Answer:

x< -3 and 0 < x < 4

Step-by-step explanation:

x^3 – x² <12x​

Subtract 12x from each side

x^3 -x^2 - 12x< 0

Factor

x( x^2 -x-12) <0

Factor

x( x-4) ( x+3) < 0

Using the zero product property

x=0   x=4  x=-3

We have to check the signs regions

x < -3

-( -) (-) < 0   True

-3 to 0

0 to 4

+( -) (+) < 0   True

x>4

+( +) (+) < 0   False

The correct option is (E)  "The amount of fertilizer applied to each plot of land." In this  linear regression equation, the family needs to select an explanatory variable that they can control and that can affect the amount of grain harvested per acre of land.

Out of the given options, "amount of fertilizer applied to each plot of land" is the most appropriate explanatory variable that the family could use to create a linear regression equation. By controlling the amount of fertilizer used, the family can investigate the relationship between fertilizer and the amount of grain harvested per acre of land. They can then use this relationship to predict the amount of grain they can harvest if they use a certain amount of fertilizer in the future. so, the correct option is (E).

Answer:

1) x  =  [ - (12/1000)*  e∧ ( - 15/1000)*t  + 12/1000 ] /e∧ - (15/1000)*t

2) x =  - 0,012 * ( e ∧ 0.18 + 0,012 ) / e∧-0,18

Step-by-step explanation:

1.-Quantity of salt in the tank after t minutes

The rate  of change of the quantity of salt in the tank is:

dx(t) /dt   =  original quantity (0) + input quantity - output quantity  (1)

quantity = concentration* rate   Then

input quantity   =  0.04 Kg/lt * 5 Lt/min + 0.06 Kg/lt * 10Lt/min  =  0.2 Kg/min

+ 0.6  Kg/min  =  0,8 Kg/lt

output quantity =  Output concentration * rate of draining

rate of draining = 15 Lt/min

The input quantity and the output quantity occur at the same rate therefore the volume in the tank is constant  1000Lt.

output quantity = (x/1000 )*15

Plugging these values in equation (1) we get.

dx/dt  =  0,8  -  ( x/1000)* 15

The last one is a differential first-order equation like

x´ +  P(t)*x = q(t)

and the solution is:

x*μ   =  ∫ q(t)*μ*dt  + C

where    μ  is the integration factor   e ∧ ∫p(t)*dt

let´s call  b = -15/1000

μ = e ∧ ∫p(t)*dt  =  e∧∫ b*dt  =  e∧ b*t = e∧ ( -15/1000)*t

μ  =  e∧ - (15/1000)*t

Then  x*μ    =   x *  e∧ - (15/1000)*t

∫ q(t)*μ*dt  = ∫  0.8 * e∧ - (15/1000)*t*dt  =  0.8 * ∫ e∧bt * dt  

 ∫ q(t)*μ*dt  = 0.8 * ( 1/b ) e∧bt  = - 0,8 *( 15/1000) * e∧ ( - 15/1000)*t

∫ q(t)*μ*dt  = - (12/1000)*  e∧ ( - 15/1000)*t

x *  e∧ - (15/1000)*t  =   - (12/1000)*  e∧ ( - 15/1000)*t + C

Initial condition  t = 0  x = 0

0  =  - (12 / 1000 )* e⁰ = C

C = 12/1000

x *  e∧ - (15/1000)*t  =   - (12/1000)*  e∧ ( - 15/1000)*t  + 12/1000

x  =  [ - (12/1000)*  e∧ ( - 15/1000)*t  + 12/1000 ] /e∧ - (15/1000)*t

When t = 60 min

x =   [ - (12/1000)*  e∧ ( - 15/1000)*12 + 12/1000 ] / e∧ - (15/1000) * 12

x =  - 0,012 * ( e ∧ 0.18 + 0,012 ) / e∧-0,18

Step-by-step explanation:

We know the the total of angles for a triangle is 180 degrees.

So in this case we'd want to set up adding all of our angles and setting them equal to 180

17 + 126 + b = 180

then solve for b

143 + b = 180

b = 37 degrees

ANSWER and EXPLANATION

(a) For the path of the two comets, the sun is located at the origin (0, 0).

The equation that models the path of comet E is:

This is the equation of an ellipse, in other words, the path of comet E is elliptic.

The standard equation of an ellipse is:

where (h, k) = center

(h, k ± a) = vertex

Comparing the equation for comet E to the general equation, we see that center of the ellipse is (0, -16) and the vertices of comet E are:

The equation that models the path of comet H is:

This is the equation of a hyperbola, hence, the path of comet H is hyperbolic.

The standard equation of a hyperbola is:

where (h, k) = center

(h, k ± a) = vertex

Comparing the equation of comet H to the standard equation, we see that the center of comet E is (0, 13), and the vertices of comet H are:

(b) Checking the vertices of both comets, we see that the vertices of comet H are closer to the origin than for comet E. This implies that comet H travels closer to the sun.

(c) We are given that the sun is at the origin of the coordinate system being considered.

We see that this represents the focus of the elliptic path that comet E takes and the hyperbolic path that comet H takes.

This can be shown by calculating the focus for comet E.

For comet E (ellipse), the focus is:

where c is:

For comet E, we will use the focus closer to the sun.

We have that:

and the focus is:

Hence, we see that the focus of the comets is at the origin i.e. the sun.

Step-by-step explanation:

supplementary angles are angles that combine to form a straight line (and we know that a straight line = 180 degrees)

you can think of an angle as needing another angle to "supplement" it into being a full line.

So, we know that one angle = 37°

And that: one angle + supplementary angle = 180 degrees

                 37° + x  = 180°

                - 37           -37

                     x    = 143

So, the measure of this angle's supplement is 143°

The value of x in the equation 4 x plus 8 y equals 40 is 8.4

The equation is given as:

4 x plus 8 y equals 40

Rewrite the equation as:

4x + 8y = 40

The value of y is 0.8.

So, we have:

4x + 8 * 0.8 = 40

Divide through by 4

x + 2 * 0.8 = 10

Evaluate the product

x + 1.6 = 10

Subtract 1.6 from both sides

x = 8.4

Hence, the value of x in the equation 4 x plus 8 y equals 40 is 8.4

\(-3x+10-10\leq5-10\\\\\Rightarrow\ -3x\leq-5\)

Multiply negative sign on both sides ,we get

\(3x\geq5\)

Divide both sides by 3, we get

Since we have a right angle triangle ; The angle L can be obtained thus ;

L = 180 - (90+67)

L = 23

Using Trigonometry:

Sin23° = opposite/ hypotenuse

Opposite= 6.7

hypotenuse= x

Sin23° = 6.7/x

x = 6.7/sin(23°)

x = 17.14

To find the maximum revenue, we can substitute \(p = 123\) into the revenue equation: the maximum revenue is $\(75,615.\)

To find the price that will maximize revenue, we need to find the value of p that corresponds to the maximum of the quadratic function \(R(p) = -5p^2 + 1230p.\)

One way to do this is to use calculus. We can take the derivative of R(p) with respect to p and set it equal to zero to find the critical point(s):

\(R'(p) = -10p + 1230\)

\(-10p + 1230 = 0\)

\(p = 123\)

So, the price that will maximize revenue is $\(123.\)

To confirm that this is a maximum, we can take the second derivative of R(p) and evaluate it at \(p = 123:\)

\(R''(p) = -10\)

Since  \(R''(123) = -10 < 0\)  , we know that  \(p = 123\) corresponds to a maximum.

To find the maximum revenue, we can substitute p = 123 into the revenue equation:

\(R(123) = -5(123)^2 + 1230(123) = $75,615\)

Therefore,  the maximum revenue is $\(75,615.\)
