If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, then each missing measure fm=88 and ce=44.

The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.

Step 1: Identify each vertex's coordinates.

Step 2: Add together and divide by three all the x values from the coordinates of the three vertices.

Step 3: Add together all the y values from the three vertices and divide the result by three.

Step 4: The centroid coordinate is determined from the values collected in stages 2 and 3.

the ratio of both segments is 2:1.

where;

am = 44 and dm = 23

the longer segment is double of shorter one:

2*23 = 46.

Therefore,

fm = 46-23

= <<23=23>>23

now finding ce:

= 2*44

= 88, so

ce measures

= 88-44

=44.

The probability that a family with 4 children has no more than 3 boys is 15/16.

To find the probability that a family with 4 children has no more than 3 boys, we can use the binomial distribution.

The binomial distribution is used to calculate the probability of obtaining a certain number of successes (boys in this case) in a fixed number of trials (children in this case), where each trial has only two possible outcomes (boy or girl) and the trials are independent.

Let X be the number of boys in the family. We want to find P(X ≤ 3), which is the probability of having no more than 3 boys. Since the probability of having a boy is 1/2 and the trials are independent, we can use the binomial distribution formula:

P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

= (1/2)⁴ + 4(1/2)⁴ + 6(1/2)⁴ + 4(1/2)⁴

= 15/16

The area of the parallelogram with sides measuring 44, 38, and an included angle of 35 degrees is approximately 1,008.77 square units.

To find the area of a parallelogram, we need to know the length of one side and the perpendicular height. However, in this case, we are given the lengths of two adjacent sides (44 and 38) and the measure of the included angle (35 degrees). To find the area, we can use the formula:

Area = side1 * side2 * sin(angle)

Plugging in the values, we have:

Area = 44 * 38 * sin(35 degrees)

To calculate this, we convert the angle from degrees to radians since the trigonometric functions in most programming languages work with radians. Using the conversion formula (radians = degrees * pi / 180), we find that 35 degrees is approximately 0.610865 radians.

Area = 44 * 38 * sin(0.610865)

Using a scientific calculator or a programming language, we can evaluate sin(0.610865) to be approximately 0.5815.

Area = 44 * 38 * 0.5815

≈ 1008.77 square units

Therefore, the area of the parallelogram is approximately 1,008.77 square units.

Therefore , the solution of the given problem of function comes out to be Nolan dropped the ball from a height of 12 units at the beginning.

The study of mathematics includes numbers, symbols, and their parts, as well as anatomy, building, and both actual and hypothetical geographic locations. The relationships between different components, each of which has a corresponding result, are described by a function. A function is made up of a variable of distinct components that, when put together, produce specific results for each input.

Here,

Assume that h represents the original height at which Nolan threw the ball. The object bounces once and rises to a height of 4, so after the bounce it has a height of h + 4.

=> h = k f(1) (1)

where k is a constant that denotes how much energy the object retains after each bounce.

=> h = k(4) (4)

The knowledge that the ball returns to a height of 4 on the first bounce must be used to determine the value of k:

=> 4 = k f(1) (1)

=> 4 = k (4/3)

=> k = 3

When we put this number of k back into the equation as a replacement for h, we get:

=> h = k(4) = 3(4) = 12

Nolan dropped the ball from a height of 12 units at the beginning.

Let the amount he invested at 9% = x

Let the amount he invested at 11% = y

He invested the same amount in both stocks, so x=y

Interest(i)=principle(p)*rate(r)*time(t), but unless they specify that the time is different than one, i=p*r.

So the amount of interest he gets at 9%= 0.09x

The amount of interest he gets at 11% = 0.11y

Add the two together and your interest is=430

Therefore your system of linear equations is:

x=y

0.09x + 0.11y=430

----------------Substitute the first equation into the second and you have:

0.09x+0.11(x)=430

0.2x=430

0.2x/0.2=430/0.2

x = $2,150 (the amount he invested at 9%)

y=x so y=$2,150 (the amount he invested at 11%)

Add the two investments together to find out how much he invested all together:

$2,150+$2,150 = $4,300 is the amount he has invested altogether.

Therefore the amount he invested on each are $2150 and $2150, while the total investment altogether = $4300

the power series representation for f(x) is:

f(x) = ∑((-1)^n * 4^n * x^(n+1)), n=0 to infinity.

To find the power series representation of f(x), we will use the geometric series formula:

1 / (1 + t) = 1 - t + t^2 - t^3 + ...

We start by factoring the denominator of f(x):

f(x) = x / (1+4x)^2 = x / (1 + 8x + 16x^2)

We can rewrite the denominator as:

1 + 8x + 16x^2 = (1 + 2(2x))^2

Using this, we can write:

f(x) = x / (1 + 2(2x))^2

We can now substitute t = -2x into the geometric series formula to get:

1 / (1 + (-2x)) = 1 + (-2x) + (-2x)^2 + (-2x)^3 + ...

Substituting t = -2x into the formula gives:

f(x) = x / (1 + 2(2x))^2 = x / (1 + (-2x))^2 = x (1 + (-2x) + (-2x)^2 + (-2x)^3 + ...)^2

We need to square the series because the denominator is squared. Simplifying, we get:

f(x) = x (1 - 4x + 4x^2 - 4x^3 + ...) = x - 4x^2 + 4x^3 - 4x^4 + ...

To determine which payment plan the real estate investor would prefer, we need to compare the present value of each payment option. Assuming a discount rate of 0%, meaning no time value of money is considered, we can directly compare the payment amounts.

1. Payment of $2,000 at the first of each month: This results in a total payment of $24,000 over the 12-month lease.

2. Upfront payment of $24,000: This option requires paying the full amount at the beginning of the lease.

3. Payment of $2,000 at the end of each month: Similar to option 1, this results in a total payment of $24,000 over the 12-month lease.

4. Upfront payment of $12,000 and $12,000 half-way through the lease: This option requires paying $12,000 at the beginning of the lease and another $12,000 halfway through the lease.

Since all the payment options have a total cost of $24,000, the real estate investor would likely prefer the payment plan that offers more flexibility or matches their cash flow preferences. Options 1 and 3 provide the investor with the option to pay monthly, while options 2 and 4 require a larger upfront payment. The choice would depend on the investor's financial situation and preferences.

The solution to the given initial value problem (IVP) using Laplace transform is y(t) = e^t + e^(3t).

To solve the IVP using Laplace transform, we first take the Laplace transform of the given differential equation and apply the initial conditions.

Applying the Laplace transform to the differential equation y"-4y' + 3y = 0, we get s²Y(s) - sy(0) - y'(0) - 4(sY(s) - y(0)) + 3Y(s) = 0, where Y(s) represents the Laplace transform of y(t).

Using the initial conditions y(0) = 1 and y'(0) = 2, we substitute the values into the equation above. This yields the equation s²Y(s) - s - 2 - 4(sY(s) - 1) + 3Y(s) = 0.

Simplifying the equation, we obtain (s² - 4s + 3)Y(s) = s + 2 + 4.

Solving for Y(s), we have Y(s) = (s + 6) / (s² - 4s + 3).

Using partial fraction decomposition, we can express Y(s) as Y(s) = A / (s - 1) + B / (s - 3).

Solving for A and B, we find A = 3 and B = -2.

Therefore, Y(s) = 3 / (s - 1) - 2 / (s - 3).

Applying the inverse Laplace transform, we obtain y(t) = e^t + e^(3t).

Thus, the solution to the given IVP is y(t) = e^t + e^(3t).

Writing Algebraic Expressions

Group workProblem: Ms. Jensen likes to divide her class into groups of 2. Use mathematical symbols to represent all the students in her class.

Solution: Let g represent the number of groups in Ms. Jensen's class.

Then 2 · g, or 2g can represent "g groups of 2 students".

In the problem above, the variable g represents the number of groups in Ms. Jensen's class. A variable is a symbol used to represent a number in an expression or an equation. The value of this number can vary (change). Let's look at an example in which we use a variable.

Example 1: Write each phrase as a mathematical expression.

Phrase Expression

the sum of nine and eight 9 + 8

the sum of nine and a number x 9 + x

The expression 9 + 8 represents a single number (17). This expression is a numerical expression, (also called an arithmetic expression). The expression 9 + x represents a value that can change. If x is 2, then the expression 9 + x has a value of 11. If x is 6, then the expression has a value of 15. So 9 + x is an algebraic expression. In the next few examples, we will be working solely with algebraic expressions.

Example 2: Write each phrase as an algebraic expression.
