Answer:

  26, 11, 4, 5, 14

Step-by-step explanation:

To find the value of the function, replace the variable with the number and do the arithmetic.

  f(-2) = 4(-2)² -3(-2) +4 = 16 +6 +4 = 26

For doing repetitive calculations, it is convenient to write the formula into a calculator or spreadsheet and let it work from the list of values. That is what we did in the attached. It shows a table of x and f(x) for the values of x you are interested in.

The function values are ...

_____

Additional comment

For evaluating polynomials, either by hand or machine, it is often convenient to rewrite the polynomial in Horner Form. The total number of math operations tends to be reduced. When doing this by hand, the arithmetic tends to be easier.

  f(x) = (4x -3)x +4

That is, the powers of x accumulate as each layer in parentheses is multiplied by x and the next coefficient added to the result.

Using this form, ...

  f(-1) = (4(-1) -3)(-1) +4

  f(-1) = (-7)(-1) +4 = 11

Answer:

200

Step-by-step explanation:

This problem is about linear equations. We assume Joe drive X miles, and the total cost is $Y, then we can get:

Plan I: Y=51.98+0.17X

Plan II: Y=59.98+0.13X

When both plans cost the same, 51.98+0.17X=59.98+0.13X. We will get X = 200

[tex]\bold{\underline{ Given :- }}[/tex]

[tex]\bold{\underline{ To \: Find :- }}[/tex]

[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]

Let the cost of hamburgers and drinks be x and y

According to the question,

[tex]\sf{ 2x + 4y = 13.00 ...eq( 1 ) }[/tex]

[tex]\sf{ 3x + 7y = 21.00 ...eq(2) }[/tex]

Solving eq( 1 ) we get :-

[tex]\sf{ 2x + 4y = 13 }[/tex]

[tex]\sf{ 2x = 13 - 4y }[/tex]

[tex]\sf{ x = (13 - 4y)/2 ...eq(3)}[/tex]

Subsituting eq(3) in eq( 2 ) :-

[tex]\sf{ 3( 13 - 4y)/2 + 7y = 21 }[/tex]

[tex]\sf{ 39 - 12y/2 + 7y = 21 }[/tex]

[tex]\sf{ 39 - 12y + 14y = 42}[/tex]

[tex]\sf{ 2y = 42 - 39 }[/tex]

[tex]\sf{ 2y = 3 }[/tex]

[tex]\sf{ y = 3/2 }[/tex]

Subsituting value of y in eq(3) :-

[tex]\sf{ x = 13 - 4(3/2)/2}[/tex]

[tex]\sf{ x = 13 - 2(3)/2}[/tex]

[tex]\sf{ x = 13 - 6/2}[/tex]

[tex]\sf{ x = 7/2 }[/tex]

Therefore,

[tex]\sf{ Cost\: of \:8 \:drinks}[/tex]

[tex]\sf{ = 8 * 3/2 }[/tex]

[tex]\sf{ = 4 * 3 }[/tex]

[tex]\sf{ = 12.00 dollars}[/tex]

And

[tex]\sf{ Cost\: of \:9 \:hamburgers }[/tex]

[tex]\sf{ = 9 * 7/2 }[/tex]

[tex]\sf{ = 63/2}[/tex]

[tex]\sf{ = 31.50 dollars}[/tex]

Total cost of the 8 drinks and 9 hamburgers

[tex]\sf{ 12.00 + 31.50}[/tex]

[tex]\sf{\red { = 43.50 \:dollars}}[/tex]

Hence, The total cost paid by you for 8 drinks and 9 hamburgers is $43.50 .

The carrot cakes are the fraction of the cake given by [tex]1 - \frac{6}{7}[/tex] multiplied by [tex]\frac{1}{3}[/tex]

The fraction of the cake that are chocolate cake = [tex]\dfrac{2}{3}[/tex]

The fraction of the remaining cake that cheesecakes = [tex]\dfrac{6}{7}[/tex]

The rest of the cakes = carrot cakes

Required:

The fraction of the cake that  are carrot cakes

Solution:

The fraction of the cakes that are not chocolate cake = [tex]1 - \dfrac{2}{3} = \mathbf{ \dfrac{1}{3}}[/tex]

The fraction of the remaining cakes that are cheesecake = [tex]\dfrac{6}{7} \times \dfrac{1}{3} = \mathbf{ \dfrac{6}{21}}[/tex]

The fraction of the cake that are carrot cake = [tex]\dfrac{1}{3} - \dfrac{6}{7} \times \dfrac{1}{3} = \mathbf{\dfrac{1}{21}}[/tex]

The graph of the parent absolute value function decreases over (–∞, 0) interval.

An absolute value function is a function that contains an algebraic expression within absolute value symbols.

Recall that the absolute value of a number is its distance from 0 on the number line.

The absolute value function is f(x) = |x| is defined as,

[tex]\rm f(x)= x \ if\ x > 0\\\\f(x)= 0 \ if\ x=0\\\\ f(x)=- x \ if\ x < 0\\[/tex]

Observe that the graph is V-shaped.

Hence, the graph of the parent absolute value function decreases over (–∞, 0) interval.

The ending inventory that van be gotten from the table will be $9905 and the cost of goods sold is $5083.

It should be noted that the ending inventory simply means the goods that are still available for sale at the end of an accounting period.

From the complete question, the ending inventory will be:

= $3190 + $2295 + $4420

= $9905

Also, the cost of goods sold will be:

4x² - 27x - 28 is the answer

Step-by-step explanation:

As per question,

(5x² + 23x - 7) - (x² - 4x + 21)

Removing the parentheses,

→ 5x² + 23x - 7 - x² + 4x - 21)

Now reorder and gather the like terms,

→ (5x² - x²) + (23x + 4x) + ( -7-21 )

Collecting the coefficients of like terms,

→ (5-1)x² - (23+4)x + ( -7-21 )

Calculating them now, we get,

→ 4x² - 27x - 28

So, (5x² + 23x - 7) - (x² - 4x + 21) = 4x² - 27x - 28

Answer:

minimum value = 0.001

maximum value = 10

Step-by-step explanation:

To find the minimum and maximum values for the function, substitute the endpoints of the domain into the function:

when x = -3:

[tex]\implies k(-3)=10^{-3}=0.001[/tex]

when x = 1:

[tex]\implies k(1)=10^{1}=10[/tex]

Therefore,

minimum value = 0.001

maximum value = 10

Answer:

43rd term = 50

Step-by-step explanation:

[tex]43rd \: term = 50[/tex]

The required 43rd term will be 50 in the given arithmetic sequence.

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The arithmetic sequence is given in the question as:

260, 255, 250...

This above sequence has:

The first number a₁ = 260

Common difference d = 255 - 260 = -5

The formula to find the general term of an arithmetic sequence is,

Tₙ = a₁ + (n-1)d ...(i)

Substitute the value of d = -5 and a₁ = 260 in the above formula

43rd term = 260 + (43-1)(-5)

43rd term = 260 - 42(5)

43rd term = 260 - 210

43rd term = 50

Therefore, the required 43rd term will be 50.

#SPJ2

Answer:

(0, -7) and (5, 0)

Step-by-step explanation:

y-intercept is when x = 0, therefore (0, -7)

x-intercept is when y = 0, therefore (5, 0)

Answer:

X intercept: (5,0) Y intercept: (0,-7)

Step-by-step explanation:

So you want to look at where you have an x value (input) and it's output (y) is 0 for x intercept, and you want to look at the y value (output) and it's input (x) to be 0 for the y intercept, so on the left we see that 5 = 0, and on the right we see that -7 = 0, and then write them as is, so (5,0) and (0,-7)

Hope that made sense and this helps!

1) The pairs of numbers are:

19 and 91, which do not satisfy the condition

28 and 82, which do not satisfy the condition

37 and 73, which satisfy the condition

45 and 54, which do not satisfy the condition

The number is 37.

Another method:

10x+y+36 = 10y+x, or

9x+36 = 9y, or

x+4= y …(1)

x+y = 10, or

y = 10-x …(2)

Equate (1) and (2)

x+4 = 10-x

2x = 10–4 = 6, or x = 3 so y = 10–3 = 7.

So the number is 37
