Could somebody help me solve this please

Answer:

Step-by-step explanation:

Explicit

a_n = a1 * r^(n - 1)

Find r by dividing term (n)/(n - 1)

r = 250 / 50

r = 5

a_n = a * r^(n - 1)

Recursive

a_n = a_(n-1)*r

Try an example

Find a_6

a_6 = 2 * 5^(6 - 1)

a_6 = 2 * 5^5

a_6 = 2 * 3125

a_6 = 6250

recursive

a_n = a_(n - 1)*r

r = 5

n = 6

a_n = 1250 * 5

a_n = 6250

The explicit method looks a whole lot easier, but not for a machine made by Dell and programed by Microsoft. A computer doesn't really mind doing a whole lot of calculations that are repetitive. And in many cases recursive is easier to program and is faster.

Answer:

Step-by-step explanation:

The given sequence is exponential with a first term of a1 = 2 and a common ratio of r = 10/2 = 5.

The explicit equation for an exponential sequence is ...

  a(n) = a(1)×r^(n -1)

So, for the given parameters, the explicit equation is ...

  a(n) = 2×5^(n -1)

__

The recursive equation for any series defines the next term as a function of previous terms. For a geometric sequence the next term is the previous term multiplied by the common ratio. For this sequence, the recursive definition is ...

  a(1) = 2

  a(n) = 5×a(n-1)

Answer:

let's divide the figure in rectangle and triangle.

first we should find the area of triangle.

area of triangle =1/2×base×height

area of triangle=1/2×11cm×7cm

area of triangle=38.5cm²

area of rectangle =length ×width

area of rectangle =11cm×8cm

area of rectangle =88cm²

area of the figure=38.5cm²+88cm²

area of the figure=126.5cm²

Answer:

An=67⋅0.92n

Step-by-step explanation:

The solution is, the formula found in the given question is ,

An=67. 0.92n.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

At 12 p.m., the number of cars in a parking lot is 67.

It is estimated that the number of cars in the parking lot will decrease by 8% each hour.

so, we get,

Given,

at first the number of cars in a parking lot is = 67

now, it is decreasing by 8% each hour.

So, for any hours , let after 'n' hours,

the number will be = 67 * (100 - 8)%×n

                               =67 * 92%×n

                               = 67* 0.92n

Thus, The solution is, the formula found in the given question is ,

An=67. 0.92n.

Answer:

b=5

Step-by-step explanation:

We need to isolate b by itself to find the value of b.

[tex]8b + 12 = 52[/tex]

Subtract 12 from both sides

[tex]8b = 40[/tex]

[tex]b = 5[/tex]

Answer:

the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Given the data in the question;

the distance within 9 miles ⇒ 0 < x > 9

Total costs Q = cx + 4c/( x + 1)

costs should be minimum  ⇒ dQ/dx = 0

⇒ d/dx [ cx + 4c/( x + 1) ] = 0

⇒ ( x + 1)² = 4

take square root of both side

√[ ( x + 1)² ] = √4

x + 1 = 2

x = 2 - 1

x = 1

Therefore, the woman has to live 1 mile from work to minimize the expenses

Answer:

x=7.5

Step-by-step explanation:

To show that the triangles are similar, we simply need to show that all sides are proportionate.

So,  we create a proportion

[tex]\frac{FE}{ZY} =\frac{ED}{XY} = \frac{FD}{XZ}[/tex]

Then we plug in the values

[tex]\frac{6}{12} = \frac{7}{14} = \frac{2x-5}{22}[/tex]

[tex]\frac{6}{12}[/tex] and [tex]\frac{7}{14}[/tex] can be simplified to [tex]\frac{1}{2}[/tex], so that is our ratio of similarity

then we know

[tex]\frac{1}{2} = \frac{2x-5}{22}[/tex]

Now solve

1. Cross multiply

2×(2x-5) = 22

2. Distribute

4x-8 = 22

4x=30

x=7.5

There is your answer, x=7.5

Answer: Its 28 in.^2

Step-by-step explanation: Just did it on I ready

The area of this face is,

⇒ 28 in²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

This face made by three rectangles.

Now,

The area of small rectangle = 4 × 2 = 8 in²

And, The area of large rectangle = 6 × 2 = 12 in²

Hence, The area of this face is,

⇒ 8 + 12 + 12

⇒ 28 in²

Thus, The area of this face is,

⇒ 28 in²

Answer:

  a[n] = (-1/3)^(n -1)

Step-by-step explanation:

The terms have a common ratio of (-1/3)/(1) = -1/3. The general term for a geometric sequence with first term a1 and common ratio r is ...

  a[n] = a[1]×r^(n-1)
