The expression (3x + 9)/(x + 3) simplifies to x + 3 for x ≠ -3.

To simplify the expression (3x + 9)/(x + 3), we can divide both the numerator and denominator by their greatest common factor (GCF), which is 3. This simplification is valid as long as x ≠ -3 to avoid division by zero.

Dividing the numerator 3x + 9 by 3 yields (3x + 9)/3, which simplifies to x + 3. Similarly, dividing the denominator x + 3 by 3 gives (x + 3)/3, which also simplifies to x + 3.

Therefore, the expression (3x + 9)/(x + 3) simplifies to x + 3 for x ≠ -3. This means that for any value of x except -3, the expression can be simplified to the simplified form x + 3.

To determine a reasonable range for the function h(t) = -16t^2 + 48t + 36, we need to consider the physical context of the problem.

Since the function represents the height of a ball thrown into the air, the range of the function should be the set of all possible heights that the ball can reach. In this case, the ball is thrown upward and then falls back down due to gravity.

The vertex of the parabolic function can give us some insights. The vertex of the parabola h(t) = -16t^2 + 48t + 36 occurs at the value of t = -b/2a = -48 / (2 * -16) = 1.5 seconds. Plugging this value into the function, we find h(1.5) = 54 feet.

Therefore, a reasonable range for the function is all heights from 0 feet up to a maximum height of 54 feet. In interval notation, the range can be expressed as [0, 54].

Step-by-step explanation:

The second derivative of y with respect to x is 0 in terms of t.

To find the second derivative of y with respect to x, we need to use the chain rule and differentiate both x and y with respect to t, and then divide dy/dt by dx/dt.

First, we need to find dx/dt and dy/dt:
dx/dt = d/dt(e^-3t) = -3e^-3t
dy/dt = d/dt(e^3t) = 3e^3t

Now, we can find dy/dx:
dy/dx = (dy/dt)/(dx/dt) = (3e^3t)/(-3e^-3t) = -e^6t

Finally, we can find the second derivative of y with respect to x:
d^2y/dx^2 = d/dx(dy/dx) = d/dx(-e^6t) = 0

Therefore, the second derivative of y with respect to x is 0 in terms of t.

In the initial list, there were 4 integers.

We have the following system if the mean is m, x is the list's initial sum, and n is the number of integers in the list:

m = x/n , m + 2 = (x + 15) / (n + 1) and m + 1 = (x + 16) / (n + 2).

The initial equation is x = mn.

Therefore, changing x in the other two equations:

m + 2 = (mn + 15) / (n + 1) ..............(1)

m + 1 = (mn + 16) / (n + 2)...............(2)

Based on equation (1):

(m + 2)(n + 1) =  mn + 15

mn + m + 2n + 2 = mn + 15

m + 2n + 2  = 15

m + 2n = 13

m = 13 - 2n.

Now change m in equation (2) to:

13 - 2n + 1 = ( n(13 - 2n) + 16) / (n + 2)

14 - 2n = (13n - 2n^2 + 16) / (n + 2)   Through-multiplication by n + 2:

(14 - 2n)(n + 2) =  13n - 2n^2 + 16

14n + 28 - 2n^2 - 4n =  13n - 2n^2 + 16

10n + 28 = 13n + 16

12 = 3n

n = 4.

Hence, there were 4 integers in the original list.

Answer:

15.7

Step-by-step explanation:

5 * 3.14 = 15.7

Answer:

Below

Step-by-step explanation:

CIRCUMFERENCE of a CIRCLE is given by  :  pi * d

  Circumference = pi * 5 in = 15.7 inches   (Don't forget UNITS !!)

Sofia has 17 nickels and 8 dimes in her pocket, for a total of $1.65.

To solve this problem, let's assign variables to represent the number of nickels and dimes Sofia has. Let's say N represents the number of nickels and D represents the number of dimes.
From the problem, we know that Sofia has a total of 25 coins. Therefore, we can write the equation: N + D = 25.
We also know that the total value of all the coins is $1.65. Since a nickel is worth $0.05 and a dime is worth $0.10, we can write the equation: 0.05N + 0.10D = 1.65.
To solve this system of equations, we can use substitution or elimination. Let's use substitution. We can solve the first equation for N: N = 25 - D.
Now, substitute the value of N in the second equation: 0.05(25 - D) + 0.10D = 1.65.
Simplify the equation: 1.25 - 0.05D + 0.10D = 1.65.
Combine like terms: 0.05D = 1.65 - 1.25.
Simplify the right side: 0.05D = 0.40.
Divide both sides by 0.05: D = 0.40 / 0.05.
D = 8.
Now, substitute the value of D back into the first equation to find N: N + 8 = 25.
Simplify the equation: N = 25 - 8.
N = 17.
Therefore, Sofia has 17 nickels and 8 dimes.

Step-by-step explanation:

You want to know the conversion factors that would be used to convert grams per day to kilograms per week.

A conversion factor is often expressed as a ratio that has its numerator equal to its denominator, but expressed with different units. The units of a conversion factor are generally chosen to be useful for the purpose of converting units you have to units you want.

Here, we have mass units of grams, and we want mass units of kilograms. We know that ...

  1000 g = 1 kg

so a suitable conversion factor is ...

  (1 kg)/(1000 g)

The units we have (g) are put in the denominator, so that multiplying by this factor will cancel units of grams, leaving units of kilograms.

We have time units of days, and we want time units of weeks. The time units are in the denominator of the original value (g/day). We know that ...

  7 day = 1 wk

so a suitable conversion factor is ...

  (7 day)/(1 wk)

The time unit of day in the numerator will cancel the time unit of day in the original value, leaving time units of weeks in the denominator.

\(1\dfrac{\text{g}}{\text{day}}=1\dfrac{\text{g}}{\text{day}}\cdot\boxed{\dfrac{1\text{ kg}}{1000\text{ g}}\cdot\dfrac{7\text{ day}}{1\text{ wk}}}=\dfrac{7\text{ kg}}{1000\text{ wk}}=0.007\text{ kg/wk}\)

Answer:

4(9 + 4)

Step-by-step explanation:

36 + 16 ← factor out HCF of 4 from each term

= (4 × 9) + (4 × 4)

= 4(9 + 4)

another way to write 36 + 16 is 4(9) + 4(4).

To rewrite the expression 36 + 16 using the distributive property, we need to find a common factor that can be factored out. In this case, both 36 and 16 are divisible by 4. So, we can rewrite the expression as:

36 + 16 = 4(9) + 4(4)

Using the distributive property, we can further simplify this expression:

4(9) + 4(4) = 4 * 9 + 4 * 4

Now, we can calculate the values:

4 * 9 = 36

4 * 4 = 16

Therefore, another way to write 36 + 16 is 4(9) + 4(4).

The sum of the squares of the difference from the mean is therefore;

225 + 0 + 900 + 100 + 100 + 225 = 1550

The variance = The average of the squared deviation is therefore;

Variance = 1550/6 = 258.\(\overline{3}\)

N relates to X's and c in a manner that N is the minimum number n for which the nth random variable Xn is greater than the constant c. This suggests that N is determined by the first n Xn values that are less than or equal to c, since we are taking the minimum of the sequence.

The random variable N and XN are not independent. Intuitively, if XN is less than c, then N cannot be equal to N. We have two cases: if XN < c, then N = N, while if XN > c, then N < N. This means that knowing XN gives information about N, which means they are not independent.

Furthermore, we can prove this rigorously by using conditional probability.

The random variable N is defined as N = min{n : Xn > c}, where X1, X2, X3, ... is a sequence of independent uniform [0, 1] random variables and C is a constant in the range [0, 1]. This implies that N is the minimum index n such that the nth random variable Xn is greater than c.

Since N is the minimum index such that Xn > c, we can say that N is determined by the first n Xn values that are less than or equal to c, as we are taking the minimum of the sequence.
