Help me find the range of this function please

Answers

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

[tex]f(x)=-2x-18[/tex]

[tex]f(-8)=-2(-8)-18[/tex]

[tex]f(-8)=16-18[/tex]

[tex]f(-8)=-2[/tex]

The first value of the range of the function is -2

- For x = -2

[tex]f(x)=-2x-18[/tex]

[tex]f(-2)=-2(-2)-18[/tex]

[tex]f(-2)=4-18[/tex]

[tex]f(-2)=-14[/tex]

The second value of the range is -14

- For x = 4

[tex]f(x)=-2x-18[/tex]

[tex]f(4)=-2(4)-18[/tex]

[tex]f(4)=-8-18[/tex]

[tex]f(4)=-26[/tex]

Th third values of the range is -26

- For x = 16

[tex]f(x)=-2x-18[/tex]

[tex]f(16)=-2(16)-18[/tex]

[tex]f(16)=-32-18[/tex]

[tex]f(16)=-50[/tex]

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}

Carlos Can choose from a beef or turkey burger and from a wheat or white roll. How many different burgers can he make

Answers

The correct option is C.

Carlos can make 4 different burgers by choosing between beef or turkey and wheat or white roll.

To calculate the number of different burgers Carlos can make, we'll use the fundamental principle of counting.

Step 1: Determine the number of options for the type of burger. Carlos can choose either beef or turkey, so there are 2 options.

Step 2: Determine the number of options for the type of roll. Carlos can choose either wheat or white, so there are 2 options.

Step 3: Multiply the number of options for each step together to find the total number of combinations.

Number of burger options × Number of roll options = Total combinations

2 options for type of burger × 2 options for type of roll = 4 total combinations

So, Carlos can make 4 different burgers.

the radius of the circle x^2+y^2 +px+6y-3=0 is 4. find the possible values of p​

Answers

Here, the given equation is,

x^2+y^2+px+6y-3=0

By copairing it with x^2+y^2+2gx+2fy+c=0, we get,

2g=p or, g=p/2

2f=6 or, f=3

c=-3

now the radius is,

r^2=g^2+f^2-c

or, 4^2=(p/2)^2 +3^2 -(-3)

or, 16= p^2/4 +9+3

or, 16-9-3=p^2/4

or p^2/4=4

or, p^2=4×4

or p^2=4^2

or p=4

therefore the rewuired value of p is 4.

Answer:

Possible values are 4 and -4.

Step-by-step explanation:

First complete the square on the x and y terms:

x^2 + y^2 + px + 6y - 3 = 0

(x + 0.5p)^2 - 0.25p^2 + (y + 3)^2 - 9 - 3 = 0

(x + 0.5p)^2 + (y + 3)^2 = 12 + 0.25p^2

This is the standard form of the equation of the circle where the right side = radius^2 so we can write:

12 + 0.25p^2 = 4^2

0.25p^2 = 16 - 12 = 4

Taking square roots:-

0.5p = +/- 2

p = 2 / 0.5 , -2 / 0.5

p = 4, -4.

Three friends went to the peach orchards in the country. There they can pick as many peaches as they want, but the owner gets p amount of peaches from each person who picks peaches. The three friends pick these amounts:

2p, 4p + 3, and 3p + 2.

After giving the owner his peaches, what did the three friends take home?

Answers

Answer:

The three friends took 6p + 5 peaches home

Explanation:

We are given that the three friends picked 2p, 4p+3 and 3p+2 peaches

This means that:

Total picked = 2p + 4p + 3 + 3p + 2 = 9p+5 peaches

Now, we know that the owner will take p peaches from each of the three friends

This means that:

Amount taken by owner = 3p peaches

Finally, to get the amount that the three friends will take home, we subtract the amount that the owner will take from the total amount they picked

This means that:

Number of peaches they took home = total picked - amount taken by owner

Number of peaches they took home = 9p + 5 - 3p

Number of peaches they took home = 6p + 5 peaches

Answers

Hello!

The answers are:

- The quantity that represents the initial number of bacteria is 64.

- The quantity that represents the rate at which the number of bacteria is increasing is (1+0.12) or 1.12 which means the growth rate percentage for the bacteria is 0.12 or (0.12*100), it will be 12%.

Why?

To solve the problem, and complete the statements, we need to remember the form of the exponential growth.

The exponential growth formula is given by the following formula:

[tex]P(t)=StartAmount(1+PercentageRate)^{t}[/tex]

Where,

Start Amount, is the starting population or amount.

(1+Percentage Rate), is the increasing rate

Percentage Rate, is the growth rate percentage.

t, is the time elapsed.

Now, we are given the following expression:

[tex]P(3)=64(1.12)^{3}[/tex]

Which can be rewrited as:

[tex]P(3)=64(1+0.12)^{3}[/tex]

So, we have that:

- The quantity that represents the initial number of bacteria is 64.

- The quantity that represents the rate at which the number of bacteria is increasing is (1+0.12) or 1.12 which means the growth rate percentage for the bacteria is 0.12 or (0.12*100), it will be 12%.

At a particular restaurant, each slider has 250 calories and each chicken wing has 60 calories. A combination meal with sliders and chicken wings has a total of 12 sliders and chicken wings altogether and contains 1100 calories. Determine the number of sliders in the combination meal and the number of chicken wings in the combination meal.

Answers

Final answer:

To find the number of sliders and chicken wings in the combination meal, set up a system of equations and solve. There are 2 sliders and 10 chicken wings in the combination meal.

Explanation:

In order to find the number of sliders and chicken wings in the combination meal, we can set up a system of equations. Let's assume that the number of sliders is 's' and the number of chicken wings is 'c'. We know that each slider has 250 calories and each chicken wing has 60 calories. The total number of sliders and chicken wings in the combination meal is 12, so we have the equation s + c = 12.

We also know that the total number of calories in the combination meal is 1100. Since each slider has 250 calories and each chicken wing has 60 calories, we can write the equation 250s + 60c = 1100.

Now we can solve this system of equations to find the values of 's' and 'c'.

Multiplying the first equation by 60, we get 60s + 60c = 720. Subtracting this equation from the second equation, we get 250s - 60s = 1100 - 720, which simplifies to 190s = 380. Dividing both sides by 190, we find that s = 2.

Substituting this value back into the first equation, we have 2 + c = 12. Solving for 'c', we find that c = 10.

Therefore, there are 2 sliders and 10 chicken wings in the combination meal.

The length of a rectangle is 5 inches longer than the width. The perimeter of the rectangle is 40 inches. What is the width of the rectangle, in inches?

Answers

Answer:

W = 7.5 in

Step-by-step explanation:

We'll use the formula for the perimeter of a rectangle:  P = 2W + 2L.

Here, L = W + 5, so P = 2W + 2L becomes:

P = 2W + 2(W + 5), and this equals 40 in.

Thus we have the equation in W (the desired variable) as follows:

2W + 2(W + 5) = 40 in, or 4W + 10 = 40.

Then 4W = 30, and W = 7.5 in.

Based on the perimeter of this rectangle, the width is 7.5 inches.

The perimeter of a rectangle is calculated by:

= Length + Width + Length + Width

Assuming the width is denoted by x, the length would be:

Length = 5 + Width

Length = 5 + x

The perimeter is given so we can solve for the width:

Length + Width + Length + Width  = Perimeter

5 + x + x + 5 + x + x = 40

10 + 4x = 40

4x = 40 - 10

x = 30/4

x = 7.5 inches

In conclusion, the width is 7.5 inches.

i think its A if it isnt im sorry

Step-by-step explanation:

Answer:

The second option :: V = [tex](25-2x)(20-2x)x[/tex] is correct.

Step-by-step explanation:

The vertical side was 25 inches before cutting out the corners.  

The horizontal side was 20 inches before cutting out the corners.

So now, if you fold all of the corner up, you get a box that has a height of "x".  

The sides are now missing a length of x from each end.  

So the longer edges of the box are now [tex](25-2x)[/tex] inches

The shorter edges of the box are now [tex](20-2x)[/tex] inches

The volume of a box is given by V = length x width x height

So, here the volume becomes:

V = [tex](25-2x)(20-2x)x[/tex] cubic inches.

Answer: Hello there!

The system of equation given is:

y = x^2-4

y = -2x-5

And we want to solve this system:

the first step we can do is replace y in the first equation by the given in the second equation:

y = x^2-4 = -2x - 5

now we can solve it for x:

x^2-4 +2x + 5 = 0

x^2 +2x + 1 = 0

and now we can use the cuadratic equation forumla:

this is, if we have a function of the form:

ax^2 + bx + c = 0

the solutions are:

[tex]x = \frac{-b +/- \sqrt{b^2 -4ac} }{2a}[/tex]

in our equation we have a=1, b = 2 and c= 1

we replace it in the formula given, and we obtain:

[tex]x = \frac{-2 +/- \sqrt{2^2 -4*(1)} }{2} = \frac{-2 +/- \sqrt{4 - 4} }{2} = -2/2 = -1[/tex]

Now we got the value of x, and we could replace it in one of the equations and get the value of y:

y = -2x-5

y = -2*(-1) - 5 = 2 -5 = -3

then the pair is (-1, -3)

and the correct option is D.

The surface area of a regular pyramid with a square base which has a slant height of five units and base side lengths of nine units is:

Answers

Answer:

171 sq units.

Step-by-step explanation:

Since you don't specify you want a the side surface area only, we'll calculate both.

First, the base...

We have a square with a side of 9 units.

Area of the base is then 9 x 9 = 81 sq units.

For the sides, we have 4 triangles with a base of 9 and a height of 5 units.

The area of a triangle is calculated with A = (b * h)/2

So, each of the sides of the pyramid has an area of:

A = (9 * 5) / 2 = 22.5 sq units

There are four sides, so total lateral area: 4 * 22.5 = 90 sq units.

Total area: 81 + 90 = 171 sq units.

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 16 is the square of 4

Check :  x2  is the square of  x1

Factorization is :       (x + 4)  •  (x - 4)

Polynomial Long Division :

2.3    Polynomial Long Division

Dividing :  x + 4

                             ("Dividend")

By         :    x + 3    ("Divisor")

dividend     x  +  4

- divisor  * x0     x  +  3

remainder         1

Quotient :  1  

Remainder :  1  

Equation at the end of step  2  :

 (((x2)+8x)+15) (x+4)•(x-4)

 ——————————————•———————————

     (x-4)        2•(x+3)  

Step  3  :

           x2 + 8x + 15

Simplify   ————————————

              x - 4    

Trying to factor by splitting the middle term

3.1     Factoring  x2 + 8x + 15

The first term is,  x2  its coefficient is  1 .

The middle term is,  +8x  its coefficient is  8 .

The last term, "the constant", is  +15

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

     -3    +    -5    =    -8

     -1    +    -15    =    -16

     1    +    15    =    16

     3    +    5    =    8    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  3  and  5

                    x2 + 3x + 5x + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x+3)

             Add up the last 2 terms, pulling out common factors :

                   5 • (x+3)

Step-5 : Add up the four terms of step 4 :

                   (x+5)  •  (x+3)

            Which is the desired factorization

Equation at the end of step  3  :

 (x + 5) • (x + 3)   (x + 4) • (x - 4)

 ————————————————— • —————————————————

       x - 4            2 • (x + 3)  

Step  4  :

Canceling Out :

4.1    Cancel out  (x+3)  which appears on both sides of the fraction line.

Canceling Out :

4.2    Cancel out  (x-4)  which appears on both sides of the fraction line.

Final result :

 (x + 5) • (x + 4)

Answers

Answer:

answer is B...2 1/2

Step-by-step explanation:

4(t+1)=6t-1

4t+4=6t -1

4t-6t+4=6t-6t-1

-2t+4=-1

-2t+4-4=-1-4

-2t=-5

Divide by -2 for -2t and -5

-2t/-2=-5/-2

t=5/2= 2 1/2

Answer is b) 2 1/2

PLEASE DON'T USE A TRANSLATOR.Amanda brought flowers and decided to visit her sister Jessica at the hospital when she had some free time. Jessica use to be healthy and was in good shape. She use to work in the garden outside of her household. Amanda was planning to invite her sister to go to the movies with her on Saturday. After all, Jessica was like a friend to Amanda and is her best friend. Until, Jessica had recently been diagnosed with a severe heart condition, causing her to have a heart attack. She was very sick and in pain. The only way for Jessicas health to improve, is to undergo an expensive surgery that Amanda or their family cant afford. Since Amanda works as a banker, she decided to steal money in the bank vaults to give and pay for Jessicas surgery. The nurses informed Jessica about her upcoming surgery, unaware of how Amanda obtained the money. A few weeks later, Amanda was mentally preparing herself to tell her sister about how she stole the money from her job. She could already imagine and see the disappointment in Jessicas eyes. A worried expression appeared on Amandas face. Her slender fingers were about to touch and move to the doorknob. Until, she was able to hear an ongoing conversation echoing outside her sisters hospital door. Slowly, Amanda placed her ear against the wooden door. After a few minutes later, the door opened and Amanda quickly stepped away from the door and to the side. A raised eyebrow was shown on the females face, as she blinked in suspicion. Her eyelashes fluttering up and down in the process. Slowly, Amanda entered her sisters hospital room and observed the room, as well as her ill sister. Amanda noticed Jessicas pale skin. Earlier, Amanda had spoken to a different nurse of hers. From what the woman had mentioned, Amanda noticed her sisters frail figure. Jessicas previous nurse said that she couldnt eat because of her stomach hurting her around her waist, her cheeks were flushed, her muscles were sore and bothering her, along with the right side of her body bothering her including her right wrist, ankle, elbow, hip, thigh, arm, leg, and knee. Possibly due to the uncomfortable hospital beds. Amanda told her that her sister needed to rest and to exercise, so her body wouldnt be weak.
