Write 2339 in scientific notation

Answer:

They are not equivalent

Step-by-step explanation:

We want to determine if 1/2(4 - 2x); 2 - 2x are equivalent.

Let us take the first expression and simplify to see if we can get the second expression.

[tex] \frac{1}{2}(4 - 2x)[/tex]

Let us expand using the distributive property to get:

[tex] \frac{1}{2} (4 - 2x) = \frac{1}{2} \times 4 - \frac{1}{2} \times 2x[/tex]

This simplifies to:

[tex]\frac{1}{2} (4 - 2x) = 2 - x[/tex]

Therefore 1/2(4 - 2x); and 2 - 2x are not equivalent

Carlos made the mistake that he did not combine like terms (3 x and 2 x) properly and did not use addition property of equality.

Step-by-step explanation:

Carlos did the work as 3 x + 2 x - 6 = 24

We need to find his mistake that he made in above given.

Here, he did not add the like terms (3 x and 2 x)

             3 x + 2 x = 5 x

Therefore, his work should be

             5 x  - 6 = 24

Also, he did not use addition property of equality. It means the equation remains same even though the same number gets added on both sides. It would be

                          5 x  - 6 = 24

                                 + 6 = + 6

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

                           5 x = 30

Dividing 30 by 5, we get answer as '6'. Hence,

                            [tex]x=\frac{30}{5}[/tex] = 6

So, stated the above two are the mistakes found in carlos work.

Answer:

see explanation

Step-by-step explanation:

Given

2x³ - x² + 18x - 9 = 0 ( factor the first/second and third/fourth terms )

x²(2x - 1) + 9(2x - 1) = 0 ← factor out (2x - 1) from each term

(2x - 1)(x² + 9) = 0

Equate each factor to zero and solve for x

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

x² + 9 = 0 ⇒ x² = - 9 ⇒ x = ± 3i

The equation has 1 real solution and 2 complex solutions

x = [tex]\frac{1}{2}[/tex] ← real solution

x = ± 3i ← complex solutions

Percent increase without baggage = 46%

Percent increase with baggage = 66%

Step-by-step explanation:

Cost of ticket two weeks ago= Old value = $250

Increased cost = New value = $365

Change = New value - Old value

Change = 365 - 250 = $115

Percent increase = [tex]\frac{Change}{Old\ value}*100[/tex]

Percent increase = [tex]\frac{115}{250}*100[/tex]

Percent increase = [tex]\frac{11500}{250}=46\%[/tex]

There is 46% increase in the price.

Change after additional baggage = 115+50 = $165

Percent increase = [tex]\frac{165}{250}*100[/tex]

Percent increase = [tex]\frac{16500}{250}=66\%[/tex]

Percent increase without baggage = 46%

Percent increase with baggage = 66%

The percent increase in the cost of airline tickets from Orlando to Denver is 46%. If an additional $50 baggage fee is charged, the percent increase is 66%.

To calculate the percent increase, we can use the formula: Percent Increase = ((New Value - Old Value) / Old Value) x 100. In this case, the old value is $250 and the new value is $365. Therefore, the percent increase is ((365 - 250) / 250) x 100 = 46%.

If the airline charges an additional $50 baggage fee, the new ticket price would be $365 + $50 = $415. To calculate the percent increase from the original price, we can use the same formula. The old value is still $250 and the new value is $415. Therefore, the percent increase with the added baggage fee is ((415 - 250) / 250) x 100 = 66%.

Answer:

4.64

Step-by-step explanation:

To simplify mixed numbers you can write them either as a fraction or as a decimal number.

Fraction:

first we need to express both parts of mixed number through the same denominator - 1 has 25/25, so that means 4 has 100/25.

Now we can write that as 100/25 and 16/25, which is (100+16)/25 = 116/25

Decimal number:

This time, we convert this fraction part of a number to decimal. Simply dividing, we get that 16/25 equals 0.64. So 4 and 0.64 is 4.64.

Answer:

The height of the building is [tex]1\frac{1}{4}\ feet.[/tex]

Step-by-step explanation:

Given:

Scale drawing is 1/4 inch: 1 foot.

The height of the building in drawing is 5 inches.

Now, to find the actual height of the building.

Let the actual height be [tex]x.[/tex]

The height of the building in drawing = [tex]5\ inches.[/tex]

The ratio of the scale drawing is [tex]\frac{1}{4}\ inch:1\ foot.[/tex]

So, [tex]\frac{1}{4}\ inch[/tex] is equivalent is 1 foot.

Thus, 5 inches is equivalent to [tex]x.[/tex]

Now, to get the actual height of the building by using cross multiplication method:

[tex]\frac{\frac{1}{4}}{1} =\frac{5}{x}[/tex]

[tex]\frac{4}{1} =\frac{5}{x}[/tex]

By cross multiplying we get:

[tex]4x=5[/tex]

Dividing both sides by 4 we get:

[tex]x=\frac{5}{4}[/tex]

[tex]x=1\frac{1}{4}[/tex]

Therefore, the height of the building is [tex]1\frac{1}{4}\ feet.[/tex]

The correct answer is E. Both functions are linear, only crossing the x-axis once and the y-axis once.

We can see from the graph that both Function A and Function B are straight lines. This means they are linear functions.

Linear functions also have only one x-intercept and one y-intercept. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

The y-intercept for both Function A and Function B is at (0,0). The x-intercept for Function A is at (-2,0) and the x-intercept for Function B is at (1,0).

Therefore, both statements in choice E are true.

The other statements in the question are not true.

Choice A, Both functions have negative rates of change, is not true. Function A has a negative rate of change, but Function B has a positive rate of change.

Choice B, Both functions have the same rate of change, is not true, as discussed above.

Choice C, When graphed, Function A and Function B are parallel, is not true. Parallel lines would never intersect, but the two functions intersect at the origin.

Choice D, Function A has a greater rate of change than Function B, is not true. The slope of Function B is steeper than the slope of Function A, so Function B has a greater rate of change.

Step-by-step explanation:

To know who earned the most commission, one must multiply the number of items sold by each salesperson by their respective commission rates. The one with the highest total is the salesperson who earned the most commission.

To determine who earned the most commission, you first need to have concrete data. This should include the number of items each salesperson sold and the commission rate or amount associated with each item.

Multiply the number of items each person sold by the respective commission to get the total commission earned by each salesperson.

The salesperson with the highest total commission is the one who earned the most. For instance, if salesperson A sold 50 items with a commission of $2 per item, their total commission would be 50*2 = $100.

If salesperson B sold 30 items at $5 per item, their total would be 150.

Hence, in this situation salesperson B earned more commission even though they sold fewer items.

[tex](-2)^{3}=-8[/tex]

Step-by-step explanation:

Simplify

-2^3

[tex](-2)^{3}[/tex]

It is read as negative 2 raised to the power three,

also it is the cube of negative 2

we know that [tex]a^{3}[/tex]given as

[tex]a^{3}=a\times a\times a[/tex]

so for negative a i.e -a

Answer:

-13/2

Step-by-step explanation:

slope is calculated as (y2-y1)/(x2-x1)

(x1, x2) is (1,6) and (y1,y2) is (3,-7)

doing (y2-y1)/(x2-x1) gives us ((-7)-6)/(3-1)

= -13/2

The slope between the points (1,6) and (3,-7) is calculated as -6.5 using the slope formula.

The slope between two points (1,6) and (3,-7) can be calculated using the slope formula: m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of the points.

In this case, substituting the values in, we get:

m = (-7 - 6) / (3 - 1) = -13 / 2 = -6.5.

Thus, the slope between the points (1,6) and (3,-7) is -6.5.

[tex]m \angle LKN + m \angle \boxed{KLM} = \boxed{180}[/tex] because they are [tex]\text{supplementary angles}[/tex]

This is true of any parallelogram. The adjacent angles of any parallelogram are supplementary, meaning they add to 180 degrees. You can use the same side interior angle theorem here as well.

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

Because KA cuts angle K in half, and LA does the same to angle L, this means that we're dividing everything by 2 in that equation at the top of the page. So we have,

[tex]\frac{m \angle LKN + m \angle KLM}{2} = \frac{180}{2}[/tex]

and that turns into

[tex]m \angle LKA + m\angle KLA = 90[/tex]

which tells us that angle KAL must be 90 so that the three angles of triangle KAL add to 180 degrees. For any right triangle, the acute angles are complementary, meaning they add to 90 degrees.
