Answer: x^2+3x+5

Step-by-step explanation:

Substitute (x+4) in so that you get f(x)=(x+4)^2-5(x+4)+9. Then expand so you get x^2+8x+16-5x-20+9. Now simplify and you get x^2+3x+5. That is your final answer.

The required pounds of Bolivian coffee and Colombian coffee are 2500 and 1500 respectively.

A equation is supposed to be linear equation in two factors in the event that it is written as ax + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are direct conditions in two factors.

Let x be the pound of Bolivian coffee and y is that of Colombian coffee.

Bolivian coffee sells for $4.59 per pound, and Colombian coffee sells for $5.95 per pound and whole mixture sells for $5.10.

So,  4.59x + 5.95y = 5.10(4000)

4.59x + 5.95y = 20400--------------------(1)

and x + y = 4000-----------------------------(2)

On solving above two equation, we get

x = 2500 pounds and y = 1500 pounds

Thus, required pounds of two coffees are 2500 and 1500.

The normal distribution that best approximates X is N(18, 3).To determine the normal distribution that best approximates the number of heads (X) when a fair coin is flipped 36 times, we can use the Central Limit Theorem.

According to the Central Limit Theorem, for a large enough sample size (in this case, 36 coin flips), the distribution of the sample mean will be approximately normal, regardless of the underlying distribution.

Since the coin is fair, the probability of getting a head (success) is 0.5, and the probability of getting a tail (failure) is also 0.5.

The mean of the binomial distribution is given by μ = n * p, where n is the number of trials and p is the probability of success. In this case, μ = 36 * 0.5 = 18.

The standard deviation of the binomial distribution is given by σ = sqrt(n * p * (1 - p)), where n is the number of trials and p is the probability of success. In this case, σ = sqrt(36 * 0.5 * (1 - 0.5)) = sqrt(9) = 3.

Since X represents the number of heads, which is a count, we can approximate it with a normal distribution with mean μ = 18 and standard deviation σ = 3.

Therefore, the normal distribution that best approximates X is N(18, 3).

6 and 7

Step-by-step explanation:

Consider the perfect squares on either side of 45, that is

36 < 45 < 49 , then

\(\sqrt{36}\) < \(\sqrt{45}\) < \(\sqrt{49}\) , that is

6 < \(\sqrt{45}\) < 7

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

Step-by-step explanation:

Given that three charges (-25 nC, 79.1nC, and −55.9nC) are placed at three of the four corners of a square with sides of length 22.2 cm. We need to determine the value of the electric potential (in V) at the empty comer if the positive charge is placed in the opposite corner.

The formula for the electric potential at a point in space is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) + ….. ]where;k = Coulomb's constant (8.99 × 10^9 Nm²/C²)q1, q2, q3,…. are the charges at the cornersr1, r2, r3,…. are the distances from the corner to the point whose potential is being calculated Now we can calculate the electric potential at the empty corner as follows;The three charges can be represented as shown below:Charges at corners of a square

The distance from any corner to the opposite corner (where the positive charge is placed) is given by d = √[ (22.2 cm)² + (22.2 cm)² ] = 31.4 cmTherefore, the electric potential at the empty corner is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) ]Here, q1 = -25 nC, q2 = -55.9 nC, q3 = 79.1 nC, r1 = r2 = r3 = d = 31.4 cm = 0.314 mPlugging in the values we get;V = 8.99 × 10^9 [ (-25 × 10^-9 / 0.314) + (-55.9 × 10^-9 / 0.314) + (79.1 × 10^-9 / 0.314) ]= 8.99 × 10^9 [ -0.0795 - 0.1783 + 0.252 ]= 8.99 × 10^9 × 0.0052= 46.8 VTherefore, the value of the electric potential at the empty comer if the positive charge is placed in the opposite comer is 46.8 V.

The value of 123cm in inches, which is a unit of distance, is 48.46 inches

What is meant by distance?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

The International System of Units defines a metre as the unit of distance.

Some other commonly used units of distance are kilometres, centimetres, inches, yards and so on.

For the given question we are asked to find the value 123cm in inches.

According to the unit conversion charts,

1 cm = 0.394 inches

Therefore the value of 123cm in inches, which is a unit of distance, is

123* 0.394 = 48.46 inches

If this is a parallelogram:

∠y = 112°

corners opposite the 112° corners = 68°      [(360° - 112° - 112°)/2 = 68°]

∠z = 68° - 40° = 28°

∠x = ∠z = 28°

Answer:

x = 28°, y = 112°, z = 28°

Step-by-step explanation:

suppose it's a parallelogram,

in a parallelogram, opposite angles are congruent: y = 112°

40 + 112 + x = 180

=> x = 28°

If 2 lines are cut by a transversal, then the alternate interior angles are congruent: x = z => 28° = z

The given differential equation is y" - 5y + 6 = 15 + 3% + 10 sin c.

Let us first solve the homogeneous differential equation which is y" - 5y + 6 = 0.The characteristic equation is m² - 5m + 6 = 0

 Factorizing the above equation we get:

(m - 3)(m - 2) = 0So, m = 2 or m = 3

The general solution of the homogeneous differential equation is given by:

yh = c₁e^(2x) + c₂e^(3x) -----(1)

Now, let us solve the given differential equation using the method of undetermined coefficients.

The particular integral of the given differential equation is of the form

yᵠ = A + Bt + C sin c + D cos c + E sin 2c + F cos 2c

Differentiating twice we get,

yᵠ" = 4E sin 2c - 4F cos 2c + C sin c + D cos c

Substituting yᵠ and yᵠ" in the given differential equation we get,

4E sin 2c - 4F cos 2c + C sin c + D cos c - 5(A + Bt + C sin c + D cos c + E sin 2c + F cos 2c) + 6 = 15 + 3% + 10 sin c

Simplifying the above equation we get,

(4E - 5E) sin 2c + (4F - 5F) cos 2c + (C - 5C) sin c + (D - 5D) cos c - 5A - 5Bt + 6 = 15 + 3% + 10 sin c- E sin 2c - F cos 2c - C sin c - D cos c + 5A + 5Bt

= 3% + 10 sin c + 9 -----(2)

Comparing the coefficients of like terms on both sides we get,

4E - 5E = 0

=> E = 0

Similarly, we get,

4F - 5F = 0

=> F = 0C - 5C = 10

=> C = -2D - 5D

= 3%

=> D = -3%

A = 1 and B = 0

Substituting these values in equation (2) we get,

yᵠ = 1 - 3 cos c - 2 sin c

Now, the general solution of the given differential equation is given by:

y = yh + yᵠ = c₁e^(2x) + c₂e^(3x) + 1 - 3 cos c - 2 sin c

The equation of circle D is (x + 2)2 + y² = 32 then the points (-6,-4) and (-4,6) lie on circle D

The equation of a circle with center (h,k) and radius r is (x - h)² + (y - k)² = r².

This is called the standard form of the equation of a circle.

In the given equation, (x + 2)² + y² = 32, we can see that the center of the circle is (-2, 0) and the radius is √32 = 4√2.

To determine which points lie on the circle, we substitute the x and y coordinates of each point into the equation and check if the equation is true.

If it is true, then the point lies on the circle.

Let us check if (-6, -4) lies on the circle, we substitute x = -6 and y = -4 into the equation:

(-6 + 2)² + (-4)² = 32

(-4)² + (-4)² = 32

16 + 16 = 32

32 = 32

Since the equation is true, (-6, -4) lies on the circle.

7.2 ÷ 3.6 = 2.0 and (8 - 5) = 3. Therefore, the quotient is 2.0 x \(10^{3}\) in scientific notation.

The quotient of 7.2 x \(10^{8}\) and 3.6 x \(10^{5}\) can be found by dividing the coefficients and subtracting the exponents.
we can talk about the importance of scientific notation in representing large and small numbers in a concise and manageable way. Scientific notation allows us to express numbers as a coefficient multiplied by a power of 10, which makes it easier to work with very large or very small numbers without having to write out all the digits.
In this specific problem, we have two numbers expressed in scientific notation that we need to divide. By following the rules of scientific notation, we can divide the coefficients and subtract the exponents to find the quotient. The answer is expressed as 2.0 x  \(10^{3}\) , which is a much more manageable representation of the result than writing out all the digits of the quotient.
In conclusion, scientific notation is an important tool in mathematics and science for representing large and small numbers in a concise and practical way.
