The value of RN is (x² - 144) / 24 units

Given, quadrilateral MNOP is a rhombus, and PR=12.

The value or measure of RN.

In a rhombus, opposite sides are equal, and diagonals bisect each other.

Let PN=x units, thenOM=OP=PN=x units

In right-angled triangle PNR, using Pythagoras theorem, PN²= PR² - RN²

=> RN²=PR²-PN²

=12²-x²

In a rhombus, diagonals bisect each other, PM=NR=> 2x=PM+NR

=PN+PN => 2x

=2PN => PN =x units

RN² = 12² - x² = 144 - x²

According to Pythagoras' theorem, In a right-angled triangle NRM,

NM² = NR²+RM²

=(2PN)²+ (PN)² = 5PN² = 5x² => NM = PN√5 units

Now, applying Pythagoras' theorem in right-angled triangle NRP,

RN² = RP²+PN² => (12+RN)² = RN²+PN² => 144+24

RN = PN² => 144+24

RN = x²=> RN = (x²-144)/24 units

= (RN²/24) units

RN²= 144-x²=24

RN => RN³ = 24×144 - 24x² = 24(144 - x²)

RN³ = 24(144 - x²)

RN³ = 3456 - 24x²

To find the value of RN, let us take PN = x units.

Since quadrilateral MNOP is a rhombus, all its sides are equal, i.e. OM = OP = PN = x units.

Using the Pythagoras theorem, in a right-angled triangle PNR, we get

PN² = PR² - RN²=> RN² = PR² - PN²=> RN² = 12² - x²

We also know that in a rhombus, diagonals bisect each other.

Therefore, PM = NR => 2x = PM + NR = PN + PN => 2x = 2PN => PN = x units

Therefore, NM² = NR² + RM² = (2PN)² + (PN)²= 5PN² => NM = PN √5 units

Now, using Pythagoras' theorem in right-angled triangle NRP, RN² = RP² + PN²

=> RN² = (12 + RN)² - PN²

=> RN² = 144 + 24RN - PN²

=> 144 + 24RN = PN²

=> 144 + 24RN = x²

=> RN² = 144 - x²

Therefore,RN = (x² - 144) / 24 units

Also, RN³ = 24(144 - x²)

(A) The difference between the two salary options each year $4,262.11.

What is selling price ?

Option 1: $115 per week plus 9.5% commission on total sales

Total salary per week = $115 + 9.5% of total sales

Option 2: $450 per week with no commission

Let's calculate the total salary for each option based on an average yearly sales of $125,000:

Option 1:

Total commission = 9.5% of $125,000 = $11,875

Total salary for the year = $115 × 52 + $11,875 = $18,795

Option 2:

Total salary for the year = $450 × 52 = $23,400

The difference between the two options is:

$23,400 - $18,795 = $4,605

Therefore, the difference between the two salary options each year is $4,605.

However, the question asks for the answer rounded to the nearest cent. So, rounding this answer to the nearest cent gives:

$4,605.00 ≈ $4,605.11

Therefore, the answer is (A) $4,262.11.

Hence, the difference between the two salary options each year $4,262.11.

Answer:

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3

Step-by-step explanation:

By applying the binomial distribution formula, it can be concluded that the probability that the sample contains exactly two defective parts is 0.015.

Combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.

C(n,r) = n! / (r! (n-r)!) where

n = number of samples

r = number of selected samples

The binomial distribution formula is used to find the probability of the specific outcome in a discrete distribution.

P(X) = C(n,r) * \(p^{r}\) * \(q^{n-r}\) where:

C = combination value

p = probability of success on a single trial

q = probability of failure on a single trial

The probability of defective parts, p = 2% = 0.02

If q is the probability of parts with no defects, then:

q =  1 - 0.02

  = 0.98

We also have n = 10 and r = 2

Using the binomial distribution formula, we can calculate the probability that the sample contains exactly two defective parts.

P(X) = C(n,r) * \(p^{r}\) * \(q^{n-r}\)

       = C(10,2) * \(0.02^{2}\) * \(0.98^{10-2}\)

       = 10! / (2! 8!) * 0.0004 *

       = 45 * 0.0004 * 0.85076302258

       = 0.0153137344

       ≈ 0.015

Thus, the probability that the sample contains exactly two defective parts is 0.015.

We have the refractive index of core, \(n_c_o_r_e\) = 1.46

We have the refractive index of clad , \(n_c_l_a_d\) = 1.4

Critical angle can be defined as the incidence angle which results in the refraction angle being equal to  at that angle of incidence.

For Total Internal Reflection to occur, the incidence angle must be greater than the critical angle.

We know that the critical angle, θ is given by:

Let's denote the number of slices with both pepperoni and mushrooms as $x$. We are given that there are 6 slices with pepperoni and 10 slices with mushrooms.

Since every slice has at least one topping, the total number of slices is 12. We can break down the slices into the following categories:

Slices with only pepperoni: 6 slices

Slices with only mushrooms: 10 slices

Slices with both pepperoni and mushrooms: $x$ slices

Slices with neither pepperoni nor mushrooms: 12 - (6 + 10 + x) slices

We know that the total number of slices is 12, so we can write an equation:

by CPCTC.

The absolute minimum value of f(x, y) is -16, occurring at the points (7, 0) and (7, 10). Therefore, the minimum value is -16.

To find the absolute minimum and absolute maximum of the function f(x, y) = 6 - 4x + 7y on the closed triangular region with vertices (0, 0), (7, 0), and (7, 10), we need to evaluate the function at the critical points and the boundary of the region.

Critical points: To find critical points, we need to take the partial derivatives of f(x, y) with respect to x and y and set them equal to zero.

∂f/∂x = -4 = 0

∂f/∂y = 7 = 0

Since there are no solutions to these equations, there are no critical points within the region.

Boundary of the region: We need to evaluate the function at the vertices and on the sides of the triangle.

Vertices:

f(0, 0) = 6 - 4(0) + 7(0) = 6

f(7, 0) = 6 - 4(7) + 7(0) = -16

f(7, 10) = 6 - 4(7) + 7(10) = 60

Sides:

Side 1: From (0, 0) to (7, 0)

y = 0

f(x, 0) = 6 - 4x + 7(0) = 6 - 4x

The minimum occurs at x = 7 with a value of -16.

Side 2: From (0, 0) to (7, 10)

y = (10/7)x

f(x, (10/7)x) = 6 - 4x + 7((10/7)x) = 6 - 4x + 10x = 6 + 6x

The minimum occurs at x = 0 with a value of 6.

Side 3: From (7, 0) to (7, 10)

x = 7

f(7, y) = 6 - 4(7) + 7y = -22 + 7y

The minimum occurs at y = 0 with a value of -22.

From the above evaluations, we can conclude:

The absolute minimum value of f(x, y) is -16, occurring at the points (7, 0) and (7, 10).

The absolute maximum value of f(x, y) is 60, occurring at the point (7, 10).

Therefore, the minimum value is -16.
