The rate at which the diameter decreases is  -0.16cm/min

Diameter:

In geometry, diameter refers the straight line that goes from one side to the other side of a circle, passing through the center.

Given,

Here we need to find if a snowball melts so that its surface area decreases at a rate of 1cm^2/min, find the rate at which the diameter decreases when the diameter is 10 cm. Finish solving the problem. Write an equation that relates the quantities.

Here  we obtained the equation that relates the surface area S and the diameter D of a sphere given by

=> S = πD²

Now, we have differentiate the equation as,

=> dS/dt = d/dt (πD²)

=> dS/dt = π d/dt (D²)

​=> dS/dt = 2πD dD/dt

Now, Solving for dD/dt, which is the unknown for this problem, we have

=> dD/dt ​= 1/2πD​ x dS​/dt

Now, substituting the given values, the rate of change of the diameter when D=10 cm and dS/dt as (-1) is

=> dD/dt = 1/2 x π x 10 (-1)

=> dD/dt = -1/20π

The facility's approximate cost of early turnover for this year is $45000.

The cost of turnover is the cost associated with turning over one position. This calculation includes the cost of hiring for that position, training the new employee, any severance or bonus packages, and managing the role when it is not filled. Every company will experience some turnover.

Turnover cost refers to expense both tangible or intangible associated with replacing an employee. It is extremely high: it's estimated that losing an employee can cost a company 1.5-2 times the employee's salary.

Shift A has number of associated leaving the facility within 90 days is 8, per associated cost is $3000 and total cost is $24000.

Shift B  has number of associated leaving the facility within 90 days is 5, per associated cost is $3000 and total cost is $15000.

Shift C  has number of associated leaving the facility within 90 days is 2, per associated cost is $3000 and total cost is $6000.

Shift D  has number of associated leaving the facility within 90 days is 0, per associated cost is $3000 and total cost is $30.

Therefore

Total cost = $24000 + $3000 + $6000

Total cost = $45000

Hence the facility's approximate cost of early turnover for this year is $45000.

If they keep running at the same pace, they will eventually meet at the same end of the course after 30 minutes.

The rate at which distance and time change is what is meant by speed. It has the aspect of temporal and spatial distance. The basic unit of distance with the basic unit of time are combined to form the SI unit of speed. This means that the SI unit of speed is the metre per second.

The way that the issue is described is vague.

I believe what is being said here is that they continue to jog at the same speed.

Half a mile per ten minutes is Diane's speed.

2/3 miles per 10 minutes is Jack's speed.

The numerator and denominator (top and bottom of the ratio) must be multiplied by the factor between 10 minutes and an hour (60 minutes) in order to convert this to a standard miles per hour format.

60/10 = 6.

In order to convert the above speeds to miles per hour, we must multiply both speeds by 6.

Diane: (1/3 divided by 6)/hour equals 2 miles/hour

Jack: (4 miles per hour) = (2/3 x 6) / hour

Diane will complete one length in the time it takes Jack to complete a round trip (back) because he runs twice as fast as she does.

Running a mile at a speed of two miles per hour takes Diane 30 minutes.

Running 2 miles (back and forth) at a speed of 4 miles per hour will take Jack 30 minutes.

So after 30 minutes they will meet again at his starting point.

Consequently, we deduce that the typical output voltage is under 130.

In statistics, the standard deviation measures how widely distributed or how much a bunch of values can vary. While a big standard deviation shows that values are scattered throughout a wider range, a low standard deviation suggests that values are frequently close to the set's mean.

Here,

A defined output voltage of 130 is offered for an electrical circuit.

The voltage for this circuit was measured 40 times independently, with a sample mean of 128.6 and a standard deviation of 2.1.

Let's say the average output voltage.

Null Hypothesis, [tex]H_{0}[/tex]:  = 130 denotes that the average output voltage is 130.

A Different Hypothesis, [tex]H_{A}[/tex] :  < 130  ( it indicates that the average output voltage is below 130.)

One-sample t test statistics will be employed in this case because we are unsure about the population standard deviation;

            T.S.  =   ~ [tex]\frac{X^{'}-u }{\frac{s}{\sqrt{n} } }[/tex]

In this case, sample mean output voltage equals 128.6

Sample standard deviation equals 2.1, or s.

n = 40 for the sample of independent readers.

Thus, test statistics equal.

So, test statistics  =    ~[tex]\frac{128.6-130 }{\frac{2.1}{\sqrt{40} } }[/tex]

                              =  -4.216

Now, for a left-tailed test with a 0.05 level of significance, the t table provides a critical value of -1.685 at 39 degrees of freedom. We have enough data to reject our null hypothesis because it will fall in the rejection region because our test statistics are smaller than the crucial value of t, which is -4.216 -1.685.

Consequently, we deduce that the typical output voltage is under 130.

We know very well that if a triangle is a right angled it means that  Pythagorean Theorem is applicable on it.

Pythagorean Theorem states that if a triangle is right angled then the sum of square of two sides which are originating from that angle which is 90 degree is equal to square of third side.

In other words,a²+b²=c² where a and b are two sides originating from 90 degree angle and c is the third side which is opposite of the 90 degree angle.

Now, we have a=14 and b=19cm,we need to find value of c.

What is function ?

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable).

An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.

Functions can be roughly categorized into four sorts. based on the element Numerous to one function, onto function, one to one and onto function, into function.

1.f(x) = 2x/3 - 17

Finding the inverse

y = f(x)

  = 2x / 3 - 17

Exchange the variables, x for y and y for x

x = 2y / 3 - 17

Isolate the variable y

Adds 17 both sides

x + 17 = 2y / 3

Multiply by 3 both sides

3(x+17) = 2y

Divide by 2 both sides

y = 3(x + 17)/2

let f^-1(x) = y

f^-1(x) = 3(x + 17)/2

2. f(x) = x - 10

Finding the inverse

y = f(x)

  = x - 10

Exchange the variables, x for y and y for x

x = y - 10

Isolate the variable y

Adds 10 both sides

y = x + 10
