Which Formula Can Be Used To Find The Nth Term Of A Geometric Sequence Where The Fifth Term Is 1/6 And

Answers

Answer 1

Answer:

[tex] a_n = 16(\frac{1}{4})^{n - 1} [/tex]

Step-by-step explanation:

Given:

Fifth term of a geometric sequence = [tex] \frac{1}{16} [/tex]

Common ratio (r) = ¼

Required:

Formula for the nth term of the geometric sequence

Solution:

Step 1: find the first term of the sequence

Formula for nth term of a geometric sequence = [tex] ar^{n - 1} [/tex], where:

a = first term

r = common ratio = ¼

Thus, we are given the 5th term to be ¹/16, so n here = 5.

Input all these values into the formula to find a, the first term.

[tex] \frac{1}{16} = a*\frac{1}{4}^{5 - 1} [/tex]

[tex] \frac{1}{16} = a*\frac{1}{4}^{4} [/tex]

[tex] \frac{1}{16} = a*\frac{1}{256} [/tex]

[tex] \frac{1}{16} = \frac{a}{256} [/tex]

Cross multiply

[tex] 1*256 = a*16 [/tex]

Divide both sides by 16

[tex] \frac{256}{16} = \frac{16a}{16} [/tex]

[tex] 16 = a [/tex]

[tex] a = 16 [/tex]

Step 2: input the value of a and r to find the nth term formula of the sequence

nth term = [tex] ar^{n - 1} [/tex]

nth term = [tex] 16*\frac{1}{4}^{n - 1} [/tex]

[tex] a_n = 16(\frac{1}{4})^{n - 1} [/tex]

Answer:

y = 5

Step-by-step explanation:

14y + 36 = 106. subtract 36 from both sides, so now the equation is 14y = 70 because 36 is cancelled out. now divide both 14y and 70 by 14, which leaves you with y = 5

Find x if AB = 9, BC = 2x - 5,
and AC = x + 9

Answers

Answer:

x = 5

Step-by-step explanation:

Using the fact that line segments AB and BC are parts of the whole line segment AC, we can write the following equation:

AB + BC = AC

Now, using the given values, we can substitute in for the equation and solve for x:

AB + BC = AC

9 + 2x - 5 = x + 9

2x + 4 = x + 9

x = 5

Thus, we have found that for these sets of equations for these line segments, our value for x should be 5.

Cheers.

Answer:

x=5

Step-by-step explanation:

AB + BC = AC

9+ 2x-5 = x+9

Combine like terms

2x+4 = x+9

Subtract x from each side

2x+4-x = x+9-x

x+4 = 9

Subtract 4 from each side

x+4-4 = 9-4

x=5

If measuring the volume of a liquid is in milliliters (mL), what are the units if I wanted to measure the volume of a solid (like a cube)?

Answers

Answer:

cm3,m3 etc...

Step-by-step explanation:

SInce 3D objects are solids and are different than 2D measurements,we use the measurement Centimeters "Cubed".You may ask what do you multiply to get the volume of a solid?Well the way i was taught was Length * Width * Height.(Stars mean Multiplication)

e.g. Lets say you have a cube,the length is 3,width is 3,height is 4 this is how it looks like

V=L x W x H

=3 x 3 x 4

=36 cm3

That's how Volume is calculated

What is the length of Line segment A B? Round to the nearest tenth. Triangle A B C is shown. Angle A C B is a right angle and angle C A B is 75 degrees. The length of C A is 10 meters and the length of hypotenuse A B is x. 9.7 m 10.4 m 37.3 m 38.6 m

Answers

Answer:

D.) 38.6 m

Step-by-step explanation:

Use the cosine ratio:

[tex]cosine=\frac{adjacent}{hypotenuse}[/tex]

Because we are given the measure of an angle and the length next to it (adjacent), and we need to find the hypotenuse (the hypotenuse is NEVER considered the adjacent side). Insert the values:

[tex]cos75=\frac{10}{x}[/tex]

Now isolate the variable. Multiply both sides by x:

[tex]x(cos75)=x(\frac{10}{x} )[/tex]

The x's on the right side cancel each other out. Simplify:

[tex]x*cos75=10[/tex]

Now divide both sides by cos75°:

[tex]\frac{x*cos75}{cos75} =\frac{10}{cos75}[/tex]

The cos75° on the left side cancels each other. Simplify:

[tex]x=\frac{10}{cos75}[/tex]

Insert this value into a calculator to simplify the value of x:

[tex]x=38.6[/tex]

The hypotenuse is 38.6 m.

A geometric sequence is shown on the graph below. What is the formula for the nth term of the sequence?

Answers

Answer:

aₙ = 40*(1/2)ⁿ⁻¹

Step-by-step explanation:

As per graph we have:

a₁ = 40, a₂ = 20, a₃ = 10, a₄ = 5, a₅ = 2.5

So the first term is 40 and common ratio is

20/40= 10/20 = 5/10 = 2.5/5 = 1/2

Formula for nth term is:

aₙ = a₁rⁿ⁻¹aₙ = 40*(1/2)ⁿ⁻¹

Express the pair of fraction using the least common denominator of the two 3/8,7/10

Answers

Answer:

Step-by-step explanation:

3/8 x 5/5 = 15/40

7/10 x 4/4 = 28/40

15/40, 28/40

The least common denominator of the two pairs of fractions is 15/40 are 28/40. which is the correct answer would be an option (A).

What is LCD?

The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

We have to determine the least common denominator of the two pairs of fractions.

The fractions are 3/8, and 7/10

⇒ 3/8

Multiply by 5/5 in the fraction,

⇒ 3/8 × 5/5 = 15/40

⇒ 7/10

Multiply by 4/4 in the fraction,

⇒ 7/10 × 4/4 = 28/40

Therefore, the least common denominator of the two pairs of fractions is 15/40 are 28/40

The pizza has an area of 78.5 in². What is the minimum width of a placemat that can be placed underneath it so that the pizza does not touch the table? Use 3.14 for pi. someone pls help me

Answers

Answer:

10 inches

Step-by-step explanation:

Given:

Area of pizza = 78.5 in²

To find:

Minimum width of placement to be placed underneath the pizza so that it does not touch the table?

Solution:

We are actually required to find out the diameter of the circular pizza here.

That will be the minimum width of the placement to be placed underneath the pizza so that pizza does not touch the table.

Let us have a look at the formula of area of a circle.

[tex]A=\pi r^2[/tex]

Where [tex]r[/tex] is the radius of the circle

We are given that

[tex]A = 78.5\ in^2[/tex]

[tex]\Rightarrow 78.5 = \pi r^2\\\Rightarrow 78.5 = 3.14\times r^2\\\Rightarrow \dfrac{78.5}{3.14} = r^2\\\Rightarrow r^2=25\\\Rightarrow r =5\ in[/tex]

Now, we know that the diameter is given as twice of the radius.

So, minimum width required = Diameter = 2 [tex]\times[/tex] 5 = 10 inches
