The value of g(-4) for the given function g(x)=x+4 is 0.

Piecewise functions are functions that have multiple pieces, or sections. They are defined piece by piece, with various functions defining each interval. Piecewise functions can be split into as many pieces as necessary. Each piece behaves differently based on the input function for that interval. Pieces may be single points, lines, or curves.

For −5 ≤ x ≤ −1

Lets take all range of values of x

g(-5) = x + 4 = -5 + 4 = -1

g(-4) = x + 4 = -4 + 4 = 0

g(-3) = x + 4 = -3 + 4 = 1

g(-2) = x + 4 = -2 + 4 = 2

g(-1) = x + 4 = -1 + 4 = 3

For −1 < x ≤ 5

Lets take all range of values of x

g(0) = 2 - x = 2 - 0 = 2

g(1) = 2 - x= 2 - 1 = 1

g(2) = 2 - x= 2 - 2 = 0

g(3) = 2 - x= 2 - 3 = -1

g(4) = 2 - x= 2 - 4 = -2

g(5) = 2 - x= 2 - 5 = -3

Therefore, the value of g(-4) for the given function g(x)=x+4 is 0.

Answer:

Since there is one value of  y  for every value of  x  in  ( 1,−2) ,( 2,1),(3,6), (4,13 ) ,(5 ,22 ) , this relation is a function.

The relation is a function.

A relation is a function if it has only one y-value for each x-value. The relation (1,−2), (2,1), (3,6), (4,13), (5,22) is a function.

A relation is a function if it has only one y-value for each x-value.

The given relation is one comma minus two

two comma one

Answer: Kavitha is 18 and Lizzy is 27

Step-by-step explanation: 8 years ago, Kavitha was 10 and Lizzy was 19.

10 × 2 = 20

20 - 1 = 19

Kavitha is 9 years younger than Lizzy because 27 - 9 = 18

9514 1404 393

Answer:

  Kavitha is 19 and Lizzy is 28

Step-by-step explanation:

Let k and l represent the current ages of Kavitha and Lizzy.

  k = l -9 . . . . . Kavitha is 9 years younger

  l -8 = 2(k -8 -1) . . . . 8 years ago, Lizzy was 2 times as old as Kavitha was 9 years ago

  l -8 = 2(l -9 -9) . . . . substitute for k

  l -8 = 2l -36 . . . . . . eliminate parentheses

  28 = l . . . . . . . . . . . add 36 - l

  k = 28 -9 = 19

Kavitha is 19; Lizzy is 28.

Answer:

a

    [tex]A =  \$66 \foot [/tex]

b

   tex]C(10)' = \$60  /  feet[/tex]

c

   [tex]C(10)' = \$79.696 \ feet  [/tex]

Step-by-step explanation:

From the question we are told that

  The price per square foot of a floor tile is  [tex]p = \$ 3[/tex]

   The cost of shipping is  [tex]s =  \$ 20[/tex]

  The current length of the square bathroom is x =  10 ft

   The new length is  [tex]x_ 1 =  12 \  ft[/tex]

Generally the equation representing the cost of the square tile is mathematically represented as  

       [tex]C(x) =  3x^2 + 20[/tex]

Generally the average rate of change of cost is mathematically represented as

   [tex]A =  \frac{ cost \ for\  a \  12 feet \  bathroom - cost \ for\  a \  10 feet \  bathroom  }{12 feet  - 10 feet}[/tex]

Generally the cost for flooring a 12 feet square bathroom is mathematically represented as

             [tex]C(12) =  3(12)^2 + 20[/tex]

=>           [tex]C(12) = \$ 452 [/tex]

Generally the cost for flooring a 10 feet square bathroom is mathematically represented as

            [tex]C(10) =  3(10)^2 + 20[/tex]

=>          [tex]C(10) =  \$320[/tex]

So

            [tex]A =  \frac{ 452- 320 }{12 feet  - 10 feet}[/tex]

=>          [tex]A =  \$66 \foot [/tex]

Generally the instantaneous rate of change of cost is obtained by the differentiating the cost function as follows

         [tex]C(x) =  3x^2 + 20[/tex]

         [tex]C(x)' = \frac{dC(x)}{dx}  =  6x[/tex]

So the instantaneous rate of change of cost at length 10 feet is mathematically represented as

         [tex]C(10)' = 6(10)[/tex]

=>       [tex]C(10)' = \$60  /  feet[/tex]

Generally given that the new cost function is  

         [tex]C(x) =  20(1 + sinx) + 3x^2[/tex]

Now the instantaneous rate of change of cost will now be

       [tex]C(x)' =  20cos(x) + 6x[/tex]

So the instantaneous rate of change of cost at length 10 feet is mathematically represented as

         [tex]C(10)' =  20cos(10) + 6* 10 [/tex]

=>        [tex]C(10)' = \$79.696 \ feet  [/tex]

Answer:

The width is 3 ft

The length is  12 ft

Step-by-step explanation:

Let w = width

l = 4w

A = l*w

Replace length with 4w

A = 4w*w

36 = 4 w^2

Divide each side by 4

36/4 = 4w^2/4

9 = w^2

Take the square root of each side

sqrt(9) = sqrt(w)

3 =w

The width is 3 ft

The length is 4*3 = 12 ft

An easy way of solving problems like these is to count the number of zeros in the equation, temporarily remove them, solve the new problem, and then add all the zeros that you removed before. In this case:

100 x 20 = ?

1 x 2 = ?  | 000

2 | 000

Answer:

A. 0.22

B. 0.18

C. 0.25

D. 0.244

Step-by-step explanation:

S = {51 to 100} = 50

The sample space S contains values from 51 to 100 which is a total of 50 different values.

A.

Probability of A (lies between the values of 90 to 100 = 11).

11/50 = 0.22

B.

For a student to fail the course, his course has to be less than 60 = from 51 to 59. A total of 9 values.

9/50 = 0.18

C.

For student to get c, (70 to 79) a total of 10 values: 10/50 = 0.20

P(student did not get C) = 1-0.20 = 0.80

To get B, ( 80 to 89)

10/50 = 0.20

Probability that a student who is known not to have a c grade has a b grade = 0.20/0.80 = 0.25

D.

Probability of passing lies between 60 to 100 = 41 scores

41/50 = 0.82

Probability of student who passed having a B = 0.20/0.82 = 0.244

All answers agree that the slope = - 3

y intercept

So far what you know is that the line is

y = -3x + b

The point shows that

5 = -3*2 + b                    Combine right

5 = -6 + b                        Add 6 to both sides

5 + 6 = -6+6 + b             Combine

11 = b

So the y intercept = 11
