Answer:

[tex] \pm \sqrt{13} [/tex]

Step-by-step explanation:

[tex] \bigg(a + \frac{1}{a} \bigg)^{2} = {a}^{2} + \frac{1}{ {a}^{2} } + 2 \times a \times \frac{1}{a} \\ \\ \bigg(a + \frac{1}{a} \bigg)^{2} = 11 + 2 \\ \\ \bigg(a + \frac{1}{a} \bigg)^{2} = 13 \\ \\ \bigg(a + \frac{1}{a} \bigg) = \pm \sqrt{13} [/tex]

Answer:

Step-by-step explanation:

5x - 8x - 22 = 14

-3x - 22 = 14

-3x = 36

x = -12

Answer:

x = -12

Step-by-step explanation:

5x - 2(4x+11) = 14

5x - 2*4x -2*11 = 14

5x - 8x - 22 = 14

-3x = 14 + 22

-3x = 36

x = 36/-3

x = -12

Check:

5*-12 -2(4*-12 + 11) = 14

-60 -2(-48+11) = 14

-60 -2(-37) = 14

-60 + 74 = 14

Distance = sqrt(x1-x2^2 + y1-y2^2)

Distance = sqrt((-1-11)^2 +(6-1)^2)

Distance = sqrt(12^2 + 5^2)

Distance = sqrt(144 + 25)

Distance = sqrt(169)

Distance = 13

Answer: 75 < x < 125.

Step-by-step explanation:

Let x be the amount of money in your wallet.  

The phrase "100 dollars give or take 25" means wallet can have money between (100-25) dollars and (100+25) dollars.

i.e. 100-25 < x < 100+25

⇒ 75 < x < 125.

That means the amount of money in your wallet lies between 75 dollars and 125 dollars.

Hence, the inequality to describe the amount of money in your wallet is 75 < x < 125.

Answer:

AC = 25

Step-by-step explanation:

Since B is on the segment AC, then

AC = AB + BC, substitute values

5x = 2x +10 + x , that is

5x = 3x + 10 ( subtract 3x from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Thus

AC = 5x = 5(5) = 25

Answer:

Domain of f(x) = 2/7x - 2: (-∞, ∞)

Range of f(x) = 2/7x - 2: (-∞, ∞)

Domain of f(x) = |x + 3| - 1: (-∞, ∞)

Range of f(x) = |x + 3| - 1: [-1, ∞)

Domain of f(x) = -5x + 4: (-∞, ∞)

Range of f(x) = -5x + 4: (-∞, ∞)

Step-by-step explanation:

We can use a graphing calculator to find the graphs.

Domain is the set of all x-values that can be inputted into function x.

Range is the set of all y-values that can be outputted from function x.

Answer:

n/3 - 18

Step-by-step explanation:

"quotient of a number and 3" is n/3, and so

"18 less than the quotient of a number and 3" as an expression is:

   n/3 - 18

Given :

Let sin(45°)=0.7071.

To Find :

The angle measure (μ), in degrees for cos(μ)=−0.7071 and value equivalent to 360n + , where n is an integer .

Solution :

We know , value of sin x and cos x is same at x = 45° .

Now , cos (-x) = cos(90°+x)

Therefore , μ in given question is :

μ =90°+45°

μ=135°

So , for angle of type 360°n + :

μ = 360°n + 135° .

Hence , this is the required solution .

Answer:

x-5

Step-by-step explanation:

"difference" means subtraction. since there isn't a specific number given then we can use x. "and" indicates where the symbols goes.

32.50 - (7.50*2) = 17.50

17.50 / 2.50 = 7

A. y = 1/3 (-3) - 3 = - 6

B. y = 2(-3)^2 - 3(-3) - 2

= 2(9) - 3(-3) - 2

= 18 + 9 - 2

= 25

C. 2(-3) - 5y =4

- 6 - 4 = 5y

y = - 2

Answer:

A = -6

B = 25

C = 2

Step-by-step explanation:

-3*1/3 = -1, and -1-5=-6

2(-3)^2=2(9)=18   -3*-3=9    18+9=27    27-2=25

for the last rewrite the equation

2x-4=5y

-6-4=-10

-10=5y

y=-2

Step-by-step explanation:

Answer:

5.8 , which approximately is 6 weeks.

Step-by-step explanation:

the first method is the short one since u just have to double the 85 then divide to 1000.

1000 ÷ ( 85 × 2)

1000 ÷ 170 = 5.882,,,,,. round off to whole number to get 6.

the second method is the addition method.

we start by 85 then keep doubling 85 for every week........inshort.......we add 170 to each weeks number to get the number of followers for the following week.

85 ⇒ 170 ⇒ 340 ⇒ 510 ⇒ 680 ⇒ 850 ⇒ 1020.

     1st      2nd      3rd     4th      5th         6th     week.

u notice that we add (85×2), 170, to get the following week's number of followers..

in 5 weeks..... the number of followers is yet to get to 1000.

when u divide, u get 5.8.....,and it is not logic to say 5.8823....weeks

since she reaches 1000 followers in the 6th week.......though there is an addition,,,, it is the most appropriate answer.

It will take [tex]6[/tex] week to reach [tex]1000[/tex] followers.

First, we are using two step to find the answers.

Division:

   By given, A artist has [tex]85[/tex] followers.

Every week  the no. of. followers is doubled .

Now, find how many week the artist reach [tex]1000[/tex] followers.

Since week followers is doubled,

So ,[tex]85*2[/tex]

Thus,

 [tex]1000\div(85*2)\\\\=1000\div170\\\\=5.883[/tex]

Which is not possible .

Then, it take [tex]6[/tex]  week to reach the  [tex]1000[/tex] followers.

Addition:

    By given, A artist has [tex]85[/tex] followers.

Every week  the no. of. followers is doubled .

To find how many week the artist reach [tex]1000[/tex] followers.

Now, the first week has [tex]85[/tex] followers.

[tex]85[/tex] followers doubled.

[tex]85+85=170[/tex] followers doubled in every week .

Then,

Hence, the artist reach [tex]1000[/tex] followers in mid week of [tex]5[/tex] to [tex]6[/tex] week .

so, it approximately take  [tex]5.88[/tex] week to reach [tex]1000[/tex] followers but which is impossible to take decimal in week .

Thus, the artist take [tex]6[/tex] week to reach the [tex]1000[/tex] followers.

I just took the test and I got a 100. :)

Given :

An adults heart beats about 2100 times every 30 minutes.

A baby beats about 2600 times every 20 minutes.

To Find :

How many more heart beat baby have than adult in 60 min .

Solution :

Now , total number of heart beats of adult in 60 min , [tex]T_a=2100\times 2=4200[/tex]

Also , total number of heart beats of adult in 60 min , [tex]T_b=2600\times 3=7800[/tex]

Difference between them , [tex]7800-4200=3600[/tex] beats .

So , baby have 3600 more heart beats than adult .

Hence , this the required solution .

Answer:

the range= {-16, -6, 0, 2}

Step-by-step explanation:

domain={0,1,2,3}

g(x)= -2x^{2} + 2

g(0)= -2(0)^{2} + 2 =2

g(1)= -2(1)^{2} + 2 =0

g(2)= -2(2)^{2} + 2= -6

g(3)= -2(3)^{2}+ 2= -16

the range = {-16, -6, 0, 2}
