what is the negative reciprocal of 7/9​

Answer:

58100

Step-by-step explanation:

The way I see it is move the decimal point over to the right (or left depending on whether its negative or not) however many units the exponent says. After it moves over the number, add the zeroes for the remaining amount of spaces until you have moved it over the correct amount. I'm not sure if that made any sense, but I know the answer is correct.

Answer:

58100

Step-by-step explanation:

We ar asked to write

\(5.81 \times 10 {}^{4} \)

in standard form. If we have a expression,

\(a \times 10 {}^{n} \)

where a is any real number and n is any real number. We just move the decimal to the right (n)places( if n>0) or to the left (n) places (if n<0).

As we can see, n is 4

So we move the decimal in 5.81 to the right 4 times.

We get

\(58100\)

so the answer is 58100

Answer:

\( x_{1} = 0. \: \: \: x_{2} = 4\)

Step-by-step explanation:

\(3(x - 2)^{2} + 1 = 3\)

\(3( {x}^{2} - 4x + 4) + 1 = 13\)

\( {3x}^{2} - 12x + 12 + 1 = 13\)

\( {3x}^{2} - 12x + 13 = 13\)

\( {3x}^{2} - 12x = 0\)

\(x \times (x - 4) = 0\)

\(x = 0\)

\(x - 4 = 0\)

\( \boxed{\green{x_{1} = 0. \: \: \: x_{2} = 4}}\)

The area under the curve between z = −2.0 and z = −1.0 is 0.1359.

We can use tables to find the area under the normal curve between two values of z.

However, tables give areas from z = 0 to z = 3.9 (beyond which there is literally no change). But as the normal curve is symmetric at z = 0, we can use it to find between any two given z values.

For example, for the area under the curve between z = −2.0 and z = −1.0, we can take values for z = 2.0 and z = 1.0; their difference will give the area between z = −2.0 and z = −1.0.

From tables for z = 1.0, we have 0.8413 and for z = 2.0, we have 0.9772 and

Hence, the Area under the curve between z = −2.0 and z = −1.0 is 0.9772−0.8413 = 0.1359.

Answer:

The answer you're looking for is 1470.

Step-by-step explanation:

The method I used was PEMDAS

Since there was no parenthesis, I simplified the exponents.

2.130 x 10³ - 6.6 x 10² = ?
2.130 x 1000 - 6.6 x 100 = ?

After that, I multiplied all terms next to each other.

2.130 x 1000 - 6.6 x 100 = ?
2130 - 660 = ?

The final step I did was to subtract the two final terms and ended up with 1470 as my final answer.

1470 = ?

The highest power of 2 that is less than or equal to 1000 is 2^9, which gives us the required representation of 1000.

In mathematics, a base is the number of digits or distinct symbols used to represent numbers in a positional numeral system. For example, in the decimal system (which we commonly use), the base is 10 because we use 10 distinct digits from 0 to 9.

Now, let's consider the number 1000. In order to find the lowest base in which this could be a valid number, we need to break down 1000 into its constituent digits. Since 1000 has 4 digits, we can represent it as:

1000 = 1 x base^3 + 0 x base^2 + 0 x base^1 + 0 x base^0

where base is the number system we are using. Now, we need to find the lowest value of base that makes this equation valid.

We can see that if we set base = 2, then the equation becomes:

1000 = 1 x 2^9 + 0 x 2^8 + 0 x 2^7 + 0 x 2^6 + 0 x 2^5 + 0 x 2^4 + 0 x 2^3 + 0 x 2^2 + 0 x 2^1 + 0 x 2^0

Here, we have used the binary system, which has a base of 2. As we can see, the highest power of 2 that is less than or equal to 1000 is 2^9, which gives us the required representation of 1000.

The segment FG is reflected by the rule (x, y) → (-x, y). Hence, option C is the correct answer.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century. In geometry, object transformations constitute the foundation for the majority of proofs. Transformations allow us to change any image in a coordinate plane. The rules of transformations can be utilised to better understand the images used in video games.

The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation.

FG has points at F(-6, -3) and G(-3, 6), and F'(6, -3) and G'(3, 6).

It is reflected by the rule (x, y) → (-x, y).

Hence, option C is the correct answer.

The total number of Style B shades that can be loaded into the container is 3,840 Style B shades in total.

A 40-foot container can hold 3,840 Style B shades.

A 40-foot container typically has a volume of 67.7 cubic meters (2,390 cubic feet), but without knowing the size and packing configuration of the shades, it's impossible to determine how many of each type can fit into the container.
Once you provide the dimensions and packing requirements for Style A and Style B shades, I can help you calculate how many of each type can be loaded into a 40-foot container.

Assuming that each carton of Style B shades has the same dimensions and that there is no wasted space within the container, we can calculate the number of cartons that can be loaded into a 40-foot container as follows:

First, we need to determine the total number of cartons that can fit in the container:

8 cartons in width x 40 cartons in length x 2 cartons in height = 640 cartons in total

Next, we need to determine the number of Style B shades in each carton:

6 shades x carton

Therefore, the total number of Style B shades that can be loaded into the container is:

640 cartons x 6 shades per carton = 3,840 Style B shades in total.

So a 40-foot container can hold 3,840 Style B shades.

With regard to a​ regression-based forecast, the standard error of the estimate gives a measure of option (C) the variability around the regression line

The standard error of the estimate in a regression-based forecast is a measure of the variability of the actual data points around the predicted values of the regression line.

It tells us how much the actual data points are likely to deviate from the predicted values, and provides a measure of the accuracy of the forecast. It is not related to the time required to derive the forecast equation, the maximum error of the forecast, or the time period for which the forecast is valid.

Therefore, the correct option is (C) The variability around the regression line.

that is a huge gas tank. that car is practically a tank.

the volume of the gas tank is

4×3×3 = 36 m³

I assume you use liters for liquid mass.

remember

1 meter (m) = 100 centimeter (cm)

10 cm = 1/10 m = 1 decimeter (dm)

1 liter = 10×10×10 cm³ = 1000cm³ = 1 dm³

1 m³ = 10×10×10 dm³ = 1000 dm³ = 1000 liters

so, his gas tank contained 36,000 liters.

he used the 36,000 liters in 45 hours.

Answer:

A: (-6,-5)

B: r = 3

Step-by-step explanation:

To find the center and radius of the circle given by the equation x^2 + y^2 + 12x + 10y + 52 = 0, we first need to rewrite the equation in standard form, which is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is its radius.

Part A:

To rewrite the equation in standard form, we need to complete the square for both x and y. We can do this by adding and subtracting the square of half the coefficient of x and y respectively, as follows:

x^2 + 12x + y^2 + 10y + 52 = 0

(x^2 + 12x + 36) + (y^2 + 10y + 25) = -52 + 36 + 25

(x + 6)^2 + (y + 5)^2 = 9

Now we can see that the equation is in standard form, with center (-6, -5) and radius 3. Therefore, the center point of the circle is (-6, -5).

Part B:

The radius of the circle is given by the square root of the right-hand side of the standard form equation, which is 3. Therefore, the radius of the circle is 3.

Answer:

center: (-6,-5)

radius = \(\sqrt{113}\)

Step-by-step explanation:

completing the square to factor

x2+12x + __ + y2 + 10y + __ = 52

__ = 36                    __ = 25

x2+12x+36 + y2+10y+25 = 52+36+25

(x+6)^2  +  (y+5)^2 = 113

center: (-6,-5)

radius = \(\sqrt{113}\)

Answer:

The velocity function v(t) for the train traveling along a horizontal line is v(t) = 24t^2 - 6t + 2.

To get the velocity function v(t) for a train traveling along a horizontal line according to the position function s(t) = 8t^3 - 3t^2 + 2t + 4, you'll need to take the derivative of the position function with respect to time t.
Step 1: Differentiate the position function s(t) with respect to time t.
v(t) = ds(t)/dt = d(8t^3 - 3t^2 + 2t + 4)/dt
Step 2: Apply the power rule to each term.
v(t) = 3(8t^2) - 2(3t) + 2
Step 3: Simplify the expression.
v(t) = 24t^2 - 6t + 2
So, the velocity function v(t) for the train traveling along a horizontal line is v(t) = 24t^2 - 6t + 2.

The locations of the vertices of the dilated figures are (48,16), (32,40), and (8,24).

This problem can be solved by using the concept of scale factor. Scale factor is useful in finding proportional measurements.

Proportion implies having the same ratio.

Scale factor can be defined as the ratio of the measurement of the model to the measurement of the actual form in the simplest form. In other words, the ratio of any two corresponding lengths in two similar geometric figures is called a scale factor.

If the scale factor is more than 1, that is, scale factor > 1,

then it is an enlargement,

If the scale factor is less than 1, that is, scale factor < 1,

then it is a reduction.

We can obtain the answer by multiplying the given coordinates, first by a scale factor of 4 and then by a scale factor of 2/3.

(18,6) => (18x4, 6x4) => (72,24) => (72x2/3, 24x2/3) => (48,16)

(12,15) => (12x4, 15x4) => (48,60) => (48x2/3, 60x2/3) => (32,40)

(3,9) => (3x4, 9x4) => (12,36) => (12x2/3, 36x2/3) => (8,24)

Therefore, using the concept of scale factor, we get the locations of the vertices of the dilated figures as (48,16), (32,40), and (8,24).
