Therefore, the total distance Gabe will paddle is 2x + 400 meters. The exact value of x depends on the width of the river, which is not provided in the given information.

To find the total distance Gabe will paddle, we need to consider the distance he will travel from Q to P, then from P to R, and finally from R back to Q.

First, let's consider the distance from Q to P. Since Gabe will paddle in a diagonal line across the river, this distance can be calculated using the Pythagorean theorem.

The length of the bridge (PR) is given as 400 meters, which is the hypotenuse of a right triangle. The width of the river can be considered as the perpendicular side, and the distance Gabe will paddle from Q to P is the other side. Let's call this distance x.

Using the Pythagorean theorem, we have:

x^2 + (width of the river)^2 = PR^2

Since the width of the river is not given, we'll represent it as w. Therefore:

x^2 + w^2 = 400^2

Next, let's consider the distance from P to R. Gabe will paddle along a route beside the bridge, which means he will travel the length of the bridge (PR) again. So, the distance from P to R is also 400 meters.

Finally, Gabe will paddle back from R to Q along the shore. Since he will follow the shoreline, the distance he will paddle is equal to the distance from Q to P, which is x.

To find the total distance, we add up the distances:

Total distance = QP + PR + RQ

= x + 400 + x

= 2x + 400

Therefore , the solution of the given problem of circle comes out to be

n =4 for the length of chord.

Each spot that is a certain distance from that other point in the plane forms a circle (center). As a result, it is a curve composed of vertices that are isolated from one another in the plane by a specific distance. Furthermore, it is axis of rotation symmetric about the center at all angles. The circle's enclosed, two-dimensional plane has every pair of endpoints uniformly separated from the "center." Draw a line thru the circle to create a circular symmetry line. Additionally, at every angle, it rotates equally about the center.

Here,

Given :

2 cords AB & CD can intersect at point P,

according to the following theorem:

|AP| |PB| = |CP| |PD|

We obtain

=>(n-2) x 16 = 8x (n+8)

using the theory of intersection between two cords.

Use the following formula:

=>16n+32 = 8n +64

=>8n -32 = 0

=>8n=32.

8 divided by both sides.

n = 32/8

n = 4

Consequently, n has a value of 4.

Isosceles triangle is the triangle in which two sides of the triangle are congruent.The altitude from the top of an isosceles triangle bisects the base into two equal parts. The value of side FC is 12.

Given-

In triangle ADE side AE and the side DE are congruent.

The other side AD is the base of the triangle.

The triangle ADE is the isosceles triangle. For the isosceles triangle we know that the two sides are equal. In triangle ADE side AE and the side DE are congruent. the other side AD is the base of the triangle. The altitude form the top of an isosceles triangle bisects the base into two equal parts. thus the value of CD and AC is equal. Thus,

\(AC=CD\)

In the question the value of CD is twelve units. Thus,

\(AC=12\)

Hence the side AC is 12 units.

Now in triangle ABC side AB and the side BC are congruent.

The other side AC is the base of the triangle. The altitude form the top of an  triangle ABC bisects the base AC into two equal. FC are 1/2 of the side AC. therefore,

\(FC=\dfrac{AC}{2}\)

\(FC=\dfrac{12}{2}\)

\(FC=6\)

Hence, the value of side FC is 12 units.

Answer:

\(m\angle V = 156\textdegree\)

Step-by-step explanation:

First, we can solve for x using the fact that opposite interior angles of a parallelogram are congruent (and therefore their measures are equal).

m∠Y = m∠W

↓ plugging in the given values

10x - 27 = 2x + 29

↓ subtracting 2x from both sides

8x - 27 = 29

↓ adding 27 to both sides

8x = 29 + 27

↓ simplifying

8x = 56

↓ divide both sides by 8

x = 7

Now, we can find the m∠Y:

m∠Y = (10x - 27)°

m∠Y = 10(7)° - 27°

m∠Y = 70° - 27°

m∠Y = 42°

m∠W = m∠Y = 42°

Using m∠Y and m∠W, we can solve for m∠V and m∠X because we know that they are also congruent.

\(m\angle V = \dfrac{360\textdegree - 2(42\textdegree)}{2}\)

\(m\angle V = \left(\dfrac{312}{2}\right)\textdegree\)

\(\boxed{m\angle V = 156\textdegree}\)

(a) h(x) is the input for g(x).

(b) For x = 6 in h(g(x)), the final output will be -5.h(x) is the input for g(x).

(a) Angelina has two machines and she has to arrange them in order so that the output of one becomes the input of the other function machine. She is using a beginning input of 6.

g(h(x)) = \(\sqrt{x^2 - 6 -5}\)

= \(\sqrt{x^2 - 11}\)

g(h(6)) = \(\sqrt{6^2 - 11}\)

g(h(6) = \(\sqrt{36 - 11}\)

= \(\sqrt{25}\) = 5

We get the output as 5. Therefore, to get the final output of 5, the machines will be put in the order g(h(x)). If she uses the beginning input of 6, she will have to give this input to machine h(x) first, and then h(x) will be given as an input to machine g(x).

(b) It is not possible for g(h(x)) = \(\sqrt{x^2 - 11}\) to give an output of -5, because its value will always be non-negative for any x. Now, let's see h(g(x)).

h(g(x)) = \((\sqrt{x - 5})^2\) - 6

= x - 5 - 6

= x - 11

The result will be a non-constant linear function, so its value can be any real number, which means it can be -5 as well including -5. To see at what value of x, this will give an output of -5, we will equate this to -5.

x - 11 = -5

x = 6

To calculate P(A and B), you need to use the formula for the probability of two events occurring together.

The formula is:

P(A and B) = P(A) x P(B | A) Where P(A) is the probability of event A occurring, and P(B | A) is the probability of event B occurring given that event A has already occurred.

1. Determine the probability of event A occurring. This will be your P(A) value.

2. Determine the probability of event B occurring given that event A has already occurred. This will be your P(B | A) value.

3. Multiply P(A) and P(B | A) together to get P(A and B). For example, let's say that event A is rolling a 6 on a six-sided die, and event B is flipping a coin and getting heads. The probability of event A occurring is 1/6, and the probability of event B occurring given that event A has already occurred is 1/2.

So:

P(A and B) = P(A) x P(B | A) P(A and B) = (1/6) x (1/2) P(A and B) = 1/12

So the probability of both events occurring together is 1/12.

1. The value 550 represents the initial balance in the account, which means the account started with $550.

2. 528.28

425.00 x  2.7% x 9 = 103.275

Then we add 103.275 to the initial deposit of $425.00

425.00 + 103.275 = 528.275

Therefore the answer is $528.28

3. The answer for this one is  f(n) = 56 + 3(n − 1)

So, as we can see the first value is 56 and the common difference is 3 and the rule for the nth term is \(a_{n} =a_{1} +d(n-1)\)

Therefore, its 56 + 3(n − 1)

4. For this one we solve for r and using a calculator its r = 0.04

The value of r from the given equation is 0.04. Therefore, option A is the correct answer.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

1) The given equation is 687.5=550(1+0.05t)

Here, amount=$687.5, principal (initial balance)=$550 and rate of interest =0.05×100 =5%

So, the value 550 represents the initial balance in the account, which means the account started with $550.

2) Given that, principal=$425.00, time period=9 years and rate of interest=2.7%

We know that, S.I=(P×T×R)/100

= (425×9×2.7)/100

= 103.275

Amount=103.275+425

= 528.275

≈ $528.28

3) The given arithmetic sequence is 56, 59, 62, 65, 68,.…

Here, first term (a)=56 and common difference=59-56=3

We know that, general form of arithmetic sequence is aₙ=a+(n-1)d

Now, f(n)=56+(n-1)3

4) The given equation is 816=600(1+9r)

1+9r =816/600

1+9r =1.36
