The fourth term in the sequence is 7.

Geometric progression is a sequence of numbers such that the ratio of two consecutive numbers is the same for whole sequence.

This ratio is common ratio.

Given is the first term of a sequence.

c(1) = 56

Also, there is given an nth term of the sequence.

c(n) = c(n - 1) [tex]\frac{1}{2}[/tex]

This means that every term in the sequence is the half of the preceding term.

So this is a geometric sequence with a common ratio of 1/2.

nth term of a geometric sequence = a. rⁿ⁻¹, where a is the first term and r is the common ratio.

Given, first term = 56 and we found r = 1/2

c(4) = 56 × ([tex]\frac{1}{2}[/tex])⁴⁻¹ = 7

Hence the fourth term in the given sequence is 7.

There are two imaginary roots and one real root of the equation

Generally, In mathematics, the root of an equation is a value that satisfies the equation. In other words, it is the value of the variable for which the equation is true. For example, in the equation x^2 - 4 = 0, the roots are +2 and -2, because when either of these values is substituted for x, the equation becomes true.

There are different methods for finding roots of an equation, depending on the type of equation. For example, some equations can be solved by factoring, while others require the use of more advanced techniques such as the quadratic formula or numerical methods like the Newton-Raphson method.

In general, finding the roots of an equation is an important task in mathematics and has many practical applications in fields such as engineering, physics, and finance.

Through the aid of future value If no withdrawals or new deposits are made, the account's value following the tenth deposit should be $15,093.47.

The implied value of an asset as of a particular date in the future based on a growth rate assumption is known as the Future Value (FV). This area of mathematics examines how random events happen. The value might be between 0 and 1. The mathematical idea of probability aids in predicting the possibility of specific events. In general, probability relates to how probable something is to happen. The interest rate assumption, or the rate of return on the initial amount of capital invested, or the present value, determines the projected future value (PV).

Calculation of the value:

The initial deposit is $1.200

The rate of interest is 5%

The area of a rectangle is given by the product of its length and width. Therefore, the area of the rectangle is:

A(x) = L(x) ⋅ W(x) = 2x(8x^2 - 4x + 1)

Simplifying the expression, we get:

A(x) = 16x^3 - 8x^2 + 2x

Let's call the number of months that it takes Pablo to save $700 as "m". The amount of money Pablo has saved after "m" months can be represented by the equation:

y = 200 + 125m

where y is the total amount of money saved after "m" months.

To find the number of months it will take Pablo to save $700, we can set y equal to $700 and solve for m:

700 = 200 + 125m

500 = 125m

m = 500 / 125 = 4

So it will take Pablo 4 months to save $700.

The equation in slope-intercept form is:

y = 125m + 200

where m is the number of months and y is the total amount of money saved. The slope of the line is 125, which represents the amount added to the savings each month, and the y-intercept is 200, which represents the initial amount of money Pablo received for graduation.

The AB intersects circle P if PA is 7mm and PB is 3mm it must exit the circle, and it has 2 contact points.

PA is longer than the radius of the circle so Point A must be outside of the circle.

Two or more circles intersect at one point. Two circles can be tangent to each other in two different ways.

here, we have,

We have given that,

AB lies in the same plane as circle P, which has a radius of 6 mm.

PB is less than the radius of the circle so Point B must be inside the circle.

Since the ray is going from A to B it is coming inside the circle and continuing in the other direction.

Therefore, it must exit the circle, giving us 2 contact points.

All 3 angles of a triangle must equal 180, so let's make these equal to that

True, the standard deviation is a resistant measure of spread.

The standard deviation is calculated as the square root of the variance of the data set. Variance is calculated as the average of the squared differences between each data point and the mean of the data set. The standard deviation is the square root of this average.

In mathematical terms, the standard deviation can be calculated using the following formula:

σ = √(1/n ∑(x - μ)²)

Where σ is the standard deviation, n is the number of data points in the data set, x is the value of the i-th data point, and μ is the mean of the data set.

The standard deviation is an important measure because it gives an idea of how much the individual values in a data set differ from the mean.

In summary, the standard deviation is a resistant measure of spread because it gives a robust measure of the spread of the data in a set and is not easily influenced by outliers or extreme values.

Answer:

To find the radius of a ball that holds 66 cubic centimeters of air:

1. Substitute the given volume into the equation r= (3v/4π): r = (3*66/4π).

2. Simplify the equation: r = (198/4π).

3. Calculate the value of 4π: 4π = 12.57.

4. Divide 198 by 12.57: r = 15.75.

5. The radius of the ball that holds 66 cubic centimeters of air is 15.75 cm.

Answer:

Step-by-step explanation:

To find the radius of a sphere that holds 66 cubic centimeters of air, we can use the formula provided in the question:

r = (3v/4π)

where v is the volume of the sphere. We are given that the volume of the sphere is 66 cubic centimeters, so we can substitute this value into the formula:

r = (3 x 66) / (4 x π)

Simplifying this expression:

r = 198 / (4π)

Using a calculator to evaluate this expression:

r ≈ 15.8267

Therefore, the radius of the sphere that holds 66 cubic centimeters of air is approximately 15.8267 centimeters.

The area of the isosceles trapezoid is 72 square units.

A quadrilateral having at least one set of parallel sides and equal length non-parallel sides is called an isosceles trapezium. To put it another way, it is a trapezium whose two non-parallel sides are congruent. The trapezoid's parallel sides are referred to as the bases, and the segments that link the bases are referred to as the legs. The angle between the bases of an isosceles trapezoid determines its height.

Given:

[tex]\[d = 12 \quad \text{(length of one diagonal)}\][/tex]

Let;

[tex]\[h = \text{height of the trapezoid}\][/tex]

[tex]\[a = \text{smaller base of the trapezoid}\][/tex]

[tex]\[b = \text{larger base of the trapezoid}\][/tex]

Using the given information that the height and median are equal, we have:

[tex]Median(m)=\frac{1}{2} {(a+b)}\\\\Height(h)=\frac{1}{2} {(a+b)}\\\\2h=a+b ........(1)[/tex]

[tex]\[\text{Area} = \frac{1}{2} \cdot (a + b) \cdot h\][/tex]

[tex]\[\text{Area} = m \cdot h\] = h^2 ............(2)[/tex] (∵ [tex]Median(m)=\frac{1}{2} {(a+b)}[/tex] and m=h)

Now,

[tex]\[ d = \sqrt{h^2 + \frac{(a+b)^2}{4}} \][/tex] for isosceles trapezoid,

[tex]\[ 12^2 = h^2 + \frac{(a+b)^2}{4}}[/tex]

[tex]\[ 12^2 = h^2 + \frac{(2h)^2}{4}}[/tex]   (∵from eq (1))

[tex]\[ 12^2 = h^2 + {(h)^2}}\\ \\144= 2h^2\\\\h^2=72 ..........(2)[/tex]

Lastly, we may change the values of "a," "b," and "h" in the following formula to find the area as;

[tex]\[\text{Area} = \frac{1}{2} \cdot (a + b) \cdot h\][/tex]

[tex]\[\text{Area} = \frac{1}{2} \cdot (2h) \cdot h\][/tex]
