a satellite in a circular orbit 1250 kilometers above earth makes one complete revolution every 110 minutes. find its linear speed, round your answer to 2 decimal places. assume that earth is a sphere of radius 6400 kilometers.

Answers

Its linear speed would be 1637.75  miles/hour

Vt =  435,49 Km/min

Vt  =  26129 Km/hour

Vt = 16630, 35  miles/hour

The distance from the earth center up to the satellite position is:

Earth radius  + distance above the earth  

radius of satellite  6400 + 1250   =  7650 Km

linear speed = Vt  = 2π*r/T

where

r is the radius of the satellite and T period  =  110 min

Then

Vt  =  6,28* 7650 / 110

Vt = 4804/110

Vt  =  43,674.54 Km/min

To get it in Km/h we must multiply by 60

Vt  =  26204m/hour

Answers

We can expect to find 185 defective fuses each day.

The correct answer is c) 185.

At first we have to find the expected number of defective fuses each day, we can use the formula for the expected value of a binomial distribution:

Expected Value (μ) = n * p

where:

n = number of trials (in this case, the number of fuses produced each day) = 500

p = probability of success (in this case, the probability that a fuse is defective) = 37/100 = 0.37

Expected Value (μ) = 500 * 0.37 = 185

So, we can expect to find 185 defective fuses each day.

The correct answer is c) 185.

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells xx shirts can be found using the function f(x) = 6x - 70. Find and interpret the given function values and determine an appropriate domain for the function.

Answers

The numeric values of the function are given as follows:

f(-2) = -82, meaning that if the company sells -2 shirts, it would have a profit of -82 dollars. This interpretation does not make sense in the context of the problem.f(12) = 2, meaning that if the company sells 12 shirts, it would have a profit of 2 dollars. This interpretation makes sense in the context of the problem.f(17.5) = 35, meaning that if the company sells 17.5 shirts, it would have a profit of 36 dollars. This interpretation does not make sense in the context of the problem.

An appropriate domain for the situation is of:

{x ∈ N | x ≥ 0.}

What are the numeric values of the function?

The function in this problem is defined as follows:

f(x) = 6x - 70.

In which the variables are given as follows:

x is the number of shirts sold.f(x) is the profit when x shirts are sold.

Hence when x = -2, the numeric value is given as follows:

f(-2) = 6(-2) - 70 = -82.

This point is outside of the domain, as the number of shirts cannot be negative, hence an appropriate domain for the function is of:

{x ∈ N | x ≥ 0.}

As the number of shirts is also a countable amount.

When x = 12, the numeric value is given as follows:

f(12) = 6(12) - 70 = 72 - 70 = 2.

When x = 17.5, the numeric value is given as follows:

f(17.5) = 6(17.5) - 70 = 35.

a rectangular prism with dimensions of (x-3),(x-1), and (x-8) has a volume of 33x cubic units. what are the dimensions of the prism?

Answers

The dimensions of the rectangular prism with the volume 33x cubic units are 11units, 9units, 4 units.

As given in the question,

Dimension of the rectangular prism in form of x are :

( x - 3 ) , ( x - 1 ) , and ( x - 8 )

Volume of the rectangular prism = 33x cubic units

⇒ ( x - 3 )( x - 1 )( x - 8 ) = 33x

⇒ ( x² -4x + 3 )( x - 8) = 33x

⇒ x³ -12x² + 35x -24 = 33x

⇒  x³ -12x² + 2x -24 = 0

⇒ x² ( x - 12 ) + 2 ( x - 12 ) = 0

⇒ ( x - 12 )( x² + 2 ) = 0

⇒ x = 12 or x = √ -2

Dimensions cannot be square root of negative.

⇒ x = 12

x - 3 = 9 units

x -1 = 11 units

x - 8 = 4 units

Therefore, the dimensions of the rectangular prism are 9 units, 11unitsm and 4 units.

on a certain transatlantic crossing, 20 percent of a ship's passengers held round-trip tickets and also took their cars aboard the ship. if 60 percent of the passengers with round-trip tickets did not take their cars aboard the ship, what percent of the ship's passengers held round-trip tickets?

Answers

The percent of the ship's passengers held round-trip tickets is 50/100 = 50%.

Since the number of passengers on the ship is immaterial, let the number of passengers on the ship be 100 for convenience.  

Let x be the number of passengers that held round-trip tickets.  

Then, since 20 percent of the passengers held a round-trip ticket and took their cars aboard the ship, 0.20(100) = 20 passengers held round-trip tickets and took their cars aboard the ship.  

The remaining passengers with round-trip tickets did not take their cars aboard, and they represent 0.6x (that is, 60 percent of the passengers with round-trip tickets).  

Thus, 0.6x + 20 = x, from which it follows that 20 = 0.4x, and so x = 50.  

The percent of passengers with round-trip tickets is, then, 50/100 = 50%

A roundtrip flight is a flight itinerary that includes one flight to a vacation spot and some other flight lower back from that destination, which include flying from NYC to Paris after which Paris lowers back to NYC.

Answers

The smallest possible value of c is 1 in this case.

If the integer a, b and c are in arithmetic progression.

Then we can write,

b = (a+c)/2

If the integer a, b and c are in geometric progression,

Then, we can write,

b = √(ac)

Now, we can write,

a+b = 2√(ac)

Squaring both sides,

a²+c²+2ac = 4ac

(a-c)² = 0

So,

a = c.

If a = c.

Then,

b = (a+a)/2

b = a

So, a = b = c.

For this graph, determine whether x and y are proportional.
If x and y are proportional, fill in the blank with a number in simplest form.

Answers

Answer:

Proportional

y is 0.4 times x

or

y is 2/5 times x

Both numbers are the same, I don't know which form the computer expects you to enter

Step-by-step explanation:

x and y are proportional since there is a linear relationship between y and x.

Let's verify this

When x = 5, y = 2. So y/x = 2/5 = 0.4
So y = 0.4x  


When x = 10, y = 4
So y/x = 4/10 = 2/5 = 0.4

Again y = 0.4x

So the answer is 0.4, same as 2/5

Answer:

Step-by-step explanation:

the x and y are proportional because the number increases by the same number each time. so y =2 and x=5 then on the next one, if it's proportional, y will = 4 and x will = 10. another way you can be sure that it is proportional is that every time you add the first number you can divide it and get the first number. for example if you divide 4 by 2 you will get 2. if you divide 10 by 2 you get 10. so in a short answer yes it is proportional

suppose a sample of bone fossil contains 5.2% of the carbon-14 found in an equal amount of carbon in present-day bone. estimate the age of the fossil, assuming an exponential decay model. the half-life of carbon-14 is approximately 5700 years.

Answers

The age of the fossil is 24, 312 years assuming an exponential decay model.

Exponential decay model refers to model in which the amount of something decreases at a rate proportional to the amount left and this rate is given by a constant ratio k. The formula for remaining quantities of a substance is given by:

P = 100 e^(-kt)

Where P is the remaining quantity, k is the constant of decay, and t is time.

As the half life of the carbon 14 is 5700, when 50% of the substance remains,

50 = 100 e^(-5700k)

1/2 = e^(-5700k)

In(1/2) = In(e^(-5700k))

- In (2) = -5700k

k = In(2)/5700 = 0.0001216

Since, 5.2% carbon-14 remains,

5.2 = 100 e^(-0.0001216t)

0.052 = e^(-0.0001216t)

In(0.0052) = - 0.0001216

t = In(0.052) * - 0.0001216

Answers

To find out how many weeks it will take for John and Sarah to save the same amount of money, we must set their respective functions equal to each other and solve for x.

J = S

28 + 4x = x2 + 2x + 20

x2 + 2x - 4x - 8 = 0

x2 - 2x - 8 = 0

(x - 4)(x + 2) = 0

x = 4 or x = -2

Since x must be a positive value, the answer is that it will take John and Sarah 4 weeks to have the same amount of money saved.

We know that a right angle triangle is one in which one of the angles of the triangle is 90 degrees. If we know that one of the angles of the triangle has been given as 90 degrees, it then follows that the other two angles would have to be complementary.

Let us remind ourselves here and now that the angles that we say that they are complementary are the angles that do add up to about an angle of ninety degrees.

Having said this, we can see that the third angle is the angle A measures 90 degrees and angle B measures 50 degrees, it then follows that the third angle must have to measure 40 degrees. This would now give the correct balance of all the angles in the triangle.

The rank of population size from fastest to slowest growth is N = 1250, N = 1500, N = 1000, N = 750, N = 500, and N = 250.

The population growth rate is the measure that helps to determine how much the population size changes over time. The population growth rate shows either logistic growth or exponential growth. The formula for logistic population growth is given by [tex]\frac{dN}{dt}=r_{\text{max}}N\left(\frac{K-N}{N}\right)[/tex]. Here, N is the population size, t is time, r (max) is the maximum rate of increase, and K is the carrying capacity.

The one that grows fast will have a large population size, and the one that grows slowly will have a small population size. To rank the population size, arrange the given population size from the largest to the smallest. As a result, we get,
