right ascension 15 06 53.62 declination 62 20 10.0 1

Answers

Answer 1

The celestial coordinates of the given point are (0.92868, 0.36983, 0.04921).

The right ascension and declination of a particular point in the sky can be used to calculate its corresponding celestial coordinates. Right ascension (RA) is measured in hours, minutes and seconds, while declination (Dec) is measured in degrees, minutes and seconds.

The RA of the given point is 15 h 06 m 53.62 s. This can be converted to degrees by multiplying by 15. The result is 225.1045 degrees. The Dec of the given point is 62° 20' 10.0" which can be converted to radians by multiplying by pi/180. The result is 1.08269 radians.

The celestial coordinates can then be calculated using the formula:

sin(RA)cos(Dec) = sin(225.1045)*cos(1.08269) = 0.92868

cos(RA)cos(Dec) = cos(225.1045)*cos(1.08269) = 0.36983

sin(Dec) = sin(1.08269) = 0.04921

Therefore the celestial coordinates of the given point are (0.92868, 0.36983, 0.04921).

In a circle with radiu 2. 2, an angle intercept an arc of length 12. 2. Find the angle in radian to the nearet 10th

Answers

In geometry, an angle is often measured in units of radians, which is a way to express the size of an angle in terms of the length of the arc it cuts off on the circumference of a circle.

This relationship between an angle and an arc length is given by the formula:

Arc Length = Radius * Angle (in radians)

Rearranging this formula to solve for the angle, we have:

Angle (in radians) = Arc Length / Radius

Plugging in the values for the radius (2.2) and the arc length (12.2), we get:

Angle (in radians) = 12.2 / 2.2 = 5.54

Rounding to the nearest 10th, the angle in radians is approximately 5.5.

if you add 10 to every value of a data set, what happens to the standard deviation?

Answers

The standard deviation of the data set will increase by a factor of 10. This is because standard deviation measures how much variation or dispersion exists from the mean of a data set. Adding 10 to every value of the data set will increase the overall spread of the data and thus increase the standard deviation.  

To prove this mathematically, let's consider a data set A with mean M and standard deviation SD. Let's add 10 to every value of the data set to get a new data set B. The mean of set B is M+10 and the standard deviation of set B is SD'.   The formula for SD' is:  

SD':[tex]\sqrt{(x_{1} -(M+10))^{2} +(x_{2} -(M+10))^2+ (x_{3}-(M+10))^2 +...+ (x_{n}-(M+10))^2)/n }[/tex] We can simplify this by substituting the values for the xi:

 SD' =[tex]\sqrt{(((x_{1}-M-10)^2 + (x_{2}-M-10)^2 + (x_{3}-M-10)^2 +...+ (x_{n}-M-10)^2)/n) }[/tex]  Now let's consider the original data set A and its standard deviation SD:

 SD =[tex]\sqrt{(((x_{1}-M)^2 + (x_{2}-M)^2 + (x_{3}-M)^2 +...+ (x_{n}-M)^2)/n) }[/tex] ,We can substitute the values for xi in this formula as well:  

SD= [tex]\sqrt{ (((x_{1}-M-10)^2 + (x_{2}-M-10)^2 + (x_{3}-M-10)^2 +...+ (x_{n}-M-10)^2)/n)}[/tex]  If we compare SD and SD', we can see that they are identical, except that the value of M has been replaced with M+10. This means that when we add 10 to every value of the data set, the standard deviation increases by a factor of 10.

LESSON. 3.7. Practice B. For use with pages 176-181. Use a proportion to answer the question. 1. What percent of 125 is 25? 2. What percent of 70 is 14?

Answers

The percent of 125 is 25 when it is 20% and 70 is 14 when it is 20%

How to find the percentage?

To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.

To calculate the percentage of a number, we need to use a different formula such as:

P% of Number = X, where X is the required percentage.

If we remove the % sign, then we need to express the above formula as;

P/100 * Number = X

What percent of 125 is 25 and percent of 70 is 14?

Given:

To solve this, we need to set up a proportion. We know 25 is a certain percent of 125, and we want to find what that percent is.

So, we set up the proportion 25/125 = x/100, where x is the percent, we are looking for.

Now we can cross-multiply to solve for x.

We get 25 x 100 = 125 x, so x = [tex]\frac{25 \times 100}{125}[/tex], x = 20

Therefore, 25 is 20% of 125.

To solve this, we need to set up a proportion.

We know 14 is a certain percent of 70, and we want to find what that percent is.

So, we set up the proportion 14/70 = x/100, where x is the percent, we are looking for.

Now we can cross-multiply to solve for x.

We get 14 x 100 = 70 x

x = [tex]\frac{1400}{70}[/tex]

So, x = 20.

Therefore, 14 is 20% of 70.

Determine the maximum value of the function ????(x) = (x − x 2 )/(1 + 8x 2 ) and the value of x at which this occurs.

Answers

The maximum value of the function f(x) = (x − x²)/(1 + 8x²) is 1/4, and it occurs when x = 1/2.

A function is a mathematical relationship between input and output values.

In this problem, we have a specific function defined as

=> f(x) = (x − x²)/(1 + 8x²).

Let's start by analyzing the expression of the function.

The function is composed of two parts:

=> (x − x²) and (1 + 8x²).

The first part is a simple polynomial expression with degree 2. It represents a parabolic shape with a vertex located at (1/2, 1/4).

The second part, (1 + 8x²), is always positive, so it does not affect the shape of the function.

The maximum value of the function will occur when the first part, (x − x²), is at its maximum. Since this part is a parabolic shape with a vertex at (1/2, 1/4), the maximum value is 1/4.

So, the maximum value of the function

=>  f(x) = (x − x2)/(1 + 8x²) is 1/4.

To find the value of x at which this occurs, we will have to find the x-coordinate of the vertex of the parabolic shape.

This can be done using the formula for the x-coordinate of the vertex of a parabolic equation, which is -b/2a.

Plugging in the values of a and b from the equation (x − x²) gives us

x = 1/2.

For the given triangles ΔABC ≈ ΔADE, the measurement  of angle ACB is, 87°

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

One triangle, ΔABC

one segment DE which is intersecting sides AB & AC

ΔABC has one similar triangle inside, which is ΔADE

Triangle ΔABC and ΔADE similar,

So, we can say ΔABC ≈ ΔADE

And it is known that

for similar triangles, ratio of corresponding angles of both the triangles are equal for similar triangles

so, ∠DAE/∠AED  = ∠CAB/∠ABC

⇒  62°/(11x -2)°  =  62°/(6x + 13)°

⇒  (11x -2)°  = (6x + 13)°

⇒   11x - 6x = 13 + 2

⇒    5x  = 15

⇒      x = 3

So,

∠ADE = 11x - 2 = 11 x 3 - 2 = 31°   =  ∠ABC

It is known that,

Sum of all the interior angles of triangle is 180°

Now,

∠ACB + ∠CAB + ∠ABC = 180°

∠ACB + 62° + 31°  = 180°

∠ACB  = 180° - 93°

           =  87°

Hence, the angle ACB is 87°

[tex]\left \{ {{3x^{2}+y^{2} =16} \atop {x^{2}-y^{2} =4}} \right.[/tex]

Answers

The solution to the system is:

(x, y) = (2.236, 1), (-2.236, 1), (2.236, -1), or (-2.236, -1).

This represents two equations hyperbola and ellipse which intersect at exactly 4 points.

The system of equations, as follows:

3x² + y² = 16

x² - y² = 4

We can solve this system of equations by substitution.

Starting with the first equation, we can isolate y²:

y² = 16 - 3x²

Substituting that into the second equation, we get:

x² - (16 - 3x²) = 4

Expanding the right side:

x² - 16 + 3x² = 4

4x² = 4 + 16

4x² = 20

Dividing both sides by 4:

x² = 5

Taking the square root of both sides:

x = ±√5 = ± 2.236

With x found, we can substitute it back into the expression for y²:

y² = 16 - 3x²

y² = 16 - 3(√5)²

y² = 16 - 3(5)

y² = 16 - 15

y² = 1

Taking the square root of both sides:

y = ±1

So the solution to the system is:

(x, y) = (2.236, 1), (-2.236, 1), (2.236, -1), or (-2.236, -1)

This means the two equations are hyperbola and ellipse which intersect at exactly 4 points.

and tet core mut be integer

Answers

Let P(t)=36(1−e^(−kt))+56 represent the expected core for a student who studied t hour for a test, suppose k=0. 24 so student scored 56% without studying.

If the student don't study then,

It corresponds to t= 0 .

We can evaluate the function with the t=0 so we can have

P(t) = 36(1−e^(−kt)) + 56

were k = 0.24

P(0) = 36 (1 - [tex]e^{0.24(t)}[/tex]) + 56

= 36 (1 - [tex]e^{0.24(0)}[/tex]) + 56

= 36 (1 - 1 ) + 56

=56%

Therefore, Let P(t)=36(1−e^(−kt))+56 represent the expected core for a student who studied t hour for a test is 56%.

The derivative of a function of a real variable in mathematics quantifies the sensitivity of the function's value (output value) to changes in its argument (input value). Calculus's core tool is the derivative. The velocity of an item, for instance, is the derivative of its position with respect to time; it quantifies how quickly the object's position varies as time passes.

He mixed together ⅔ cup cheddar, ⅚ cup mozzarella, and ¾ cup parmesan. How many cups of cheese does Albert have in his mixture altogether?
Albert then used ½ cup from the cheese mixture to make a pizza. How much cheese, in cups, does Albert have left?

Answers

Albert have left 7/4 cups of cheese left.

What is fraction?

Fractions in Math, represent a numerical value that expresses a part of a whole. The whole can be any number, a specific value, or a thing.

Given,

Amount of cheddar = 2/3 cup

Amount of mozzarella = 5/6 cup

Amount of parmesan = 3/4 cup

Total cups of cheese

= cheddar + mozzarella + parmesan

= 2/3 + 5/6 + 3/4

= 8 + 10 + 9 /12

= 27/12

= 9/4

He puts 1/2 cup of cheese in pizza

Cheese left = 9/4 - 1/2 = 9 - 2 / 4 = 7/4

A company i planning to purchae a plot of land for $200,000 to build a factory there are two option offered by a lending intitution

Answers

To choose the best option for the company, it is important to consider the total amount of interest that will be paid over the life of the loan.

With the 30-year loan, the total interest paid over the life of the loan will be higher than with the 15-year loan, because the interest rate is higher and the loan is paid over a longer period of time.

However, the shorter loan term means that the monthly payments are higher, which could be a financial burden for the company. Therefore, it is important to compare the total interest paid over the life of the loan for both options to determine which is the best option for the company.

Which function best models the data?

Answers

The function that best models the data table is; Option D: h(T) = -0.85t² + 1.63t + 1.51

How to find the function model?

A mathematical function model is defined as a mathematical description  by means of a function or an equation- of a real-world situation such as size of a population, demand for a product, speed of a falling object, life expectancy of a person at birth, or cost of emission reductions, etc.

From the table, we see that at time, t = 0 s, height(h) = 1.5 m.

Looking at the options, it means that options A and C cannot be correct.

Finally, at t = 1, h = 2.3. Plugging 1 for t in option D gives;

h(1) = -0.85(1²) + (1.63)1 + 1.51

= -0.85 + 3.12

= 2.27

This is approximately 2.3 and will be the correct option

(3) I'm stuck with my math help find me the x and the y show all ur steps ​

Answers

a) On solving the linear equations y = - 6x - 11  and y = 4x + 19, the solutions are x = -3 and  y = 7.

b) The system of equations has one solution.

c) The solution is obtained as x = -3 and y = 7.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The two linear equations given are -

y = - 6x - 11 .... (1)

y = 4x + 19 .... (2)

Substitute equation (1) in (2) -

- 6x - 11 = 4x + 19

Collect all the like terms -

- 6x - 4x = 19 + 11

-10x = 30

x = 30 / -10

x = -3

Substitute the value of x in equation (1) -

y = - 6(-3) - 11

y = 18 - 11

y = 7

The two equations form a linear graph and intersect at point (-3,7).

So, there is only one solution to the system of equations.

Therefore, the solutions are x = -3 and y = 7.

f(x) = (x + 5)(x -1)
how do i plot the values on a number line where it function is equal to zero

Answers

The zeros are x = -5 and x = 1, and the graph can be seen at the end.

For which values of x is the function equal to zero?

Here we have the quadratic function:

f(x) = (x + 5)*(x - 1)

The function is equal to zero when:

(x + 5)*(x - 1) = 0

And that happens if one of the two factors is zero, so:

x + 5 = 0  ----> x = -5

x - 1 = 0 -----> x= 1

So the function is equal to zero for x = -5 and x = 1, to graph them just graph the points (-5, 0) and (1, 0) on the coordinate axis.

What is meant by equational system?

A limited set of equations for which we looked for common solutions is known as an equation system. It is also known as an equation set or a collection of simultaneous equations. A group of equations can be categorized in the same way as a single equation.

You must learn more about how many calories each of your two machines burns per minute!

However, you can locate a few facts about your workout goals in this word problem to get things started. You can calculate the ratio of 300 calories in 40 minutes to get the number of calories you should aim for per hour or minute:

For an hour's worth of calories, 300 calories divided by 40 minutes is x calories (you are aiming for 450 calories burned per hour)

7.5 calories per minute, or 300 calories divided by 40 minutes, is another way to look at it.

One online variant of this issue completes the setup in this manner. [WARNING: It's possible that your issue from school is different. In that situation, just use this illustration:

Eight calories per minute for the first machine

6 calories per minute for the second machine

This enables us to construct an equational system. Calorie burn will be the first equation.

8x + 6y = 300

On the machine that burns 8 calories per minute, x represents the number of minutes, and y represents the number of minutes.

Simply put, a second equation demonstrates that the sum of the minutes is 40:

x + y = 40

You can now solve the system using substitution, elimination, or linear combinations. I'll modify the second equation using substitution:

x = 40 - y

Now substituting into the first equation:

8(40 - y) + 6y = 300

320 - 8y + 6y = 300

2y = 20

y = 10

Once you have determined what x is, you may calculate how many minutes would be spent on each machine.
