Answer:

[tex]a_n=3(-3)^{n-1}[/tex]

Step-by-step explanation:

Geometric sequence

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

where:

Given:

To find the common ratio r, divide consecutive terms:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{-9}{3}=-3[/tex]

      ❖ Add 4 on both sides:-

x≤9+4

x≤13

  ✯ So the values of x less than or equal to 13 will make this inequality true.

To solve this problem, we have to find the area of the semi circles and the area of the rectangle and add them up together.

The area of the field is equal to 8719.36m^2

Let us start by finding the area of the rectangle.

Data;

Area of a rectangle is given as

[tex]a = length * width \\a = 86 * 64\\a = 5504m^2\\[/tex]

The area of the rectangle is 5504m^2

Area of the semicircle

The formula of a semi circle is given as

[tex]A = \frac{1}{2} \pi r^2[/tex]

But since we have two semi circles here, we can simply multiply it by two and the formula becomes

[tex]A = 2 * \frac{1}{2} \pi r^2\\A = \pi r^2[/tex]

But in the question, we have the diameter of the semi circle as the length of the rectangle.

[tex]radius = \frac{diameter}{2} \\radius = \frac{64}{2} \\radius = 32m[/tex]

The radius of the semicircle is 32m

Area of the semicircle is

[tex]A = \pi r^2\\A = 3.14 * 32^2\\A = 3215.36m^2[/tex]

The area of the field is

[tex]area of field = 3215.36 + 5504\\area = 8719.36m^2[/tex]

The area of the field is equal to 8719.36m^2

The sum of the first 14 terms of the finite geometric series 0.5+ (-1) +2+... is -2730.5

The series is given as:

0.5+ (-1) +2+...

The above series is a geometric series, with the following parameters:

The sum of the first 14 terms is calculated using:

[tex]S_n= a *(1 - r^n) \div (1 - r)[/tex]

So, we have:

[tex]S_{14}= 0.5 *(1 - (-2)^{14}) \div (1 + 2)[/tex]

Evaluate

[tex]S_{14}= -2730.5[/tex]

Hence, the sum of the series is -2730.5

The Cost of operating the theater if there are 100 people at a show is 20,000Rs.

The theater is a place where the movies are shown on big screens and Speakers are used for the clear audio of the movie.

In a theater, there will be 3 to 4 shows for a movie or a different movie.

Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.

The average cost of a college education has gone up dramatically.

Consider a ticket cost of 200rs.

For 100 people in a show,

Cost = 200 × 100

Cost = 20,000.

Hence the cost of operating a theater if there are 100 people at a show is 20,000Rs.

Answer: 148.5 miles

Step-by-step explanation:

450/50 gals= 9 miles can be driven for every 1 gallon.

Since we now know that our car uses 1 gallon of gas for every 9 miles we drive, we can now multiply the 9 miles with the 16 1/2= 16.5. So 16.5x9=148.5.

With our 16 1/2 gas tank, we can travel at least 148.5 miles before running out of gas.

[tex]cos(\theta)=\cfrac{\stackrel{adjacent}{12}}{\underset{hypotenuse}{13}}\implies cos^{-1}[cos(\theta)]=cos^{-1}\left( \cfrac{12}{13} \right) \\\\\\ \theta =cos^{-1}\left( \cfrac{12}{13} \right)\implies \theta \approx 22.62^o[/tex]

Step-by-step explanation:

Answer:

  a.  2, 3, 6

  b.  a/b × c = 1

  c.  a = 2, b = 6, c = 3  or  a = 3, b = 6, c = 2

Step-by-step explanation:

Apparently, Erica wants to multiply a fraction by a whole number to get a result of 1. That means the fraction is the multiplicative inverse of the whole number.

__

There is only one set of three unique numbers among those given such that one of them is a composite number with the other two as factors. Erica must choose 2, 3, and 6.

__

If the three numbers are represented by a, b, c, Erica wants ...

  a/b × c = 1

__

Multiplying the equation by b gives ...

  ac = b

Among the numbers 1–6, only 2×3 = 6 will satisfy this equation. Erica can choose either of ...

  a = 2, b = 6, c = 3   ⇒   (2/6)×3 = 1

  a = 3, b = 6, c = 2   ⇒   (3/6)×2 = 1

Rearrange the terms:

[tex]4x - 3x = - 6 + 2[/tex]

Combine like terms:

[tex]x = - 6 + 2[/tex]

Calculate:

[tex]x = - 4[/tex]

Answer:
x = 1/2
Step-by-step explanation:
Combine exponents
4x-x-2=-3^2+3xx
4x-x-2=-3x^2+3x^2
Combine like terms
4x-2=-3x^2+3x^2
4x-2=0
Add 2 to both sides
4x-2=0
4x-2+2=0+2
Simplify:
Add the numbers
4x-2+2=0+2
4x=0+2
Add the numbers again
4x=0+2
4x=2
Divide both sides by the same factor
4x=2
4x/4 = 2/4
Simplify:
Cancel terms that are in both the numerator and denominator
4x/4 = 2/4
