The amount of money in the account after adding simple interest of 7% rate  is respectively $17.5, $52.5,  $122.5,  $350

Simple interest is a amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider principle amount(P), rate(R) and time(T).

Every time we calculate simple interest the principle values will be same unlike compound interest.

Formula;    Simple Interest(I) =  P × R × T/100

Given that,

P = $250

R =  7%

For T =  1 year

I  =   250 × 7 × 1/100

  =   $17.5

For T =  3 year

I  =   250 × 7 × 3/100

  =   $52.5

For T =  7 year

I  =   250 × 7 × 7/100

  =   $122.5

For T =  20 year

I  =   250 × 7 × 20/100

  =   $350

The gravitational potential energy of the vacationers will decrease as they approach the end of the pier.

As the vacationers approach the end of the pier, their gravitational potential energy will decrease.

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It depends on the height of the object and the acceleration due to gravity.

In this scenario, as the vacationers walk out on the horizontal pier, their height above the ground remains constant. Since the height does not change, the gravitational potential energy also remains constant.

However, as they approach the end of the pier, their distance from the center of the Earth decreases. As a result, the gravitational potential energy decreases because it is directly proportional to the distance from the center of the Earth.

To show that every amount greater than 17 dollars can be made from a combination of 3-dollar and 10-dollar bills, we can use a technique called "proof by induction."

First, let's check the base case: can we make 18 dollars using only 3-dollar and 10-dollar bills? Yes, we can use two 3-dollar bills and one 10-dollar bill: 3 + 3 + 10 = 16.

Now, let's assume that we can make any amount greater than n dollars using only 3-dollar and 10-dollar bills. We want to prove that we can make any amount greater than n+1 dollars as well.

To do this, we can consider two cases:

1. The amount we want to make includes at least one 10-dollar bill. In this case, we can subtract 10 dollars from the amount and use our induction hypothesis to make the remaining amount using only 3-dollar and 10-dollar bills. Then we add the 10-dollar bill back in, and we have made the original amount.

2. The amount we want to make does not include any 10-dollar bills. In this case, we can use our induction hypothesis to make the amount n-7 using only 3-dollar and 10-dollar bills (since 10 - 3 = 7). Then we add a 10-dollar bill and a 3-dollar bill to get n+3, and we can add another 3-dollar bill to get n+6. Finally, we add one more 3-dollar bill to get n+9, which is greater than n+1.

Therefore, we have shown that any amount greater than 17 dollars can be made from a combination of 3-dollar and 10-dollar bills using proof by induction.

Domain is all real numbers, and range is all numbers greater than or equal to -2.  If thee was anything you didn't understand let me know.  

Step-by-step explanation:

The domain is what x values work, or it may be better to say the horizontal axis.  is there any number you cannot use?  if you cannot tell, this is a parabola, like x^2.  Is there any number you cannot plug into x^2.  The answer is no, the domain for all parabolic functions is all real numbers.

The range you really want to look at visually here.  Range is y values you can get, or values on the vertical axis.  I would also compare it to x^2 again.  You should know you can make it as high as you want, here is the same.  but at -2, there is no point below that.  so the range is -2 and up

The total cost of the camera after including the sales tax in the cost of camera is found to be $819.1285.

The final price can be calculated once we figure out the value of 6.5% of $761.98. Solving this quandary is our first task.

Now, this result would be added back to the original price.

By first converting 6.5% to a decimal, which becomes 0.065, adding one to that, which equals 1.065, then multiplying by the camera's price, which is $761.98, we can accomplish it in a single step. 761.98 x 1.075 = 819.1285.

The total cost of the laptop is $819.1285, rounded up to two decimal places as we are dealing with money.

The constant of integration C1 was found by using the initial condition X'(0) = (-3/8), and the constant C2 was found by using the initial condition X(0) = (0) - (5).

To solve the given initial-value problem, we start by rearranging the equation:
3 11 16 × -(: * *:)* X' = 1 1 3
-(: * *:)* X' = (1/16)  (1/11)  (1/3)
Integrating both sides with respect to t:
-(: * *:)* X = (1/16) t + C1, where C1 is the constant of integration.
Multiplying both sides by the inverse of the matrix -(: * *:) gives:
X = (-1/8) t + C1/8 + C2, where C2 is another constant of integration.
To find the values of C1 and C2, we use the initial condition X(0) = (0) - (5):
X(0) = (-1/8) (0) + C1/8 + C2 = -5
C1/8 + C2 = -5
Since X'(t) = (-3/8), we have X'(0) = (-3/8). Using the equation X'(t) = (-3/8) and the initial condition X(0) = (0) - (5), we can solve for C1:
X'(t) = (-1/8) => (-3/8) = (-1/8) + C1/8 => C1 = -2
Substituting C1 = -2 into C1/8 + C2 = -5 gives:
(-2)/8 + C2 = -5 => C2 = -39/8
Therefore, the solution to the initial-value problem is:
X = (-1/8) t - 1/4 - (39/8)

The solution to the given initial-value problem is X = (-1/8) t - 1/4 - (39/8). The constant of integration C1 was found by using the initial condition X'(0) = (-3/8), and the constant C2 was found by using the initial condition X(0) = (0) - (5).

Answer:

Dude dont spend 100 points! This place is scamming people

Step-by-step explanation:

The range of the function N(t) = 3.75t + 20.25 is **[20.25, ∞)**, where 20.25 represents the minimum value (corresponding to the initial cost) and ∞ represents the unlimited maximum value as t approaches infinity.

The range of the function N(t) = 3.75t + 20.25, in the context of the problem, represents the possible values for the total cost (N) after a certain number of months (t).

The function N(t) = 3.75t + 20.25 is a linear equation, where t represents the number of months and 3.75t represents the monthly membership fee, while 20.25 represents the initial fee. By plugging in different values of t into the equation, we can determine the corresponding values of N(t) and establish its range.

To find the range, we need to consider the minimum and maximum values of N(t). Since the monthly membership fee of $3.75 will increase linearly with each month, the minimum value of N(t) occurs when t = 0 (representing the initial membership purchase). Plugging in t = 0 into the equation, we get:

N(0) = 3.75(0) + 20.25 = 20.25

Hence, the minimum value of N(t) is $20.25, which represents the total cost at the start of the membership.

To determine the maximum value of N(t), we need to consider an arbitrary large value of t. As t increases, the monthly membership fee contributes more significantly to the total cost. However, there is no upper limit mentioned in the problem, so we can assume that t can be any positive real number. Consequently, there is no specific maximum value for N(t), and it can increase indefinitely.

In summary, the range of the function N(t) = 3.75t + 20.25 is **[20.25, ∞)**, where 20.25 represents the minimum value (corresponding to the initial cost) and ∞ represents the unlimited maximum value as t approaches infinity.

Answer:

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

To find the probability of picking one red candle followed by another red candle without replacement, we need to consider the total number of possible outcomes and the number of favorable outcomes. So the probability of picking one red candle followed by another red candle without replacement is 1/6.

First, let's determine the total number of possible outcomes. Alfred draws one candle from the pack, leaving 3 candles. Then, he draws another candle from the remaining 3 candles. The total number of possible outcomes is the product of the number of choices at each step, which is 4 choices for the first draw and 3 choices for the second draw, resulting in a total of 4 * 3 = 12 possible outcomes. Next, let's determine the number of favorable outcomes. To have a favorable outcome, Alfred needs to draw a red candle on both draws. Since there are 2 red candles in the pack, the number of favorable outcomes is 2 * 1 = 2.Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes. Therefore, the probability of picking one red candle followed by another red candle is 2/12 = 1/6.Equation used: Probability = Number of favorable outcomes / Total number of possible outcomes.

In conclusion, the probability of picking one red candle followed by another red candle without replacement is 1/6.
