Find the sum to infinity of the infinite G.P.
1-½+¼........​

Answers

Answer 1

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The sum to infinity of a GP is

[tex]S_{infinity}[/tex] = [tex]\frac{a}{1-r}[/tex] ; | r | < 1

where a is the first term and r the common ratio

Here a = 1 and r = - [tex]\frac{1}{2}[/tex] ÷ 1 = - [tex]\frac{1}{2}[/tex] , thus

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

Answer 2

Answer:

2/3

Step-by-step explanation:

1-1/2+1/4.....

[tex]r=\frac{\frac{-1}{2} }{1} =-\frac{1}{2} \\if~|r|<1,then~s_{\infty}=\frac{a}{1-r} ,a=first~term.\\s_{\infty}=\frac{1}{1-(\frac{-1}{2}) } =\frac{1}{1+\frac{1}{2} } =\frac{1}{\frac{3}{2} } =\frac{2}{3}[/tex]

z1 =3+4i and z2=4+3i then what is the relation of z1 and z2?​

Answers

The modulus of the functions z₁ and z₂ will be same.

What is Modulus function?

The modulus function is the absolute value of a positive or negative number.

Given that;

The functions are,

⇒ z₁ = 3 + 4i

⇒ z₂ = 4 + 3i

Now,

Since, The functions are,

⇒ z₁ = 3 + 4i

⇒ z₂ = 4 + 3i

Hence, The modulus of the functions are find as;

⇒ | z₁ | = √ 3² + 4²

⇒ | z₁ | = √ 9 + 16

⇒ | z₁ | = √ 25

⇒ | z₁ | = 5

And, | z₂ | = 4 + 3i

⇒ | z₂ | = √ 4² + 3²

⇒ | z₂ | = √ 16 + 9

⇒ | z₂ | = √ 25

⇒ | z₂ | = 5

Thus, The modulus of the functions z₁ and z₂ will be same.

Marcus works at a coffee shop. He earns $10.25 each hour. Use marcus's time sheet for the week to answer the questions.


3. Marcus was offered a position which pays a salary of $150 every week and a 25 cent commission for each ice cream cone he sell. Marcus sells an average of 125 ice cream cones each week. How much will Marcus make in the new position. Compare this to how much he made for a week at his current job. She he take the new position? Why or why not?

Answers

Answer:

Should he take the new position?

He shouldn't not take the new position

Why or why not?

This is because he makes a lot more at his old job than his new position

Step-by-step explanation:

Please find attached to this answer, Marcus worksheet at for a week at the coffee shop

For his first job

Marcus works at a coffee shop. He earns $10.25 each hour.

Let the number of hour is = x

The equation is given as:

$10.25x

For a week

October 11, He worked from 5:45 - 12.00pm = 6 hours 15 mins = $61.5

For his

October 12, He worked from 5:45 - 1:00pm = 7 hours 15 mins = 71.75

October. 13

3. Marcus was offered a position which pays a salary of $150 every week and a 25 cent commission for each ice cream cone he sell.

Let the number of ice cream sells be equal to x

25cent = $0.25

$150 + $0.25× x

$150 + $0.25x

Marcus sells an average of 125 ice cream cones each week.

The amount Marcus makes in his new position in 1 week =

$150 + $0.25 × 125

= $150 + $31.25

= $181.25

Compare this to how much he made for a week at his current job.

Marcy makes more at his old job than his new position.

Should he take the new position?

He shouldn't not take the new position

Why or why not?

This is because he makes a lot more at his old job than his new position

What is the value of the unknown number, h?

Answers

Answer:

h=3

Step-by-step explanation:

you want h alone on one side of the equation and you must do the same to both sides, 4-4 cancels out the 4, 7-4=3 so h is greater than or equal to 3, next, 1-1 cancels out 1, 3-1=2 so h>2, therefore h=3

A shipping company specializing in big items, like couches and cars, charges a $99 handling fee plus $0.32 per pound. Write an equation representing the total cost to ship an item based on its weight.

Answers

Answer:

$0.32x + $99 = c (cost)

Step-by-step explanation:

First, the problem tells you that the company is charging $0.32 per pound. The phrase "per pound" tells us that the 32 cents is not a fixed amount, so it must be paired with a variable like x since any item could easily weigh more than one pound when shipping.

Next, the problem says there's a handling fee of $99 for each purchase. This is a fixed amount, meaning there will be no variable with it since this fee will always just cost $99. This fee will be added to the $0.32x, so it can be represented anywhere in the equation like "+ $99" or "$99 +".

Finally, just write each term as an equation and you're all set! There can be multiple ways to write the equation. For example, $0.32x + $99 = c is correct, but $99 + $0.32x = c is also correct!

Answers

Answer:

5.9 minutes

Step-by-step explanation:

85% of 50 items is gone in 5 minutes

42.5 items = 5 minutes

50 items = x minutes

42.5 items × x minutes = 50 items × 5 minutes

x = 50 items × 5 minutes/42.5 items

x = 5.8823529412 minutes

Jill is baking a pumpkin pie. The recipe calls for 4 ⅓ cups of flour, but Jill has 2 ⅘ cups. How many cups of flour does Jill need?

Answers

Answer:

1 8/15

Step-by-step explanation:

We need to equal the denominators. We have 1/3 and 4/5, and we need to make the bottom numbers equal to each other. The closest common factor is 15 (which we got from 3 x 5). With the denominators solved, we now need to equal out the top numbers, or the numerators. 1 x 5 gives us 5/15, and 4 x 3 gives us 12/15. Then, we need to apply these to each variable. This gives us Jill's 2 12/15th cups of flour, and the recipe's call for 4 5/15 cups. We then subtract these from each other, giving us 1 8/15 cups of flour is needed from Jill.

A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet away from the player. The height $y$y​ (in feet) of a second hockey puck is modeled by $y=x\left(0.15-0.001x\right)$y=x(0.15−0.001x)​ , where x$x$x​ is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.

Answers

Answer:

The maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels further  

Also the distance of the maximum height of first pluck from the player is less than the distance of the second pluck from the player hence the second pluck travels further

Step-by-step explanation:

From the question we are told that

  The maximum height of the first pluck is  [tex]h_1 = 3 \ ft[/tex]

   The height of the second height is mathematically represented as

              [tex]$y=x\left(0.15-0.001x\right)[/tex]

=>           [tex]y=0.15x -0.001x^2[/tex]

Generally at maximum height  [tex]y' = 0[/tex]

So

      [tex]y'=0.15 -0.002 x = 0[/tex]

=>    [tex]x =  75 \  ft [/tex]

Here 75 ft is the horizontal distance the second pluck traveled at maximum height

   So the maximum height of the second pluck is mathematically represented as

       [tex]y=0.15(75) -0.001(75)^2[/tex]

=>     [tex]y=  5.625 \  ft [/tex]  

So comparing the maximum height  of the first and the second pluck we see that the maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels father
