The prove that triangle ABE is congruent to triangle CDE is given below

Generally, To prove that triangle ABE is congruent to triangle CDE, we need to show that they have the same size and shape.

First, we can see that angle AED and angle CEB are opposite angles and therefore congruent, since AB || DC.

Also, since line AB = line DC, we know that segment AE is congruent to segment CE and segment BE is congruent to segment DE.

Using these congruent sides and the congruent angle, we can apply the Side-Angle-Side (SAS) congruence criterion to conclude that triangle ABE is congruent to triangle CDE.

Therefore, we have proven that triangle ABE is congruent to triangle CDE.

Answer:

We can use the given equation to solve for the advertising expenditures needed to achieve the target sales volume of $125,000:

125 = 45.15 + 0.54x

where x is the advertising expenditures in thousands of dollars.

Simplifying the equation:

0.54x = 125 - 45.15

0.54x = 79.85

x = 79.85 / 0.54

x ≈ 147.69

Therefore, the sales manager should allocate about $147,690 for advertising in the budget to achieve the target sales volume of $125,000.

The system of inequalities is y < x + 2 and 5y ≤ -2x + 10

From the question, we have the following parameters that can be used in our computation:

The blue and the red lines

For the blue line, we have the following points

(0, 2) and (-2, 0)

The equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 2

Using the points, we have

-2m + 2 = 0

m = 1

So, we have

y = x + 2

The lower part is shaded and the line is a dotted line

So, we have

y < x + 2

For the red line, we have the following points

(0, 2) and (5, 0)

The equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 2

Using the points, we have

5m + 2 = 0

m = -2/5

So, we have

y = -2/5x + 2

The lower part is shaded and the line is a shaded line

So, we have

y ≤ -2/5x + 2

Multiply through by 5

5y ≤ -2x + 10

Hence, the system is y < x + 2 and 5y ≤ -2x + 10

This could result in one, two, or multiple points of intersection, depending on the specific values of the deposits and the rates of increase.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

we can assume that the graph of Cera's and Bethany's savings accounts will show the total amount of money in their accounts after a certain number of weeks.

Since both Cera and Bethany deposit the same amount of money and make the same additional deposits each week, their savings will increase at the same rate. Therefore, the graph will likely show two parallel lines that start at $20 and increase by $15 per week.

The number of solutions modeled by the graph will depend on whether the two lines ever intersect. If the lines do not intersect, then there is no solution to the system of equations that model the two savings accounts. In other words, there is no point at which the total amount of money in both accounts is the same.

On the other hand, if the lines do intersect, then there is at least one solution to the system of equations. In this case, the point of intersection represents the week at which the total amount of money in both accounts is the same.

To change the situation so that the graphs model a different number of solutions, we could change the initial deposit or the amount of money deposited each week for one or both of the savings accounts. For example, if Cera starts with a higher initial deposit than Bethany, or if Cera deposits more money each week, then their savings will increase at different rates and the lines on the graph will not be parallel.

Therefore, This could result in one, two, or multiple points of intersection, depending on the specific values of the deposits and the rates of increase.

Comparing the interest rates of Jane and Tommy, we can say that Tommy's bank is better because he earns more amount of money for less principal amount.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.

Given,

Interest earned by Tommy SI = $140

Time t = 5 years

Principal amount P = $400

Interest earned by Jane SI = $132

Time t = 4 years

Principal amount P = $600

Simple interest SI = (P × r × t)/100

where r = interest rate

For Tommy,

140 = ( 400 × r × 5) /100

r = 7%

For Jane,

132 = ( 600 × r × 4) / 100

r = 5.5%

Therefore comparing the interest rates of Jane and Tommy, we can say that Tommy's bank is better because he earns more amount of money for the less principal amount.

A = jumlah uang tabungan akhir

P = jumlah uang tabungan awal

r = tingkat bunga per bulan (dalam desimal)

n = jumlah bulan

Dalam kasus ini, P = Rp.2.000.000,00, r = 0,5% atau 0,005 per bulan, dan n = 10 bulan.

Maka,

A = 2.000.000(1 + 0,005)^10

= 2.000.000(1,005)^10

= 2.000.000(1,0512)

A histogram is a graph used to represent the frequency distribution of a few data points of one variable. Histograms often classify data into various “bins” or “range groups” and count how many data points belong to each of those bins.

The histogram shows the number of items sold at various price ranges, and the heights of the bars indicate the number of items sold within each price range.

The data set that is represented in the histogram is:

{0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}

This is because the histogram has four bars with heights of 2, 4, 0, and 1, which correspond to the number of items sold in each of the four price ranges shown.

The values in the data set correspond to the boundaries of these price ranges. For example, the first bar represents the price range from $0.00 to $2.50, so the data set includes the value 2.00 (which is within this range) and the value 2.52 (which is just outside this range).

Similarly, the second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 (which is within this range) and the value of 5.00 (which is the upper boundary of this range).

Therefore, the second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 and the value of 5.00 the correct answer is {0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}

Answer:

the frequency of the recessive allele in the population is 0.5 or 50%.

Step-by-step explanation:

In a population in Hardy-Weinberg equilibrium, the frequency of alleles remains constant from generation to generation. According to the Hardy-Weinberg law, if p is the frequency of the dominant allele and q is the frequency of the recessive allele, then:

p + q = 1

and

p^2 + 2pq + q^2 = 1

where p^2 represents the frequency of homozygous dominant individuals, 2pq represents the frequency of heterozygous individuals, and q^2 represents the frequency of homozygous recessive individuals.

Given that the frequency of dominant yellow-flowered plants is 50%, or 0.5, we can assume that p = 0.5. Substituting into the first equation, we get:

0.5 + q = 1

Solving for q, we get:

q = 1 - 0.5

q = 0.5

Therefore, the frequency of the recessive allele in the population is 0.5 or 50%.

3. The measure of angle ∠2 is 60° which is an acute angle.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

1.  ∠1 = 6x + 45 and ∠3 = 9x + 15

Angle ∠1 and angle ∠3 are opposite angles. Then the equation is given as,

∠1 = ∠3

9x + 15 = 6x + 45

9x - 6x = 45 - 15

3x = 30

x = 30 / 3

x = 10

2.  Angle ∠2, angle ∠3, and angle ∠4 are supplementary angles. Then the equation is given as,

∠2 + ∠3 + ∠4 = 180°

90° + ∠3 + ∠4 = 180°

∠3 + ∠4 = 90°

3.  Angle ∠1 is 120°, then the measure of angle ∠2 is given as,

a. The six trigonometric functions of the angle β are:

sin β = 7/25

cos β = 24/25

tan β = 7/24

csc β = 25/7

sec β = 25/24

cot β = 24/7

b. Using trigonometric identity, cos X + (sin X)(tan X) = 1

We can use the given value of cos β = 24/25 to find the other trigonometric functions of the angle β.

Let's draw a right triangle with angle β, adjacent side of length 24, and hypotenuse of length 25 (since cos β = adjacent/hypotenuse):

Using the Pythagorean theorem, we can find the opposite side:

Opposite side = sqrt(hypotenuse^2 - adjacent^2) = sqrt(25^2 - 24^2) = sqrt(49) = 7

So the triangle is:

Now we can find the other trigonometric functions:

sin β = opposite/hypotenuse = 7/25

cos β = adjacent/hypotenuse = 24/25

tan β = opposite/adjacent = 7/24

csc β = hypotenuse/opposite = 25/7

sec β = hypotenuse/adjacent = 25/24

cot β = adjacent/opposite = 24/7

2. We can use the trigonometric identity for tangent:

tan X = sin X / cos X

to rewrite the expression as:

cos X + (sin X)(sin X / cos X)

Multiplying through by cos X, we get:

(cos X)(cos X) + (sin X)(sin X)

Using the Pythagorean identity:

(sin X)^2 + (cos X)^2 = 1

we can simplify further:

1 - (cos X)^2 + (cos X)^2 = 1

So the final simplified expression is equal to 1

3. We can start with the left-hand side of the equation and manipulate it using the definitions of the trigonometric functions and the Pythagorean identity until we arrive at the right-hand side:

tan²α(csc²α - 1)

= (sin²α/cos²α)((1/sin²α) - 1)

= (sin²α/cos²α - sin²α/cos²α)

= 0

Now, let's look at the right-hand side:

1

We see that the left-hand side simplifies to 0, while the right-hand side is 1. Therefore, the identity is not true for all values of α.

We can see this more clearly by picking a specific value of α and evaluating both sides of the equation. For example, let's take α = 45°:

tan²45°(csc²45° - 1) = (1/1)((2/1) - 1) = 1

1 = 1

So the identity holds for α = 45°, but we have already shown that it does not hold for all values of α. Therefore, the identity is not true for all values of α.
