The given series ∑=3[infinity]710 is a geometric series with the first term a=3 and the common ratio r=7/10. Therefore, the sum of the given geometric series is 10, and the series is convergent.

To determine whether the series converges or diverges, we can apply the formula for the sum of an infinite geometric series, which is S = a / (1 - r). Plugging in the values for a and r, we get:

S = 3 / (1 - 7/10) = 3 / (3/10) = 10

Therefore, the sum of the infinite geometric series is 10. This means that as we add up more and more terms of the series, the sum gets closer and closer to 10. In other words, the series converges to a finite value of 10.

In conclusion, the sum of the given geometric series is 10, and the series is convergent.

Answer:

Step-by-step explanation:

Answer:

1) y = -x -1

2) y + 4 = 3( x -2)

3) y = x + 1

Step-by-step explanation:

1)

The slope is the change in y over the change in x.  The y values from the points given is 0 and -1.  The x values from the points given is -1 and o

Slope: \(\frac{o - -1}{-1 - o}\) = \(\frac{1}{-1}\) = -1

y -intercept

y = mx + b  Use the point (0,-1) and the slope to solve for b

y = -1

m = -1

x = 0

y = mx + b

-1 = -1(0) + b

-1 = 0 + b

-1 = b  This is the y intercept.

y = mx + b

y = =x -1

2)

point-gradient form is

y -y = m (x-x)

y - -4 = 3 (x -2)

y + 4 = 3( x - 2)

3)

Parallel lines have the same slope.

slope is 1.  Use this and the point (0,1) to solve for b

y = mx + b

1 = 1(0) + b

1 = 0 + b

1 = b

y = x + 1

Step-by-step explanation:

The quadratic function is x² - 13x + 30.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function.

A quadratic function is one of the form:

f(x) = ax²+ bx + c,

where a, b, and c are numbers with a not equal to zero.

Let m and n be the zeros of the quadratic function.

So, the quadratic function is

f(x) = c(x-m)(x-n),

where c is the constant common term and m, n are zeros.

Simplifying,

f(x) = x² -mx - nx + mn.

Here, given zeros of the quadratic equation are 10 and 3.

That means,

if function is subjected to x.

Then (x-10) and (x-3) are factors of the quadratic function.

To write a quadratic function:

we multiply the factors,

(x-10)(x-3)

= x² -10x - 3x + 30

= x² - 13x + 30

Therefore, the quadratic function is x² - 13x + 30.

Answer:

x=6

Step-by-step explanation:

The correct answer of the operation is option B: 4x^2 - 9.

To perform the operation (2x-3)(2x+3), we can use the FOIL method, which stands for First, Outer, Inner, Last. Let's go through the steps:

First: Multiply the first terms of each binomial.

(2x)(2x) = 4x^2

Outer: Multiply the outer terms of each binomial.

(2x)(3) = 6x

Inner: Multiply the inner terms of each binomial.

(-3)(2x) = -6x

Last: Multiply the last terms of each binomial.

(-3)(3) = -9

A binomial is a two-term algebraic expression that contains variable, coefficient, exponents and constant, a binomial is an expression that has two unlike terms connected through an addition or subtraction operator in between.  

Now, let's combine the like terms:

4x^2 + 6x - 6x - 9

Notice that the terms 6x and -6x cancel each other out.

Simplifying further, we have:

4x^2 - 9

The correct answer is option B: 4x^2 - 9.

The cost of one daylily is $2.

The cost of one geranium is $1.

Let x be the cost of one daylily and y be the cost of one geranium. We can set up the following system of equations:

```

x + 3y = 12

10x + y = 33

```

We can solve this system of equations by multiplying the first equation by -10 and adding it to the second equation. This gives us:

```

9x = 21

x = 2

```

Substituting this value into either of the original equations, we can solve for y:

```

2 + 3y = 12

3y = 10

y = 3.33

```

Therefore, the cost of one daylily is $2 and the cost of one geranium is $1.

Here is a table showing the steps involved in solving the system of equations:

| Equation | Step | Result |

|---|---|---|

| x + 3y = 12 | Multiply by -10 | -10x - 30y = -120 |

| 10x + y = 33 | Add the two equations | -29y = -87 |

| y = -87 / -29 | Divide both sides by -29 | y = 3 |

| x + 3(3) = 12 | Substitute y = 3 into the first equation | x + 9 = 12 |

| x = 2 | Subtract 9 from both sides | x = 2 |

As you can see, the solution to the system of equations is x = 2 and y = 3. This means that the cost of one daylily is $2 and the cost of one geranium is $1.

I hope i helped you! I wish you luck on the test!

8 × \(10^5\) is 200 times greater than 4 × \(10^3\)  as according to multiplying and dividing as per the scientific notation of multiplication and division.

A kind of representation of number which is some power of 1/10 can also be expressed in as easily in scientific notation.

1/10 = \(10^{-1\)  (“ten to the minus one power”)

More generally, the expression “\(10^{-n\)” (where n is a whole number) means (1/10) n. Thus

\(10^{-3\) = \(\frac{1}{10}^{-3}\)

= 1/1000

\(10^{-8\) = \(\frac{1}{10}^{-8\)

= 1/100,000,000

Scientific notation was invented to help scientists (and science students) deal with very large and very small numbers, without getting lost in all the zeros.

Herein this question

8 × \(10^5\) can also thus be written as 2 x 4 × \(10^5\). On dividing with 4 × \(10^3\) we get 2 x \(10^2\). Thus, it is 2 x \(10^2\) i.e., 200 times larger than 4× \(10^3\).

The expression “10n”, where n can be stated as a whole number, simply means that “10 is raised to the nth power,” or in other words, a number that is got by using 10 as a factor n times.

You can also notice that the number of zeros that are present in the ordinary decimal expression is absolutely equal to the power to which thus 10 is raised.

If any kind of number is expressed in words, first we have to write it down as an ordinary decimal number and then we have to convert it. Thus, the value “ten million” becomes 10,000,000. There are a total of seven zeros, so in powers of ten notation ten million is written \(10^7\).

the 15 different ways can he select the days on which to have pizza

What is combination?

A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components

An equation for the plane consisting of all points that are equidistant from the points (1,4,4) and (-4, 1, 2) is 5x+3y+2z-6=0

Given, the points are (1, 4, 4) and (-4, 1, 2).

We have to find an equation for the plane consisting of all points that are equidistant from the given points.

Let the parametric point be (x, y, z) on the plane which is equidistant from the given points.

Using the distance formula:

\(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1} )^2 } }\)

Distance between the points (x, y, z) and (1, 4, 4)

=\(\sqrt{(x-1)^2+(y-4)^2+(z-4)^2}\)

Distance between the points (x, y, z) and (-4, 1, 2)

=\(\sqrt{(x-(-4)^2+(y-1)^2+(z-2)^2}\\\\ \sqrt{(x+4)^2+(y-1)^2+(z-2)^2}\)

Given, \(\sqrt{(x-1)^2+(y-4)^2+(z-4)^2}=\sqrt{(x+4)^2+(y-1)^2+(z-2)^2}\)

By using algebraic identity,

(a-b)² = a²-2ab+b²

(a+b)² = a²+2ab+b²

(x² - 2x + 1)+(y²-8y+16)+(z²-8z+16)=(x²+8x+16)(y²-2y+1)+(z²-4z+4)

x²+y²+z²-2x-8y-8z+1+16+16=x²+y²+z²+8x-2y-4z+16+1+4

By grouping,

-2x-8x-8y+2y-8z+4z+33-21

-10x-6y-4z+12=0

Dividing by -2 into both sides,

5x+3y+2z-6=0

According to the statement the correct answer is option C - yes, the data are distributed evenly around the line of fit.

To determine if a model is a good fit for a data set, one needs to evaluate how closely the data points align with the line of fit. The line of fit represents the best possible straight line that can be drawn through the data points. If the data points are too far from the line of fit or too close to the line of fit, then it is an indication that the model is not a good fit for the data.
Option A states that the data points are too far from the line of fit, indicating that the model is not a good fit for the data. Option B states that the data points are too close to the line of fit, which is not necessarily a good or bad thing as it depends on the level of accuracy required for the analysis. Option C states that the data points are evenly distributed around the line of fit, which indicates that the model is a good fit for the data. Lastly, option D states that the line of fit touches at least one point in the data set, which is not sufficient to determine if the model is a good fit for the entire data set.
Therefore, the correct answer is option C - yes, the data are distributed evenly around the line of fit.

Given the center (-1, 2) and the point (-6, -3).So equation of the circle is (x + 1)^2 + (y - 2)^2 = 50                                            

Find the equation of a circle, we use the standard form:
(x - h)^2 + (y - k)^2 = r^2

 Step 1: Determine the center (h, k) of the circle.
The center of the circle is given as (-1, 2). Therefore, h = -1 and k = 2.

Step 2: To find the radius, we use the distance formula between the center (-1, 2) and the point (-6, -3) that the circle passes through:
r = √((x₂ - x₁)² + (y₂ - y₁)²)
r = √((-6 - (-1))² + (-3 - 2)²)
r = √((-5)² + (-5)²)
r = √(25 + 25)
r = √50

Step 3: The standard form of the equation of a circle is (x - h)² + (y - k)² = r². Plug in the values for h, k, and r from steps 1 and 2:
(x - (-1))² + (y - 2)² = (√50)²
(x + 1)² + (y - 2)² = 50

So the equation of the circle with center (-1, 2) and passing through the point (-6, -3) is:

(x + 1)² + (y - 2)² = 50
