Answer:

4 is paired with 6 to get 24

Step-by-step explanation:

Here are some examples I got from my math teacher:

So How do you find the factor pairs?

Factor pairs are a set of two integers that give a particular product when multiplied together. For example, 2 and 5 are a factor pair for the product of 10. Factor pairs can be negative numbers, but they must be whole numbers – that means that they can't be a fraction or a decimal.

The derivative of the function f(x) = sin(x) / (1 + cos(x)) is f'(0) = 1/2.

To find the derivative of the function f(x) = sin(x) / (1 + cos(x)), we can use the quotient rule. The quotient rule states that if we have a function of the form h(x) = g(x) / p(x), where g(x) and p(x) are differentiable functions, then the derivative of h(x) is given by:

h'(x) = (g'(x) * p(x) - g(x) * p'(x)) / (p(x))^2

Let's apply the quotient rule to find the derivative of f(x):

f(x) = sin(x) / (1 + cos(x))

g(x) = sin(x)

g'(x) = cos(x)

p(x) = 1 + cos(x)

p'(x) = -sin(x)

Now we can substitute these values into the quotient rule formula:

f'(x) = (cos(x) * (1 + cos(x)) - sin(x) * (-sin(x))) / (1 + cos(x))^2

Simplifying the expression:

f'(x) = (cos(x) + cos^2(x) + sin^2(x)) / (1 + cos(x))^2

      = (cos(x) + 1) / (1 + cos(x))^2

Now, to find f'(0), we substitute x = 0 into the derivative expression:

f'(0) = (cos(0) + 1) / (1 + cos(0))^2

     = (1 + 1) / (1 + 1)^2

     = 2 / 2^2

     = 2 / 4

     = 1/2

Therefore, f'(0) = 1/2.

a) The model for the number of sheep and lambs on farms in the United States from 2000 through 2005 can be represented by L(t) = -4.28 ln(t) + 0.14t + C, where t is the year with t=10 corresponding to 2000, and C is the constant of integration.

b) To use the model for the number of sheep and lambs in 2007, we need to find the value of L(17) since 2007 corresponds to t=17. Plugging t=17 into the model, we can calculate L(17) = -4.28 ln(17) + 0.14(17) + C using the given equation and the constant of integration from the initial condition.

a) To find the model for the number of sheep and lambs, we integrate the given rate of change equation. The integral of dl/dt with respect to t gives L(t) = -4.28 ln(t) + 0.14t + C, where ln(t) is the natural logarithm of t. The constant of integration, C, can be determined using the given information that in 2003 (t=13), the number of sheep and lambs was 6.3 million. Plugging in t=13 and L=6.3 into the model, we can solve for C and obtain the specific equation for the number of sheep and lambs.

b) To find the number of sheep and lambs in 2007 (t=17), we substitute t=17 into the model equation L(t) = -4.28 ln(t) + 0.14t + C. By plugging in the values, we can calculate L(17) = -4.28 ln(17) + 0.14(17) + C using the natural logarithm function and the constant of integration determined in part a).

The probability of the ball landing on a red slot on the next spin is still 18/38 or approximately 0.4737 or 47.37%.

The probability of the ball landing on a red slot on a single spin of a standard roulette wheel is 18/38 or approximately 0.4737 or 47.37%. This is because there are 18 red slots out of a total of 38 slots on the wheel.

The outcome of the previous 210 spins has no effect on the probability of the ball landing on a red slot on the next spin. Each spin is an independent event, and the probability of the ball landing on a red slot remains the same for each spin.

Therefore, even though the ball has landed on a red slot for the past 210 spins, the probability of it landing on a red slot on the next spin is still 18/38 or approximately 0.4737 or 47.37%.

A boolean expression can have one of the two values, true or false and is often used in if statements.

Given: To identify what is used in if statements that has either of the two values, true or false.

What are boolean expressions?

Boolean expressions are logical statements that can either be true or false.

Boolean expressions are used to compare different values which are of the same domain and to verify if the condition of comparison is true or false.

For example: 4 > 5 , is this statement true? With the help of boolean variables "true" and "false" we can say that 4 > 5 is "false"

NOTE: There are two boolean variables : TRUE and FALSE

The boolean value TRUE is equivalent to 1 in the integer domain.

The boolean value FALSE is equivalent to 0 in the integer domain.

The common operators that are often used in boolean expressions are OR, AND and NOT.

For example: 7 > 6 OR 0 < 90

Now 7 > 6 is TRUE, also 0 < 90 is TRUE

So, TRUE OR TRUE gives TRUE

Hence 7 > 6 OR 0 < 90 is TRUE, the condition is verified.

The "if" statement is a conditional statement in programming which when TRUE performs certain given information and if FALSE it either terminates or performs some other statements that may be defined in the else or the FALSE part.

"if" statements works on boolean values TRUE and FALSE.

It's like IF this is TRUE do this or ELSE do that.

The structure of if statement is:

if <condition>

    //statements [executed if condition is TRUE]

else

    //statements [executed if condition is FALSE]

Hence a boolean expression can have one of the two values, true or false and is often used in if statements

If the GPA's are normally distributed, then the percentage of students that have a GPA between 2.5 and 3.7 is (b) 68%.

In order to find the percentage of students at the college with a GPA between 2.5 and 3.7, we need to calculate z-scores for each GPA value and find area under normal distribution curve between those 2 z-scores.

First, we convert 2.5 and 3.7 to z-scores using the formula:

⇒ z = (x - μ)/σ,

where x = GPA value, μ = mean = 3.1 , and σ = standard-deviation = 0.6.

The z-score for 2.5 :

⇒ z = (2.5 - 3.1)/0.6 = -1,

The z-score for 3.7 :

⇒ z = (3.7 - 3.1)/0.6 = 1,

We use a standard normal distribution table to find area under curve between -1 and 1.

we get , P(-1 < Z < 1) = 0.6827,

Gauss-Jordan elimination is a method used to solve a system of linear equations by reducing the augmented matrix of the system to a reduced row-echelon form through a series of elementary row operations.

The process involves manipulating the rows of the augmented matrix to obtain a triangular matrix, where all entries below the diagonal are zero. This is achieved by applying elementary row operations such as adding a multiple of one row to another row or multiplying a row by a scalar.

Once the augmented matrix is in triangular form, further elementary row operations are used to eliminate the nonzero entries above the diagonal. This results in the augmented matrix being in reduced row-echelon form, where the pivot elements are all equal to 1 and the columns corresponding to the pivot elements are linearly independent.

Answer: The coordinates of D are (3,4).

Step-by-step explanation:

Since BE is a tangent to the circle at D, the radius MD will be perpendicular to BE. We can find the slope of BE from its equation y = (1/2)x + c, which is 1/2. The slope of MD will be the negative reciprocal of the slope of BE, which is -2.

Since the point M is the center of the circle, the coordinates of M are (-1, 2). We can use the point-slope form of a line to find the equation of the line passing through M with slope -2:

y - 2 = -2(x + 1)

y - 2 = -2x - 2

y = -2x

This is the equation of the radius MD. To find the coordinates of D, we need to find where this line intersects the circle. Substituting y = -2x into the equation of the circle, we get:

x^2 + 2x + (-2x)^2 - 4(-2x) + 5 = 0

5x^2 + 8x + 5 = 0

Solving this quadratic equation using the quadratic formula, we get:

x = (-8 ± sqrt(8^2 - 4(5)(5))) / (2(5))

x = (-8 ± sqrt(24)) / 10

x = (-4 ± sqrt(6)) / 5

Substituting this value of x back into the equation of the radius MD, we get:

y = -2(-4 + sqrt(6)) / 5

y = (8 - 2sqrt(6)) / 5

Therefore, the coordinates of D are (3, 4).

====================================================

Explanation:

You can factor x^2+6x+9 into (x+3)^2, which turns into 1(x - (-3) )^2 + 0

So y = x^2+6x+9 becomes y = 1(x - (-3) )^2 + 0

That matches with vertex form y = a(x-h)^2 + k

The vertex is (-3,0). The y coordinate of the vertex directly tells us the minimum value. We know we have a minimum because a = 1 is positive. If a < 0, then we'd have a max y value instead.

-------------------

Alternatively, compare y = x^2+6x+9 to the form y = ax^2+bx+c

We see that a = 1, b = 6, c = 9

The x coordinate of the vertex is

h = -b/(2a)

h = -6/(2*1)

h = -3

The x coordinate of the vertex is x = -3. Plug this into the original equation to find the y coordinate of the vertex

y = x^2 + 6x + 9

y = (-3)^2 + 6(-3) + 9

y = 9 - 18 + 9

y = -9 + 9

y = 0

The y coordinate of the vertex is y = 0. This is the smallest y output possible.

D.11.1

Step-by-step explanation:

first, let's use the SOHCAHTOA strategy. for people that don't know, it means:

Sine(angle)= side Opposite to the angle/Hypotenuse (SOH)

Cosine(angle)= side Adjacent to the angle/Hypotenuse (CAH)

Tangent(angle)= side Opposite to the angle/side Adjacent to the angle (TOA)

now, since the question describes both the hypotenuse and the side opposite to the angle, we will use Sine to find the length, according to the SOHCAHTOA strategy. This means that the equation will be:

Sin(46)=8/x

Now, we punch in the first half of our equation, Sin(46), into the calculator. it should pop up as:

Sin(46)=0.7193398

now, we substitute that in our original equation, and make it like this:

0.7193398=8/11.1

now, everything will be pretty easy. First, round the decimal into something easier, in this case, 18/25. Now, the equation will be:

18/25=8/x

from here, we can cross multiply to get the x. your fraction should be:

18x/200

so, x=200/18. convert it into a decimal, we get:

11.1111111...

now, we find the number closest to 11.11, which is 11.1, making the answer 11.1, or D.

The magnitude of the force per unit length that each wire exerts on the other wire is 3 × 10⁻⁷ N/m.

Using Ampere's law, the force per unit length (F/L) between two parallel wires carrying currents I1 and I2 and separated by a distance d can be calculated as:

F/L = (μ0 ⨯ I1 ⨯ I2) / (2 ⨯ π ⨯ d)

Where μ0 is the permeability of free space (4π × 10⁻⁷ T⋅m/A),

I1 is the current in the first wire (4.00 A),

I2 is the current in the second wire (6.00 A), and d is the distance between the wires (0.400 m).

F/L = (4π × 10⁻⁷ T⋅m/A ⨯ 4.00 A ⨯ 6.00 A) / (2 ⨯ π ⨯ 0.400 m)
