Answer:

The relation y=2x+8 is a function because the two different output values of the function have the one unique input value.

Step-by-step explanation:

The given relation is y=2x+8.

It is required to determine the relation is a function.

This solution can be obtained by using the concept of function. First write the given relation y=2x+8 and determine whether the given relation is a function.

Step 1 of 1

The given relation is y=2x+8.

This relation shows that the two different output values of the function have one unique input value and this relation is a linear function.

Hence, the relation is a function.

Answer:

NO

Step-by-step explanation:

The new coordinates will be ( 7,5) and (11,9) , Option A is the correct answer.

The reciprocal function is the inverse of the function, such that 1/ f(x) is the reciprocal of f(x).

The given linear function has pairs of points

(5,7) and (9,11)

The reciprocal of this will be

interchanging of the coordinates

Therefore the new coordinates will be

( 7,5) and (11,9)

Option A is the correct answer.

6. The system of equations has no solution.

7. B. Tables - 15 lbs, chairs - 3.5 lbs.

The values of x and y that makes two equations equal is the solution of a system of equations.

6. 3x + 4y = 12 --> eqn. 1

y = 3 - 3/4x --> eqn. 2

Substitute y = (3 - 3/4x) into eqn. 1 to find x:

3x + 4(3 - 3/4x) = 12

3x + 12 - 3x = 12

12 = 12 [unable to solve further for x]

This means that the system of equations has no solution.

7. t = tables

c = chairs

3t + 5c = 62.5 --> eqn. 1

3t + 2c = 52 --> eqn. 2

Subtract

3c = 10.5

c = 3.5 [chairs]

Substitute c = 3.5 into eqn. 2

3t + 2(3.5) = 52

3t + 7 = 52

3t = 52 - 7

The confidence interval or the mean noise level is (108.17,150.23) and sample standard deviation is 12.52.

Given noise levels:108,133,140,129,136. and confidence level 98%.

We have to find the confidence level and the sample standard deviation of the given data.

Confidence level=98%.

n=5

Sample standard deviation=[tex]\sqrt{(x-x bar)^{2} /n-1}[/tex]

=[tex]\sqrt{626.8/4}[/tex]

=[tex]\sqrt{156.7}[/tex]

=12.52

critical t value at 98% confidence level with degree of freedom(5-1) is 3.747

Standard error= critical t*s/[tex]\sqrt{n}[/tex]

Standard error is the difference between the real values and calculated values.

=3.747*12.52/[tex]\sqrt{5}[/tex]

=46.91/2.23

Step-by-step explanation:

Using the equation (instead of the graph....my answer got deleted for using the graph instead of the equation)

When the ball leaves fingers x = 0 :

a)  -1/25 ( 0-10)^2 + 11 =   7 ft

b)    max height will be at - b/2a

        -1/25 ( x^2 -20x +100 ) + 11       <====expand

         -1/25 x^2 + 4/5x +7        a = -1/25       b= 4/5

                then - b/2a =  -  4/5 / (2* -1/25) = 10=x

                     sub in this value of x into the equation to find max height = 11ft

Answer: a monomial has one term, binomial has 2 terms, and trinomial has 3.

Step-by-step explanation:

using a bit of greek and latin roots, we can observe that all 3 terms have the same suffix of nomial in them. From this, we know that mono means one, bino means two, and tri means 3. Fun fact, there's also polynomial (if you did or didn't know), which is multiple terms more than 3.

Binomial distribution will be used to know the probability that the total weight of the samples will exceed 530 pounds.

It is given that the rocket that will return the rock and soil samples to Earth cannot lift off if the total weight of the samples from the rovers exceeds 530 pounds.

In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p). A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution. The binomial distribution is the basis for the popular binomial test of statistical significance.

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

is 1×7 on top, and

3×10 on the bottom.

= (1×7)/(3×10)

= 7/30

7/30 cannot be simplified, so that is the answer.

The proper sequence of steps in implementing the model in Excel presented in the textbook is option b which is organize the data, represent the decision variables, represent the objective function, represent the constraints and represent the bounds on the decision variables.

Given process of implementing the model in Excel and we have to choose the correct process.

The process of implementing the model in Excel is as under:

1) Organize the data: In excel, to organize the data we have to put similar items in the same column. We have to design the data so that all rows have similar items in the same column. We have to keep a range of data separate and leave at least one blank column and one blank row between a related data range.

2) Represent the decision variables: Now we have to represent the decision variables according to which logical function performs tasks.

3)Represent the objective function: It is important because on the basis of this all the logical function perform tasks.

4) Represent the constraints: In excel when we are using solver we have to now represent the constraints of the objective function.

5) Represents the bounds on the decision variables.

Hence the proper sequence of steps in implementing the model in excel is Organize the data, represent the decision variables, represent the objective function, represent the constraints, and represent the bounds on the decision variables.

Figures are missing in the question.

The images below shows the missing figures of question.

For congruent figures, we need the same shape, same area, and inverse direction.

Congruent figures have congruency. That seems simple enough, but congruent figures need not be turned the same way or face the same direction to be congruent.

In the case of geometric figures, line segments with the same length are congruent and angle with the same measure are congruent.

In elementary geometry the word congruent is often used as follows. The word equal is often used in place of congruent for these objects.

In this sense, two plane figures are congruent implies that their corresponding characteristics are "congruent" or "equal" including not just their corresponding sides and angles, but also their corresponding diagonals, perimeters, and areas.

The figure in option D satisfies all these conditions. Hence, Option D is correct.

Inequality is a statement of an order relationship between two numbers or algebraic expressions

In this vase, with a number line with two points opposite from each other on a number line, the middle of it is always going to be 0.  

Therefore, both points are the same distance away from 0 just in opposite directions.

That means point Q is always going to equal the negative of point P. An example of this is if point p equals 5, point p equals -5.

Answer:

A, C, and D

Step-by-step explanation:

A) (4x + 3) (2x + 6) is equal to 8x² + 30x + 18 because when you multiply two binomials, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, (4x + 3) (2x + 6) can be rewritten as (4x)(2x) + (4x)(6) + (3)(2x) + (3)(6). This can further be simplified to 8x² + 24x + 18.

C) 2(4x² + 15x + 9) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 2(4x² + 15x + 9) can be rewritten as 2(4x²) + 2(15x) + 2(9). This can further be simplified to 8x² + 30x + 18.

D) 4(2x² + 7x + 4) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 4(2x² + 7x + 4) can be rewritten as 4(2x²) + 4(7x) + 4(4). This can further be simplified to 8x² + 28x + 16.
