Answer:

hdbj

Step-by-step explanation:

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

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.

Answer: 3.25

Step-by-step explanation:

Answer:Should be 65%

Step-by-step explanation:

Answer:

65%

Step-by-step explanation:

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

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

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]

Therefore correct option is D.

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
