. The equation has three terms: "1/4×7ˣ," "2," and "2." The first term is the exponential part of the equation, and the other two terms are constants.

By first evaluating the exponential term and then changing mathematical value of "x" in the solution, you can make the equation simpler. For instance, the equation becomes: if "x" is 2.

Y = 1/4×7² + 2 + 2

Simplifying this expression, we get:

Y = 1/4×49 + 4

Y = 12.25 + 4

Y = 16.25

Therefore, if x is equal to 2, the value of y is 16.25. You can similarly substitute different values of x into the equation to find the corresponding values of y.

The image point of (3,-4) after a translation left 2 units and up 5 units is (1,1).

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

We are given that;

Point= (3,-4)

Now,

To find the image point of a translation, we can use the following rule:

To translate a point left or right, add or subtract the horizontal distance to the x-coordinate of the point.

To translate a point up or down, add or subtract the vertical distance to the y-coordinate of the point.

In this case, we have a translation left 2 units and up 5 units. This means that we need to subtract 2 from the x-coordinate and add 5 to the y-coordinate of the point (3,-4). Therefore, the image point is:

(3−2,−4+5)

(1,1)

Therefore, by the graph the answer will be (1,1)

For the given principal $50,000 which was deposited for six years at

4 1/8% interest rate compounded continuously is $14040.97.

As given in the question,

Deposited amount is equal to $50,000

Time period 't' is equal to 6 years

Interest rate 'r' compounded continuously is equal to 4 1/8%

Compounded continuously formula is

A = P\(e^{rt}\)

P is the initial amount deposited

P = $50,000

r = 4 1/8%

 = 33/8 %

 = 0.04125

Substitute the value in the formula we get,

A = ( 50,000 ) × \(e^{0.04125 \times 6}\)

⇒ A = 50,000 × \(e^{0.2475}\)

⇒ A = 64040.97

Interest =Amount - Principal

⇒ Interest = 64040.97 - 50,000

Step-by-step explanation:

The empirical rule regarding mean and standard deviation is that

Therefore between mean and +2 standard deviation or between mean and -2 standard deviation you will find  approximately 95/2 = 47.5% of the values

Between mean and ± 3 standard deviations you will find approximately 97.5/2 = 48.75% of the values

Answer:

(x-14)^2+(y-3)^2=9

Step-by-step explanation:

equation of a circle is (x-h)^2+(y-h)^2=r^2

so center is (14,3) and is tangent externally means

(x-14)^2+(y-3)2=3^2

(x-14)^2+(y-3)^2=9 answer

The equation of a circle is externally tangent to the given circle and has a center at (14, 3) is \((x-14)^2 + (y-3)^2=9\)

The standard formula for finding the equation of a circle is expressed as:

\((x-a)^2+(y-b)^2=r^2\)

where

(a, b) is the centre

r is the radius

Given the center at (14, 3)

If the equation of a circle is externally tangent to the given circle and has a center at (14, 3), then the radius will be 3

Substitute the radius and the centre into the expression above to have:

\((x-14)^2 + (y-3)^2=3^2\\(x-14)^2 + (y-3)^2=9\)

Hence the equation of a circle is externally tangent to the given circle and has a center at (14, 3) is \((x-14)^2 + (y-3)^2=9\)

The surface area of the cylinder is 905 square centimeters

From the question, we have the following parameters that can be used in our computation:

Diameter, d = 12 cm

Height, h = 18 m

This means that

Radius, r = 12/2 = 6 cm

Using the above as a guide, we have the following:

Surface area = 2πr(r + h)

Substitute the known values in the above equation, so, we have the following representation

Surface area = 2π * 6 * (6 + 18)

Surface area = 905

Total water bill for the month is $62.37.

It seems that you may have accidentally left out the total amount of your water bill.

The total amount by simply adding the amounts of the individual bills together:

Total water bill =\($36.34 + $26.03\)

= \($62.37\)

You have not provided enough information to determine your total water bill.

You have only given the amounts of your individual bills from Metro Water Services and Madison Suburban Utility District.

To find your total water bill, you simply need to add the two bills together.

So, the total amount you owe for water this month would be:

Total water bill = \($36.34 + $26.03\)

= \($62.37\)

It appears that you may have forgotten to include the full amount of your water bill by accident.

Simple addition of the separate bill amounts yields the following sum:

Water bill total = \($36.34 + $26.03\)

= \($62.37\)

Your total water bill cannot be calculated because not enough information has been given.

Only the amounts of your individual Metro Water Services and Madison Suburban Utility District bills have been provided.

You just need to combine the two invoices together to get your total water bill.

As a result, this month's total water bill for you would be:

Water bill total =  \($36.34 + $26.03\)

Step-by-step explanation:

whats the rest of the problem or is it just that she rolled a dice

A personal example of a measurement I use routinely is converting weight from U.S. customary units to metric units. Let's convert pounds to kilograms.

To convert pounds to kilograms, we use the conversion factor of 1 pound = 0.453592 kilograms.

For example, if I have a weight of 150 pounds, I can calculate the equivalent weight in kilograms as follows:

150 pounds * 0.453592 kilograms/pound = 68.0388 kilograms

Therefore, 150 pounds is approximately equal to 68.0388 kilograms.

In this conversion, we multiply the weight in pounds by the conversion factor to obtain the weight in kilograms. By using the appropriate conversion factor, we can accurately convert weights from U.S. customary units to metric units.

It's important to note that conversion factors may vary slightly depending on the rounding used and the exact value of the conversion factor.
