For all values of x, f(x) = x^2 + 1 and g(x) = x-5
(a) Show that fg(x) = x^2 - 10x + 26
(b) Solve fg(x) = gf(x)

Answers

Answer:

a)  f g(x) =  x³ - 5 x² + x -5

b) g(f(x) =  x³ - 5 x² + x -5

Step-by-step explanation:

Step(i):-

Given that f(x) = x² + 1 and g(x) = x-5

a)

      f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26

Step(ii):-

a) f g(x)  = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5

b)   g(f(x)  = g(x) f(x) = (x-5) (x²+1) =  x³ - 5 x² + x -5

1. Two linear functions are shown below. Which function has the greater
rate of change?

Answers

Answer:

Function A

Step-by-step explanation:

Function A rate of change:

Using two given pairs of values, (4, 32) and (8, 44):

Rate of change = ∆y/∆x

= (44 - 32)/(8 - 4)

= 10/4

Rate of change = ⁵/2

Function B rate of change:

Using two points on the line, (2, 4.5) and (4, 6.5):

Rate of change = ∆y/∆x

= (6.5 - 4.5)/(4 - 2)

= 2/2

Rate of change = 1

Function A has the greater rate of change

Function A has the greater rate of change.

Here, we have,

Function A rate of change:

Using two given pairs of values, (4, 32) and (8, 44):

Rate of change = ∆y/∆x

= (44 - 32)/(8 - 4)

= 10/4

=5/2

Rate of change = 5/2

Function B rate of change:

Using two points on the line, (2, 4.5) and (4, 6.5):

Rate of change = ∆y/∆x

= (6.5 - 4.5)/(4 - 2)

= 2/2

Rate of change = 1

Function A has the greater rate of change.

Consider the sequence 5, 12, 19, 26, ...

Enter numbers in the boxes to represent the fourth term as an ordered pair.

Answers

Answer:

5, 12, 19, 26, 33

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding 7 to the previous term in the sequence gives the next term. In other words, an=a1 + d(n − 1) .

Arithmetic Sequence:  d=7

This is the formula of an arithmetic sequence.an=a1 + d(n-1)

Substitute in the values of

a1=5 and d=7. an=5 + (7) (n − 1)

Simplifly each term : an=5 + 7n − 7

Subtract  7  from 5.

an=7n − 2

A √13

B √52

C √60

Answer:

D. [tex]\sqrt{65}[/tex]

Step-by-step explanation:

The computation of the  length of a diagonal (AC or BD) of the rectangle is shown below:

As we know that

The Diagonal length of AC is

[tex]= (x_2 - x_1)^2 + (y_2 - y_1)^2\\\\= (9 -2)^2 + (8 - 4)^2\\\\= (7)^2 + (4)^2[/tex]

[tex]= \sqrt{49 + 16}\\\\= \sqrt{65}[/tex]

The scatter plot shows the number of CDs in millions that were sold from 2011 to 2016. Use the points (2, 2485.6) and (6, 1172.5) to write an equation of the line of fit in slope-intercept form. Let x be the years since 2010 and let y be the number of CDs in millions sold.

Answers

Answer:

slope -intercept form

y = -328.275 x + 3142.15

Step-by-step explanation:

Step(i):-

Given that the points are (2, 2485.6) and (6,1172.5)

The slope of the line

               [tex]m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]

              [tex]m = \frac{1172.5-2485.6 }{6-2 }[/tex]

            [tex]m = - 328.275[/tex]

Step(ii):-

Equation of the straight line passing through the Point (2,2485.6)

[tex]y - y_{1} = m(x-x_{1} )[/tex]

y - 2485.6 = (-328.275)(x-2)

y - 2485.6 = -328.275x+656.55

  y =  -328.275x+656.55 + 2485.6

y = -328.275 x + 3142.15

Final answer:-

slope -intercept form

y = -328.275 x + 3142.15

a . 2 kilograms
b . 4 kilograms
c . 6 kilograms
d . 8 kilograms ​

Answers

None of those it will be 3

There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Fruit weight = 53 kilograms

And, Another weight = 47 kilograms

Now,

Let number of kilograms weights to remove and add = x

So, We can formulate;

⇒ 53 - x = 47 + x

Solve for x as;

⇒ 53 - 47 = x + x

⇒ 6 = 2x

⇒ 2x = 6

⇒ x = 3

Thus, There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.
