x  =  0,5 ft

y =  2 ft   and

V = 2 ft³

Step-by-step explanation:  See annex

c) V = y*y*x

d-1) y = 3 - 2x

d-2) V = (3-2x)* ( 3-2x)* x   ⇒ V = (3-2x)²*x    

V(x) =( 9 + 4x² - 12x )*x    ⇒   V(x) = 9x + 4x³ - 12x²

Taking derivatives

V¨(x) = 9 + 12x² - 24x

V¨(x) = 0              ⇒   12x² -24x +9 = 0     ⇒  4x² - 8x + 3 = 0

Solving for x (second degree equation)

x =[ -b ± √b²- 4ac ] / 2a

we get    x₁  =  1,5       and    x₂ =  0,5

We look at y = 3 - 2x    and see that the value x₂ is the only valid root

then

x  =  0,5 ft

y =    2 ft   and

V = 0,5*2*2

V = 2 ft³

Answer:

The measure of the sides is 20 cm.

Step-by-step explanation:

Opposite side of a parallelogram:

Opposite sides of a parallelogram are congruent, that is, they have the same measure.

Measures (2x+10) cm and (x+15) cm:

This means that:

[tex]2x + 10 = x + 15[/tex]

[tex]2x - x = 15 - 10[/tex]

[tex]x = 5[/tex]

2x + 10 = 2*5 + 10 = 10 + 10 = 20

The measure of the sides is 20 cm.

Answer:

Use the distributive property to get 4c-12=8

Divide both sides by 4 to get c-3=2

Direct and Inverse proportionality was discussed with examples.

Direct proportionality: Direct proportionality means the change of a similar kind.

For example, as pressure increases, density also increases, which means both the parameters (pressure and density) are experiencing a similar kind of change i.e. increment in their magnitude.

The constant of proportionality is the ratio that relates two given values.

For example, Density ∝ pressure

Density = k(Pressure)

Here k  is the constant of proportionality

Inverse proportionality: Inverse proportionality means the change of the opposite kind.

For example, as the population increases, natural resources decrease, which means parameters(population and natural resources) are experiencing the opposite kind of change i.e one is increasing other is decreasing.

Thus, Direct and Inverse proportionality were discussed with examples.

B. The second graph

Step-by-step explanation:

got the answer from edge

Answer:

31x=217     x=7

Step-by-step explanation:

begin with what you know. You know that you will have 31 days to complete the goal and that the goal is 217 miles. This gives you your y (217) and your m (31). Then set up into y=mx+b form. This gives 31x=217. Then to solve divide 217 by 31. This gives the needed the needed answer of 7 miles per day  

Answer:

The animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

[tex]Cost = 51.275[/tex]

Step-by-step explanation:

The given parameters can be summarized as:

[tex]\begin{array}{cccc}{} & {x} & {y} & {Total} & {Protein} & {70} & {21} & {168} &{Fats}& {9} & {7} & {27} & {Minerals} & {7} & {1} & {14}& {Cost} & {21} & {7} & {} \ \end{array}[/tex]

Where: x = Soybeans and y = Oats.

So, the system of equations are:

[tex]70x + 21y = 168[/tex]

[tex]9x +7y = 27[/tex]

[tex]7x + y = 14[/tex]

[tex]Cost = 21x + 7y[/tex]

The best way to solve this, is using graph

Plot the following equations on a graph, and get the points of intersection:

[tex]70x + 21y = 168[/tex]

[tex]9x +7y = 27[/tex]

[tex]7x + y = 14[/tex]

From the attached graph, we have:

[tex](x_1,y_1) = (1.636,2.545)[/tex]

[tex](x_2,y_2) = (1.775,1.575)[/tex]

[tex](x_3,y_3) = (2.023,1.256)[/tex]

Substitute each of the values of x's and y's in the cost function to get the minimum cost:

[tex]Cost = 21x + 7y[/tex]

[tex](x_1,y_1) = (1.636,2.545)[/tex]

[tex]Cost = 21 * 1.636 + 7 * 2.545[/tex]

[tex]Cost = 52.171[/tex]

[tex](x_2,y_2) = (1.775,1.575)[/tex]

[tex]Cost = 21 * 1.775 + 7 * 1.575[/tex]

[tex]Cost = 48.3[/tex]

[tex](x_3,y_3) = (2.023,1.256)[/tex]

[tex]Cost = 21 * 2.023 + 7 * 1.256[/tex]

[tex]Cost = 51.275[/tex]

The values of x and y that gives the minimum cost is:

[tex](x_2,y_2) = (1.775,1.575)[/tex]

and the minimum cost is:

[tex]Cost = 48.3[/tex]

Hence, the animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

Answer:

6:3

Step-by-step explanation:

Answer and Step-by-step explanation:

3 of the options are not to be chosen, and 3 are wanted.

That means that anything above 3 (so, 4, 5, or 6) are the numbers that are wanted, while the numbers 1, 2, and 3 are not wanted.

We have 6 total options.

The ration would be:

3:6, or 3 to 6. This reduces down to 1:2, or 1 to 2.

That means that there is a 50% chance of getting 4, 5, or 6.

Answer:

this is correct on plato/edmentum

Step-by-step explanation:

For an equation to be viable, the result of the equation must be positive (i.e. greater than 1).

The 2 templates, the farmer created have two solutions, but only one of the solutions are viable.

For the first template, we have:

[tex]x \to[/tex] length of the shorter leg of the triangle

[tex]z \to[/tex] length of the longer leg of the triangle

From the question, we have:

[tex]z = 4 + 6x[/tex]

The area (y) of the first template is:

[tex]y = \frac{1}{2}xz[/tex] --- area of a triangle

So, we have:

[tex]y = \frac{1}{2}x(4 + 6x)[/tex]

Open bracket

[tex]y = 2x + 3x^2[/tex]

For the second template, we have:

[tex]Width = 5 + x[/tex]

[tex]Length = 3[/tex]

So, the area (y) of the second template is:

[tex]y = Length \times Width[/tex] --- area of a rectangle

This gives:

[tex]y = 3 \times (5 + x)[/tex]

[tex]y = 3(5 + x)[/tex]

[tex]y = 15 + 3x[/tex]

So, the expression for both areas are:

[tex]y = 2x + 3x^2[/tex] --- template 1

[tex]y = 15 + 3x[/tex] --- template 2

Both areas must be equal. This is represented as:

[tex]2x + 3x^2 = 15 + 3x[/tex]

Collect like terms

[tex]3x^2 +2x - 3x - 15 = 0[/tex]

[tex]3x^2 - x - 15 = 0[/tex]

Solve for x using quadratic formula, we have:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where:

[tex]a = 3; b =-1; c=-15[/tex]

So, we have:

[tex]x = \frac{-(-1) \± \sqrt{(-1)^2 - 4\times 3 \times -15}}{2 \times 3}[/tex]

[tex]x = \frac{1 \± \sqrt{181}}{6}[/tex]

[tex]x = \frac{1 \± 13.5}{6}[/tex]

Split

[tex]x = \frac{1 + 13.5}{6} \ or \ x = \frac{1 + 13.5}{6}[/tex]

[tex]x = \frac{-12.5}{6} \ or \ x = \frac{14.5}{6}[/tex]

[tex]x = -2.08 \ or \ x = 2.42[/tex]

We can see that x has 2 solutions, but only 1 of the solutions is viable because the other is negative.

Hence, option (a) is correct

Answer:

There is a 16% chance of the spinner dropping on a blue section on the first spin and then a blue section of the second spin.

Step-by-step explanation:

Given that I spin a spinner that is equally divided into 5 parts, and then I spin it again, knowing that 1 part is pink, 2 parts are blue, and 2 parts are black, to determine what is the probability of the spinner dropping on a blue section on the first spin and then a blue section of the second spin the following calculation must be performed:

Blue parts: 2

Total Parts: 5

2/5 = 0.4 = 40%

0.40 x 0.40 = 0.16

Thus, there is a 16% chance of the spinner dropping on a blue section on the first spin and then a blue section of the second spin.

Answer:

x = 612

Step-by-step explanation:

x = 2(y + z)        Divide by 2 to isolate y + z

x/2 = y + z         Set up the sum of three numbers        

x + y + z = 918   Substitute x / 2 for y + z

x + x/2 = 918     Combine like terms

3/2 x = 918        Multiply both sides by 2/3

2/3 * 3x/2 = 2/3 * 918

x = 612
