11 peopledo not have a a dog.

44 is the total number of people.

What is a Venn-diagram?

'A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationshipsbetween two or more sets of items.'

According to the given problem,

In a Venn-diagram, the number of people in the orange circle owns cats and those in the blue circle owns dogs.

Now, the number of people in the over-lapping area owns both cats and dogs.

Therefore,

11 people own just cats.

6 people own cats as well as dogs.

Total number of cat-owners = ( 11 + 6 )

                                               = 17

15 people own just dogs

6 people own dogs and cats.

Total number of dog-owners = (15 + 6)

                                                = 21

Hence, we can conclude, the number of cat owners being 17 and the number of dog-owners being 21.

Using the completing-the-square method, find the vertex of the function f(x) = –2x2 + 12x + 5 and indicate whether it is a minimum or a maximum and at what point.. .

Answers

f ( x ) = - 2 x² + 12 x + 5 = - 2 ( x² - 6 x ) + 5 = - 2 ( x² - 6 x + 9 - 9 ) + 5 =
- 2 ( x² - 6 x + 9 ) + 18 + 5 = - 2 ( x - 3 )² + 23 
f ( x ) = a ( x - k )² + h ( the vertex form ), k = 3, h = 23. 
a = - 2 < 0, that means the vertex coordinates ( 3, 23 ) represents a maximum.

Answer:

3,23 maximum

Simplify the rational expression. State any restrictions on the variablen^4-10n^2+24/ n^4-9n^2+18

Answers

Answer:

The simplified form is =((n-2)(n+2))/((n-\sqrt3)(n+\sqrt3))

The variable n can not be equals to \pm\sqrt3 as for these value denominator equals to zero which becomes an indeterminate form.

Step-by-step explanation:

we have to simplify the rational expression and state the restrictions on the variable.

(n^4-10n^2+24)/(n^4-9n^2+18)

We can now see that both the numerator and denominator are quadratic trinomials in n^2.\

We split the middle terms as follows;

(n^4-10n^2+24)/(n^4-9n^2+18)=(n^4-6n^2-4n^2+24)/(n^4-3n^2-6n^2+18)

          =(n^2(n^2-6)-4(n^2-6))/(n^2(n^2-3)-6(n^2-3))

          =((n^2-4)(n^2-6))/((n^2-6)(n^2-3))

          =((n-2)(n+2))/((n-\sqrt3)(n+\sqrt3))

which is the simplified form of given expression.

The variable n can not be equals to\pm\sqrt3 as for these value denominator equals to zero which becomes an indeterminate form.

A major concern with Social Security is the possibility that funds will not be available when today’s tax-payers retire to become beneficiaries. According to the Social Security Trustee’s report, an increase of 1.89% in the Social Security payroll tax would keep the account full for the next 75 years. To achieve similar results, benefits would have to be decreased from the current 42% of the ending salary to 29% of the salary.Cindy is relatively new to the workforce. She has 32 years until she can retire. Her current annual salary is $45,000. 1a) Calculate how much Cindy will have to pay in Social Security tax (6.2%) based on this salary. 1b) Calculate how much Cindy will have to pay in Social Security tax if the tax was increased by 1.89%. 2a) Calculate Cindy’s annual Social Security benefit (about 42%) if her salary remains unchanged until she retires (annual average is $45,000). 2b) Calculate Cindy’s annual Social Security benefit if her salary remains unchanged but benefits (based on her annual salary of $45,000) were cut from 42% to 29%. 3) If Cindy were given a choice between the increase in Social Security tax now or the decrease in Social Security benefits when she retires, which would you recommend she choose?
