(x + 2) ^2 + (y - 3) ^2 + (z - 1^2 = 1 is an equation for a sphere with a center of (-2,3,1) and a tangent to the xz plane.

An algebraic equation, also known as a polynomial equation, is a mathematical equation of the form P=0, where P is a polynomial with coefficients in some field, most commonly the field of rational numbers.

Here,

The equation of a sphere with center (x0, y0, z0) and radius r is given by:

(x - x0)^2 + (y - y0)^2 + (z - z0)^2 = r^2

In this case, the center of the sphere is (-2, 3, 1) and it is tangent to the xz plane, which has equation z = 0. Hence, the sphere must have a z-coordinate of 1, so the equation becomes:

(x + 2)^2 + (y - 3)^2 + (z - 1)^2 = r^2

We need to find the value of r such that the sphere is tangent to the xz plane. If a sphere is tangent to a plane, it means that the distance between the center of the sphere and the plane is equal to the radius of the sphere. The distance between a point (x0, y0, z0) and the plane z = k is given by |z0 - k|. Hence, the distance between the center of the sphere (-2, 3, 1) and the xz plane is given by:

|1 - 0| = 1

Therefore, the radius of the sphere is equal to 1, so the equation of the sphere is:

(x + 2)^2 + (y - 3)^2 + (z - 1)^2 = 1^2

Simplifying, we obtain the equation of the sphere:

(x + 2)^2 + (y - 3)^2 + (z - 1)^2 = 1 is an equation for the sphere with center (-2,3,1) that is tangent to the xz plane.

The rational, irrational and imaginary zeroes for function c(x) = 18x³ + 9x² - 2x -1 are:

To solve this proble, we will use Rational Root Theorem and Descartes Rules of Signs.

Based on Rational Root Theorem, we can find that the function c(x) has rational roots of:

c(x) = 18x³ + 9x² - 2x -1

possible roots = ± {factors of a₀} / {factors of aₙ}

From the given function, we can use the possible roots concept:

Possible roots = ± factors of 18

                              factors of 1

Possible roots = ± {1, 2, 3, 6, 9, 18}

                                     {1}

We can conculde some possible roots such as: {-18, -9, -6, -3, -2, -1, 1, 2, 3, 6, 9, 18}

Next, we need to confirm which possible roots are the rational roots by subtitute the possible roots into the function c(x). The rational roots will produce the function equals to zero (0).

c(1) = 18(1)³ + 9(1)² - 2(1) -1

c(1) = 18 + 9 - 2 - 1 = 24 --> irrational roots

c(2) = 18(2)³ + 9(2)² - 2(2) -1

c(2) = 18(8) + 9(4) - 2(2) - 1

c(2) = 144 + 36 - 4 - 1 = 175 --> irrational roots

c(3) = 18(3)³ + 9(3)² - 2(3) -1

c(3) = 18(27) + 9(9) - 2(3) - 1 = 560 --> irrational roots

c(6) = 18(6)³ + 9(6)² - 2(6) -1

c(6) = 4.199 --> irrational roots

c(9) = 18(9)³ + 9(9)² - 2(9) -1

c(9) = 13,832 --> irrational roots

c(18) = 18(18)³ + 9(18)² - 2(18) -1

c(18) = 107,855 --> irrational roots

c(-1) = 18(-1)³ + 9(-1)² - 2(-1) -1

c(-1) = -18 - 9 + 2 - 1 = -8 --> irrational roots

c(-2) = 18(-2)³ + 9(-2)² - 2(-2) -1

c(-2) = -105 --> irrational roots

c(-3) = 18(-3)³ + 9(-3)² - 2(-3) -1

c(-3) = -400 --> irrational roots

c(-6) = 18(-6)³ + 9(-6)² - 2(-6) -1

c(-6) = -3,553 --> irrational roots

c(-9) = 18(-9)³ + 9(-9)² - 2(-9) -1

c(-9) = -12,376 --> irrational roots

c(-18) = 18(-18)³ + 9(-18)² - 2(-18) -1

c(-18) = -120,176 --> irrational roots

Next, we will try to use Descartes Rule of Signs:

c(x) = 18x³ + 9x² - 2x -1

c(x) = +18x³ + 9x² - 2x -1

The sign is changing once, then the function c(x) has 1 positive roots.

Next, we change the value of (x) into (-x) and put it into the function:

c(-x) = 18(-x)³ + 9(-x)² - 2(-x) -1

c(-x) = -18x³ + 9x² + 2x -1

The signs are changing twice on between the first and second coefficient and between third and fourth. Hence the funciton c(x) has 2 or zero negative roots.

Exterior angles are those that run parallel to a polygon's inner angles but are located outside of it so The value of x is 77.

Exterior angles are those that run parallel to a polygon's inner angles but are located outside of it. The sum of the two internal opposed angles determines the size of an outside angle.

The total of the inner angles is 180 degrees, or 180. (43-34). The outer angles measure 43 , 34, and 120 degrees, respectively, because they are an addition to the inside angles. The outer angles add up to a total of 360 degrees.

Calculate the outside angle's dimensions.

< u = 43 + 34 - 180 = 103.

The given points (a) lies on the line, (b) does NOT lie on the line, and (c) lies on the line.

A point lies on a line if and only if it can be written as the sum of a scalar multiple of a direction vector and a position vector of the line.

To determine if each point lies on the line defined by X = -5 + t, y = 6t, and z = 6+ t, we can substitute each point into this equation to see if it is equivalent.

(a) (0, 30, 11):

-5 + t = 0, so t = 5

y = 6t = 6 × 5 = 30

z = 6 + t = 6 + 5 = 11

So, (0, 30, 11) can be written as -5 + 5i + 6 × 5j + 6k = -5i + 30j + 11k, which lies on the line.

(b) (5, 6, 11):

-5 + t = 5, so t = 10

y = 6t = 6 × 10 = 60

z = 6 + t = 6 + 10 = 16

So, (5, 6, 11) does NOT lie on the line.

(c) (-7, -12, 4):

-5 + t = -7, so t = -2

y = 6t = 6 × -2 = -12

z = 6 + t = 6 + -2 = 4

So, (-7, -12, 4) can be composed as -5 - 2i + -12j + 4k = -7i - 12j + 4k, which lies on the line.

Therefore, (a) lies on the line, (b) does NOT lie on the line, and (c) lies on the line.

As x increases from x=1 to x=5, the value of h remains constant at 4 and the output of the function v(x) changes from v(1) = 5 to v(5) = 29, with a difference of 24.

A function is a mathematical rule that assigns a unique output for every input.

Given the function h = 4, we can see that the output is always 4, regardless of the input value.

Now, if we consider the function

=> v(x) = x² + h,

we can see that the output is dependent on the input x and the constant value of h. As x increases from x=1 to x=5, the output of v(x) will also change.

We can calculate the value of v(1) as

=> v(1) = 1² + 4 = 5.

And similarly, we can calculate the value of v(5) as

=> v(5) = 5² + 4 = 29.

The difference between v(5) and v(1) can be calculated as

=> v(5) - v(1) = 29 - 5 = 24.

16 m of electric wire costs 3214, how much will jermaine's father spend for the 11 m of wire cost?​

By reading values from the given graph of f, use five rectangles to L a lower estimate and an upper the area under the given graph of f from x = 0 to x = 10 are as follows :

Using the five rectangle method , for upper limit choose the area of vertically longer rectangle in each case and vice versa for lower limit.

Upper limit = 5x2+4x2+2x2+1x2+1x2 = 26

Lower limit = 3x2+1x2+0x2+0x2+0x2 = 8

(b) Use the same approach as in the case above, the new estimates using ten rectangles in each case.

Upper limit = 5x1+4x1+4x1+3x1+2x1+2x1+1x1+1x1+1x1+1x1 = 24

Lower limit = 4x1+3x1+2x1+1x1+1x1+0x1+0x1+0x1+0x1+0x1 = 11

The equation of sphere is x² + 10x + y² - 4y + z² - 12z + 41 = 81.

The collection of all points that are distanced from the centre by a certain amount, or radius, is referred to as a sphere in three dimensions. The shape of a sphere is spherical and symmetrical.

The distances between each surface point and the centre are equal throughout the three dimensions of the solid. It has a surface area and a volume based on its radius. The formula for a sphere's volume is V = 4/3 r3, where r is the radius and V is its volume. Half of a sphere's diameter makes up its radius.

The equation of a sphere with center (x0, y0, z0) and radius r is given by:

(x - x0)² + (y - y0)² + (z - z0)² = r²

So, for a sphere with center (-5, 2, 6) and radius 9, the equation would be:

(x + 5)² + (y - 2)² + (z - 6)² = 9²

which simplifies to:

x² + 10x + y² - 4y + z² - 12z + 41 = 81.

It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.

Now, According to the question:

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Standard deviation is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.

At the equator, an arc-second of longitude approximately equals an arc-second of latitude, which is 1/60th of a nautical mile (or 101.27 feet or 30.87 meters)

1° = 11(5280) ft

1° = 58080 ft

1' = 58080 ft/ 60  

1" = 58080 ft / 3600

At the equator 360° = 3960 miles

1° = 11 miles

Knowing that one mile is 5280 feet we can determine the length of one minute and one second.

An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the north pole and the south pole, at 0 degrees latitude. An equator divides the planet into a northern hemisphere and a southern hemisphere. Earth is widest at its Equator.

During the resting phase, the electrical potential energy of a typical k ion inside of the cell is 80 eV. So the option 4 is correct.

The definition of electric potential energy is

U = qV

Individual particle electric charges are always multiples of the fundamental charge e. (the charge on a single proton). Use of the constant e as a unit is frequently more practical than replacing e with a numerical value. A proton with a potential of 80 V therefore has energy

U = qV

We can write it as

U = e(80 V)

So U = 80 eV

Ionic Potentials across Cell Membranes Conceptual Question

In its resting state, the membrane surrounding a neuron is permeable to potassium ions but only slightly permeable to sodium ions. Thus, positive K ions can flow through the membrane in an attempt to equalize K concentration, but Na ions cannot as quickly.

This leads to an excess of Na ions outside of the cell. If the space outside the cell is defined as zero electric potential, then the electric potential of the interior of the cell is negative. This resting potential is typically about -80 mV. A schematic of this situation is shown in the figure.

During the resting phase, what is the electrical potential energy of a typical K ion inside of the cell?

1. -40 meV

2. +40 meV

3. -80 meV

4. +80 meV

5. 0 meV
