Step-by-step explanation:

I believe you answer would be D

Answer:

None of them.

Step-by-step explanation:

you want to find the least value of x for which f(x)>g(x). Then replacing both expressions we have

[tex]4x>5x+2\rightarrow -2>5x-4x=x[/tex] . This means that for f to be greater than g, x should be less than -2. Since we are considering x>0, given that it represents years (which are always positive), the question does not have a correct answer.

Answer:

Option B [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

we know that

[tex]sin(2\theta) = 2 sin(\theta) cos(\theta)[/tex]

In this problem we have

[tex]cos(\theta)=\frac{4}{5}[/tex]

Find the value of [tex]sin(\theta)[/tex]

Remember that

[tex]sin^{2} (\theta)+cos^{2} (\theta)=1[/tex]

substitute the value

[tex]sin^{2} (\theta)+(\frac{4}{5})^{2}=1[/tex]

[tex]sin^{2} (\theta)=1-\frac{16}{25}[/tex]

[tex]sin^{2} (\theta)=\frac{9}{25}[/tex]

[tex]sin(\theta)=\frac{3}{5}[/tex]

Find the value of [tex]sin(2\theta)[/tex]

[tex]sin(2\theta) = 2 (\frac{3}{5})(\frac{4}{5})[/tex]

[tex]sin(2\theta) = \frac{24}{25}[/tex]

Final answer:

A table can simultaneously display yes/no (Boolean) and numeric data. Yes/No fields in databases are often checkboxes representing binary choices, while other columns can store numeric data. The data types assigned to these fields determine how they are sorted and displayed in the table.

Explanation:

Yes, it is entirely possible for a table to display both yes/no and numeric data at the same time. The yes/no data is often referred to as binary, Boolean, or Yes/No datatype, and in databases, it commonly appears as a checkbox. These Yes/No fields contain only two possible values, such as Yes/No, True/False, or On/Off. On the other hand, the numeric data represents quantitative information that can be measured and written down with numbers.

Tables are quite versatile and can conveniently organize complex numerical information, alongside qualitative categories, in a structured format using rows and columns. For example, a table can be used to compare different models of a product using criteria represented by both text and numbers, such as product features ('Yes' for having a feature and 'No' for not having it) and specifications like price or weight (numeric data).

It's important to keep in mind that when designing a database, every field is assigned a datatype based on what type of data it holds. For fields containing text, a 'text' datatype is used; whereas for fields containing numeric values, a 'number' datatype is chosen. The datatype affects how the data is sorted and processed within the table.

The point (-3,4) when reflected across the x-axis results in new coordinates (-3, -4), changing the sign of the y-coordinate.

The question asks for the new coordinates of a point after being reflected across the x-axis. Reflecting a point across the x-axis changes the sign of the y-coordinate but leaves the x-coordinate unchanged. Therefore, if we have a point (-3, 4) and we reflect it across the x-axis, the x-coordinate remains -3, and the y-coordinate, which is 4, will become -4, resulting in the new coordinates (-3, -4).

I believe the answer is A.

Answer:

The correct answer is first option

X = 10.53

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = opposite side/Adjacent side

From the figure we can see a right angled triangle, with one angle is  29 degree, one side is 19 and hypotenuse is x

To find the value of x

Tan θ = Opposite side/Adjacent side

Tan 29 = 19/x

x = 19 * Tan 29

 = 19 * 0.5543

 = 10.53

Therefore the correct answer is first option

Answer:

Final answer is approx [tex]x=34.28[/tex].

Step-by-step explanation:

Using given information in the picture, we need to find the missing value of x.

Apply formula of tangent function which is :

[tex]\tan\left(\theta\right)=\frac{opposite}{adjacent}[/tex]

[tex]\tan\left(29^o\right)=\frac{19}{x}[/tex]

[tex]0.554309=\frac{19}{x}[/tex]

[tex]x=\frac{19}{0.554309}[/tex]

[tex]x=34.2769105319[/tex]

Hence final answer is approx [tex]x=34.28[/tex].

The answer is:

The fourth option,

[tex](f-g)(x)=11x[/tex]

To solve the problem, we must remember the following property of the functions:

Subtraction of functions:

We have that,

[tex](f-g)(x)=f(x)-g(x)[/tex]

We are given the functions:

[tex]f(x)=4x+3[/tex]

and

[tex]g(x)=3-7x[/tex]

So, calculating we have:

[tex](f-g)(x)=f(x)-g(x)[/tex]

[tex](f-g)(x)=(4x+3)-(3-7x)[/tex]

[tex](f-g)(x)=4x+3-3+7x[/tex]

[tex](f-g)(x)=4x+7x+3-3=11x[/tex]

Hence, the answer is the fourth option,

[tex](f-g)(x)=11x[/tex]

Have a nice day!

Answer:

(D) (f-g)(x) = 11x

Step-by-step explanation:

You have:

f(x) = 4x + 3

g(x) = 3 - 7x

You want to do f(x) - g(x)... you simply do the operation on their definition...

f(x) - g(x) = 4x + 3 - (3 - 7x) = 4x + 3 - 3 + 7x = 11 x + 0

So, (f-g)(x) = 11x

You can verify it by placing a value for x in both equations.  Let's take x = 3

f(x) = 4x + 3 = 4(3) + 3 = 15

g(x) = 3 - 7x = 3 - 7(3) = -18

f(x) - g(x) = 15 - -18 = 33

(f - g)(x) = 11x = 11 (3) = 33

Yes, (f(x) - g(x)) = (f - g)(x) = 33

For this case we must solve the following questions:

Question 1:

We must solve the following quadratic equation:

[tex]x ^ 2 + 1 = 0[/tex]

We subtract 1 from both sides of the equation:

[tex]x ^ 2 + 1-1 = -1\\x ^ 2 = -1[/tex]

We apply square root to eliminate the exponent:

[tex]x = \pm \sqrt {-1}[/tex]

The solution is not real.

[tex]x_ {1} = + i\\x_ {2} = - i[/tex]

Answer:

[tex]x_ {1} = + i\\x_ {2} = - i[/tex]

Option D

Question 2:

We must solve the following quadratic equation:

[tex]x ^ 2-10x + 24 = 0[/tex]

We factor the equation, that is, we must look for two numbers that when multiplied give as result 24 and when summed with -10. These numbers are -6 and -4:

[tex]-6-4 = -10\\-6 * -4 = 24\\(x-6) (x-4) = 0[/tex]

The roots are:

[tex]x_ {1} = 6\\x_ {2} = 4[/tex]

ANswer:

[tex]x_ {1} = 6\\x_ {2} = 4[/tex]

Option D

Question 3:

We must complete squares of the following expression:

[tex]x ^ 2-18x = 7[/tex]

We add [tex](\frac {b} {2}) ^ 2 = (\frac {-18} {2}) ^ 2 = (- 9) ^ 2[/tex]

Then:

[tex]x ^ 2-18x + (- 9) ^ 2 = 7 + (- 9) ^ 2\\x ^ 2-18x + (- 9) ^ 2 = 7 + 81\\x ^ 2-18x + (- 9) ^ 2 = 88\\(x-9) ^ 2 = 88[/tex]

Then, to complete the square, add it to both sides [tex](-9) ^ 2 = 81[/tex]

The vertex of the shaded region are

A(0,0), B(4,000,0),C(2,000,4,000), D(0,6,000)

Substitute the value of x and the value of y of each vertex in the z equation to find the solution

case A) A(0,0)

[tex]z=10(0)+6(0)=0[/tex]

case B)  B(4,000,0)

[tex]z=10(4,000)+6(0)=40,000[/tex]

case C)  C(2,000,4,000)

[tex]z=10(2,000)+6(4,000)=44,000[/tex]

case D)  D(0,6,000)

[tex]z=10(0)+6(6,000)=36,000[/tex]

Answer:

James is 1 meter and 63 centimeters tall

Step-by-step explanation:

James is 1 meter and 63 centimeters tall. The first step will be to subtract 1 from his height;

1.63 - 1 = 0.63 meters

The 1 subtracted is equivalent to 1 meter. The next step is to convert the remaining height in meters to centimeters by multiplying by 100;

0.63 * 100 = 63 centimeters

We can thus say, James is 1 meter and 63 centimeters tall or equivalently 163 centimeters tall

Null (not defined)

Step-by-step explanation:

We cannot divide by 0; division by zero (0) is undefined.  If you take calculus later on, you'll "take limits" and will occasionally end up at 0/0.  Sometimes it's possible to find a numerical value; more often, it's not.

When x=-2

f(x) =3(-2) -12 =-6-12=-18

When x=2

f(x) = 3(2)-12=6-12=-6

So For the domain (-2,2)

Range of the function f(x) is (-18,-6)

So (-18 ,-6). is your answer.

Hope it helps....

Regards,

Leukonov/Olegion.

The range of the function f(x) = 3x - 12 for the domain (-2, 2) is (-18, -6). This is determined by finding the function's output at x = -2 and x = 2, which are the endpoints of the specified domain.

The question asks for the range of the function f(x) = 3x - 12 given the domain (-2, 2). To determine the range, we calculate the output values of the function using the endpoints of the domain.

For the lower endpoint of the domain, x = -2: f(-2) = 3(-2) - 12 = -6 - 12 = -18.

For the upper endpoint of the domain, x = 2: f(2) = 3(2) - 12 = 6 - 12 = -6.

Since the function is a straight line (which is continuous and has a constant rate of change), the range over the interval (-2, 2) is all values between f(-2) and f(2), though not including the endpoints since the domain is open. Thus, the range is (-18, -6).

The correct answer is B. (-18, -6).

Answer:

(144) is the homogeneous mixture

Answer:

Ac = 144

Step-by-step explanation:

From the figure we can see two similar triangles,Ratio of sides of similar triangles are equal.

To find the value of x

From the figure we can write,

7/84 = x/(156 - x)

1/12 = x/(156 - x)

156 - x = 12x

13x = 156

x = 156/13 = 12

To find the value of AC

AC = 156 - x

 = 156 - 12

 = 144

Therefore AC = 144

Answer:

1260

Step-by-step explanation:

Round 0.65 to 0.7 and round 1754 to 1800. To get 1260, I recommend an easy way to do this. I would take 18 and multiply it by 7, giving us 126. Because it was supposed to be 0.7, not 7, we multiply by 10 because 7/10 is 0.7. This gives us 126 times 10 which equals 1260.

By rounding 0.65 to the nearest tenth and 1754 to the nearest hundred, we get 0.7 and 1800 respectively. Multiplying these gives an estimated product of 1260.

To estimate the answer by rounding the first number to the nearest tenth and the second number to the nearest hundred, we start by determining the rounded numbers. The number 0.65 rounded to the nearest tenth is 0.7, and the number 1754 rounded to the nearest hundred is 1800. Multiplying these two rounded numbers together gives us 0.7 × 1800 = 1260.

Therefore, by rounding before multiplying, we can estimate that 0.65 × 1754 is approximately 1260. This estimation technique helps simplify calculations and is very useful when an exact answer is not required, especially when dealing with large numbers or calculations that would otherwise be complex.

Answer:

[tex]3 \sqrt[3]{162} = 3 \sqrt[3]{27} \sqrt[3]{6} = 3(3 \sqrt[3]{6} ) = 9 \sqrt[3]{6} [/tex]

Final answer:

The simplest form of 3 cube root of 162 is 9 cube root 2, with a=9 and b=2 after factoring out the perfect cube within 162.

Explanation:

The student has asked about simplifying the expression 3 cube root of 162 into the form a3 cube root b. The cube root of 162 can be simplified by factoring out cubes. The number 162 is equal to 2 * 81, where 81 is a perfect cube (3³). Thus, we can rewrite 162 as 2 * 3³. When taking the cube root, the cube root of 3³ is 3, and it comes out of the cube root symbol leaving us with 2 inside the cube root. Multiplying this by 3 outside the cube root, we get:

3 * 3 cube root 2 = 9 cube root 2

Therefore, the expression in its simplest form is 9 cube root 2, which follows the format a3 cube root b with a=9 and b=2.

Answer:

Step-by-step explanation:

If two events are independent, the probability of both happening are:

P(A and B) = P(A) × P(B)

In this case, if rain and lightening were independent:

P(rain and lightening) = P(rain) × P(lightening)

P(rain and lightening) = 0.45 × 0.45

P(rain and lightening) = 0.2025

However, we're told that P(rain and lightening) is 0.25, not 0.2025.

Since 0.2025 ≠ 0.25, the events are not independent, so they are dependent.
