E=mo^2 solve for m ...............................................

Answer:

The solution is:

\(y=7,\:x=3\)

Step-by-step explanation:

I think substitution method would be the best method for solving the given system of equations.

The reason is that all we need is to plug in the the value of y i.e. y=x+4 in the equation 3x – 4y = -19, then solve for x, and in the end substitute the value x in the equation y=x+4 to get the y-value.

The other method, elimination method, can also be used, but elimination method in current system of the equations would involve a certain degree of arrangements of the variables and then different multiplying of the equation to eliminate the variables.

Thus, I think substitution method would be the best method for solving the given system of equations.

Let us solve using substitution method

\(\begin{bmatrix}y=x+4\\ 3x-4y=-19\end{bmatrix}\)

\(\mathrm{Subsititute\:}y=x+4\)

\(\begin{bmatrix}3x-4\left(x+4\right)=-19\end{bmatrix}\)

\(\begin{bmatrix}-x-16=-19\end{bmatrix}\)

\(x=-16+19\)

\(x=3\)

Now, just substitute x=3 in y=x+4

\(y=x+4\)

\(y=3+4\)

\(y=7\)

Thus, the solution is:

\(y=7,\:x=3\)

Answer:

C = 7.72 ~ 7.7

Step-by-step explanation:

So when you solve this equetion you must 1st find x then c

we can find x by using cos(60)

cos(60) = x/14

x = cos(60) × 14

x = 1/2 ×14

x = 7

so after we find x we are going to solve c by using cos (25)

cos (25) = X/C = 7/c

cos(25) × C = 7

C = 7/cos (25)

C = 7.72 ~ 7.7

so the solution is 7.7

In 10 seconds, Ruben will have hopped a total distance of 40 yards (10 * 4 = 40) to overtake Judy in the race.

Ruben will have to hop a total distance of 40 yards to overtake Judy in the potato sack race.

To determine the distance Ruben needs to cover, we first need to calculate the time it takes for Ruben to catch up with Judy. Since Judy has a head start of 20 yards, Ruben needs to close this gap to overtake her.

Judy's rate of hopping is 2 yards per second, while Ruben's rate is 4 yards per second. Therefore, Ruben is gaining on Judy at a rate of 2 yards per second (4 - 2 = 2).

Since the head start is 20 yards, Ruben will catch up with Judy in 10 seconds (20 / 2 = 10). During this time, Ruben will be hopping at a rate of 4 yards per second.

Answer:

\(64\frac{1}{8}\)

Step-by-step explanation:

Convert mixed numbers to improper fractions, this is done by taking the denominator multiplying it by the whole number and adding that to the numerator. The denominator is kept the same

4 * 2 = 8 + 1 = 9

9/4

8 * 5 = 40 + 7 = 47

47/8

Use the LCM to be able to add both fractions. The LCM is 8

47/8 already has a denominator of 8, so only 9/4 has to be changed

9 * 2 = 18

4 * 2 = 8

Simplify

47/8 + 18/8

Add the numerators

47 + 18 = 65/8

Convert the improper fraction back to a mixed number

This is done by multiplying to the highest extent and placing the remainder as the numerator, the denominator is untouched.

8 * 8 = 64, we have a remainder of 1, which is the numerator. The denominator is untouched.

Simplify

64 1/8

The answer is 64 1/8

Answer:

The probability of drawing a face card or a 4 is approximately 0.2885, or 28.85%.

Step-by-step explanation:

To find the probability of drawing a face card or a 4 from a well shuffled deck of 52 cards, we need to count the number of cards that are either a face card or a 4, and divide that number by the total number of cards in the deck.

There are 12 face cards in a deck (4 kings, 4 queens, and 4 jacks) and 4 cards with the number 4, but the card with 4 is also a face card (the four of hearts), so we need to subtract one card from the total. Therefore, there are 15 cards in the deck that are either a face card or a 4.

The total number of cards in the deck is 52. Therefore, the probability of drawing a face card or a 4 from a well shuffled deck of cards is:

P = number of desired outcomes / total number of possible outcomes P = 15/52 P = 0.2885 (rounded to four decimal places)

So the probability of drawing a face card or a 4 is approximately 0.2885, or 28.85%.

According to the equation we have After simplifying, the equation in spherical coordinates is: 5ρ^2 - 3ρ sin(θ) cos(φ) = 0 .

To write the given equation in spherical coordinates, we first need to express x, y, and z in terms of rho (ρ), theta (θ), and phi (φ), which are the spherical coordinates.

We know that:

x = ρsinφcosθ
y = ρsinφsinθ
z = ρcosφ

Substituting these values in the given equation, we get:

5(ρsinφcosθ)² - 3(ρsinφcosθ) + 5(ρsinφsinθ)² + 5(ρcosφ)² = 0

Simplifying further, we get:

5ρ²sin²φcos²θ + 5ρ²sin²φsin²θ + 5ρ²cos²φ - 3ρsinφcosθ = 0

Now, we can use the trigonometric identities:

sin²θ + cos²θ = 1
sin²φ + cos²φ = 1

Substituting these in the equation, we get:

5ρ²sin²φ + 5ρ²cos²φ - 3ρsinφcosθ = 0

To rewrite the given equation 5x^2 - 3x + 5y^2 + 5z^2 = 0 in spherical coordinates, we need to use the conversions:

x = ρ sin(θ) cos(φ)
y = ρ sin(θ) sin(φ)
z = ρ cos(θ)

Substitute these conversions into the equation:

5(ρ sin(θ) cos(φ))^2 - 3(ρ sin(θ) cos(φ)) + 5(ρ sin(θ) sin(φ))^2 + 5(ρ cos(θ))^2 = 0

After simplifying, the equation in spherical coordinates is:

Answer:

  ∆APQ is isosceles, so sides AP, AQ are congruent

Step-by-step explanation:

You want to show that AP≅AQ in the given figure.

The Angles of Intersecting Chords Theorem tells you that the angle where chords cross is half the sum of the intercepted arcs. Here, that means ...

  ∠APY = (arc BX +arc AY)/2

  ∠AQX = (arc AX +arc CY)/2

Given that arc AX ≅ arc BX, and arc AY ≅ arc CY, we can substitute for BX and CY to get ...

  ∠APY = (arc AX +arc AY)/2

  ∠AQX = (arc AX +arc AY)/2

Two angles equal to the same thing are equal (substitution property), so ...

  ∠APY ≅ ∠AQX

These are base angles in the isosceles triangle APQ, so their opposite sides, AQ and AP, respectively, are congruent.

  AP ≅ AQ

One common unit of measure that serves as a conversion factor between linear and angular measurements is the radian (rad).

A radian is defined as the angle subtended at the center of a circle by an arc of the circle equal in length to the radius of the circle.

Since the circumference of a circle is 2π times the radius, there are 2π radians in a full circle. Therefore, one can use the following conversion factors

1 radian = 180/π degrees (approx. 57.3 degrees)

1 degree = π/180 radians (approx. 0.01745 radians)

These conversion factors allow you to convert between linear measurements (such as arc length or circumference) and angular measurements (such as angles in degrees or radians) when dealing with circular motion or rotational systems.

Bayes' Theorem is a mathematical theorem that enables the revision of prior probabilities based on new information or evidence.

This theorem is widely used in statistics, machine learning, and other fields that deal with uncertainty and probabilistic reasoning. Contrary to the first option mentioned in the question,

Bayes' Theorem can be used when conditional probabilities are known, and it enables the calculation of posterior probabilities, which is the probability of a hypothesis or event given the available evidence.

Therefore, the third option is correct; Bayes' Theorem enables the use of sample information to revise prior probabilities. This theorem is highly valuable because it allows the integration of new data or knowledge into the decision-making process,

which can lead to more accurate predictions and better-informed decisions. In summary, Bayes' Theorem is a powerful tool that requires knowledge of probabilities and enables the calculation of posterior probabilities based on new evidence or information.

By combining prior probabilities with likelihoods (based on new data), we can calculate posterior probabilities, which represent our updated knowledge.

This process is crucial in making informed decisions in various fields, such as data science, finance, and medical diagnosis.

Answer:

The correct equation to solve for "x" is:

\(x^2+8x-308=0\)

(first option in your list)

Step-by-step explanation:

Let's say that since the integers in question are separated on the number line, we can call them x, and y with for example y being the larger one (two the right of x on the number line). Since the two integers are 8 units apart, then we can write in mathematical form:

y - x = 8 (because y is the larger of the two numbers)

and solving for "y" we get:

y = x + 8

we also know that their product is 308, which we can write in the following form:

x * y = 308

Now, replacing y by "x + 8", we get:

\(x*y=308\\x\,(x+8)=308\\x^2+8x=308\\x^2+8x-308=0\)

Therefore, the correct equation is the first one listed among your answer options.

\(\frac{12}{2}=6\)

So Michael is 6 years old.

The largest possible value in the list is 35.

What is mean, median and mode?

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean. An average is most frequently used to refer to this. The middle value in a list that is arranged from smallest to greatest is called the median. The value that appears the most frequently on the list is the mode.

Given: There is a list of 11 positive integers.

Has a mean of 10, a median of 9 and a unique mode of 8.

Since the mode (8) is less than the median (9), the mode can only appear (at most) 5 times since the mode is the 6th number in the list (assuming the list has been sorted in ascending order).

If so, the first five numbers can be 8, the following four numbers can be 9, and the next greatest number can be 10, which means the largest number must be 110 - (8 x 5 + 4 x 9 + 10) = 110 - 86 = 24.

The largest number must be 110 - 77 = 33 if the mode repeats just twice, in which case we can let the first ten numbers be 1, 2, 3, 8, 8, 9, 10, 11, and 13, totaling 77.

The biggest number in this scenario is 110 - 75 = 35 if the mode repeats itself three times. Alternatively, we can let the first ten numbers be 1, 1, 8, 8, 8, 9, 10, 10, and 11 totaling 75.

Therefore, the largest possible value of an integer in the list is, 35.
