which number is irrational an integer and a real number?

A.0
B. there is no such number
C.-4/2
D. 4

Answer:

Yes, I can help you simplify that expression.

Starting with the expression:

p(p-2) x (2/p)

You can simplify it by first multiplying the terms in the first set of parentheses:

p(p-2) = p^2 - 2p

Then you can rewrite the second term as a fraction with a common denominator of p:

2/p = 2p/p^2 = 2/p^2

Now the expression becomes:

(p^2 - 2p) x (2/p^2)

Next, you can factor out a 2 from the first set of parentheses:

2p(p - 1) x (2/p^2)

Finally, you can simplify the expression by canceling out the p in the second fraction:

2(p - 1)

So the simplified expression is 2(p - 1).

Answer:

I’m sorry I don’t know the answer

Step-by-step explanation:

Answer:

7/32/1/6

you separate the fractions

7/32÷1/6

change the division sign to multiplication then you take the denominator up and the numerator down.

7/32×6/1

then multiply

42/32

reduce to the lowest term

21/16

Step 1: Isolate the Sin Operator

\(8 sin(\frac{\pi }{6} x)=2\\sin(\frac{\pi }{6} x)=0.25\\\\\)

Step 2: Use Inverse Sin(arcsin) to isolate the term with the x variable

Note that since trig functions have 2 general solutions, this will give us one of our general solutions.

\(x=\frac{6 arcsin(0.25)}{\pi } =0.48\)

x₁= 0.48

Solving for x₂

Use the period identity for Sin Functions

\(sin(x)=sin(\pi -x)\)

X in this case is arcsin(0.25)

\(\frac{\pi }{6} x=\pi -arcsin(0.25) = 5.52\)

So our two general solutions are 0.48 and 5.52

Step 3: Period

Trig Functions have periodic behavior and this function period is

\(\frac{2\pi }{1} (\frac{6}{\pi } )= 12\)

So our general solutions are

0.48±12k, where k is an integer

5.52±12k, where k is an integer

Let k=1, and we get our next set of solutions:

12.48 and 17.52

So our answer is 0.48,5.52,12.48,17.52

3y = 4x + 2 is a linear equation that satisfies the graph.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Few coordinates of a linear function to make the equation of line we need only two coordinates.

general formula for linear equation is y = mx + c

where, m = slope

c = constant

General formula for slope m = (y₂ - y₁)/(x₂ -x₁)

Since graph passes through the points(3, 6) and (0, 2)

Slope m = (2 - 6)/ (0 - 3)

m = -4/-3 = 4/3

Thus, equation of line will be

y = 4/3x + c

Since the Line passes through (0, ,2 ) these point will satisfy the above equation

2 = 4/3 * 0 + c

=> c = 2

substitute the values

y = 4/3x + 2

3y = 4x +6

Therefore, equation of line that relates with the graph is 3y = 4x + 6.

Answer

The two segments aren't congruent.

Explanation

The two segments given that we are asked to check if they are congruent are

(2, 3), (3, -3)

and

(-1, 4), (-4, -1)

The only way to know if the segments are congruent is from the values of the slopes of the two segments. If the two segments are congruent, the slopes will be equal.

The slope of a line or segment that has two coordinates given is calculated as

Slope = (Change in y)/(Change in x)

For (2, 3), (3, -3),

Change in y = -3 - 3 = -6

Change in x = 3 - 2 = 1

Slope = (-6/1) = -6

For (-1, 4), (-4, -1)

Change in y = -1 - 4 = -5

Change in x = -4 - (-1) = -4 + 1 = -3

Slope = (-5/-3) = (5/3) = 1.667

The two slopes are evidently not equal, hence, the two segments aren't congruent.

Step-by-step explanation:

the area of a rectangle is

length × width

the perimeter of a rectangle is

2×length + 2×width

so,

length×width = 48 cm²

2×length + 2×width = 28 cm

length + width = 14 cm

length = 14 - width

we use this in the first equation :

(14 - width) × width = 48

14×width - width² = 48

-width² + 14×width - 48 = 0

a quadratic equation

ax² + bx + c = 0

has the general solution

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = width

a = -1

b = 14

c = -48

width = (-14 ± sqrt(14² - 4×-1×-48))/(2×-1) =

= (-14 ± sqrt(196 - 192))/-2 =

= (-14 ± sqrt(4))/-2 =

= (-14 ± 2)/-2 =

= 7 ± 1

width1 = 7 + 1 = 8 cm

width2 = 7 - 1 = 6 cm

length1 = 14 - width1 = 14 - 8 = 6 cm

length2 = 14 - width2 = 14 - 6 = 8 cm

so, we see, one of them must be 8 cm, and the other 6 cm.

let's length be the longer side, so

length = 8 cm

width = 6 cm

Step-by-step explanation:

The bus that is the most consistent, given the data collected on travel times to school from two groups of students is C Bus 18, with a range of 10

To determine which bus is the most consistent, we should use the interquartile range (IQR) as the measure of variability. The IQR measures the spread of the middle 50% of the data, which makes it less sensitive to outliers compared to the range.

Bus 47:

Median (Q2): 16

Q1: 10

Q3: 22

IQR = Q3 - Q1 = 22 - 10 = 12

Bus 18:

Median (Q2): 12

Q1: 8

Q3: 18

IQR = Q3 - Q1 = 18 - 8 = 10

Bus 18 has a smaller IQR than Bus 47 (10 vs. 12), which means the travel times for Bus 18 are more consistent.

Note: Figures might be different due to options being for different variant but Bus 18 is the most consistent.

Step-by-step explanation:

None of these can be divided by anything except themselves and 1.

Answer:

growth

140%

Step-by-step explanation:

The function f(x) is an exponential growth function as f(x) increases when x increases.

The percent rate of change of the function f(x) is 201.6%.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 0.6 \((2.4)^x\)

For x = 1,

f(1) = 0.6 x 2.4 = 1.44

For x = 2,

f(2) = 0.6 x 2.4² = 0.6 x 5.76 = 3.456

For x = 3,

f(3) = 0.6 x 2.4³ = 0.6 x 18.824 = 8.2944

We see that,

As the value of x increases, the value of f(x) increases.

f(x) is an exponential growth function.

Now,

The percentage rate of change of function f(x).

= (f(2) - f(1)) / (2 - 1) x 100

= (3.456 - 1.44) x 100

= 2.016 x 100

= 201.6 %

Thus,

f(x) is an exponential growth function.

f(x) percent rate of change is 201.6%

Answer:

he total number of people who use at least two facilities is 4 + 45 = 49

Step-by-step explanation:

To find the number of people who use at least two facilities, we can find the number of people who use all three facilities and add the number of people who use only two facilities.

The number of people who use all three facilities is 4, and the number of people who use only two facilities is 27 + 23 + 31 - 3 * 4 = 45.

Therefore, the total number of people who use at least two facilities is 4 + 45 = 49.

The simplification of the expressions in the question using the rules of indices are as follows;

An index or indices is the power by which a number or variable or expression raised.

1.) 6·e⁰ + (11·f)⁰ - 5/g⁰

6·e⁰ + (11·f)⁰ - 5/g⁰ = 6 × 1 + 1 - 5/1

6 × 1 + 1 - 5/1 = 6 + 1 - 5 = 2

1/((125 + 81)/(81×125)) = (81 × 125)/(125+81) = 10125/209

10125/206 = 49 + 31/206

(3⁻⁴ + 5⁻³)⁻¹ = \(49 \frac{31}{206}\)

3.) (3⁻⁴ + 5⁻³)⁻²

(3⁻⁴ + 5⁻³)⁻² = 1/((1/3⁴ + 1/5³)²)

1/((1/3⁴ + 1/5³)²) = 1/((1/81 + 1/125)²)

1/((1/81 + 1/125)²) = 1/(((125 + 81)/(81 × 125))²)

1/(((125 + 81)/(81 × 125))²) = 1/((206/10125)²)

1/((206/10125)²) = (10125)²/(206)² = 102515625/42436

102515625/42436 = 2415 32685/42436

The sampling method used by the restaurant manager allows for efficient data collection and a representative sample, it may introduce bias and lacks randomization.

Based on the information provided, we can identify the following statements that are true about the sampling method used by the restaurant manager to evaluate customer satisfaction with the new smoothie:

1. The manager uses systematic sampling: The manager surveys every other customer who orders the new smoothie. This systematic approach involves selecting every second customer, providing a consistent and organized sampling method.

2. The sample is representative: By surveying every other customer who orders the new smoothie, the manager ensures that the sample includes a variety of customers, reflecting the customer population as a whole.

3. The sample size may be smaller than the total customer base: Since the manager surveys every other customer, the sample size may be smaller compared to surveying every customer. This allows for efficient data collection and analysis.

4.The sampling method may introduce bias: The manager may inadvertently introduce bias by only surveying every other customer. Customers who are skipped in the survey may have different preferences or opinions, leading to a potential bias in the results.

5. The sampling method lacks randomization: Randomization is not employed in this sampling method, as the manager systematically selects customers. This could potentially introduce bias or exclude certain types of customers from the sample.

The x-intercepts of the graph of the equation are (8,0) and (-6,0).

What are intercepts?

A point on the y-axis known as an intercept is where the line's slope passes.

X-intercept and Y-intercept are the two main intercepts. The line's x-intercept and y-intercept are located where the line crosses the x and y axes, respectively.

Now, in order to find the x- intercepts, we need to put y=0 because at that point the line crosses the x- axis and therefore, y=0 at that point.

So,

x^2-2x+(0)^2-3(0)=48

⇒x^2-2x=48

⇒x^2-2x-48=0

⇒x^2+6x-8x-48=0

⇒x(x+6)-8(x+6)=0

⇒(x-8)(x+6)=0

So, x= 8,-6

Hence, the x-intercepts of the graph of the equation are (8,0) and (-6,0).

The 2 horizontal lines are parallel as given ion the problem.

The x + 97 angle is congruent to the right angle.

x + 97 = 90

x = -7

Answer:

Congurent triangles are those which map onto them selves perfectly. This means they share the same angle measurements and side lengths. Therefor we can figure out the side lengths by using the information in both triangles.

AD=5x+11

in the congurent triangle, the corresponding side equals:

CM=7x-3

CM and AD are congurent triangles meaning their sidelengths equal the same. Therefore...

5x+11=7x-3

Now we just solve to find the length of AD and CM (equal lengths)

5x+11=7x-3

11=2x-3

14=2x

7=x

x=7

If x=7 then we can plug it in for AD to find the side length.

5(7)+11=46

Notice that CM equals the same 7(7)-3=46

This is because... they are congruent triangles.

These rules also apply for all angle measurements of congruent triangles:

The m<v is equal to the meaasure of E (corresponding angles in congrurent triangles are equal)

We already astablished what x was (x=7) meaning if we find the measure of E then we have the measure of V sicne they are corresponding angles in a congrurent triangle.
