Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

The rule of the sides of a triangle is that the sum of the lengths of any two sides of a triangle is always greater than the length of the third side. This rule is also known as the triangle inequality theorem.

The true or false statements based on the graph on the lengths of ribbons are:

The graph shows that most common length that a ribbon has is 11²/₈ with 3 ribbons. At a simpler term, this becomes 11¹/₄.

The sum of the longest and shortest lengths is:

= 11¹/₄ + 9⁷/₈

= 21⁹/₈

The sum is therefore not 20¹/₈.

The difference between the longest and shortest lengths is:

= 11¹/₄ - 9⁷/₈

= 1³/₈

For the measures of these angles to be integral, (n-2) times 180 must be divisible by n.

An n-sided regular polygon has interior angles that measure (n-2) times 180 degrees divided by n. This means that n must be a divisor of (n-2) times 180, or that n must be a divisor of 180. The only positive integers that divide 180 are 1, 2, 3, 4, 5, 6, 9, 10, 15, 18, 30, and 180.

So the only values of n for which an n-sided regular polygon has interior angles with integral measures are 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, and 20.

Therefore, the solution to Equation (5) is:

\(V_y(x, y, t) = ± √(m^2 - 5m/q^2) exp(±imV_B t + i sin(y))\)

To solve the given partial differential equations, we will start by solving Equation (4) and then use the solution to solve Equation (5). Let's go through the steps:

Step 1: Solve Equation (4):

We are given the equation:

∂^2V_x/∂t^2 = - (mV_B)^2V_x

To solve this equation, we assume a solution of the form V_x(x, y, t) = V_1 exp(±iω_c t + i sin(y))

Substituting this solution into Equation (4), we get:

\((-ω_c^2) V_1 exp(±iω_c t + i sin(y)) = - (mV_B)^2 V_1 exp(±iω_c t + i sin(y))\)

Dividing both sides by V_1 exp(±iω_c t + i sin(y)), we obtain:

\(-ω_c^2 = - (mV_B)^2\)

Simplifying, we get:

ω_c = ± mV_B

Therefore, the solution to Equation (4) is:

V_x(x, y, t) = V_1 exp(±imV_B t + i sin(y))

Step 2: Solve Equation (5):

We are given the equation:

\(∂^2V_y/∂t^2 = - (m/qz)^2 V_y - 5 V(x, y)\)

Using the solution from Step 1, we have:

V(x, y) = V_1 exp(±imV_B t + i sin(y))

Substituting this into Equation (5), we get:

\((-ω_c^2) V_1 exp(±imV_B t + i sin(y)) = - (m/qz)^2 V_y - 5 V_1 exp(±imV_B t + i sin(y))\)

Dividing both sides by V_1 exp(±imV_B t + i sin(y)), we obtain:

\(-ω_c^2 = - (m/qz)^2 - 5\)

Substituting ω_c = ± mV_B, we have:

\(-(mV_B)^2 = - (m/qz)^2 - 5\)

Simplifying, we get:

\((qz)^2 = m^2 - 5m/q^2\)

Taking the square root, we have:

\(qz = ± √(m^2 - 5m/q^2)\)

Therefore, the solution to Equation (5) is:

\(V_y(x, y, t) = ± √(m^2 - 5m/q^2) exp(±imV_B t + i sin(y))\)

Please note that the given solution in the photograph may have different notations or formatting, but the steps outlined above demonstrate the process to solve the equations and arrive at the solution in terms of V(x, y).

multiply the newest quotient digit (1) by the divisor two.

subtract 2 by 3.

Answer:

The bill was $36.95 without tax.

The price before tax was the amount of $37.25 which is before a 9% sales tax was added to their bill.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Their bill was charged a 9% sales tax.

Amy paid the bill with a $10 gift certificate plus $30.60

Use the equation P + rP =T,

where P is the price before tax, r is the sales tax rate, and T is the total price, including tax.

The price before tax (P) is unknown.

The total price(T) = 30.60 + 10 = 40.60

The sales tax rate (r) = 9% = 9/100 = 0.09

⇒ P + rP = T

Substitute the values in the above equation, and we get

⇒ P + (0.09)P = 40.60

⇒ P(1 + 0.09) = 40.60

⇒ P(1.09) = 40.60

⇒ P = 30.60/(1.09)

Apply the Division operation, and we get

⇒ P = 37.247706

Rounded to the nearest hundredth

⇒ P = 37.25

Therefore, the price before tax was the amount of $37.25.

The equation of the parabola with focus (2,5) and directrix x=18 is (x - 18)² + (y - 5)² = (y - (5 + (18 - 2) / 2))².

A parabola is a conic section, the intersection of a right circular conical surface and a plane parallel to a generating

straight line of that surface.

The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.

The directrix is a straight line perpendicular to the axis of symmetry and placed symmetrically with respect to the focus.

The axis of symmetry is the line through the focus and perpendicular to the directrix.

The vertex of a parabola is the point where its axis of symmetry intersects the curve. It is the point where the parabola changes direction or "opens

up" or "opens down.

The directrix is a fixed straight line used in the definition of a

parabola. It is placed such that it is perpendicular to the axis of symmetry and at a distance from the vertex equal to the

distance between the vertex and focus. It is the line that is equidistant to the focus and every point on the curve.Here's

the solution to the given problem:

The distance between the directrix and the focus is equal to p = 16 (since the directrix is x = 18, the parabola opens to the left, so the distance is measured horizontally)

The vertex is (h,k) = ((18+2)/2,5) = (10,5)

Then we can use the following formula: (x - h)² = 4p(y - k)

Substitute the vertex and the value of p. (x - 10)² = 64(y - 5)

Expand and simplify. (x - 10)² + (y - 5)² = 64(y - 5)

The equation of the parabola is (x - 10)² + (y - 5)² = 64(y - 5).

The surface area of the given right cone is approximately 232.4584 m².

To find the surface area of a right cone, you need to calculate the sum of the lateral surface area and the base area. The lateral surface area of a cone is given by the formula A = πrl, where π is approximately 3.14, r is the radius of the base, and l is the slant height of the cone. The base area of a cone is given by the formula A = πr².

Given that the radius of the base of the cone is 5 m, we can calculate the slant height using the Pythagorean theorem. The slant height is the hypotenuse of a right triangle formed by the height (h) and the radius (r) of the cone. We can calculate the slant height (l) as l = √(r² + h²).

Let's calculate the slant height:

l = √(5² + 8.4²)

= √(25 + 70.56)

= √95.56

≈ 9.776 m (rounded to three decimal places)

Now we can calculate the lateral surface area (A_lateral) and the base area (A_base):

A_lateral = πrl

≈ 3.14 × 5 × 9.776

≈ 153.9584 m² (rounded to four decimal places)

A_base = πr²

= 3.14 × 5²

= 3.14 × 25

≈ 78.5 m²

To find the total surface area (A_total), we sum the lateral surface area and the base area:

A_total = A_lateral + A_base

≈ 153.9584 + 78.5

≈ 232.4584 m² (rounded to four decimal places)

The distance between points (4,6) and (4,-1) is 7 units.

Given The coordinates of the end points of line (4,6) and (4,-1).

Distance is the measurement about how far things are present on the surface. It is usually calculated in some units known as km, m, etc.

The distance between two points can be calculated as under:

Distance=\(\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }\) where the coordinates are (x1,y1),(x2,y2).

To calculate the distance we need to put the values of coordinates in the formula:

Distance between (4,6) and (4,-1)=\(\sqrt{(4-4)^{2} +(-1-6)^{2} }\)

=\(\sqrt{(0)^{2}+(-7)^{2} }\)

=\(\sqrt{0+49}\)

Step-by-step explanation: cuz im smart and said so

The collection of sample averages, known as the sampling distribution, would have an average that is equal to the average height of the entire population.

When measuring the height of each team and calculating their average, we are essentially taking samples from the population of all teams. The sampling distribution is created by repeating this process multiple times and calculating the average for each sample. According to the central limit theorem, as the sample size increases, the sampling distribution approaches a normal distribution regardless of the shape of the population distribution.

Therefore, the average of the sampling distribution, which represents the average height of all teams, would be equal to the average height of the entire population. The sampling distribution allows us to make inferences about the population based on the collected samples and provides a measure of the variability of the sample averages.

The probability that at least 15 in the sample are among the group of athletes who have been told by coaches to neglect their studies is approximately 0.0998.

Probability can be used to make predictions or decisions in a variety of situations, such as in gambling, finance, and science. In these situations, probabilities can be calculated based on statistical data or by using mathematical models.

To find the probability that at least 15 in the sample are among the group of athletes who have been told by coaches to neglect their studies, we can use the binomial cumulative distribution function. This is given by:

$$P(X \ge 15) = \sum_{k=15}^{50} \binom{50}{k} (0.4)^k (0.6)^{50-k}$$

We can calculate this probability using a calculator or computer, or we can approximate it using the normal distribution. To do this, we can use the continuity correction and compute:

$$P(X \ge 15) \approx P\left(\frac{X-n p}{\sqrt{n p (1-p)}} \ge \frac{15 - 50 \cdot 0.4}{\sqrt{50 \cdot 0.4 \cdot 0.6}}\right) = P(Z \ge 1.28)$$

Where $Z$ is a standard normal random variable. Using a standard normal table or calculator, we find that $P(Z \ge 1.28) \approx 0.0998$.

To calculate the number of feet of fencing Melissa needs to enclose a square area of 5652 square feet, we need to determine the length of the sides of the square.

Since a square has four equal sides, we can find the length of one side by taking the square root of the area. In this case, the square root of 5652 is approximately 75.16 feet.

To calculate the total length of fencing needed, we multiply the length of one side by 4 (as there are four sides in a square). Therefore, Melissa would need approximately 300.64 feet of fencing (75.16 feet x 4) to enclose the square area of 5652 square feet.

It's important to note that this calculation assumes a perfect square shape with no irregularities or additional considerations such as gates or overlapping sections. Additionally, it's always a good idea to add a little extra footage to account for any errors or contingencies during installation.
