Choose the equivalent factored form

Answer:

$18

Step-by-step explanation:

The initial price is $25

When the first 10% is off, the new amount is (100 - 10)% x 25

= 0.9 x 25

= 22.5

With an additional 20%

the new amount is (100 - 20)% x 22.5

= 0.8 x 22.5

= $18

The final price of the shirt is $18.00.

To find the final price of the shirt, we need to apply the discounts consecutively to the original price.

 First, we calculate the discount from two weeks ago, which was 10% off the original price of $25.00. A 10% discount is the same as multiplying the price by 0.9 (since 100% - 10% = 90%, or 0.9 in decimal form).

 So, after the first discount, the price of the shirt is:

[tex]\[ \text{Price after first discount} = 25 \times 0.9 = 22.50 \][/tex]

 Next, we apply the additional 20% discount to the original price, not to the already discounted price.

This means we calculate 20% of $25.00 and subtract that from the original price. A 20% discount is the same as multiplying the price by 0.8 (since 100% - 20% = 80%, or 0.8 in decimal form).

 So, after the second discount, the price of the shirt is:

[tex]\[ \text{Price after second discount} = 25 \times 0.8 = 20.00 \][/tex]

However, since the second discount is additional, we need to apply it to the already discounted price of $22.50.

Therefore, we calculate 20% of $22.50 and subtract that from $22.50.

[tex]\[ \text{Additional discount amount} = 22.50 \times 0.2 = 4.50 \][/tex]

[tex]\[ \text{Price after additional discount} = 22.50 - 4.50 = 18.00 \][/tex]

 Thus, the final price of the shirt after both discounts is $18.00.

Final answer:

Vertex-edge graphs can model real-world problems, not all graphs can be solved, Euler paths and Hamilton paths are different, and in a Hamilton circuit, all vertices must be used exactly once.

Explanation:

Vertex-edge graphs, also known as graphs or networks, are mathematical structures that consist of vertices (also called nodes) connected by edges. They are widely used to model real-world problems across various fields such as computer science, transportation planning, and social networks, among others (1). While some vertex-edge graphs can be solved, it is not true that all graphs can be solved. Solvability depends on the specific problem being represented by the graph and the algorithms or methods used to solve it (2). Euler paths and Hamilton paths are not the same. An Euler path is a path in a graph that visits every edge exactly once, while a Hamilton path visits every vertex exactly once (3). In a Hamilton circuit, all vertices must be used exactly once, but not in a Hamilton path. There can be more than one Hamilton path in a graph, depending on its structure (4).

Answer:

[tex]3x^{3}-2x^{2} +6x[/tex]

Step-by-step explanation:

The cubic trinomial is in this form :

[tex]Ax^{3}+Bx^{2} +Cx[/tex]

So, instead A, B, and C we can use any number.

We use :

A=3

B=2

C=6

[tex]3x^{3}-2x^{2} +6x[/tex]

A cubic polynomial has a degree of 3.

Since 3 is the highest degree, the polynomial could contain terms with degree 2, 1, or 0 (quadratic, linear, or constant).

A trinomial can have only 3 terms.

Including terms with degrees of 3, 2, 1, and 0 would mean the polynomial has 4 terms.

The cubic trinomial could consist of a cubic, quadratic, and linear term, with no constant term.

Step-by-step explanation:

the correct answer is: ( x ) equals negative 1 plus or minus 2 I square root of 2

To solve the equation [tex]\( x^2 + 2x + 9 = 0 \)[/tex], you can use the quadratic formula:

[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]

In this case, [tex]\( a = 1 \), \( b = 2 \), and \( c = 9 \)[/tex]. Substituting these values into the formula:

[tex]\[ x = \frac{-2 \pm \sqrt{(2)^2 - 4(1)(9)}}{2(1)} \]\[ x = \frac{-2 \pm \sqrt{4 - 36}}{2} \]\[ x = \frac{-2 \pm \sqrt{-32}}{2} \]\[ x = \frac{-2 \pm 4i\sqrt{2}}{2} \]\[ x = -1 \pm 2i\sqrt{2} \][/tex]

So, the correct answer is: ( x ) equals negative 1 plus or minus 2 I square root of 2.

Answer:

-3 and 6

Step-by-step explanation:

-3 + 6 = 3

-3 * 6 = -18

Final answer:

The two numbers that add up to 3 and multiply to -18 are 6 and -3. By setting up equations based on these conditions and solving them, we determine these two numbers.

Explanation:

The question asks about two numbers that when added together equal 3, and when multiplied together equal -18. To find these numbers, we need to set up a system of equations based on the given conditions:

Let the two numbers be x and y.

The sum of x and y is 3: x + y = 3.

The product of x and y is -18: xy = -18. Let's use factorization and proceed as follows:

Assume y = 3 - x.

Substitute y into the second equation: x(3 - x) = -18.

This simplifies to x2 - 3x - 18 = 0.

Factor the quadratic: (x - 6)(x + 3) = 0.

So, x = 6 or x = -3.

Using x + y = 3, if x = 6, then y = -3. If x = -3, then y = 6.

The two numbers that satisfy the given conditions are 6 and -3.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

-5x+3y=51 ..........(1)

y=10x-8 .............(2)

Put the value of y from equation (2) in equation (1) we get

-5x+ 3(10x - 8)= 51

-5x + 30x - 24 = 51

25x = 51+ 24

25x = 75

x= 3

and, y= 10(3)- 8= 30 -8 = 22

Hence, the value of x is 3 and y is 22.

Answer:

The sales price of the camcorder is  $742.41 .

Step-by-step explanation:

The Cost Price of camcorder  = $678

The sales Tax = 9.5%

Now, 9.5% of the cost price $678 =  [tex]\frac{9.5}{100} \times (678) = 64.41[/tex]

5x + y - 4 = 0

Step-by-step explanation:

When we are given two points and are asked to find the equation of the line we use the two - point form.

Two - point form: [tex]$ \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1} $[/tex].

We can conclude that Δ ABC ≅ Δ DEF by AAS postulate.

Step-by-step explanation:

Δ ABC and Δ DEF are congruents because:

1. Their non-included sides BC and EF are equal (7 units = 7 units)

2. Their angles ∠A and ∠D are equal (39° = 39°)

3. Their angles ∠C and ∠F are equal  (64° = 64°)

Now, we can conclude that Δ ABC ≅ Δ DEF by AAS postulate.

Answer:

Step-by-step explanation:

From the given diagram we notice that

1. Line AB is equal to Line DE.

2. Line AC is equal to line DF.

3. Angle A is equal to angle D

Then, it shows that 2 sides of the triangle are similar and 1 of it's angle is also similar. Then, it is SAS

Where, S- represent sides and A- represents angle

NOTE : we have SSS, ASA, AAS and SAS, we don't have SSA

To write the similar triangle equation

∆ABC ≈ ∆DEF

Since AB is equal to DE, the we replace It with DE and also Angle A is equal to angle D. Also AC is equal to DF, then we replace C with F.

So the answer is C

∆ABC ≈ ∆DEF SAS

Answer:

I'm pretty sure that you would try to find the least common multiple.

Step-by-step explanation:

Final answer:

When adding fractions, you need to find a common denominator using the least common multiple (LCM) of the denominators. In this case, the LCM of 5 and 6 is 30, so you multiply each fraction by a factor to make the denominators the same. Then, you can add the numerators together.

Explanation:

When adding fractions, you need to use the least common multiple (LCM) of the denominators to find a common denominator. In this example, the denominators are 5 and 6. The LCM of 5 and 6 is 30, so you need to find equivalent fractions with a denominator of 30.

To do this, multiply the numerator and denominator of each fraction by a factor that will result in a denominator of 30. For the first fraction, multiply both the numerator and denominator by 6 to get 24/30. For the second fraction, multiply both the numerator and denominator by 5 to get 25/30.

Finally, you can add the numerators together (24 + 25 = 49) and keep the common denominator of 30, giving you the final fraction of 49/30.

FC can then be computed using pythagoras theorem such that

FC^2 = FC'^2 + CC'^2

FC^2 = (14.6/2)^2 + (9.8/2)^2

FC^2 =53.29 + 24.01

FC^2 = 77.3

FC = sqrt(77.3) = 8.8

To determine the height of the attic, we estimate EF, Pythagoras theorem can be used for triangle EFC

such that EC^2 = EF^2 + FC^2

therefore EF^2 = EC^2 - FC^2

EF^2 = 12.9^2 - 8.8^2

EF^2 = 166.41 - 77.44

EF^2 = 88.97

EF = sqrt(88.97)

EF = 9.4

The height of the attic is therefore 9.4m

BC = 28

Step-by-step explanation:

Since the triangle is equilateral then all 3 sides are congruent.

Equate AB and AC and solve for x, that is

12x + 4 = 8x + 12 ( subtract 8x from both sides )

4x + 4 = 12 ( subtract 4 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2, thus

AC = 8x + 12 = (8 × 2) + 12 = 16 + 12 = 28

Since the 3 sides are congruent then BC = 28

Answer:

The company's profit be in the year 2008 is $8.3 million.

Step-by-step explanation:

Given:

In the year 2006, a company made $7 million in profit, their profit increased by 9%.

So, we need to calculate the company's profit be in the year 2008.

Now, by putting the formula to find the profit(P) after the two year:

Difference between the year = 2008 - 2006 = 2 year.

So, number of years(n) = 2 year

Rate of profit increasing(r) = 9%

Amount company made in 2006 (A) = $7 million.

[tex]P=A(1+\frac{r}{100})^{n}[/tex]

[tex]P=7(1+\frac{9}{100})^{2}[/tex]

[tex]P=7(1+0.09)^{2}[/tex]

[tex]P=7(1.09)^{2}[/tex]

[tex]P=7\times 1.188[/tex]

[tex]P=8.316[/tex]

Profit in the year 2008 would be 8.316 million, and nearest to the tenth of a million dollars is $8.3 as 3 is in the tenth place of the decimal and 1 in the hundredth so rounding will change $8.316 to $8.3.

Therefore, the company's profit be in the year 2008 is $8.3 million.

Final answer:

To find the company's profit in 2008 after a 9% increase each year from 2006, we calculate compound growth over two years. The profit in 2008 would be $8,316,700, which rounds to $8.3 million.

Explanation:

To calculate the company's profit in the year 2008 after it increased by 9% each year following 2006, we can use the formula for compound interest which is similar to calculating compounded profit growth. The formula is:

[tex]P = P_0 \times (1 + r)^t[/tex]

Where:

P is the future profit

P₀ is the initial profit ($7 million)

r is the annual growth rate (9% or 0.09)

t is the number of years since 2006 (2008 - 2006 = 2 years)

Let's calculate the profit for 2008:

P = $7,000,000 × (1 + 0.09)²

First, calculate the growth factor for one year:

1 + 0.09 = 1.09

Now, apply the growth factor for two years:

1.09² = 1.1881

Multiply the initial profit by the growth factor:

P = $7,000,000 × 1.1881 = $8,316,700

To the nearest tenth of a million dollars, the company's profit in 2008 would be $8.3 million.

Answer:

The measure angle ADB = 180 - (α/2+ β/2) 

Step-by-step explanation:

measure angle A is α degrees, this means that, the angle bisector divides the angle into two equal angles each of measure α/2 degrees

measure angle B is β degrees, this means that the angle bisector divides the angle into two equal angles each of measure β/2 degrees

In triangle ADB, we know that the sum of all measure of a triangle is 180 degrees and we have measure angle MAB = α/2 degrees and measure angle MBA = β/2 degrees

Therefore,

measure angle ADB = 180 - (α/2+ β/2)
