The number of possibilities for 8 of 37 servers to fail is 38608020

From the question, we have

Total number of servers, n = 37

Numbers to servers that fail, r = 8

The number of ways for 8 serves to fail is calculated using the following combination formula

Total = ⁿCᵣ

Where

n = 37 and r = 8

Substitute the known values in the above equation

Total = ³⁷C₈

Apply the combination formula

ⁿCᵣ = n!/(n - r)!r!

So, we have

Total = 37!/29!8!

Evaluate

Total = 38608020

Hence, the number of ways is 38608020

The year in which Gert will find that she has doubled her money is year 20.

Simple interest is when the interest earned on an investment increases linearly each year.

The formula that can be used to determine simple interest is:

Simple interest = amount invested x duration of the investment x interest rate.

When the amount of money in the account is double what it is now, it means that the interest earned would be $2000 and the value of the account would $4000 (2000 + 2000).

Year when investment would have doubled  = simple interest / (amount invested x interest rate)

Year when investment would have doubled  = $2000 / (0.05 x 2000)

Year when investment would have doubled  = $2000 / 100 = 20 years

We know that a function has a discontinuity if the left hand limit and right hand limit of the function are there but they are not equal.

According to the question,

We have the following information:

A function is given and we need to find if the given function is discontinuous or not.

There are two situations to find this whether the function is discontinuous or not. First, we need to know that the function has both the left hand limit as well as the right hand limit.

Second condition is to check whether if the limits are equal or not. If they are not equal then the function is discontinuous.

Hence, we know that a function has a discontinuity if the left hand limit and right hand limit of the function are there but they are not equal.

All Sides are equal.

Diagonals bisect at 90°.

In our question,

AB = DC is given for a quadrilateral ABCD (parallelogram).

When a parallelogram's sides are uneven, symmetry is disrupted and its diagonals do not bisect at 90 degrees. However, when all of the sides are equal, the diagonal does bisect at 90 degrees and the parallelogram becomes a rhombus.

Therefore, when all of a parallelogram's sides are equal, it becomes a rhombus.

The motion of the dolphin, evaluated using the kinematic equations and Newton's second law of motion are;

Mathematically, Newton's second law of motion states that force is the product of mass and acceleration.

The mass of the dolphin = 230 kg

Height to which the dolphin leaps = 6.4 m

The distance the drag brings the dolphin to a stop = 6.4 meters

First part;

The time it takes the dolphin to stop can be found from the equation;

At the water surface;

m·g·h = 0.5·m·v² (conservation of energy)

g·h = 0.5·v²

v² = 2·g·h

Therefore;

v² = 2 × 9.81 × 6.4 = 125.568

In the water, the initial velocity is v, the velocity at 1.5 meters depth is u, we get;

u² = v² - 2·a·s

Therefore;

v² = 2·a·s

a = v²/(2·s)

a = 125.568/(2 × 1.5) = 41.856

a = 41.856 m/s²

v = u - a·t

t = (u - v)/a

Therefore;

t = (√(125.568))/41.856 ≈ 0.268

The time it takes the dolphin to stop is about 0.268 seconds

Second part

Newton's second law of motion states that force is directly proportional to the rate of change of momentum produced

Mathematically

Force = Mass × Acceleration

Force on the dolphin, F = 230 kg × 41.856 m/s²= 9626.88 N

The number of minutes for 20 bacteria be left is 439minutes. The decay constant is 0.0081

An exponential function is a mathematical function, which is used in many real-world situations. It is mainly used to find the exponential decay or exponential growth or to compute investments, model populations and so on.

The No of bacteria left at a particular time t is given as N(t)= Noe^-kt

where No= initial number of bacteria

k= decay constant and t = time

after 13 minutes

630= 700e^-13k

divide both sides by 700

630/700= e^-13k

0.9= e^-13k

ln0.9= -13k

k= ln0.9/-13 = -0.1054/-13 = 0.0081

time for 20 bacteria to be left =

20= 700e^-0.0081t

= 20/700=e^-0.0081t

0.0286= e^-0.0081t

ln0.0286= -0.0081t

-3.554= -0.0081t

Answer:

x=7

Step-by-step explanation:

3(2x-5)=9(10-x)

6x-15=90-9×

6x+9x=90+15

15x=105

×=7

Answer:

x = 7

Step-by-step explanation:

1. Distribute

3(2x - 5) = 9(10 - x)

6x - 15 = 9(10 - x)

2. Rearrange Terms

6x - 15 = 9(10 - x)

6x - 15 = 9(-x + 10)

3. Distribute

6x - 15 = 9(-x + 10)

6x - 15 = -9x + 90

4. Add 15 to both sides

6x - 15 = -9x + 90

6x - 15 + 15 = -9x  + 90 + 15

5. Simplify

Add the numbers:

6x - 15 + 15 = -9x + 90 + 15

6x = -9x + 90 + 15

Add the numbers:

6x = -9x + 90 + 15

6x = -9x + 105

6. Add 9x to both sides

6x = -9x + 105

6x + 9x = -9x + 105 + 9x

7. Simplify

Combine like terms:

6x + 9x = -9x + 105 + 9x

15x = -9x + 105 + 9x

Combine like terms:

15x = -9x + 105 + 9x

15x = 105

8. Divide both sides by the same factor

15x = 105

15x/15 = 105/15

9. Simplify

Cancel terms that are in both the numerator and denominator:

15x/15 = 105/15

x = 105/15

Divide the numbers:

x = 105/15

x = 7

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In ΔSTU, s = 250 inches, ∠U=17° and ∠S=52°.

Now,

Since, In ΔSTU, s = 250 inches, ∠U=17° and ∠S=52°.

Hence, ∠ T = 180 - (17 + 52)

∠ T = 180 - 69

∠ T = 111°

Now, We use the sin rule as;

⇒ t / sint = s / sin s

⇒ t / sin 111° = 250 / sin 52

⇒ t = sin 111° × 250 / sin 52

⇒ t = 0.93 × 250 / 0.79

⇒ t = 294.30 inches.

The difference between their average hiking rates is 0.51 miles/hour.

Given that, it took Lannie 1.9 hours to hike Ranger Cove Trail. It took Ava 4 hours to hike Mohawk Trail.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Using speed =Distance/Time

Here, Ranger Cove distance =4.8 miles and time =1.9 hours

Now, rate =4.2/1.9

= 2.21 miles/hour

Mohawk Trail distance =6.8 miles and time =4 hours

Now, rate =6.8/4

= 1.7 miles/hour

The difference between their average hiking rates
