Answer:

The salesperson needs to sell 10 stereos to make the same money on both plans

Step-by-step explanation:

We'll analyze both choices for the compensation plans of a salesperson.

One plan offers a fixed weekly salary of $250 plus a $25 commission for each stereo sold. The function than models this plan is:

P1=250+25x

Where x is the number of stereos sold.

The other plan offers no fixed salary but a $50 commission on each stereo sold. The function of this plan is:

P2=50x

To find the equilibrium point for both plans, we make P1=P2:

250+25x=50x

Simplifying:

25x=250

Solving:

x = 250 / 25 = 10

The salesperson needs to sell 10 stereos to make the same money on both plans

According to the values in the table, no, x and y does not have a proportional relationship. Therefore, the correct answer option is: B. no.

In Mathematics, a proportional relationship is a type of relationship that generates equivalent ratios and it can be modeled or represented by the following mathematical expression:

y = kx

Where:

Next, we would determine the constant of proportionality (k) for the relationship between the x-values and y-values in this table as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 93/1.1 ≠ 95/1.3 ≠ 98/1.6 ≠ 100/1.8

Since the constant of proportionality (k) for the relationship between the x-values and y-values are different, we can logically deduce that this is not a proportional relationship.

The foil was approximately 3.4 × 10⁷ atoms thick.

Rutherford's foil was made of gold and was used in his famous alpha particle scattering experiment. The thickness of the foil can be calculated by dividing its actual thickness by the diameter of a single gold atom.

Let's assume that the gold atoms in the foil are arranged in a simple cubic lattice. In this case, the actual thickness of the foil can be calculated as the number of gold atoms along one edge of the cube times the diameter of a single gold atom:

actual thickness = number of atoms × diameter of a single atom

To calculate the number of gold atoms, we need to know the density of gold and the mass of the foil. Let's assume that the density of gold is 19.3 g/cm³ and the mass of the foil is 0.6 mg = 6.0 × 10⁻⁷ kg.

The volume of the foil can be calculated as its mass divided by its density:

volume = mass / density = 6.0 × 10⁻⁷ kg / (19.3 × 10³ kg/m³) = 3.11 × 10⁻¹⁰ m³

The volume of the foil is also equal to the product of its actual thickness, the area of one face of the cube (which is the square of the number of atoms along one edge), and the volume of a single gold atom (which is (4/3)πr³, where r is the radius of the atom):

volume = actual thickness × (number of atoms)² × (4/3)πr³

Substituting the diameter of a single gold atom (2.9 × 10⁻¹⁰ m) for 2r, we get:

volume = actual thickness × (number of atoms)² × (4/3)π(1.45 × 10⁻¹⁰ m)³

Equating the two expressions for the volume of the foil, we get:

actual thickness × (number of atoms)² × (4/3)π(1.45 × 10⁻¹⁰ m)³ = 3.11 × 10⁻¹⁰ m³

Solving for the number of atoms, we get:

number of atoms = √(3.11 × 10⁻¹⁰ m³ / [(4/3)π(1.45 × 10⁻¹⁰ m)³]) ≈ 3.4 × 10⁷

So the foil was approximately 3.4 × 10⁷ atoms thick.

The expression that gives the combined area of the garden and the drainage strip is 36 + 2h(6 + 2h).

To find the expression for the combined area of the garden and the drainage strip, we need to consider the area of the garden and the area of the strip separately, and then add them together.

Let's start by calculating the area of the garden. Since the garden is square, the length of each side is equal to its width, which is given as 6 meters. The area of the garden can be calculated using the formula for the area of a square: side length squared.

Area of the garden = (side length)^2 = (6 meters)^2 = 36 square meters.

Now let's consider the drainage strip. The drainage strip surrounds the garden, and its width is given as h meters. Since the strip runs along the perimeter of the garden, we need to add the width of the strip to each side of the garden to account for the total dimensions.

The length of each side of the combined garden and strip will be increased by 2h meters, considering the h-meter width on both sides. Therefore, the length of each side becomes (6 meters + 2h meters).

The area of the drainage strip can be calculated using the formula for the area of a rectangle: length times width.

Area of the drainage strip = (length of each side) * (width of strip) = (6 + 2h) meters * h meters = 2h(6 + 2h) square meters.

Finally, to obtain the combined area of the garden and the drainage strip, we add the area of the garden and the area of the strip:

Combined area = Area of the garden + Area of the drainage strip = 36 square meters + 2h(6 + 2h) square meters.

Therefore, the expression that gives the combined area of the garden and the drainage strip is 36 + 2h(6 + 2h).

Stacy has 16 flowers in total

She has 4 vases

This implies that each of the vase will contain 4 flowers each

To determine the number of flowers in each verse

Number of flowers = Total number of flowers / Total number of vases

Total flower = 16

Total number of vases = 4

Number of flowers = 16 / 4

Since 4 is a multiple of 16

Therefore, 16 / 4 = 4

The answer is 4 flowers

Stacy will put 4 flowers each in each vase

According to the given information, the solutions to the equation 7x²-34=2x²+16 are x = √10 and x = -√10.

What is quadratic equation?

A quadratic equation is a second-degree polynomial equation of the form ax² + bx + c = 0 where a, b, and c are constants, and x is the variable.

To solve for x in the equation 7x²-34=2x²+16 using square roots, we can first simplify the equation by moving all the x² terms to one side and all the constant terms to the other side:

7x² - 2x² = 16 + 34

5x² = 50

5x²/5 = 50/5

x² = 10

Finally, we can take the square root of both sides (remembering to include both the positive and negative square root, since x could be positive or negative):

x = ±√10

Therefore, the solutions to the equation 7x²-34=2x²+16 are x = √10 and x = -√10.

The distance a car can drive is not a discrete random variable but a continuous random variable.

The distance a car can drive is not a discrete random variable.

A discrete random variable is one that can take on a countable number of distinct values.

Examples of discrete random variables include the number of smarties in a box, the number of students in a college class, and individuals' shoe sizes (which can be measured in whole numbers or specific sizes).

These variables have finite or countably infinite possible values.

On the other hand, the distance a car can drive is a continuous random variable. It can take on any value within a range (e.g., 0 miles to the maximum distance the car can travel), and there are infinitely many possible values within that range.

Continuous random variables are associated with measurements and can take on any value within a specified range, often involving real numbers.

Therefore, the distance a car can drive is not a discrete random variable but a continuous random variable.

The polynomial for the perimeter of the rectangle can be expressed as P(n) = 2(2n+8) + 2(n-7), which simplifies to P(n) = 4n + 16 + 2n - 14.

Combining like terms, we get P(n) = 6n + 2. Therefore, the polynomial in standard form for the perimeter of the rectangle is P(n) = 6n + 2.

To find the perimeter of the rectangle, we need to add up the lengths of all four sides. The length of the rectangle is represented by 2n+8, so we have 2 sides of length (2n+8). The width of the rectangle is represented by n-7, so we have 2 sides of length (n-7). To calculate the perimeter, we add up the lengths of all four sides: (2n+8) + (2n+8) + (n-7) + (n-7). Simplifying this expression, we get 6n + 2, which is the polynomial in standard form for the perimeter of the rectangle.

The simplified radical expression by rationalizing the denominator is, \(\frac{-6}{\sqrt{5y}}\times\frac{\sqrt{5y}}{\sqrt{5y}}\) = \(\frac{-6\sqrt{5y}}{5y}$$\) = $\frac{-6\sqrt{5y}}{5y}$.

To simplify the radical expression by rationalizing the denominator, multiply both numerator and denominator by the conjugate of the denominator.

The given radical expression is \($\frac{-6}{\sqrt{5y}}$\).

Rationalizing the denominator

To rationalize the denominator, we multiply both the numerator and denominator by the conjugate of the denominator, \($\sqrt{5y}$\)

Note that multiplying the conjugate of the denominator is like squaring a binomial:

This simplifies to:

(-6√(5y))/(√(5y) * √(5y))

The denominator simplifies to:

√(5y) * √(5y) = √(5y)^2 = 5y

So, the expression becomes:

(-6√(5y))/(5y)

Therefore, the simplified expression, after rationalizing the denominator, is (-6√(5y))/(5y).

\($(a-b)(a+b)=a^2-b^2$\)

This is what we will do to rationalize the denominator in this problem.

We will multiply the numerator and denominator by the conjugate of the denominator, which is \($\sqrt{5y}$\).

Multiplying both the numerator and denominator by \($\sqrt{5y}$\), we get \(\frac{-6}{\sqrt{5y}}\times\frac{\sqrt{5y}}{\sqrt{5y}}\) = \(\frac{-6\sqrt{5y}}{5y}$$\)
