Find the 10th term of the geometric sequence whose common ratio is 1/3 and whose first term is 7.

Answers

Answer 1

The 10th term of the geometric sequence whose common ratio is 1/3 and whose first term is 7 is [tex]\frac{7}{19683}[/tex].

What is  geometric sequence?

A unique kind of sequence is a geometric sequence. Every term in the series (apart from the first term) is multiplied by a fixed amount to determine the following term. In other words, we multiply the current phrase in the geometric sequence by a constant term (called the common ratio), and then divide the current term in the geometric sequence by the same common ratio to discover the previous term in the geometric sequence.

nth term of geometric series

a(n) = a(1) * r^(n-1)

You are given a(1) = 7, r = 1/3 and n = 10.

a(10) = 7 * 1/3^(10-1)

[tex]7\left(\frac{1}{3}\right)^{10-1}$$[/tex]

Apply exponent rule: [tex]$\left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}$[/tex]

[tex]$$\begin{aligned}& \left(\frac{1}{3}\right)^{10-1}=\frac{1^{10-1}}{3^{10-1}} \\& =7 \times \frac{1^{10-1}}{3^{10-1}}\end{aligned}$$[/tex]

[tex]$$\begin{aligned}& 1^{10-1}=1 \\& =7 \times \frac{1}{3^{10-1}} \\& 3^{10-1}=19683 \\& =7 \times \frac{1}{19683}\end{aligned}$$[/tex]

Convert element to fraction: [tex]$\quad 7=\frac{7}{1}$[/tex]

[tex]=\frac{7}{1} \times \frac{1}{19683}$$[/tex]

Apply the fraction rule: [tex]$\frac{a}{b} \times \frac{c}{d}=\frac{a \times c}{b \times d}$[/tex]

[tex]=\frac{7 \times 1}{1 \times 19683}$$[/tex]

Multiply the numbers: [tex]$7 \times 1=7$[/tex]

[tex]=\frac{7}{1 \times 19683}$$[/tex]

Multiply the numbers: [tex]$1 \times 19683=19683$[/tex]

What is the sampling method that involves taking a random selection of people from a defined population?.

Answers

A sampling method is simple random sampling.

What is sampling method?

In statistical analysis, sampling is the procedure by which researchers choose a specific number of observations from a larger population. The sample strategy will depend on the sort of study being done, although it may involve systematic sampling or just plain random sampling.

A selection of participants from a population are chosen at random by the researcher using simple random sampling, a sort of probability sampling. Every person in the population has the same probability of getting chosen. Then, data are gathered from as much of this randomly selected subgroup as feasible.

Since it only uses one random pick and is very simple, this method is the easiest of all the probability sampling techniques.

b. Is the relation a function? Explain.

Answers

To graph this function, form ordered pairs from the chart. Because the x-axis is denoted to Radius and the y-axis to Area, we will want to graph the radius and corresponding area. Remember, x-coordinates always are graphed first, then the y-coordinate to plot a point.

A.) From the table, we can create the following ordered pairs in the form (x, y):

(1, 3) (2, 12) (3, 27) (4, 48) (5, 75)

Simply start at 0 and move left or right in the x-axis the amount of units the fist value says. Then, from that position, move up or down along the y-axis the value of the second coordinate. For example, in the pair (1, 3), you will move 1 unit right (+), then 3 units up from that position and plot the point. The point should be 1 space to the right and 3 spaces up from there.

B.) This graph is a function because it passes the vertical line test, meaning no x-value leads to two y-values. Every domain value is paired to exactly one range value.

The exponential function passes through the points (-1,4/5) and (1,20) will be y = 4 × [tex]5^{x}[/tex].

What is an exponential function?

In mathematics, an exponential function is a relationship of the type y = ax, where x is an independent variable that spans the entire real number line and is expressed as the exponent of a positive number.

In other meaning, an exponential function is that function above which a variable x has imposed.

Suppose the exponential function as

y = a[tex]e^{bx}[/tex]

Substitute, (-1,4/5)

4/5 = a[tex]e^{-b}[/tex]                             (1)

Substitute, (1,20)

20 = a[tex]e^{b}[/tex]                                (2)

Multiply (1) with (2)

(4/5)20 = a[tex]e^{-b}[/tex] × a[tex]e^{b}[/tex]

4 × 4 = a²

a = 4

Substitute, a = 4 into (2)

20 = 4[tex]e^{b}[/tex]    

[tex]e^{b}[/tex] = 5

Take log on both sides of the above equation,

ln [tex]e^{b}[/tex]  =  ln 5

b = ln 5

Substitute a = 4 and b = ln 5 into y = a[tex]e^{bx}[/tex]

y = 4 e^(x(ln 5)) = 4 e^(ln5^x)

y = 4 × [tex]5^{x}[/tex]

Hence "The exponential function passes through the points (-1,4/5) and (1,20) will be y = 4 × [tex]5^{x}[/tex]".

The radioactive element​ carbon-14 has a​ half-life of 5750 years. A scientist determined that the bones from a mastodon had lost ​80.2% of their​ carbon-14. How old were the bones at the time they were​ discovered?

Answers

The age of the bones when they were discovered is 13439.66 years

What is half-life of an element?

The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.

Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value

The decay constant λ is = 0.693/t½

where t½ is the half-life of the element

Given data ,

The radioactive element​ carbon-14 has a​ half-life of 5750 years

So , the value of t½ = 5750 years

Now , the decay constant λ = 0.693 / t½

Substituting the values in the equation , we get

Decay constant λ = 0.693 / t½

Decay constant λ = 0.693 / 5750

Decay constant λ = 1.205 x 10⁻⁴

N=N₀e ^ −λt

where N₀ = Mass of radioactive element initially

N = Mass of radioactive element after time t

Apply natural logarithm on both the sides of the equation , we get

ln N = ln N₀ - λt

Let N0 be 100 then N will be 100 - 80.2 = 19.8

Substituting the values in the equation , we get

ln 19.8 = ln 100 -  1.205 x 10⁻⁴ ( t )

ln [ 19.8 / 100 ] = - 1.205 x 10⁻⁴ ( t )

-1.61948 = -1.205 x 10⁻⁴ ( t )

Therefore , the value of t is

t = -1.61948 / -1.205 x 10⁻⁴

t = 1.343966 x 10⁴

t = 13439.66 years

Therefore , the value of t is 13439.66 years

Hence ,

The age of the bones when they were discovered is 13439.66 years

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

We know lines perpendicular to each other have slopes that are negative reciprocals of each other.

Given line is 4x - 6y = - 60 ⇒ - 6y = - 4x - 60 ⇒ y = (2/3)x + 10.

Now the line perpendicular to it will have a slope of (-3/2).

What is distance between two points?

The distance between two points in a plane is the length of the line segment separating the two points. Typically, the equation

d=√((x2 - x1)^2 + (y2 - y1)^2) is used to calculate the distance between two points.

Suppose we have a pair of points, with the coordinates given as follows:

[tex](x_1, y_1)[/tex]  and  [tex](x_2, y_2)[/tex].

The two points form a right triangle, in which the sides are given as follows:

[tex]y_2-y_1\\x_2-x_1[/tex]

The distance between these two points is given by the hypotenuse of the right triangle.

Hence, applying the Pythagorean Theorem, the distance is obtained as follows:

[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

In this problem, the coordinates of the points are given as follows:

(−3, −13) and (11, 9).

Hence the correct option is given by option B.

Answers

Answer:

the answer is 5

Step-by-step explanation:

(Add 10r to both sides)

-7-7r+10r= 8

Then -7+3r = 8

(Add 7 to both sides)

3r = 8+7

3r = 15

Divide both sides by 3.

In triangle WXY, the measure of W is 10 less than the measure of X and the measure of Y is 14 less than the measure of X. Find the measure of each angle

Answers

X = 63°

W = 60°

Y = 57° are  the measure of each angle in triangle.

In math, what is a triangle?

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.

W = X - 10

Y = X - 14

X + W + Y = 180    substitute

X + (X - 10) + ( X - 14)

  = 3 X - 24 = 180

3X = 180 + 24.

 X = 204/3

X =  68

W =  58

Y =  54

Write out, in paragraph form, a plan for completing the following proof.

For example, will you prove triangles congruent? How? By what theorem?

Given:

AR = AQ

RT = QS

Prove:

∠ RAT = ∠ QAS

Can someone help me understand how to answer this

Answers

Because AR = AQ, you have an isosceles triangle with triangle RAQ.  This also means ∠ARQ = ∠AQR.

You're also told that RT = QS, so this gives you SAS to show triangle ART = triangle  AQS.

   side: AR = AQ

   angle: ∠ART = ∠AQS

   side: TR = QS

Knowing that the two triangles are congruent gives you that the two top angles are also congruent.
