Answer 1

Answer:

[tex]\log\left(\frac{1}{2}\right)+\log\left(\frac{2}{3}\right)+\log\left(\frac{3}{4}\right)+\log\left(\frac{4}{5}\right)+...+\log\left(\frac{98}{99}\right) +\log\left(\frac{99}{100}\right) = \log(\frac{1}{100})[/tex]

Step-by-step explanation:

Given

[tex]\log\left(\frac{1}{2}\right)+\log\left(\frac{2}{3}\right)+\log\left(\frac{3}{4}\right)+\log\left(\frac{4}{5}\right)+...+\log\left(\frac{98}{99}\right) +\log\left(\frac{99}{100}\right)[/tex]

Required

The sum

Using the laws of logarithm, we have:

[tex]\log(a) + \log(b) = \log(ab)[/tex]

Take the first two terms of the series

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3}) = \log(\frac{1}{2} * \frac{2}{3})[/tex]

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3}) = \log(\frac{1}{3})[/tex]

Include the third term

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ \log(\frac{3}{4}) = \log(\frac{1}{3} * \frac{3}{4})[/tex]

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ \log(\frac{3}{4}) = \log(\frac{1}{4})[/tex]

Include the fourth term

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ \log(\frac{3}{4}) + \log(\frac{4}{5}) = \log(\frac{1}{4} *\frac{4}{5})[/tex]

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ \log(\frac{3}{4}) + \log(\frac{4}{5}) = \log(\frac{1}{5})[/tex]

Notice the following pattern

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3}) = \log(\frac{1}{3})[/tex] ---------------- n =2

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ \log(\frac{3}{4}) = \log(\frac{1}{4})[/tex] -------------- n = 3

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ \log(\frac{3}{4}) + \log(\frac{4}{5}) = \log(\frac{1}{5})[/tex] ----------- n = 4

So the sum of n series is:

[tex]\log(\frac{1}{2}) + \log(\frac{2}{3})+ ............ + \log(\frac{n}{n+1}) = \log(\frac{1}{n+1})[/tex]

So, the sum of the series is:

[tex]\log\left(\frac{1}{2}\right)+\log\left(\frac{2}{3}\right)+\log\left(\frac{3}{4}\right)+\log\left(\frac{4}{5}\right)+...+\log\left(\frac{98}{99}\right) +\log\left(\frac{99}{100}\right)[/tex]

[tex]\log\left(\frac{1}{2}\right)+\log\left(\frac{2}{3}\right)+\log\left(\frac{3}{4}\right)+\log\left(\frac{4}{5}\right)+...+\log\left(\frac{98}{99}\right) +\log\left(\frac{99}{100}\right) = \log(\frac{1}{99+1})[/tex]

[tex]\log\left(\frac{1}{2}\right)+\log\left(\frac{2}{3}\right)+\log\left(\frac{3}{4}\right)+\log\left(\frac{4}{5}\right)+...+\log\left(\frac{98}{99}\right) +\log\left(\frac{99}{100}\right) = \log(\frac{1}{100})[/tex]

Step-by-step explanation:

Option-A is accurate because f(x) = 9(x/2)-8 and g(x) = 2(x+8)/9 are the values we get when solving the function.

What is inverse function?

A function receives values, performs certain operations on them, and outputs a result. After acting and concurring with the result, the inverse function switches back to the original function.

The inverse function, which also returns the initial value, returns the result of a function.

this selection. Option-A is the proper choice, so

f(x)=9(x/2)-8

consider the f(x)=y

y=9(x/2)-8

y+8=9(x/2)

(y+8)/9=x/2

2(y+8)/9=x

g(x)=2(x+8)/9

As a result, Option-A, which states that when the function is solved, the output is the inverse function, is correct. Its values are f(x) = 9(x/2)-8 and g(x) = 2(x+8)/9.

The perimeter of a rectangle is 84 cm. If the length is 29 cm write an equation you can use to answer this question

Answers

Answer:

Width = 13

Equation: 2 × 29 + 2W = 84

Step-by-step explanation:

Ace here!

I'm going to assume that we have to find the width. In a rectangle, there are 4 sides and opposite sides are congruent.

Let L represent the length and W represent the width.

Since there are 4 sides, we know that to find the of a rectangle perimeter, we have to do:

L+L+W+W=Perimeter

Let's first simplify this equation by combining like terms:

2L+2W = Perimeter

Now, let's plug in known values:

2(29) + 2W = 84

Divide everything by 2:

29+W=42

Isolate W:

W=42-29

W=13

Keep in mind, I didn't have to divide by 2 at the step that I had. I could've also done this:

2(29) + 2W = 84

Simplify:

58+2W=84

Bring everything to one side:

2W=26

Isolate W by dividing 2:

W=13

£100 is deposited in a bank paying 2.25% simple interest per annum. How much interest will have been paid after 5 years

Answers

Answer:

£11.25

Step-by-step explanation:

I = P * R * T

Where,

I = simple interest

P = principal = £100

R = interest rate = 2.25%

T = Time = 5 years

I = P * R * T

= 100 * 2.25% * 5

= 100 * 2.25/100 * 5

= (100 * 2.25 * 5) / 100

= 1,125/100

= 11.25

I = £11.25

Answers

Answer:

m<K = [tex]146^{o}[/tex]

Step-by-step explanation:

With the given conditions in the question, it would be observed that ΔJKL is an isosceles, since KL ≅ JK. So that JL is the base of the triangle:

m<J ≅ m<L = [tex]17^{o}[/tex] (base angle of an isosceles triangle are equal)

Then;

m<J + m<K + m<L = [tex]180^{o}[/tex] (sum of angles in a triangle)

[tex]17^{o}[/tex] + m<K + [tex]17^{o}[/tex] = [tex]180^{o}[/tex]

m<K + 34 = [tex]180^{o}[/tex]

m<K  = [tex]180^{o}[/tex] - 34

m<K = [tex]146^{o}[/tex]

Thus, with respect to the given question, the measure of angle K is [tex]146^{o}[/tex]. Which is an obtuse angle of the triangle JKL.

[tex]b=\frac{4c-a^{2} }{3}[/tex]

Step-by-step explanation:

First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division

Then, you have [tex]4c=a^{2} +3b[/tex]

Subtract both sides by a squared

DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition

From that you get [tex]4c-a^{2} =3b[/tex]

Finally, divide both sides by 3.

You get  [tex]b=\frac{4c-a^{2} }{3}[/tex]

What is the approximate area of the octagon?

71 ft2
101 ft2
110 ft2
202 ft2

Answers

Answer:

Area of regular octagon is 102.16 ft².

Step-by-step explanation:

Using Formula

Area of regular octagon = 2 a ² ( 1 + √2 )

substitute the values

Area of regular octagon = 2 ( 4.6 ft ) ²( 1 + √2 )

Evaluate the exponent

Area of regular octagon = 2 × 21.16 ft ²( 1 + √2 )

Using distributive property

Area of regular octagon = 42.32 × 1 + 42.32 × √2

multiply, we get

Area of regular octagon = 42.32 + 59.84

Add

Area of regular octagon = aaprox. 102.16 ft ²

Therefore, area of regular octagon is 102.16 ft².

Answers

Answer:

See all the answers  below.

Step-by-step explanation:

by² = d

Jay = 6

ay - cy = d.

cy - b) = y

Option A

by² = d

divide both side by b

y² = d/b

square both sides

y=√d/b

Option B

Jay = 6

Divide both sides by Ja

y= 6/Ja

Option C

ay - cy = d

y(a-c)=d

divide both sides by (a-c)

y= d/(a-c)

Option D

(cy - b) = y

y-cy=-b

y(1-c)=-b

y= -b/(1-c)
