Explanation:

We'll use the distance formula here. Rather than compute the distance d based on two points given, we'll go in reverse to use the given distance d to find what the coordinate must be to satisfy the conditions.

We're given that d = 5

The first point is \((x_1,y_1) = (5,2)\) and the second point has coordinates of \((x_2,y_2) = (x,5)\) where x is some real number.

We'll plug all this into the distance formula and solve for x.

\(d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\5 = \sqrt{(5-x)^2+(2-5)^2}\\\\5 = \sqrt{(5-x)^2+(-3)^2}\\\\5 = \sqrt{(5-x)^2+9}\\\\\sqrt{(5-x)^2+9} = 5\\\\(5-x)^2+9 = 5^2\\\\(5-x)^2+9 = 25\\\\(5-x)^2 = 25-9\\\\(5-x)^2 = 16\\\\5-x = \pm\sqrt{16}\\\\5-x = 4 \ \text{ or } \ 5-x = -4\\\\-x = 4-5 \ \text{ or } \ -x = -4-5\\\\-x = -1 \ \text{ or } \ -x = -9\\\\x = 1 \ \text{ or } \ x = 9\\\\\)

This means that if we had these three points

Then segments AB and AC are each 5 units long.

To find the probability of getting 10 or more successes in a binomial experiment with p = 0.63 and n = 11 trials, we can use the cumulative probability function.

P(X ≥ 10) = 1 - P(X < 10)

Using a binomial probability formula, we can calculate the probability of getting exactly k successes:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where C(n, k) represents the binomial coefficient.

Let's calculate the probability for each value from 0 to 9 and subtract it from 1 to get the probability of 10 or more successes:

P(X < 10) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 9)

P(X < 10) = Σ[C(11, k) * p^k * (1 - p)^(11 - k)] for k = 0 to 9

Using this formula, we can calculate the probability:

P(X < 10) ≈ 0.121

Therefore, the probability of getting 10 or more successes in the binomial experiment is:

P(X ≥ 10) ≈ 1 - P(X < 10) ≈ 1 - 0.121 ≈ 0.879

Rounding to three decimal places, the probability is approximately 0.879.

"Triangle CFE is congruent to triangle PTR" is true.

If Triangle CFE is congruent to triangle PTR, we can make the following statements:
The corresponding sides of the triangles are congruent:

This means that CF = PT, FE = TR, and CE = PR.
The corresponding angles of the triangles are congruent:

This means that angle CFE is congruent to angle PTR, angle FCE is congruent to angle PRT, and angle ECF is congruent to angle TPR.
The triangles are equal in area: Since the triangles are congruent, they have the same shape and size. Therefore, they will have the same area.
The triangles can be superimposed on each other: This means that we can place triangle CFE on top of triangle PTR in such a way that their corresponding sides and angles overlap.
If we know the measurements of the sides and angles of one triangle, we can find the measurements of the sides and angles of the other triangle: Since the triangles are congruent, we know that their corresponding sides and angles are equal.

Therefore, if we know the measurements of the sides and angles of one triangle, we can find the measurements of the sides and angles of the other triangle by using the congruence criteria.
In conclusion, if Triangle CFE is congruent to triangle PTR, we can make several statements about their corresponding sides and angles, their areas, and their ability to be superimposed on each other.

We can also use the congruence criteria to find the measurements of the sides and angles of one triangle if we know the measurements of the sides and angles of the other triangle.

You will be able to withdraw approximately $3,076.32 at the end of 5 years.

To calculate the amount you will be able to withdraw at the end of 5 years, we can use the future value formula for compound interest.

The formula for calculating the future value (FV) of a present value (PV) invested at an annual interest rate (r) for a certain number of years (t) is:

\(FV = PV * (1 + r)^t\)

Given:

PV = $2,300

r = 6% = 0.06 (decimal representation)

t = 5 years

Substituting these values into the formula, we get:

FV = $2,300 * \((1 + 0.06)^5\)

Calculating the expression inside the parentheses:

\((1 + 0.06)^5 = 1.338225\)

Multiplying the present value by this factor:

FV = $2,300 * 1.338225

FV ≈ $3,076.32

Therefore, you will be able to withdraw approximately $3,076.32 at the end of 5 years.

A combination of the sum of two complex numbers is 15 - 19i

To find the sum of two complex numbers, add their real parts separately and add their imaginary parts separately.Now, we need to find the sum of the following complex numbers.

(-4i) + (10 - 5i) -3

5i -3 - 5i

6 - 4i 6 - 6i

Add the real parts, which are (-4) and 10.

Therefore, the real part is (10 - 4) = 6.

Add the imaginary parts, which are (-5) and (-3).

Therefore, the imaginary part is (-5 - 3) = -8.

Thus, the sum of (-4i) and (10 - 5i) is 6 - 8i.

Now, we need to find the sum of the following complex numbers.

(-3 − 5i) + (6 − 4i) + (6 − 6i)

First, we add (-3 − 5i) and (6 − 4i) to find the sum.

(−3 − 5i) + (6 − 4i) = (3 − 5i)

Then we add (3 − 5i) and (6 − 6i) to find the sum.

(3 − 5i) + (6 − 6i) = 9 − 11i

Therefore, the sum of (-3 - 5i), (6 - 4i) and (6 - 6i) is 9 - 11i.

Now we have to write our answer as a combination of the sum of two complex numbers, which we found earlier.

6 - 8i + 9 - 11i = 15 - 19i

Thus, the final answer is 15 - 19i.

College students are often targeted by credit card companies with advertisements. A survey conducted at a university found that 65% of students had opened a new credit card account within the past year.

To answer your question, we need to use basic probability concepts. If 65% of students surveyed had opened a new credit card account within the past year, then the probability that a randomly chosen student has not opened a new credit card account is 1 - 0.65 = 0.35 or 35%.
Now, let's say we want to find the number of students we need to survey before finding one who had not opened a new account in the past year. This is equivalent to finding the number of trials before we get a success (i.e., finding a student who had not opened a new account).
We can use the formula for geometric distribution, which is:
P(X = k) = (1 - p)^(k-1) * p
where X is the number of trials before the first success, p is the probability of success, and k is the number of trials.
In our case, p = 0.35 (the probability of finding a student who had not opened a new account) and we want to find k (the number of trials).
We can set the probability to find a student who had not opened a new account to be greater than 0.5 (i.e., 50%) to ensure a high chance of success. So, we have:
P(X >= k) = 0.5
(1 - 0.35)^(k-1) * 0.35 = 0.5
Taking the logarithm of both sides and solving for k, we get:
k = log(0.5) / log(0.65)
k ≈ 3
Therefore, we would expect to survey about 3 students before finding one who had not opened a new credit card account in the past year.

In conclusion, college students are often targeted by credit card companies with advertisements. A survey conducted at a university found that 65% of students had opened a new credit card account within the past year. This statistic suggests that credit cards are popular among college students, who may be looking for ways to finance their education and living expenses. However, it is also important to note that credit card debt can be a major burden for students, especially if they are unable to make timely payments or manage their finances effectively. The probability analysis conducted in this answer shows that we would expect to survey only about 3 students before finding one who had not opened a new credit card account in the past year. This highlights the need for financial education and literacy programs for college students, to help them make informed decisions about credit card use and avoid potential debt problems.

The area of polygon j is approximately 59.81 units.

To determine the area enclosed by each polygon, we first need to identify the shape of the polygon and its dimensions.

Once we have this information, we can use the formula for finding the area of that particular shape.

a. From the given diagram, we can see that polygon a is a rectangle with a length of 5 units and a width of 3 units.

The formula for finding the area of a rectangle is A = l x w, where A is the area, l is the length, and w is the width.

Substituting the values, we get:
A = 5 x 3 = 15 units

Therefore, the area of a polygon a is 15 units.

b. Polygon b is a triangle with a base of 5 units and a height of 4 units.

The formula for finding the area of a triangle is A = (1/2) x b x h, where A is the area, b is the base, and h is the height.

Substituting the values, we get:
A = (1/2) x 5 x 4 = 10 units

Therefore, the area of polygon b is 10 units.

c. Polygon c is a trapezoid with a height of 3 units, a base of 6 units, and a top base of 4 units.

The formula for finding the area of a trapezoid is A = (1/2) x (b1 + b2) x h, where A is the area, b1 and b2 are the lengths of the bases, and h is the height.

Substituting the values, we get:
A = (1/2) x (6 + 4) x 3 = 15 units

Therefore, the area of polygon c is 15 units.

d. Polygon d is a parallelogram with a base of 4 units and a height of 3 units. The formula for finding the area of a parallelogram is A = b x h, where A is the area, b is the base, and h is the height. Substituting the values, we get:
A = 4 x 3 = 12 units

Therefore, the area of polygon d is 12 units.

e. Polygon e is a kite with a diagonal of 6 units and a diagonal of 4 units.

The formula for finding the area of a kite is A = (1/2) x d1 x d2, where A is the area, d1 and d2 are the lengths of the diagonals.

Substituting the values, we get:
A = (1/2) x 6 x 4 = 12 units

Therefore, the area of polygon e is 12 units.

f. Polygon f is a square with a side length of 3 units. The formula for finding the area of a square is A = s^2, where A is the area and s is the length of a side.

Substituting the value, we get:
A = 3^2 = 9 units

Therefore, the area of polygon f is 9 units.

g. Polygon g is a rhombus with diagonals of 4 units and 6 units.

The formula for finding the area of a rhombus is A = (1/2) x d1 x d2, where A is the area and d1 and d2 are the lengths of the diagonals. Substituting the values, we get:
A = (1/2) x 4 x 6 = 12 units

Therefore, the area of polygon g is 12 units.

h. Polygon h is a regular hexagon with a side length of 2 units.

The formula for finding the area of a regular hexagon is A = (3√3/2) x s^2, where A is the area and s is the length of a side.

Substituting the value, we get:
A = (3√3/2) x 2^2 = 6√3 units

Therefore, the area of polygon h is 6√3 units.

i. Polygon i is a regular octagon with a side length of 3 units.

The formula for finding the area of a regular octagon is A = 2(1+√2) x s^2, where A is the area and s is the length of a side. Substituting the value, we get:
A = 2(1+√2) x 3^2 = 54 + 36√2 units

Therefore, the area of polygon i is 54 + 36√2 units.

j. Polygon j is a regular pentagon with a side length of 5 units. The formula for finding the area of a regular pentagon is A = (1/4) x √(5(5+2√5)) x s^2, where A is the area and s is the length of a side. Substituting the value, we get:
A = (1/4) x √(5(5+2√5)) x 5^2 ≈ 59.81 units

Therefore, the area of polygon j is approximately 59.81 units.
