Por lo tanto, la parcela mide 18 metros de largo y 12 metros de ancho.

Llamemos "largo" (L) a una de las dimensiones de la parcela y "ancho" (A) a la otra dimensión.

Según la información dada, sabemos que la suma del largo y el ancho es de 30 metros:

L + A = 30 ---(1)

También se nos dice que la diferencia entre el largo y el ancho es de 6 metros:

L - A = 6 ---(2)

Podemos resolver este sistema de ecuaciones utilizando el método de sustitución o de eliminación. En este caso, resolveremos utilizando el método de sustitución.

De la ecuación (2), podemos despejar L en términos de A:

L = A + 6

Sustituyendo este valor de L en la ecuación (1), obtenemos:

(A + 6) + A = 30

2A + 6 = 30

Restamos 6 de ambos lados de la ecuación:

2A = 30 - 6

2A = 24

Dividimos ambos lados de la ecuación por 2:

A = 12

Ahora que conocemos el valor de A, podemos encontrar el valor de L sustituyendo en la ecuación (2):

L = A + 6

L = 12 + 6

L = 18

The statement "The cup of flour has a mass of exactly 121.8 grams" is not true.

Since the baking scale measures mass to the tenth of a gram, it means it can measure values such as 121.7 grams, 121.8 grams, and 121.9 grams. However, it does not have the capability to measure beyond the tenths place, so it cannot determine whether the exact mass of the cup of flour is exactly 121.8 grams.

Answer:

Step-by-step explanation:

To find the diameter of the cylinder, we can use the formula for the volume of a cylinder:

Volume = π * radius^2 * height

Given:

Volume = 20π cm^3

Height = 5 cm

We can rearrange the formula to solve for the radius:

radius^2 = Volume / (π * height)

radius^2 = (20π) / (π * 5)

radius^2 = 4

radius = 2

Now, we can find the diameter by multiplying the radius by 2:

diameter = 2 * radius

diameter = 2 * 2

diameter = 4

Therefore, the diameter of the cylinder is 4 cm.

Answer:

To calculate Mr. Chi's total tax bill, we need to find the amount of sales tax charged by each entity and add them together.

The state sales tax on the sale of a house is 3.2%, which means Mr. Chi will owe 0.032 x $289,300 = $9,267.20 in state sales tax.

The county sales tax on the sale of a house is 2.6%, which means Mr. Chi will owe 0.026 x $289,300 = $7,520.80 in county sales tax.

The city sales tax on the sale of a house is 1.8%, which means Mr. Chi will owe 0.018 x $289,300 = $5,207.40 in city sales tax.

Therefore, Mr. Chi's total tax bill will be $9,267.20 + $7,520.80 + $5,207.40 = $21,995.40.

Answer:

Step-by-step explanation:

Willis’s mistake is that he used the differences of 6, 10 and 14 instead of the differences of 7, 17 and 31. For a linear function, the y values should have a constant rate of change and not the differences.

The minimum y-value of g(x) is -3 and g(x) has the smallest possible y-value.

The function  f(x) = 32 - 3 is a constant function, as there is no variable term involving x. It simplifies to f(x) = 29.

Regardless of the value of x, the function f(x) will always have a y-value of 29.

Therefore, option A is incorrect because there is no minimum y-value for f(x); it is a constant.

g(x) = 7x² - 3 is a quadratic function in the form of ax² + bx + c, where a = 7, b = 0, and c = -3.

The coefficient a (7) is positive, indicating that the parabola opens upward.

Since there is no linear term (bx), the vertex of the parabola is located at the point (0, -3), which corresponds to the minimum y-value of the function.

To summarize:

√3 - 6x: Domain is all real numbers (-∞, +∞).

√13 - (13 - 2x): Domain is all real numbers (-∞, +∞).

1/√x - 2: Domain is all real numbers except x = 0, represented as (-∞, 0) U (0, +∞).

Step-by-step explanation:

To find the domain of each expression, we need to identify any restrictions or limitations on the variables that would result in undefined values.

√3 - 6x:

Since square roots are defined for non-negative numbers, the expression is defined as long as the value inside the square root (√3) is non-negative. The square root of 3 is a positive value, so there are no restrictions on the domain of this expression. Therefore, the domain is all real numbers (-∞, +∞).

√13 - (13 - 2x):

Similar to the previous expression, the square root (√13) is defined for non-negative values. However, we also need to consider the expression (13 - 2x) inside the parentheses. This expression does not have any limitations since it is defined for all real numbers. Therefore, the domain of this expression is all real numbers (-∞, +∞).

1/√x - 2:

For this expression, we need to consider both the square root (√x) and the denominator (1/√x). The square root (√x) is defined for non-negative values of x. However, the denominator 1/√x will become undefined if the value of x is zero because division by zero is undefined. Therefore, we need to exclude x = 0 from the domain. For all other non-zero values of x, the expression is defined. Therefore, the domain of this expression is all real numbers except x = 0, represented as (-∞, 0) U (0, +∞).

Answer:

Table B was created using the equation y = 4x-1.

Explanation:

The equation y = 4x-1 means that for any given value of x, the corresponding value of y can be found by multiplying x by 4 and then subtracting 1.

Table B shows input values of x and output values of y that are consistent with this equation. For example, when x = 3, y = 11 (4 * 3 - 1), and when x = 4, y = 15 (4 * 4 - 1), and so on.

Therefore, we can conclude that Table B was created using the equation y = 4x-1.

Step-by-step explanation:

To find the radius of the cylinder, we can use the formula for the volume of a cylinder:

Volume = π * radius^2 * height

Given:

Volume = 627.8 cm^3

Height = 19.5 cm

π (pi) = 3.14

Substituting the given values into the formula:

627.8 = 3.14 * radius^2 * 19.5

Simplifying the equation:

627.8 = 60.93 * radius^2

To solve for the radius, we can divide both sides of the equation by 60.93:

radius^2 = 627.8 / 60.93

radius^2 = 10.29

Taking the square root of both sides:

radius ≈ √10.29

Rounding to the nearest tenth:

radius ≈ 3.2

Therefore, the approximate radius of the cylinder is 3.2 cm.

Answer:

3.2

Step-by-step explanation:

The volume of a cylinder is:

Vol = pi•r^2•h

Fill in what is given.

627.8 = pi•r^2•19.5

use 3.14 for pi.

627.8 = 3.14•r^2•19.5

simplify.

627.8 = 61.23r^2

divide by 61.23

10.253 = r^2

sqrt both sides

sqrt10.253 = r

3.2 = r

Step-by-step explanation:

if you look at the pattern you will see that

The exact value of cos(θ/2) is:

[tex]cos(\frac{\theta }{2}) = \right-\sqrt{\frac{1}{122} }[/tex]

To find the exact value of cos(θ/2), we can use the half-angle formula for cosine:

[tex]cos(\frac{\theta }{2}) = \right\pm\sqrt{\frac{1+cos\theta}{2} }[/tex]

First, let's find the value of cos(θ) using the given information about θ:

Given:

tan(θ) = 11/60

θ lies in the 3rd quadrant (π < θ < 3π/2)

In the 3rd quadrant, both sin(θ) and cos(θ) are negative.

tan(θ) = opposite/adjacent

Also, in the 3rd quadrant, both opposite and adjacent are negative.

Thus,

opposite = -11

adjacent = -60

hypotenuse = √[(-60)² + (-11)²]   (Pythagoras theorem)

hypotenuse = 61

cos(θ) = adjacent/hypotenuse

cos(θ) = -60/61

Finally, we can substitute these values into the half-angle formula for cosine:

[tex]cos(\frac{\theta }{2}) = \right\pm\sqrt{\frac{1+(\frac{-60}{61})}{2} }[/tex]

[tex]cos(\frac{\theta }{2}) = \right\pm\sqrt{\frac{\frac{1}{61} }{2} }[/tex]

[tex]cos(\frac{\theta }{2}) = \right\pm\sqrt{\frac{1}{122} }[/tex]

Since the cos(θ/2) is negative. Therefore, the exact value of cos(θ/2) is:

[tex]cos(\frac{\theta }{2}) = \right-\sqrt{\frac{1}{122} }[/tex]

Reema should use 3 hooks, with a distance of 7 inches between each hook, and each hook will be positioned 5 3/8 inches from the left edge of the wood.

To determine the number of hooks Reema should use, we first need to calculate the available space on the wood for the hooks.

The total length of the wall is 4 feet, which is equivalent to 48 inches. Reema wants to center the coat rack, so she will have an equal amount of space on either side.

Therefore, each side will have (48 - 28 1/4) / 2 = 9 3/8 inches of space.

Next, we need to determine the distance between the hooks.

Reema wants about 7 or 8 inches of space between each hook.

Let's choose 7 inches for consistency.

Since there will be (n - 1) spaces between n hooks, the total space taken by the spaces will be 7 [tex]\times[/tex] (n - 1) inches.

Now, let's subtract the space taken by the spaces from the available space on the wood: 9 3/8 - 7 [tex]\times[/tex] (n - 1) = 9 3/8 - 7n + 7 inches.

Reema wants the first and last hooks to be no less than 1 3/4 inches from either end of the wood.

Therefore, we subtract twice this distance from the remaining space: 9 3/8 - 7n + 7 - 2 [tex]\times[/tex] (1 3/4) = 9 3/8 - 7n + 7 - 3 1/2 inches.

Now we have the expression 9 3/8 - 7n + 7 - 3 1/2 inches representing the remaining space.

We want this value to be greater than or equal to zero, as it should not be negative.

Simplifying the expression, we have 18 7/8 - 7n - 3 1/2 inches ≥ 0.

Now we can solve this inequality to find the range of values for n, the number of hooks.

We can then determine the distance between the hooks by dividing the remaining space by the number of spaces, and the distance of each hook from the left edge of the wood by adding the space taken by the spaces to the distance between the hooks.
