Answer:

x = 2 ± (i)√5  (Answer b)

Step-by-step explanation:

x²-4x+9=0 can be solved in a variety of ways; the first two that come to mind that are also appropriate are (1) completing the square and (2) using the quadratic formula.

Completing the square is fast here:

Rewrite x²-4x+9=0 as   x²-4x                    +9=0

Identify the coefficient of the x term:  it is -4

Take half of that, obtaining -2

Square this result, obtaining 4

Add 4 to   x²-4x                    +9=0, in the blank space in the middle, and then subtract 4:      x²-4x +4          -4         +9=0

Rewrite           x²-4x +4 as the square of a binomial:

                          (x - 2)² - 4 + 9  = 0  →    (x - 2)²  = -5

Take the square root of both sides:       x - 2  = ±√(-5)  =  ± (i)√5

Then x = 2 ± (i)√5

To find how many small cubes can fit inside a larger cube, you need to find the volume of both.

Once you have the volumes, divide the volume of the larger cube, by the volume of the smaller cube.

Volume = L x W x H

Small cube: Volume = 3/4 x 3/4 x 3/4 = 0.421875 cm^3

Large cube: Volume = 3 x 3 x 2 = 18 cm^3

Number of small cubes that can fit: 18 / 0.421875 = 42.67 Cubes.

Since you can't have a partial cube ( 0.67) round down to a whole number:

That means you can fit 42 cubes.

Answer:

the son is 30 and the daughter is 15

Step-by-step explanation:

the mom is 55 in 15 years

100-55=45

45-30=15

15x2=30

Answer:

15 and 5

Step-by-step explanation:

Mother's current age:  40

daughter's age:  d

son's age:  s

son is 2x as old as daughter:  s = 2d

Then, 15 years from now, the sum of their ages will be:

(40 + 15) + (2d + 15) + (d + 15) = 100

or

55 + 15 + 15 + 3d = 100

85 + 3d = 100, or 3d = 15, or d = 5.

Then the son's age is 3(5) = 15 and the daughter's is 5.

To fill the rectangular box with cubes, Ricky can use 144 larger cubes and 0 smaller cubes, resulting in the least number of smaller cubes being 0. The correct answer is option A) 32.

To find the least number of smaller cubes that Ricky can use to fill the rectangular box, we first need to calculate the volume of the box. The volume of the box can be found by multiplying its length, width, and height. In this case, the volume is 8 inches x 4 inches x 4.5 inches = 144 cubic inches.

The larger cubes have a volume of 1 cubic inch, while the smaller cubes have a volume of 1/8 cubic inch. To minimize the number of cubes used, we want to use the larger cubes as much as possible.

We can now calculate the number of larger cubes that can fit in the box. 144 cubic inches / 1 cubic inch = 144 cubes.

Next, we need to fill any remaining space with the smaller cubes. The remaining space can be calculated by subtracting the volume occupied by the larger cubes from the total volume of the box. 144 cubic inches - 144 cubic inches = 0 cubic inches.

Since there is no remaining space, we do not need to use any smaller cubes. Therefore, the least number of smaller cubes that Ricky can use is 0.

So, the correct answer is option A) 32.

Answer:

x = 71°

Step-by-step explanation:

The triangle is clearly an isosceles triangle.

We know that all interior measures of a triangle must add up to 180°.

So: 180° - 38° =  142°

Because it is an isosceles triangle, the other two missing angles must be equal.

142° ÷ 2 = 71°

Answer:

x=71

Step-by-step explanation:

Because of the side being marked 27, you know that the triangle is an isosceles triangle. That means that the other 2 angles would be congruent. To find the sum of the remaining angles, you need to subtract 38 by 180 degrees. (All of the angles in a triangle add up to 180) 180-38=142. Since we already know that the two remaining angles will be congruent, you take 142 and divide by 2 to get the final answer 71.

Answer:

prefixes

Step-by-step explanation:

The exact response will depend a lot on what you learned in your manual and the terms used in it, but the metric system is all based on the base of 10, like the numbers system you use every day.

Unlike the US/Imperial system where there's no clear relation between an inch, a yard and a mile for example, in the metric system everything is related by the factor 10 somehow.

The unit multiplier is also used as a prefix to identify measurements.  Like for meter...

10 meters = 1 decameter

100 meters = 1 hectometer

1000 meters = 1 kilometer

and so on.

The required probability is 1/12 that the first spinner will land on 7 and the second spinner will land on C.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The probability that the first spinner will land on 7

P(7) = favorable outcomes / total outcomes

P(7) = 1/4

The probability that the second spinner will land on C

P(C) = 1/3

As per the given question, the required probability will be as:

The student's question pertains to a survey on students' opinions about a new school mascot. The survey results showed varying levels of support and opposition, which are crucial for decision-making in educational policy. This demonstrates the real-world application of mathematics in understanding public opinion through statistics.

The student's question deals with a survey conducted by student government members to understand the school community's stance on the new school mascot. This survey follows a systematic sampling method by asking every 15th student entering the school. The outcome showed that 57% oppose, 37% are in favor, and 6% have no opinion regarding the new mascot. Such a poll is useful for making decisions related to public policy and ensuring that actions consider community preferences.

Another key component is understanding the methodology behind this survey. If we consider a similar scenario where 600 students are surveyed with 480 opposing new legislation (as mentioned in one of the examples), we could calculate the percentage opposing the legislation and use this to propose actions or influence decision-making processes regarding school policies.

In the context of educational institutions, conducting polls or surveys is a practical way to involve student bodies in decision-making processes, reflecting a democratic practice in school governance. This kind of statistical analysis forms a crucial part of mathematics in the real world, particularly within the fields of statistics and probability.

x=-3, y=6

EXPLANATION

The given equation is

[tex] - 3 + yi = x + 6i[/tex]

We can rewrite this equation as:

[tex]x - yi = - 3 - 6i[/tex]

The two complex number equations are equal therefore their corresponding parts are also equal.

Comparing the real number parts,

[tex]x = - 3[/tex]

Comparing the complex number part,

[tex] - y = - 6[/tex]

y=6.

The value of [tex]\(x\)[/tex] is [tex]\(14\)[/tex]. The correct option is [tex]\(14\)[/tex].

In a right triangle with a 45-degree angle, the sides are related by the special angles of 45-45-90 triangles. In such triangles, the sides are in the ratio [tex]\(1:1:\sqrt{2}\)[/tex].

Given that the height is [tex]\(7\sqrt{2}\)[/tex] and the hypotenuse is [tex]\(x\),[/tex] we can identify the relationship as follows:

[tex]\[ \text{Height} : \text{Base} : \text{Hypotenuse} = 1 : 1 : \sqrt{2} \][/tex]

So, the height is [tex]\(7\sqrt{2}\)[/tex], and the base would be [tex]\(7\sqrt{2}\)[/tex]as well, and the hypotenuse [tex](\(x\))[/tex] would be [tex]\(7\sqrt{2} \times \sqrt{2} = 7 \times 2 = 14\)[/tex].

Therefore, the value of [tex]\(x\)[/tex] is [tex]\(14\)[/tex], and the correct option is:

• [tex]\(14\)[/tex]

The correct answer is [tex]\boxed{14}[/tex]. The value of x is  [tex]\boxed{14}[/tex].

To determine the value of [tex]\( x \)[/tex], we need to consider the given options and the context of the question, which involves the square root of 2. The options provided are [tex]\( 7 \), \( 7\sqrt{2} \), \( 14 \), and \( 14\sqrt{2} \).[/tex]

Let's analyze the options:

1. [tex]\( 7 \)[/tex] is a straightforward integer.

2. [tex]\( 7\sqrt{2} \) is \( 7 \)[/tex] times the square root of 2, which is an irrational number approximately equal to [tex]\( 1.414 \)[/tex].

3.[tex]\( 14 \) is \( 7 \)[/tex] times [tex]\( 2 \)[/tex], which is a simple integer multiplication.

4. [tex]\( 14\sqrt{2} \) is \( 14 \)[/tex] times the square root of 2.

Given that the question is asking for the value of [tex]\( x \)[/tex] and the options involve multiples of [tex]\( 7 \)[/tex] and [tex]\( 14 \)[/tex], it is reasonable to suspect that the answer might involve the square root of 2, since it is the only mathematical operation present in all the options.

However, without additional context or a mathematical equation to solve for [tex]\( x \)[/tex], we cannot definitively determine which of these options is correct based solely on the information given. In mathematics, problems involving square roots typically require an equation or a geometric representation to provide a clear path to the solution.

Since the question does not provide an equation or additional context, we must rely on the principle that the most straightforward answer is often correct when dealing with multiple-choice questions. In this case, the simplest option that does not involve an irrational number is [tex]\( 14 \)[/tex].

Therefore, without further information, the most logical and simple choice is [tex]\( 14 \)[/tex], as it is a whole number and does not introduce the complexity of an irrational number like [tex]\( \sqrt{2} \)[/tex].

Thus, the final answer is [tex]\boxed{14}[/tex].

Final answer:

To find the length of the wall on the new blueprint with a scale of 1 cm = 3 ft, a proportion can be used. The length of the wall on the new blueprint would be 0.75 ft.

Explanation:

To find the length of the wall on the new blueprint with a scale of 1 cm = 3 ft, we can use a proportion.

In the original blueprint with a scale of 1 cm = 4 ft, the length of the wall is 9 cm. Let's let x represent the length of the wall on the new blueprint.

Set up the proportion: 1 cm/4 ft = x cm/3 ft

Cross multiply: 1 * 3 = 4 * x

Solve for x: x = 3/4

Therefore, the length of the wall on the new blueprint would be 3/4 ft or 0.75 ft.

Step-by-step explanation:

We can write a ratio, dollars over bottles of water

7             28

-------- = ----------

4              x

Using cross products

7x = 4*28

Divide each side by 7

7x/7 = 4*28/7

x = 4 * 4

x = 16

From the function sin(x+y) - sin(x-y) = 2f(x)sin(y), we can deduce that f(x) = cosx

But sin(x + y) = sinxcosy + cosxsiny.

Also, sin(x - y) = sinxcosy - cosxsiny..

Hence:

sin(x+y) - sin(x-y)

= sinxcosy + cosxsiny - (sinxcosy - cosxsiny)

=  sinxcosy -  sinxcosy + cosxsiny + cosxsiny

= 2cosxsiny

2cosxsiny = 2f(x)sin(y)

Hence, f(x) = cosx

Answer:

1.25

Step-by-step explanation:

Hopefully that's right. It's a bit hard to see separation

The interquartile range of Harry's collected data set is 1.25 hours.

To calculate the interquartile range (IQR) for the given data set, we must first arrange the data in ascending order, which is already done in this case. The data set is .5, .5, .75, .75, .75, 1, 1, 1, 1, 1.5, 1.5, 2, 2, 3, 4. The next step is to find the medians of the lower and upper halves of the data set to locate the first quartile (Q1) and the third quartile (Q3).

Since the data set has 15 numbers, the median (which is also Q2) would be the 8th value, which is 1.

For Q1, we take the lower half, which consists of the first 7 numbers. The median of this subset is the fourth value: 0.75.

For Q3, we consider the upper half, which consists of the last 7 numbers. The median of this subset is the fourth value: 2.

Now, calculate the IQR by subtracting Q1 from Q3: IQR = Q3 - Q1 = 2 - 0.75 = 1.25.

Therefore, the interquartile range of the data set that Harry collected is 1.25 hours.
