The length of the rectangle is 8 inches and the width is 8 inches and the maximum area of the rectangle is 64 square inches.

Let's assume that the length of the rectangle is x and the width is y.

We know that the perimeter of the rectangle is 32 inches.

Perimeter = 2(length + width)

So we have

2(x + y) = 32

x + y = 16

Now we want to find the maximum area of the rectangle.

The area of the rectangle is given by

Area = length × width = x y

We can use the perimeter equation to solve for y in terms of x

y = 16 - x

Now we can substitute y in terms of x into the equation for the area

Area = x(16 - x) = 16x - x^2

To find the maximum area, we need to find the value of x that maximizes this equation.

We can do this by taking the derivative of the equation with respect to x and setting it equal to zero

d/dx (16x - x^2) = 16 - 2x = 0

Solving for x, we get

x = 8 inches

Now we can substitute x = 8 back into the equation for y to find the corresponding value of y

y = 16 - x = 16 - 8 = 8 inches

So the length of the rectangle is 8 inches and the width is 8 inches as well.

Therefore, the maximum area of the rectangle is

Area = 8 × 8 = 64 square inches.

Answer

Edge length of the cube = 1.067 units

Explanation

The volume of a cube of edge length, L units, is given as

Volume = L³

For this question,

Volume = 1.216 cubic units

L = edge length = ?

Volume = L³

1.216 = L³

We can rewrite this

L³ = 1.216

Take the cube root of both sides

∛(L³) = ∛(1.216)

L = 1.067 units

The maximum height reached by each stone is 40.5 meters.

The height of each stone above the ocean is given by the function:

h = -2t² + 2t + 40

This is a quadratic function in standard form, with a = -2, b = 2, and c = 40.

The maximum height reached by the stone occurs at the vertex of the parabolic curve described by this function.

The t-coordinate of the vertex is given as:

t = -b / 2a

Substitute the values of a and b,

t = -2 / (2×(-2)) = 0.5

So the maximum height is reached 0.5 seconds after the stone is thrown.

To find the maximum height, substitute the value of t into the function:

h = -2(0.5)² + 2(0.5) + 40 = 40.5 meters

Therefore, the maximum height reached by each stone is 40.5 meters.

The simplification of the given expression of (5^-2 x 4^-4)^-2. so there is only one positive power for each base is 5^4 x 4^8.

Usually, simplification involves proceeding with the pending operations in the expression. Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form. Simplification usually involves making the expression simple and easy to use later.

The expression is given by \((5^{-2} 4^{-4})^{-2}\)

Now Apply the law of indices:

\((5^{-2} 4^{-4})^{-2}\) =  \((5^{-2 \times {-2}} 4^{-4 \times {-2}})^\)

Evaluate the product;

\((5^{-2} 4^{-4})^{-2}\) = \(5^4 4^8\)

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,

\(\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\)

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

Hunter is standing 26.8 meters away from the tree while the shadow of the tree is 30.85 meters long. Since the distance between the Hunter and the top of the tree is equal to the shadow of the hunter. Therefore, the distance between Hunter and the top of the tree will be,

Distance between Hunter and the top of the tree = 30.85m - 26.8 m = 4.05 meter

Now, using the tangent function we can write,

Height of Hunter/ Shadow of hunter = Height of tree / Shadow of tree

1.75 m / 4.05 m = Height of the tree / 30.85 m

Height of the tree = 13.33 meters

Answer:

The selling price of the diamond necklace at Shamin Jewelers after 10% discount is:

$442 * 0.9 = $397.80

The selling price of the same necklace at the competitor's store after 34% and 14% discount is:

$527 * 0.66 * 0.86 = $247.08

So, Shamin Jewelers needs to offer an additional discount to meet the competitor's price:

$397.80 - $247.08 = $150.72

To calculate the additional rate of discount, we divide the difference by the original selling price at Shamin Jewelers and multiply by 100:

($150.72 / $442) * 100 = 34.11%

Therefore, Shamin Jewelers must offer an additional 34.11% discount to meet the competitor's price.

The result of the equation 2(x − 4) − 9 = 3(2x + 1) + 4 by using the distributive property is x = -6

The equation is

2(x − 4) − 9 = 3(2x + 1) + 4

The distributive property states that multiplying the sum of two or more variables by a number will provide the same result as multiplying each variable individually by the number and then adding the products together.

The distributive property of the addition

A(B + C) = AB + AC

The distributive property of the subtraction

A(B - C) = AB - AC

The equation is

2(x − 4) − 9 = 3(2x + 1) + 4

Apply the distributive property

2x-8-9 = 6x+3+4

2x-17 = 6x+7

Rearrange the like terms and combine it

2x-6x = 7+17

-4x = 24

Answer:1.02 5.27 are correct

Step-by-step explanation:We can solve this quadratic equation in cos(θ) by using the substitution u = cos(θ):

3u^2 + 6u - 4 = 0

Now we can use the quadratic formula to solve for u:

u = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 3, b = 6, and c = -4. Substituting these values, we get:

u = (-6 ± sqrt(6^2 - 4(3)(-4))) / 2(3)

u = (-6 ± sqrt(84)) / 6

u = (-3 ± sqrt(21)) / 3

Therefore, either:

i.  The position vector of X is 2b - a.

ii.  The position vector of Y is (3b + c)/4.

iii.  The ratio XY : Y Z is \(|(2b - a) - ((3b + c)/4)|/|((3b + c)/4) - (a + c)/2|\). Simplifying this expression will give us the final ratio.

i. To find the position vector x of point X, we can use the concept of vector addition. Since AB : BX = 2 : 1, we can express AB as a vector from A to B, which is given by (b - a). To find BX, we can use the fact that BX is twice as long as AB, so BX = 2 * (b - a). Adding this to the vector AB will give us the position vector of X: x = a + 2 * (b - a) = 2b - a.

ii. Similar to the previous part, we can express BC as a vector from B to C, which is given by (c - b). Since BY : YC = 1 : 3, we can find BY by dividing the vector BC into four equal parts and taking one part, so BY = (1/4) * (c - b). Adding this to the vector BY will give us the position vector of Y: y = b + (1/4) * (c - b) = (3b + c)/4.

iii. Z is the midpoint of AC, so we can find Z by taking the average of the vectors a and c: z = (a + c)/2. The ratio XY : YZ can be calculated by finding the lengths of the vectors XY and YZ and taking their ratio. Since XY = |x - y| and YZ = |y - z|, we have XY : YZ = |x - y|/|y - z|. Plugging in the values of x, y, and z we found earlier, we get XY : YZ =\(|(2b - a) - ((3b + c)/4)|/|((3b + c)/4) - (a + c)/2|\).
