Wich number is written in the scientific notation

Estimates are used to make prediction about an actual value

The chart is given as:

Fruit     Cost                  Estimated

Apple   $1.75/pound     8.75

Orange $2.35/pound   9.40

Banana $1.50/pound    4.50

The number of pounds of each fruit Annie bought are:

[tex]Apples= 5[/tex]

[tex]Orange = 4[/tex]

[tex]Banana = 3[/tex]

(a) The estimated amount

To do this, we make use of the estimated column.

So, we have:

[tex]Estimated = \sum Cost \times Pounds[/tex]

[tex]Estimated =1.75*5+8.75*4+1.50*3[/tex]

Approximate the prices

[tex]Estimated =2*5+9*4+2*3[/tex]

[tex]Estimated =52[/tex]

Hence, Annie estimated spending $52

(b) The actual amount spent

To do this, we make use of the cost column.

So, we have:

[tex]Actual = \sum Cost \times Pounds[/tex]

[tex]Actual =1.75*5+8.75*4+1.50*3[/tex]

[tex]Actual =48.25[/tex]

Hence, Annie actually spent $48.25

(c) The decision

By comparison, the estimated spending is greater than the actual amount spent.

Hence, your estimation is an overestimation

We define transformations as operators that act on functions by modifying them in some given way. One type of transformation is a translation, which will move the whole graph of the function in some give direction.

For a general function f(x), we will find that the equation for the result of shifting the graph up by 4 units and left by 2 units is:

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

----------------------------------

Let's see how to solve this.

We need to start by defining the two most common translations (also known as shifts).

Horizontal translation:

For a given function f(x), an horizontal translation of N units is written as:

g(x) = f(x + N)

where if N is positive, the translation is to the left.

If N is negative, the translation is to the right.

Vertical translation:

For a given function f(x), a vertical translation of N units is written as:

g(x) = f(x) +  N

Where if N is positive, the translation is upwards.

If N is negative, the translation is downwards.

Here for an unknown function f(x), we want to write the equation that gives a shift up of 4 units and left by 2 units.

The shift up of 4 units is written as:

g(x) = f(x) + 4

The shift of 2 units to the left is written as:

g(x) = f(x + 2)

These two together give:

g(x) =  f(x + 2) + 4.

This is the equation we wanted to get.

log ( x^2/(yz^2))

Step-by-step explanation:

2 log x - log y - 2 log z

We know a log b = log b^a

Rewriting

2 log x = log x^2  and 2 log z = log z^2

log x^2 - log y -  log z^2

Rewriting

log x^2 - (log y +  log z^2)

We know that log a + log b = log (a*b)

log x^2 - (log (y z^2))

And we know log a - log b = log (a/b)

log ( x^2/(yz^2))

Step-by-step explanation:

Answer:

10 headbands = $12.50

Step-by-step explanation:

1) The function equation that represents the relationship between the number of headbands sold (x) and the commission earned (S) is: S = 1.25 * x. For each headband sold, you earn a commission of $1.25.

2) The point (5, 6.5) is not a solution for the function. When you sell 5 headbands, the commission earned should be $6.25, not $6.5.

3) A solution that does not appear in the table is (10, 12.50). Selling 10 headbands would result in a commission of $12.50.

1.

To complete the table, we can use the given information that for each headband sold, you earn a commission of $1.25.

Function Rule (Commission S): The function equation that represents the relationship between the number of headbands sold (x) and the commission earned (S) is:

S = 1.25 * x

Now, we can use this function to fill in the table:

Number of Headbands Sold (x) | Commission (S)

0 | 0 * 1.25 = $0 (No commission earned for 0 headbands sold)

1 | 1 * 1.25 = $1.25

2 | 2 * 1.25 = $2.50

3 | 3 * 1.25 = $3.75

7 | 7 * 1.25 = $8.75

15 | 15 * 1.25 = $18.75

32.50 | 32.50 * 1.25 = $40.625 (The value in the table seems to be a typo, it should be 32.50 * 1.25 = $40.625)

2.

To check if (5, 6.5) is a solution for the function, we need to see if the commission earned (S) matches with the given number of headbands sold (x) for that point.

Given (x, S) = (5, 6.5)

Using the function rule: S = 1.25 * x

S = 1.25 * 5 = 6.25

The commission earned (S) is $6.25, not $6.5. Therefore, (5, 6.5) is not a solution for the function as the value of S does not match.

3.

To identify a solution that does not appear in the table, we can select any number of headbands sold (x) and calculate the corresponding commission (S) using the function rule.

For example, let's choose x = 10:

Using the function rule: S = 1.25 * 10 = $12.50

So, a solution that does not appear in the table is (10, 12.50), where 10 headbands sold results in a $12.50 commission.

Perimeter = 4(2x - 1)

Step-by-step explanation:

Since the Perimeter of a square is 4L, it would be,

(2x - 1) + (2x - 1) + (2x - 1) + (2x - 1) which could also be shortened to 4(2x - 1)

Answer:

P = 4(2x - 1)

Step-by-step explanation:

Given that the side of each square is 2x - 1:

The formula for finding the perimeter of a square is:

P = 4s

where s represents the side of a square.

Substitute the given value for s into the perimeter formula:

s = 2x - 1

P = 4(2x - 1)

Therefore, the perimeter of the square is 4(2x - 1).
