The value of year is 13 years (approx) after simple interest of 2800.

What is simple interest?

Simple Interest (S.I) is the method of calculating the interest amount for some principal amount of money.

Where,

Amount (A) is the total money paid back at the end of the time period for which it was borrowed.

Given, the principal amount = 17900

rate of interest = 13.25%

Amount = 2800

To find the time.

We know the relation between amount and principal value is given by

Amount = principal(1- rate/100)^t

2800 = 17900 (1- 13.25/100)^t

2800/17900= (0.8675)^t

0.156 = (0.8675)^t

taking log on the both side.

ln (0.156) = ln (0.8675)^t

ln(0.156) = t ln(0.8675)

ln(0.156)/ln (0.8675) = t

t = 13.26

t = 13 years approx.

The inverse of the function is y = ( 1/5 )x - 6.

An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Consider the function,

y = 5x + 30

To find the inverse of the function we interchange x and y then find the equation for y.

Therefore, after interchanging x and y:

x = 5y + 30

Subtracting 30 from each side of the equation.

x - 30 = 5y + 30 - 30

x - 30 = 5y

Now, dividing the whole equation by 5

( x - 30 ) / 5 = 5y / 5

y = ( 1/5 )x - 30/ 5

y = ( 1/5 )x - 6

Therefore, the inverse of the function y = 5x + 30 is y = ( 1/5 )x - 6.

The left right hand derivative is 3.

The left hand derivative is 2.

The function is not differentiable at x = 1.

When x < 1,

given that the function is, f(x) = 2x² - 2x - 1

Differentiating with respect to 'x' we get, f'(x) = 4x - 2

When x \(\geq\) 1,

given the function is, f(x) = 3x - 3

Differentiating with respect to 'x', f'(x) = 3

Now, left hand derivative,

f'(1 -) = (4x - 2) at 1 = 4*1 - 2 = 4 - 2 = 2

f'(1+) = 3

Since, left hand derivative and right hand derivative for given function at x =  1 is not equal, so the function is not differentiable at x = 1.

Answer:

1017in^3

Step-by-step explanation:

The probability that 3 of 8 stolen cars will be recovered is 0.296 or approximately 0.30.

The given problem involves a binomial distribution, where the probability of success (recovering a stolen car) is p = 0.78 and the number of trials is n = 8. We need to find the probability of getting exactly 3 successes.

The probability of getting exactly k successes in n trials can be calculated using the binomial probability formula:

P(k successes) = (n choose k) * \(p^k\) * \({1-p}^{n-k}\)

where (n choose k) represents the binomial coefficient, which can be calculated as:

(n choose k) = n! / (k! * (n-k)!)

where n! represents the factorial of n.

Using the above formula with k = 3, n = 8, and p = 0.78, we get:

P(3 successes) = (8 choose 3) * 0.78³ * (1-0.78)⁵

= 56 * 0.78³ * 0.22⁵

= 0.296

Answer:

Step-by-step explanation:

2 × 2 = 4

4 + 3 = 7

denominator stays the same so 7/2 is the answer

An odd number can be written as \(2n+1\) where n is an integer.

If \(2n+1\) is our first odd number, the next consecutive odd number will be 2 more than that. The third one will be 4 more.

If we only add 1, we'd get an even number, so we need to add 2.

First number:

\(2n+1\)

Second number (2 more than the first number):

\(2n+1+2=2n+3\)

Third number (4 more than the first number):

\(2n+1+4 = 2n+5\)

The sum is these 3 numbers added together. Let's do that now:

\((2n+1) + (2n+3) + (2n+5)\)

\(2n + 2n + 2n + 1 + 3 + 5\\6n + 9\)

The sum is, thus, \(6n+9\). We know this sum is equal to -27:

\(6n+9 = -27\)

Subtract 9 from both sides:

\(6n = -36\)

Divide both sides by 6:

\(n = -6\)

Now that we know n, we can find our 3 numbers.

For the first number, we can use its expression in section 2.

\(2n +1 = 2*(-6)+1 = -12+1 = -11\)

For the second number, we can just use the fact that it's 2 more than our first number, -11. If you're wondering why this is, review section 1.

\(-11 + 2 = -9\)

Same for our third number, it's 4 more than our first number or 2 more than our 2nd number:

\(-11 + 4 = -7\\or\\-9 + 2 = -7\)

Our three consecutive numbers are -11, -9, and -7. As we can see, the largest of these three is -7.

Prince George's County is situated in the east-central region of Maryland, United States of America. It's possible for Prince George's County to experience a tsunami or earthquake in light of what is known about tsunamis and earthquakes. Although it is improbable to have tsunamis and earthquakes in Prince George's County, they can still occur.

A tsunami is a huge wave that is triggered by seismic waves or underwater disturbances. It has the potential to cause significant damage, including death. Tsunamis have affected the east coast of the United States before. Nonetheless, these occurrences are rare and often occur on the West Coast.

An earthquake is a phenomenon that occurs when tectonic plates beneath the earth's surface shift or move. It may cause shaking, displacement, and even soil liquefaction, resulting in significant harm. Earthquakes are uncommon in Prince George's County, but they can occur.

A tsunami or earthquake is unlikely to occur in Prince George's County. However, as a result of climate change, we are seeing more extreme weather events. Climate change could raise the likelihood of tsunamis or earthquakes occurring in the future. Nevertheless, the probability of them occurring is still very low.

The correct dilation is Its sides are 2 times as long as those of the original square.

When a figure is dilated with a scale factor of 2, all of its dimensions are multiplied by 2.

This means that the new side length of the square will be twice the length of the original side.

Therefore, the image of the square after a dilation with a scale factor of 2 will have sides that are 2 times as long as those of the original square.

The value of the exponent of the base 10 for this product is -2.

Step-by-step explanation:

\(5.86\,\,10^{-7}\,\,*\,\,3.1\,\,10^4=18.166\,\,10^{-7+4}=18.166\,\,10^{-3}\)

Now, in order to represent this number in scientific notation, we need to reduce the coefficient 18.166 to a coefficient larger or equal to 1 and smaller strictly than 10, by using division or multiplications by powers of 10. In order to reduce it to 1.8166, we need to divide the original 18.166 by ten so we do the following in order not to change the given number (multiply and divide by ten at the same time):

\(\frac{18.166\,\,10}{10} \,10^{-3}=1.8166\,*\,10\,*\,10^{-3}=1.8166\,\,10^{-2}\)
