and then repeat that step and you add like terms

then recieve your answer.

Answer:

4x^2 + 12x + 9

Step-by-step explanation:

Actually, you are to find (2x + 3)^2, which is "the square of 2x + 3."

2x + 3 is a binomial.  There is a formula for the square of a binomial:

(a + b)^2 = a^2 + 2ab + b^2

Following this pattern,

(2x + 3)^2 becomes:

[2x]^2 + 2[2x][3] + [3^2], or

4x^2 + 12x + 9

Answer:

Step-by-step explanation:

let $p, $c and $d represents the costs of popcorn, candy and a drink respectively. If the popcorn was three times as  expensive as the candy then;

p = 3c.... 1

If the drink was  twice as expensive as the candy then d = 2c .... 2

If Eva spent a  total sum of $10.50 at the movies, the equation that represents the situation will be p + c + d = $10.50 .... 3

Substituting equation 1 and 2 into 3;

3c + c + 2c = $10.50

6c = $10.50

Hence the equation to represent the situation is 6c = $10.50 where c represents the cost of the candy.

b) To get c from the equation 6c = $10.50, we will simply divide both sides by the coefficient of c i.e 6 as shown

6c/6 = $10.50/6

c = $1.75

Hence the value of c is $1.75

c) The equation representing Eva's drink in terms of the candy is expressed as d = 2c

Substituting c = $1.75 into the equation will give;

d = 2(1.75)

d = 3.5

Hence the cost of Eva's drink is $3.50

Answer: -0.05 mg/cc*h

Step-by-step explanation:

Here we have the relation:

ConcentrationVsTime.

If we want to find the average rate of change, we can find the slope of a line that passes through the extremes of each interval: (tmin, Cmin) and (tmax, Cmax)

The interval for the time is:

0h to 12h.

The interval for the concentration is:

0.7 mg/cc to 0.1mg/cc.

Then we can use the points:

(0h, 0.7mg/cc) and (12h, 0.1mg/cc)

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Then in this case the slope (or rate of change) is:

a = (0.1mg/cc - 0.7mg/cc)/(12h - 0h) = (-0.6mm/cc)/12h = -0.05 mg/cc*h

Answer:

The 45 in snake is the shorter one.

Step-by-step explanation:

Which is shorter, 45 in or 4 1/2 ft?

                                                                                        12 in

Convert 4 1/2 ft into inches by multiplying 4 1/2 ft by --------- = 54 in.

                                                                                          1 ft

Thus, the 45 in snake is shorter than the 54 in one and should b e V's first choice.

The shorter snake will be a corn snake. Then she will get a corn snake.

Conversion means to convert the same thing into different units.

Vivian is getting a pet snake. She is choosing between the ball python and the corn snake. The ball python is 4 1/2 feet long and the corn snake is 45 inches long.

Convert inches into feet. Then the length of a corn snake will be

45 inches = 45/12 feet

45 inches = 3 3/4 feet

Vivian wants the shorter snake.

Thus, the shorter snake will be a corn snake. Then she will get a corn snake.

Answer:

d. Name a ray with endpoint E that is an opposite ray of . Solution a

Answer:

Step-by-step explanation:

so first you need to make a equation

since we are trying to find out the amount of rides we can make that stand for x so..

we can first write it as 2.50x

(x = the numbers of rides)

since the entree fee is 17 dollars but they are two kids we have to times 17 by 2 giving us 34 we can add 34 dollars to the equation

34 + 2.50x

alex and kendra have only $51.50 dollars and they cant spend more then that so that means the whole equation has to equal $51.50

34 + 2.50x = 51.50

since we are trying to find the number of rides we can subtract 34 on both sides giving us

2.50x = 51.50 - 34

2.50x = 17.50

then we solve for x which you can divde 2.50 on both sides

x = 17.50 /2.50

x = 7

Answer:

a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.

The  average height for turkeys at the 90th percentile for weight is 34.554

Of the turkeys at the 90th percentile for weight, roughly the percentage that  would  be taller than 28 inches 79.37%

Step-by-step explanation:

Given that:

For a population of turkeys at a farm, the correlation found between the weights and heights of turkeys is r = 0.64

the average weight in pounds [tex]\overline x[/tex] = 17

the standard deviation of the weight in pounds [tex]S_x[/tex] = 5

the average height in inches [tex]\overline y[/tex] = 28

the standard deviation of the height in inches [tex]S_y[/tex] = 8

Also, given that the weight and height both roughly follow the normal curve

For this study , the slope of the regression line can be expressed as :

[tex]\beta_1 = r \times ( \dfrac{S_y}{S_x})[/tex]

[tex]\beta_1 = 0.64 \times ( \dfrac{8}{5})[/tex]

[tex]\beta_1 = 0.64 \times 1.6[/tex]

[tex]\beta_1 = 1.024[/tex]

To the intercept of the regression line, we have the following equation

[tex]\beta_o = \overline y - \beta_1 \overline x[/tex]

replacing the values:

[tex]\beta_o = 28 -(1.024)(17)[/tex]

[tex]\beta_o = 28 -17.408[/tex]

[tex]\beta_o = 10.592[/tex]

However, the regression line needed for this study can be computed as:

[tex]\hat Y = \beta_o + \beta_1 X[/tex]

[tex]\hat Y = 10.592 + 1.024 X[/tex]

Recall that;

both the weight and height roughly follow the normal curve

As such, the weight related to 90th percentile can be determined as shown below.

Using the Excel Function at 90th percentile, which can be computed as:

(=Normsinv (0.90) ; we have the desired value of 1.28

∴

[tex]\dfrac{X - \overline x}{s_x } = 1.28[/tex]

[tex]\dfrac{X - 17}{5} = 1.28[/tex]

[tex]X - 17 = 6.4[/tex]

X = 6.4 + 17

X = 23.4

The predicted height [tex]\hat Y = 10.592 + 1.024 X[/tex]

where; X = 23.4

[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]

[tex]\hat Y = 10.592 + 23.9616[/tex]

[tex]\hat Y = 34.5536[/tex]

Now; the probability of predicted height less than 34.5536 can be computed as:

[tex]P(Y < 34.5536) = P( \dfrac{Y - \overline y }{S_y} < \dfrac{34.5536-28}{8})[/tex]

[tex]P(Y < 34.5536) = P(Z< \dfrac{6.5536}{8})[/tex]

[tex]P(Y < 34.5536) = P(Z< 0.8192)[/tex]

From the Z tables;

P(Y < 34.5536) =0.7937

Hence,  a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.

The  average height for turkeys at the 90th percentile for weight is :

[tex]\hat Y = 10.592 + 1.024 X[/tex]

where; X = 23.4

[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]

[tex]\hat Y = 10.592 + 23.962[/tex]

[tex]\mathbf{\hat Y = 34.554}[/tex]

Of the turkeys at the 90th percentile for weight, roughly what percent would you estimate to be taller than 28 inches?

i.e

P(Y >28) = 1 - P (Y< 28)

[tex]P(Y >28) = 1 - P( Z < \dfrac{28 - 34.554}{8})[/tex]

[tex]P(Y >28) = 1 - P( Z < \dfrac{-6.554}{8})[/tex]

[tex]P(Y >28) = 1 - P( Z < -0.8193)[/tex]

From the Z tables,

[tex]P(Y >28) = 1 - 0.2063[/tex]

[tex]\mathbf{P(Y >28) = 0.7937}[/tex]

= 79.37%

Step-by-step explanation:

Z score is a score used in statistics to measure by how many standard deviations that the raw score is above or below the mean. A positive z score means the raw score is above the mean and a negative z score means the raw score is below the mean. The z score is given as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Given that:

Mean (μ) = 30.05 inches, standard deviation (σ) = 0.3 inches

For x > 29.95

[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{29.95-30.05}{0.3} =-0.33[/tex]

From the normal distribution table, P(x > 29.95) = P(z > -0.33) = 1 - P(z < 0.33) = 1 -  0.3707 = 0.6293 = 62.93%

Step-by-step explanation:

Coulomb's law is a fundamental tenet of several branches of physics, including electromagnetic, electrostatics, and electronics, and it holds true for both positive and negative charges.

The electrostatic force that exists between two charged particles is described by Coulomb's law, a basic tenet of physics. It asserts that the force between two point charges is inversely proportional to the square of the distance between them and directly proportional to the product of their charges.

Coulomb's law can be expressed mathematically as follows:

F = k(q₁q₂)/r²

Where q₁ and q₂ are the charges' magnitudes, r is the distance between them, and k is the Coulomb constant, F denotes the force acting between the two charges.

The electrostatic constant, commonly referred to as the Coulomb constant, is a proportionality constant that establishes the magnitude of the electrostatic force. Its worth is roughly 8.99 x 109 Nm2/C2.

From m the question we are told that

     The first order differential equation is   [tex]\frac{y' - t}{ t^2 -25} = \frac{e^t}{t-9}[/tex]

Now the first step is to obtain the domain of the differential equation

Now to do that let consider the denominators

  Now generally

                           [tex]t^2 - 25 \ne 0[/tex]                                           side calculation

                   =>     [tex]t\ne \pm5[/tex]                                                      [tex]t^2 - 25 = 0[/tex]

                                                                                          [tex]t = \pm 5[/tex]

Also              [tex]t-9\ne 0[/tex]                                                     [tex]t -9 = 0[/tex]

        =>          [tex]t\ne 9[/tex]                                                            [tex]t= 9[/tex]    

This means that this  first order differential equation is discontinuous at

       [tex]t = -5 , \ \ t = 5 \ \ t = 9[/tex]
