This is a system of equations problem. Let x be the number of dimes and y be the number of nickels.

From the problem, we know the following:

x + y = n (where n is the total number of coins)

y = 3x - 9 (because the number of nickels is three times the number of dimes minus nine)

We also know that the total value of the coins is $2.55 and that a dime is worth $0.10 and a nickel is worth $0.05. So we can create an equation using the total value of the coins:

0.10x + 0.05y = 2.55

Now we have a system of three equations and three variables. To solve for x, y and n, we can use substitution or elimination method.

First equation and second equation:

x+3x-9 = n

4x-9=n

4x = n+9

x = (n+9)/4

By substituting the value of x in equation 3

0.10*(n+9)/4 + 0.05*(3*(n+9)/4-9) = 2.55

Solving this equation we get n = 63

Thus, x = (63+9)/4 = 18 dimes

y = 3x - 9 = 3*18 - 9 = 45 nickels

So, Carolyn has 18 dimes and 45 nickels.

The Polynomial 4 will be 3x^2 - 2. The solution is obtained using arithmetic operations.

What are arithmetic operations?

There are four basic operations which are listed as follows:

⇒Polynomial 1 = x^2 - x^2 + x + x + x + x - 1 + 1 - 1

⇒Polynomial 1 = 4x - 1

⇒Polynomial 2 = x + x + x - x - x^2 - x^2 - 1 + 1 - 1

⇒Polynomial 2 = 2x - 2x^2 - 1

⇒Polynomial 2 = -2x^2 + 2x  - 1

⇒Polynomial 3 = 1 + 1 + 1 + 1 - x - x + x - x^2 + x^2 - x^2

⇒Polynomial 3 = 4 - x - x^2

⇒Polynomial 3 = -x^2 - x + 4

We are given sum of all four expressions = 5x

So,

4x - 1 + (-2x^2 + 2x  - 1) + (-x^2 - x + 4) + Polynomial 4 = 5x

On simplifying the equation,

⇒4x - 1 - 2x^2 + 2x  - 1 - x^2 - x + 4 + Polynomial 4 = 5x

⇒5x - 3x^2 + 2 + Polynomial 4 = 5x

⇒Polynomial 4 = 5x - (5x - 3x^2 + 2)

⇒Polynomial 4 = 5x - 5x + 3x^2 - 2

⇒Polynomial 4 = 3x^2 - 2

Hence, polynomial 4 is 3x^2 - 2 which will be 3 big black squares and 2 small white squares.

Let's use v1(t) and v2(t) to represent the speed of the first and second runners, respectively, at time t. The functions v1 and v2 must both be continuous in the time variable t, hence this assumption must be made.

So, their difference, a(t), is similarly a continuous function in the variable t, with the formula a(t) = v1(t)-v2(t).  

Now, using the principle of contradiction, one may demonstrate that t1, t2, such that a(t1) is less than or equal to 0 and a(t2) is higher than or equal to 0, exist because the overall average speed of both runners is identical.

Now, we may utilize the continuous function a's Intermediate Value Property to locate a t0 between t1 and t2, where a(to)=0 and the runners are moving at the same speed at this point.

The angular size of the minor arc AB can be calculated using the formula: Angular size = Arc length/Radius. To calculate the angular size of the minor arc AB, we need to know the length of the chord AB and the radius of the circle. In this case, the chord AB is 16 cm long and the radius of the circle is 12 cm. Therefore, we can calculate the angular size of the minor arc AB by dividing the length of the chord AB by the radius of the circle, which is 16 cm/12 cm = 1.333 radians.

c) 12 years: The value of the investment after 12 years would be $2712.20.

a) 2 years: Value = 2000 x e^(0.045 x 2) = $2090.45

b) 4 years: Value = 2000 x e^(0.045 x 4) = $2186.63

c) 12 years: Value = 2000 x e^(0.045 x 12) = $2712.20

The value of a continuously compounded interest rate can be calculated using the formula: Value = P x e^(r x t), where P is the principal amount, r is the interest rate per year, and t is the time in years.

Using this formula, the value of a $2000 investment with an interest rate of 4.5% after 2 years would be $2090.45. This can be calculated by plugging the values into the formula: Value = 2000 x e^(0.045 x 2) = $2090.45.

The value of the same investment after 4 years would be $2186.63, which can be calculated in the same way: Value = 2000 x e^(0.045 x 4) = $2186.63.

The value of the same investment after 12 years would be $2712.20, which can be calculated by plugging the values into the formula: Value = 2000 x e^(0.045 x 12) = $2712.20.

The total amount of money that Edison spends on salad and pizza is equal to e.

e = s * $2 + p * $3

This equation can be used to calculate the amount of money Edison spends on salad and pizza. The first part of this equation, s * $2, calculates the cost of the bowls of salad. The cost of one bowl of salad is $2, and the number of bowls of salad that Edison buys is represented by s.

The second part of this equation, p * $3, calculates the cost of the slices of pizza. The cost of one slice of pizza is $3 and the number of slices of pizza that Edison buys is represented by p.

When added together, the total amount of money that Edison spends on salad and pizza is equal to e. For example, if Edison buys four bowls of salad (s=4) and six slices of pizza (p=6), the total amount of money he spends (e) is equal to (4 * $2) + (6 * $3) = $24.

The graph of the function is a line with a slope of 1.5 and a y-intercept of 2.5. This can be seen by considering the equation c(n) = 1.5n + 2.5. As the number of new players n increases, the cost c increases by 1.5 for each new player added. For example, if you add 3 new players, the total cost c is 1.5(3) + 2.5 = 6.5. Similarly, if you add 5 new players, the total cost is 1.5(5) + 2.5 = 8.5.

For example, if you want to add 10 new players, the cost will be $c=1.50\times10+2.50=17.50$. Substituting $n=10$ into the function gives $c=17.50$. The graph of this function is a straight line that passes through the origin and has a positive slope of 1.50.

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be represented as P ( 2 , -1 )

Let the second point be represented as Q ( 1 , 2 )

Now , the slope of the line between the points is

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

The percentage of the variation in height that is explained by a regression on age is 0.64, which is the right answer.

from the aforementioned case, The relationship between children's age and height is strongly correlated, as evidenced by the correlation coefficient R of 0.8. Given the correlation coefficient value, we can calculate the coefficient of determination (R2), which indicates the proportion of variation that the regression model can account for.

Therefore, R2 = 0.82 = 0.64, which is the coefficient of determination. Therefore, the proportion of the variation in children's height that can be attributed to age is 0.64 and the remaining 0.36 can be attributed to other factors.
