f(x) = –2x2 + 8x – 1.

Answer:

B. 1,8, root65

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]1^{2}[/tex] = 1

[tex]8^2[/tex] = 64

[tex](\sqrt{65})^{2}[/tex] = 65

1 + 64 = 65

Final answer:

Only the set of side lengths B (1, 8, √65) forms a right triangle, according to the Pythagorean theorem, as 1^2 + 8^2 equals (√65)^2.

Explanation:

The question asks which set of side lengths form a right triangle. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the two shorter sides (legs) equals the square of the longest side (hypotenuse), which can be expressed as a^2 + b^2 = c^2.

To determine if each set of side lengths forms a right triangle, we can check each option using the Pythagorean theorem:

A: 2, 15, 17 - Check if 22 + 152 = 172.

B: 1, 8,
√65 - Check if 12 + 82 = (
√65)2.

C: 2,
√80, 9 - Check if 22 + (
√80)2 = 92.

After the calculations, we find that:

4 + 225 = 229, which is not equal to 289 (172).

1 + 64 = 65, which is equal to 65 ((
√65)2).

4 + 80 = 84, which is not equal to 81 (92).

Thus, only option B (1, 8,
√65) forms a right triangle.

Step-by-step explanation:

Given the information

=> Total color were left = 1/3 x 4 = 4/3 of the original containers

=> Total color  were planted = (1 - 1/3) x 4 = 2/3 x 4 = 8/3 of the original containers

However,  8/3 = [tex]2\frac{2}{3}[/tex]  > 2[tex]\frac{1}{2}[/tex]  

So she is true, hence, the fractions to determine the total amount of containers of flowers she planted is:  [tex]2\frac{2}{3}[/tex]

Answer:

m = 8

Step-by-step explanation:

4( m-2 ) =24

Divide each side by 4

4/4( m-2 ) =24/4

m-2 = 6

Add 2 to each

m-2+2 = 6+2

m = 8

The ratio 18 ounces to 3 cups is equivalent to 18 ounces to 24 ounces. This is expressed as the fraction 18/24, which simplifies to 3/4 when you divide the numerator and denominator by their greatest common divisor (6).

To express the ratio 18 ounces to 3 cups as a fraction in simplest form, we first need to convert the cups to ounces using the provided conversion factor (1 cup = 8 ounces). Therefore, 3 cups is 3 * 8 = 24 ounces.

So, the original ratio of 18 ounces to 3 cups is equivalent to a ratio of 18 ounces to 24 ounces. This can be written as the fraction 18/24. To simplify this fraction, we find the greatest common divisor (GCD) of 18 and 24, which is 6. We then divide both the numerator (18) and the denominator (24) by this GCD.

Doing so, we get 18/24 = 3/4. Therefore, the ratio 18 ounces to 3 cups expressed as a fraction in simplest form is 3/4.

The ratio as a fraction in simplest form is 18/24 to get 3/4.

Convert cups to ounces:

3 cups = 3 * 8 ounces

            = 24 ounces

The ratio is 18 ounces to 24 ounces, which can be written as the fraction

= 18/24.

GCD of 18 and 24= 6.

18 ÷ 6 = 3

24 ÷ 6 = 4

So, [tex]\frac{18}{24}[/tex]  simplifies to [tex]\frac{3}{4}[/tex].

Thus, the ratio of 18 ounces to 3 cups in simplest form is 3/4.

Answer:

The decrease in the price will be $4032

The price of the next model is $31968

Step-by-step explanation:

The current model costs $36,000.

The next model of a sports car will cost 11.2% less than the current model

So, decrease in price =[tex]11.2\% \times 36000[/tex]

                                   =[tex]\frac{11.2}{100} \times 36000[/tex]

                                  =4032

So, the price of next model decrease by $4032

So, the price of the next model= 36000-4032 =31968

Hence the price of the next model is $31968

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

Answer:

3 ft

Step-by-step explanation:

To find the width of the cabinet, we can use the formula:

length x width x height = volume

By plugging in the information that the problem gives, we can now solve this problem:

2 ft x 4 ft x width = 24 ft

8 ft x width = 24 ft

width = 24 ft / 8 ft

width = 3 ft

The width of the filing cabinet is found by dividing the volume (24 cubic feet) by the product of the length (2 feet) and height (4 feet), which results in a width of 3 feet.

A filing cabinet with a height of 4 feet and a length of 2 feet has a volume of 24 cubic feet. To find the width of the filing cabinet, we can use the formula for the volume of a rectangular solid: V = l x w x h. Given that V = 24, l = 2, and h = 4, substitute these values into the formula and solve for w:

Volume = length x width x height

24 = 2 x width x 4

width = 24 / (2 x 4) = 24 / 8 = 3.

Therefore, the width of the filing cabinet is 3 feet.

Step-by-step explanation:

The  expression -2a²b⁴÷4ab⁻⁸ is -1/2ab¹² and expression 5w⁴y⁻²÷-15w⁻⁶y² is w¹⁰/3y⁴

An expression is combination of variables, numbers and operators.

The given expression is  -2a²b⁴÷4ab⁻⁸, a≠0, b≠0

We have from properties of exponents that the denominator is multiplied with numerator by changing the sign.

1/aⁿ=a⁻ⁿ

-2a²b⁴/4ab⁻⁸

-1/2a²⁻¹b⁴⁺⁸

-1/2ab¹²

Now the expression is -5w⁴y⁻²÷-15w⁻⁶y²

-5w⁴y⁻²/-15w⁻⁶y²

5w⁴y⁻²/15w⁻⁶y²

1/3w⁴⁺⁶y⁻²⁻²

1/3w¹⁰y⁻⁴

w¹⁰/3y⁴

Hence, the  expression -2a²b⁴÷4ab⁻⁸ is -1/2ab¹² and expression 5w⁴y⁻²÷-15w⁻⁶y² is w¹⁰/3y⁴

11 children approx.

Let's denote the number of children's tickets as x and the number of adult tickets as y

Since each child ticket costs $4.50 and

each adult ticket costs $8.75,

we can set up the following equations based on the given information:

The total number of people=  35:

x + y= 35

The total revenue from ticket sales= $259:

4.50x  + 8.75y = 259

Now we can solve this system of equations to find the values of x and y:

We can start by solving equation 1 for y :

y= 35 - x

Then substitute this expression for y into equation 2:

4.50x + 8.75(35 - x) = 259

Now, solve for x:

4.50x + 306.25 - 8.75x = 259

4.50x - 8.75x = 259 - 306.25

-4.25x = -47.25

Divide both sides by -4.25:

x = (-47.25) / (-4.25)

x = 11.12 approx.

Since the number of children must be a whole number, we can round to the nearest whole number.

So, approximately 11 children were in this group.
