The dimensions of the rectangular garden to maximize the area is length = width = 75 meters.

Let l be the length and w be the width of the rectangular garden.

We need to find the dimensions of the rectangular garden of greatest area that can be fenced off (all four sides) with 300 meters of fencing.

The perimeter of the  rectangular garden = 300 meters

We know that the perimeter of the rectangle =2(length + width)

300 = 2(l + w)

l + w = 150               .......(1)

Now, the maximum area of a  rectangular garden is when Length  = width

So, for equation 1

l + l = 150

l = 75 meters

So, w = 75 meters

And the area of the rectangular garden = length * width

                                                               = 75 * 75

                                                               = 5625 m²

So the maximum area of the  rectangular garden is 5625 m²

Therefore, the dimensions of the garden to maximize the area is length = width = 75 meters and maximum area is  5625 m²

The equation in the slope-intercept form will be:

\(y=2x+10\)

Step-by-step explanation:

Given the points

Finding the slope between two points

\(\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-4,\:2\right)\)

\(\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{2-4}{-4-\left(-3\right)}\)

\(m=2\)

As the point-slope form  of the line equation is

\(y-y_1=m\left(x-x_1\right)\)

putting the values m=2 and the point (-3, 4)

\(y-4=2\left(x-\left(-3\right)\right)\)

\(y-4=2\left(x+3\right)\)

Writing the equation in slope-intercept form

\(y=mx+b\)

where m is the slope, and b is the y-intercept

so the equation becomes

\(y-4=2\left(x+3\right)\)

add 4 to both sides

\(y-4+4=2\left(x+3\right)+4\)

\(y=2x+10\)

Therefore, the equation in the slope-intercept form will be:

\(y=2x+10\)

Answer:

The area of the rectangle is increasing at a rate of 54 cm2/s.

Step-by-step explanation:

The critical value that corresponds to a confidence interval of 95.9% is 1.99.

The distribution of the sample mean will be roughly normally distributed, according to the Central Limit Theorem, if we have an unknown population with a mean and standard deviation and adequately small random samples (n < 30) are chosen from the population with replacement.

Then, the mean of the sample means is given by,

μ(x) = μ

And the standard deviation of the sample means is given by,

σ = σ / \(\sqrt{n}\)

In this case the sample selected is of size, n = 7.

As the sample size n = 7 < 30, the sampling distribution of sample mean will be approximately normal.

So, a z-interval will be used to estimate the population mean.

The confidence level is, 95.9%.

The value of α is:

∝ = 1 - confidence level

∝ = 1 - 0.959

∝ = 0.041

The critical value is:

\(z_{\frac{∝ }{2} }\) =  \(z_{\frac{0.041}{2} }\)

\(z_{\frac{∝ }{2} }\) = \(z_{0.0205}\)

\(z_{\frac{∝ }{2} }\) = -1.99

\(z_{1-∝/2}\) = 1.99

Use a z-table.

Therefore,

The critical value that corresponds to a confidence interval of 95.9% is 1.99.

To determine how the surface area of a rectangular prism changes when all dimensions are quadrupled, we need to compare the original surface area to the new surface area.

The original surface area of the rectangular prism is given by:

SA_original = 2lw + 2lh + 2wh

where l, w, and h represent the length, width, and height of the prism, respectively.

In this case, the dimensions of the original box are:

Length (l) = 3 ft

Width (w) = 6 ft

Height (h) = 5 ft

Substituting these values into the formula, we have:

SA_original = 2(3)(6) + 2(3)(5) + 2(6)(5)

            = 36 + 30 + 60

            = 126 square feet

Now, if we quadruple all the dimensions of the box, the new dimensions would be:

Length (l_new) = 4(3) = 12 ft

Width (w_new) = 4(6) = 24 ft

Height (h_new) = 4(5) = 20 ft

The new surface area of the enlarged box is given by:

SA_new = 2(l_new)(w_new) + 2(l_new)(h_new) + 2(w_new)(h_new)

       = 2(12)(24) + 2(12)(20) + 2(24)(20)

       = 576 + 480 + 960

       = 2016 square feet

Comparing the original surface area (SA_original = 126 sq ft) to the new surface area (SA_new = 2016 sq ft), we can see that SA_new is 16 times greater than SA_original.

Therefore, the correct answer is:

1. The new surface area would be 16 times the original surface area.

The final answer is (a+b)⁴ = a⁴ + 4a³b + 6a²b² + 4ab³ + b⁴.

Pascal's Triangle is a useful tool in expanding binomial expressions, which is a fundamental concept in algebra. For example, let's expand (a+b)⁴ using Pascal's Triangle.

Step 1: Write out Pascal's Triangle to the 4th row, as follows:

1

1 1

1 2 1

1 3 3 1

1 4 6 4 1

Step 2: Write out the coefficients in the binomial expression (a+b)⁴:

(a+b)⁴ = 1a⁴ + 4a³b + 6a²b² + 4ab³ + 1b⁴

Step 3: Substitute the coefficients from Pascal's Triangle into the binomial expression:

(a+b)⁴ =  1a⁴ + 4a³b + 6a²b² + 4ab³ + 1b⁴

=  1a⁴ + 4a³b + 6a²b² + 4ab³ + 1b⁴

= 1(a⁴) + 4(a³b) + 6(a²b²) + 4(ab³) + 1(b⁴)

= (1)(a⁴) + (4)(a³)(b) + (6)(a²)(b²) + (4)(a)(b³) + (1)(b⁴)

Step 4: Simplify the expression to get the final answer:

(a+b)⁴ = a⁴ + 4a³b + 6a²b² + 4ab³ + b⁴

Notice how the coefficients of each term in the expanded expression (1, 4, 6, 4, 1) correspond to the fourth row of Pascal's Triangle. Pascal's Triangle provides a quick and easy way to determine the coefficients of a binomial expansion for a given power of the binomial expression.

Answer:

The solutions to the equation 5x^2-2x-1=4x to the nearest tenth are x ≈ 1.3 or x ≈ -0.4.

Step-by-step explanation:

To solve the equation 5x^2-2x-1=4x to the nearest tenth, we can start by moving all the terms to one side of the equation.

5x^2-2x-1=4x

5x^2-6x-1=0

Next, we can use the quadratic formula to solve for x:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 5, b = -6, and c = -1.

Plugging these values into the formula gives:

x = (-(-6) ± sqrt((-6)^2 - 4(5)(-1))) / 2(5)

x = (6 ± sqrt(56)) / 10
