The unit cost decreases the more you buy at once. 1.10/1 = $1.10 you're paying $1.10 per 1. 1.98/2 = $ .99 you're paying $.99 per 1 2.89/3 = $.96 you're paying $.96 per 1. When you buy 9 you're paying less per 1 than you are when you buy 1

Tiffany uses 1/10 of her wages each month to buy company stock. Also she puts 1/20 of her wages in a savings account, and 1/15 i

Novosadov [1.4K]

Answer:

The fraction of Tiffany wages taken out for these purpose is $\dfrac{13}{60}$ .

Step-by-step explanation:

Given as :

Let The wages earn by Tiffany = $x

Let The fraction of Tiffany wages taken out for purpose = $y

Tiffany uses $\dfrac{1}{10}$ of her wages each month to buy company stock.

She puts $\dfrac{1}{20}$ of her wages in a savings account .

She puts $\dfrac{1}{15}$ of her wages into company pension plan

Now,

Total fraction of wages used by Tiffany = fraction used to buy company stock + fraction used in saving account + fraction used in pension plan

Or, y = $\dfrac{1}{10}$ + $\dfrac{1}{20}$ + $\dfrac{1}{15}$

Now taking LCM

Or, y = $\dfrac{12 + 6 + 8}{120}$

Or y = $\dfrac{26}{120}$

Or, y = $\dfrac{13}{60}$

So, The fraction of Tiffany wages taken out for purpose = y = $\dfrac{13}{60}$

Hence, The fraction of Tiffany wages taken out for these purpose is $\dfrac{13}{60}$ . Answer

A sequence is defined by the explicit formula an=3n+4 Which recursive formula represents the same sequence of numbers?

fomenos

Answer:

Option (3)

Step-by-step explanation:

Explicit formula of the sequence is,

$a_n=3^n+4$

From this explicit formula,

First term of the sequence will be,

$a_1=(3^1)+4$

$a_1=7$

Second term of the sequence,

$a_2=(3^2)+4$

$a_2$ = 13

3rd term of the sequence,

$a_{3}=(3^3)+4$

= 31

Sequence formed,

7, 13, 31 ..........

From the given options,

Recursive formula,

$a_n=3a_{n-1}-8$

$a_2=3(a_1)-8$

$a_2=3(7)-8$

$a_2=21-8$ = 13

$a_3=3a_2-8$

$a_3=3(13)-8$

= 39 - 8

= 31

Sequence formed from this recursive formula will be,

7, 13, 31........

Therefore, Option (3) will be the answer.

A soccer ball is kicked from the ground in an arc defined by the function, h(x) = -8x 2 + 64x. At what point does the ball hit t

Strike441 [17]

Answer:

The soccer ball hit the ground at (8, 0)

Solution:

To find at what point the ball hit the ground we make the given function equal to zero.

Here the given function is $h(x)=-8 x^{2}+64 x$

We make h(x) = 0 and try to find the value of x

h(x) = 0

$-8 x^{2}+64 x=0$

-8x (x - 8) = 0

-8x = 0 or (x - 8) = 0

Therefore x = 0 or x = 8

At x= 0 the ball was not kicked. Now we try to find the value of the function by substituting x = 8 in the given function and find the value of the function.

$h(8)=-8\left(8^{2}\right)+64(8)$

=-512 + 512 = 0

Thus the ball hit the ground at (8,0).
