Answer: a₉ = 327,680

Step-by-step explanation:

This seems to be a geometric sequence.

The recursive relation for this type of sequence is:

aₙ = aₙ₋₁*r

Where r is a constant.

Then we also have:

aₙ/aₙ₋₁ = r.

then we can find the value of r if we take the quotient of different consecutive terms, for example, the quotient of the second and firs term is:

r = 20/5 = 4

And the quotient between the third and second term is:

r = 80/20 = 4

Then we can conclude that r  = 4.

And also, the n-th term of this sequence can be written as:

aₙ = a₁*r^(n - 1)

such that:

a₁ = 5

r = 4

Then the n-th term of this sequence is:

aₙ = 5*(4)^(n - 1)

Then the term a₉ can be found if we just replace n by 9 in the above equation:

a₉ = 5*(4)^(9 - 1) = 5*(4)^(8) = 327,580

Answer: .10d+.25q<_ 4

Step-by-step explanation:

d= dimes and q = quarters

dimes are worth .10 and quarters are worth .25

The inequality for the given situation is

0.1d + 0.251 ≤ 4

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

10 dimes = 1 dollar

1 dime = 0.1 dollar

4 quarters = 1 dollar

1 quarter = 0.25 dollar

Now,

The maximum amount is $4.

So,

0.1d + 0.251 ≤ 4

Thus,

The inequality is 0.1d + 0.251 ≤ 4.

The gazebo with the longest side length is the heptagon.

A heptagon is a polygon with 7 sides. It has 7 edges and vertices.

The length of the side of a heptagon = (area of the heptagon x 2) / (number of sides x length of the apothem)

= (623.5 x 2) / (7 x 13.6)

= 1247 / 95.2

= 13.1 feet

A octagon is a polygon with 8 sides. It has 8 edges and vertices. The sum of internal angles in 135 degrees.

The length of the side of a octagon = (area of the octagon x 2) / (number of sides x length of the apothem)

= (517.8 x 2) / (12.5 x 8)

= 1035.6 / 100

= 10.356 feet

Answer: B. [tex]\dfrac1{45}\times5=\dfrac19[/tex]

Step-by-step explanation:

We know that,

[tex]\dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}[/tex]

Then, [tex]\dfrac19\div 5[/tex] [tex]=\dfrac19\times\dfrac15[/tex]

[tex]=\dfrac1{45}[/tex]

i.e.

[tex]\dfrac19\div 5=\dfrac{1}{45}\\\\\Rightarrow\ \dfrac1{45}\times5=\dfrac19 \ \ \ \text{[Multiply 5 on both sides]}[/tex]

Therefore, the multiplication equation is related to the division equation [tex]\dfrac1{45}\times5=\dfrac19[/tex]

Hence, the correct option is B. [tex]\dfrac1{45}\times5=\dfrac19[/tex]

Answer:

UD = 20

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the external part and the entire secant, that is

12² = 7.2(7.2 + CD)

144 = 7.2² + 7.2CD

144 = 51.84 + 7.2CD ( subtract 51.84 from both sides )

92.16 = 7.2CD ( divide both sides by CD )

12.8 = CD

Thus

UD = UC + CD = 7.2 + 12.8 = 20

Answer:

26x2,

52xπ

Step-by-step explanation:

The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let 'r' be the radius of the circle. The circumference of the circle will be

C = 2πr units

The radius of the semicircle is given as,

r = 26 cm

Then the circumference of the semicircle is half of the circle. Then we have

C = 1/2 x 2πr

C = πr

At r = 26 cm, then we have

C = 3.14 x 26

C = 81.64 cm

The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.

Sum of 5b and 7 = 5b + 7

Equation;

5b + 7 = 3

Answer:

b) Use the distributive property to get 4c-12=8

c) Divide both sides by 4 to get c-3=2

Step-by-step explanation:

Solve the equation 4(c-3)=8

What are two ways to start solving this equation?

We are given the Equation

4(c - 3) = 8

The two ways to start solving this Equation is given as:

1. 4(c - 3) = 8

We expand the brackets, using Distributive property

4c - 12 = 8

Or

2. 4(c - 3) = 8

Divide both sides by 4

4(c - 3)/4 = 8/4

c - 3 = 2

Therefore, options b and c is correct

Answer:

6

Step-by-step explanation:

you want to create two equations for each situation so if v=number of students that can fit in a van and c=number of students that can fit in a car then you can create the equations 3v+1c=22 and 2v+4c=28

then you want to make both equations equal to c

so for the first one you subtract both sides by 3v and you get c= -3v+22

and for the second one you subtract 2v from both sides and end up with 4c=-2v+28 and then divide both sides by 4 leaving you with c= -1/2v+7

then you make both of those equations equal to each other and solve for v

so -3v+22= -1/2v+7 and you end up with v=6

therefore, each van can hold 6 students

Answer:

C:  y = 2(x - 4) - 2

Step-by-step explanation:

The vertex formula of a quadratic is y - k = m(x - h).  

Here the vertex is at (4, -2), and so we now have y + 2 = a(x - 4).

Find a:  letting y = 0 and x = 5, we get 0 + 2 = a(5 - 4), which means a  = 2.

The desired equation is C:  y = 2(x - 4) - 2
