Answer:

The solutions to the equation (x + 1)(x - 4) = 0 are x = -1 and x = 4.

Step-by-step explanation:

To solve the equation (x + 1)(x - 4) = 0 using the zero product property, we need to set each factor equal to zero and solve for x:

x + 1 = 0 or x - 4 = 0

Solving for x in the first equation, we get:

x + 1 = 0

x = -1

Solving for x in the second equation, we get:

x - 4 = 0

x = 4

Therefore, the solutions to the equation (x + 1)(x - 4) = 0 are x = -1 and x = 4.

1. [tex]dy/dt = ky[/tex] 2. [tex]dy/dt = -ky[/tex] 3. [tex]ln|y| = kt + C1[/tex] are solutions for the differential equation.

1. The differential equation for an animal whose weight is increasing at a rate proportional to its weight can be represented as:

[tex]dy/dt = ky[/tex]

where dy/dt is the rate of change of weight with respect to time, k is the proportionality constant, and y is the weight of the animal.

2. The differential equation for a bacteria population that is shrinking at a rate proportional to its population size can also be represented as:
[tex]dy/dt = -ky[/tex]

Here, dy/dt is the rate of change of population with respect to time, k is the proportionality constant, and y is the population size. The negative sign indicates that the population is shrinking.

3. To solve the differential equation dy/dt = ky using separation of variables, follow these steps:

Step 1: Separate the variables, with y terms on one side and t terms on the other:

[tex](dy/y) = k(dt)[/tex]

Step 2: Integrate both sides of the equation:

[tex]∫(1/y) dy = ∫k dt[/tex]

Step 3: After integrating, you'll get:

[tex]ln|y| = kt + C1[/tex]

where C1 is the constant of integration.

Step 4: To solve for y, take the exponent of both sides:

[tex]y(t) = e^(kt + C1) = e^(kt) * e^C1[/tex]

Since e^C1 is a constant, we can replace it with another constant, C:

[tex]y(t) = Ce^(kt)[/tex]

This is the general solution to the differential equation [tex]dy/dt = ky[/tex], where C is the integration constant, and it can be determined using initial conditions if provided.

Step-by-step explanation:

since each cube measure 1/2 of a centimeter on one side, the dimension is calculated first

length = 2 x 1/2 cm

width = 3 x 1/2 cm

height = 3 x 1/2 cm

The required standard form of the function f(x) is 3x² - 48x + 32.

The vertex form of a quadratic function is:

f(x) = a(x - h)² + k

Where (h, k) is the vertex of the parabola and a is a coefficient that determines the shape of the parabola.

In the given function we can see that the vertex is at (8, -160) and a is 3. So we have:

f(x) = 3(x - 8)² - 160

Expanding the square:

f(x) = 3(x - 8)(x - 8) - 160

f(x) = 3(x² - 16x + 64) - 160

Distributing the 3,:

f(x) = 3x² - 48x + 192 - 160

f(x) = 3x² - 48x + 32

The denominators are not 4!!! The denominator is 11 everywhere

The graph of the inequality 2x + y > 4 in the coordinate plane is a shaded region above the line 2x + y = 4.

We have,

The given inequality is in the form of the equation of a straight line in two dimensions, but it also includes an inequality.

To graph this inequality on the coordinate plane, we first need to graph the equation of line 2x + y = 4.

We can do this by finding the x and y intercepts of the line.

To find the x-intercept, we set y = 0 and solve for x:

2x + 0 = 4

2x = 4

x = 2

So the x-intercept is (2, 0).

To find the y-intercept, we set x = 0 and solve for y:

2(0) + y = 4

y = 4

So the y-intercept is (0, 4).

Therefore,

The graph of the inequality 2x + y > 4 in the coordinate plane is a shaded region above the line 2x + y = 4.

The probability of randomly selecting a gold medalist from the US is0.019

First, the probability of winning a gold medal is given by the quotient between the number of gold medals and the total number of medals.

The number of medals is:

gold = 48 + 90 + 107 + 114 + 397 = 756

There are 1,019 silver ones

There are 782 bronze ones

Then the total number is 756 + 1019 + 782 = 2,557

Then the probability for the gold medal is:

P = 756/2,557

And the probability that the gold medalist is from the US is given by the quotient between the number won by the US (48) and the total number of gold ones (756)

So we get.

Q = 48/756

The florist may make 10 centerpieces with each centerpiece holding 12 flowers, costing the customer $300, using 1.5 roses, 3 lilies, and 1.5 irises.

a) Let's denote the number of roses, lilies, and irises in each centerpiece by r, l, and i, respectively. Then we have the following system of linear equations:

12 = r + l + i (since each centerpiece contains 12 flowers)

r = 2(i + l) (since there are twice as many roses as the number of irises and lilies combined)

2.5r + 4l + 2i = 30 (since the cost of each centerpiece is $30 and we are given the prices of each type of flower)

b) We may organize the variable coefficients into a matrix and the constants into a vector to get the matrix equation. The matrix equation will have the form Ax = b, where A is the coefficients matrix, x is the variable vector, and b is the constant vector. Here are the facts:

[tex]\begin{pmatrix}1 & 1 & 1 \\2 & -2 & -2 \\2.5 & 4 & 2 \\\end{pmatrix}\begin{pmatrix}r \\l \\i \\\end{pmatrix}$=\begin{pmatrix}12 \\0 \\30 \\\end{pmatrix}$[/tex]

c) We must solve the matrix equation using the inverse of the coefficient matrix in order to determine how many flowers of each kind the florist may utilize to build the 10 centerpieces. When we multiply both sides of the equation by the coefficient matrix's inverse, we obtain:

[tex]\begin{pmatrix}1 & 1 & 1 \\2 & -2 & -2 \\2.5 & 4 & 2 \\\end{pmatrix}^{-1} \begin{pmatrix}1 & 1 & 1 \\2 & -2 & -2 \\2.5 & 4 & 2 \\\end{pmatrix} \begin{pmatrix}r \\l \\i \\\end{pmatrix}=\begin{pmatrix}1 & 1 & 1 \\2 & -2 & -2 \\2.5 & 4 & 2 \\\end{pmatrix}^{-1}\begin{pmatrix}12 \\0 \\30 \\\end{pmatrix}[/tex]

Simplifying, we get:

[tex]\begin{pmatrix}r \\ l \\ i\\ \end{pmatrix}=\begin{pmatrix}1.5 \\3 \\1.5\\ \end{pmatrix}[/tex]

The ratio of the area of triangle BDC to the area of triangle ADC is

(√3 -1) : 2.

Angle ABC  = 60°

Angle DBC  = 45°

So, the measure of <ABD is

Angle ABD = ABC  - DBC

                   = 60 - 45

                   = 15°

Now, the area of triangle CDB is

= (1/2) * S * BD * sin 45

and, the area of triangle ADB

= (1/2) * S * BD * sin 15

So, the area of triangle ADB to the area of triangle CDB  =

= (1/2) * S * BD * sin 15 / (1/2 * S * BD  * sin 45  

= sin 15 / sin 45

Since, sin 15 = sin (45 -30)

                    =  sin45 cos30 - sin 30 cos 45

                    = √2/2 √3/2 -  (1/2)(√2/2)

                    = [√6 -√2] /4

                    = √2/2

So, sin 15  / sin 45 = [√6  -√2 ] / 4*2 /√2

                              =  [ √6  - √2 ]  / [ 2√2 ]

                               = √6 / [ 2√2 ]  - √2 / [ 2√2]

                               = √3 / 2  -  1/ 2

In an ANOVA summary report, SS stands for Sum of Squares.

It is a key term used in the analysis of variance (ANOVA) technique, which helps in assessing the differences among group means in a sample. The Sum of Squares is calculated to partition the total variability in the dataset into components attributable to different sources.

The ANOVA summary report typically includes the following elements: Source of variation (between groups, within groups, and total), Degrees of Freedom (DF), Sum of Squares (SS), Mean Squares (MS), F-ratio, and the p-value. The Sum of Squares is essential in determining the Mean Squares, which is calculated by dividing the SS by the corresponding degrees of freedom. The F-ratio is then derived by dividing the Mean Square Between Groups by the Mean Square Within Groups.

In conclusion, the term SS in an ANOVA summary report refers to the Sum of Squares, which represents the total variability in the dataset divided into components based on different sources. This concept is vital for conducting the analysis of variance and assessing the statistical significance of differences among group means.

     θ = 30.8° (3 s.f.)

(b)  radius = 3.00 cm (3 s.f.)

Step-by-step explanation:

The given triangle is made up of two right triangles.

In the right triangle on the right side, the side labelled "x" is opposite angle 40° and the side labelled 8 cm is adjacent to angle 40°. Therefore, to find the length of side x, use the tangent trigonometric ratio.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]

Therefore, the values are:

Substitute the values into the equation and solve for x:

[tex]\implies \tan 40^{\circ}=\dfrac{x}{8}[/tex]

[tex]\implies 8 \cdot \tan 40^{\circ}=8 \cdot\dfrac{x}{8}[/tex]

[tex]\implies 8 \tan 40^{\circ}=x[/tex]

[tex]\implies x=8 \tan 40^{\circ}[/tex]

[tex]\implies x=6.71279704...[/tex]

[tex]\implies x=6.71\; \rm cm\;(3\;s.f.)[/tex]

Therefore, the length of side x is 6.71 cm (3 s.f.).

In the right triangle on the left side, the side labelled "x" is adjacent angle θ and the side labelled 4 cm is opposite to angle θ. Therefore, to find the size of angle θ, use the tangent trigonometric ratio.

Therefore, the values are:

Substitute the values into the equation and solve for x:

[tex]\implies \tan \theta=\dfrac{4}{x}[/tex]

[tex]\implies \tan \theta=\dfrac{4}{8 \tan 40^{\circ}}[/tex]

[tex]\implies \tan \theta=\dfrac{1}{2 \tan 40^{\circ}}[/tex]

[tex]\implies \theta=\tan^{-1}\left(\dfrac{1}{2 \tan 40^{\circ}}\right)[/tex]

[tex]\implies \theta=30.7897330...^{\circ}}[/tex]

The correct statements in the given options are, x = 51,  y = 34,  and m ∠1 = 44⁰

options, B,D,E

The value of x and y can be determined by applying the following equation.

3y - 18 = 84 (vertical opposite angles are equal)

3y = 102

y = 102/3

y = 34

The value of x is calculated as follows;

∠1 + 3y - 18 + ²/₃(x + 27) = 180 (sum of angles on a straight line)

∠1 + 3(34) - 18 + ²/₃(x + 27) = 180

∠1  + ²/₃(x + 27)  = 96

∠1  = 96 -  ²/₃(x + 27)  -------(1)

3x - 25  = 3y - 18 + ∠1 ---- (2)

3x - 25 = 3y - 18 + 96 -  ²/₃(x + 27)

3x + ²/₃(x + 27) = 3y + 103

3x + ²/₃(x + 27) = 3(34) + 103

3x + ²/₃(x + 27) = 205

9x + 2x + 54 = 615

11x = 561

x = 561/11

x = 51

The value of angle 2 is calculated as;

∠2 = 180 - (3x - 25)

∠2 = 180 - 3x + 25

∠2 = 180 - 3(51) + 25

∠2 = 52⁰

The value of angle 1 is calculated as follows;

∠1  = 96 -  ²/₃(x + 27)
