Step-by-step explanation:

The name of the Platonic solid that resembles a cuboid is the hexahedron, or more commonly known as a cube.

The correct answer is option C.

The name of the Platonic solid that resembles a cuboid is the hexahedron, also known as a cube. The hexahedron is one of the five Platonic solids, which are regular, convex polyhedra with identical faces, angles, and edge lengths. The hexahedron is characterized by its six square faces, twelve edges, and eight vertices.

The term "cuboid" is often used in general geometry to describe a rectangular prism with six rectangular faces. However, in the context of Platonic solids, the specific name for the solid resembling a cuboid is the hexahedron.

The hexahedron is a highly symmetrical three-dimensional shape. All of its faces are congruent squares, and each vertex is formed by three edges meeting at right angles. The hexahedron exhibits symmetry under several transformations, including rotations and reflections.

Its regularity and symmetry make the hexahedron an important geometric shape in mathematics and design. It has numerous applications in architecture, engineering, and computer graphics. The cube, as a special case of the hexahedron, is particularly well-known and widely used in everyday life, from dice and building blocks to cubic containers and architectural structures.

Therefore, the option which is the correct is C.

The domain of the function f(x) = -3x + 2 is (-∞, +∞), representing all real numbers, and the range is (-∞, 2], representing all real numbers less than or equal to 2.

The function f(x) = -3x + 2 is a linear function defined by a straight line. To determine the domain of this function, we need to identify the range of values for which the function is defined.

The domain of a linear function is typically all real numbers unless there are any restrictions. In this case, there is no explicit restriction mentioned, so we can assume that the function is defined for all real numbers.

Therefore, the domain of the function f(x) = -3x + 2 is (-∞, +∞), which represents all real numbers.

Now, let's analyze the range of the function. The range of a linear function can be determined by observing the slope of the line. In this case, the slope of the line is -3, which means that as x increases, the function values will decrease.

Since the slope is negative, the range of the function f(x) = -3x + 2 will be all real numbers less than or equal to the y-intercept, which is 2.

Therefore, the range of the function is (-∞, 2] since the function values cannot exceed 2.

Subtract to find how much money it went down by

The perimeter of parallelogram ABCD is 43.49 units.

We know that BC = 10, so we can use the Pythagorean theorem to find the length of AD:

AD^2 = BC^2 + x^2

AD^2 = 10^2 + x^2

AD^2 = 100 + x^2

AD = √(100 + x^2)

Perimeter = AB + BC + CD + AD

Perimeter = 9 + 10 + 9 + √(100 + x^2)

angle B has measure 63 degrees and we can  use the sine function to find x:

sin 63 = x / √(100 + x^2)

x / √(100 + x^2) = sin 63

x = sin 63 * √(100 + x^2)

x = 0.819 * √(100 + x^2)

x / 0.819 = √(100 + x^2)

x^2 / 0.6761 = 100 + x^2

x^2 / 0.6761 - x^2 = 100

x^2 * (1 / 0.6761 - 1) = 100

x^2 = 100 / (1 / 0.6761 - 1)

x = √(100 / (1 / 0.6761 - 1))

x = 5.48

We then substitute x back into the expression for the perimeter:

Perimeter = 9 + 10 + 9 +√(100 + x^2)

Perimeter = 9 + 10 + 9 + √(100 + 5.48^2)

Perimeter = 9 + 10 + 9 +√(100 + 30.0304)

Perimeter = 43.49

Answer:

25 gallons of the 70% and 75 gallons of the 30%

Step-by-step explanation:

First, make three baskets. One having x, the second having 100-x, and the third having 100. The reason you have 100-x is because you are adding two unknown numbers, and when you add them they equal 100. And if they add to be 100, 100-x=100-x. To continue, under each basket, write the number of the percent. So the first basket would have 70 under it, the second one would have 30 under it, and the third one would have 40 under it. Then multiply the number inside the basket by the number under. Then you would get 70x+3,000+30x=4,000. Next, 40x+3,000=4,000. Then 40x=1,000. x=25. That's the first basket. For the second, you do 100-25 because of the equation inside the second basket, which is 75. Hope this helps!

The correct answer is, by choosing a = -2 and b = 1, we satisfy both inequalities .a < b:

To make both inequalities true, we need to select values for a and b that satisfy the given conditions:

a < b: This inequality means that the value of a should be less than the value of b.

|b| < |a|: This inequality means that the absolute value of b should be less than the absolute value of a.

One possible solution that satisfies both conditions is:

a = -2

b = 1

With these values, we have:

-2 < 1 (a < b)

|-1| < |2| (|b| < |a|)

Therefore, by choosing a = -2 and b = 1, we satisfy both inequalities.a < b:

This inequality states that the value of a should be less than the value of b. In other words, a needs to be positioned to the left of b on the number line. To satisfy this condition, we can choose a to be any number that is less than b. In the example I provided, a = -2 and b = 1, we can see that -2 is indeed less than 1, fulfilling the requirement.

|b| < |a|:

This inequality involves the absolute values of a and b. The absolute value of a number is its distance from zero on the number line, always resulting in a non-negative value. The inequality states that the absolute value of b should be less than the absolute value of a. To satisfy this condition, we can choose b to be any number with a smaller absolute value than a. In the example I provided, |1| is less than |(-2)|, as 1 is closer to zero than -2, fulfilling the requirement.

By selecting a = -2 and b = 1, we satisfy both inequalities: a < b and |b| < |a|. The specific values of -2 and 1 were chosen as an example, but there are multiple other values that would also satisfy the given conditions. The important aspect is that a is indeed less than b, and the absolute value of b is smaller than the absolute value of a.

3. f(2)/f(1) = 1.149.

Let h be the height of the beanstalk in inches after t days. Then we can write: \(h(t) = 7 * (1.15)^t\) where 1.15 is the factor by which the height increases each day.

i. To compute f(1)/f(0), we need to substitute t = 1 and t = 0 into the function f and divide:

f(1)/f(0) = [7 * (1.15)^1] / [7 * (1.15)^0]

f(1)/f(0) = 1.15/1

f(1)/f(0) = 1.15

ii. To compute f(2)/f(1), we need to substitute t = 2 and t = 1 into the function f and divide:

f(2)/f(1) = [7 * (1.15)^2] / [7 * (1.15)^1]

Answer:

3 training sessions

Step-by-Step Explanation:

What we are going to have are two equations set equal to each other. Our variable is going to be the letter x. X represents the number of personal training sessions we would have to have at their current costs for the two equations to equal each other. Because we are only doing one month, the membership costs will stay constant.

For Silver Gym, membership is $40 and training sessions are 25$ per session. That "per session" tells you that this is where the variable goes. Your equation for a month at Silver Gym is 25x + 40.

Do the same for Fit Factor; $70 membership, $15 per session: 15x + 70.

Now let's set them equal to each other:

25x + 40 = 15x + 70

Next, we want to get variables on one side and constants on the other. I like to do variables on the left and constants on the right but, this is just personal preference -- we'll end up with the same answer regardless. To do this, we are going to subtract 15x from both sides, subtract 40 from both sides, and then simplify. So the above equation becomes:

25x - 15x + 40 - 40 = 15x - 15x + 70 - 40

Simplify by combining like terms. The 15x and - 15x cancel each other out, same with the 40 and - 40. Leaving us with:

10x = 30

Divide both sides to isolate your variable x and satisfy the division property of equality.

x = 30/10

x = 3

You would have to do 3 training sessions for the two gyms to be equal in cost.

Answer:

I would say the second one

Step-by-step explanation:

f(x) has a range of y<0, because it is reflected over the x axis

g(x) = -5/7(3/5)^-x is also reflected over the x axis, except also in the y axis. Regardless of the reflection in the y-axis, y still cannot be equal to or greater than 0. Therefore, I believe it is the second choice.

(The third and forth choice are the same, which rules them both out. The first on reflects it over the y-axis, meaning that x can be greater than 0.)

You invested $3000 at 3% annual interest rate, and the remaining amount of $4000 - $3000 = $1000 was invested at 4% annual interest rate.

Let's assume you invested an amount, x, at 3% annual interest rate. This means the amount invested at 4% annual interest rate would be $4000 - x.

To calculate the interest earned from the investment at 3%, we multiply x by 3% (0.03). Similarly, the interest earned from the investment at 4% is calculated by multiplying ($4000 - x) by 4% (0.04).

According to the given information, the total interest earned from both investments is $130. So we can set up the equation:

0.03x + 0.04($4000 - x) = $130

Simplifying the equation:

0.03x + 0.04($4000 - x) = $130

0.03x + $160 - 0.04x = $130

-0.01x = $130 - $160

-0.01x = -$30

x = -$30 / -0.01

x = $3000

Therefore, you invested $3000 at 3% annual interest rate, and the remaining amount of $4000 - $3000 = $1000 was invested at 4% annual interest rate.
