Answer:

Since (2x, x + 17, x + 21, ...) is an arithmetic sequence, we know that the common difference between consecutive terms is constant.

The common difference can be found by subtracting any two consecutive terms in the sequence. Let's subtract the second term (x + 17) from the first term (2x):

2x - (x + 17) = x - 17

Now let's subtract the third term (x + 21) from the second term (x + 17):

(x + 17) - (x + 21) = -4

Since the common difference is constant, we can set the two expressions for the common difference equal to each other:

x - 17 = -4

Solving for x, we get:

x = 13

Therefore, the value of x that makes the sequence (2x, x + 17, x + 21, ...) an arithmetic sequence is x = 13.

The figure is indeed symmetric and the number of lines of symmetry the snowflake has is C. Yes; 6 lines of symmetry.

Generally a snowflake is hexagonal and has 6-way radial symmetry. Thus, one can rotate it 60 degrees (the sixth of full rotation) and it still appears the same.

So, overall, this means that a snowflake holds 6 lines of symmetry which divide it into two identical halves reflecting each other. Consequently, it can be rotated in 60-degree increments and still holds identicality. Akin to this final property, the snowflake artifact possesses six uniquely divided

The value of the variable x in the equation 6 / -4.5 = 8 / 4x is - 3 / 2.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Therefore, let's solve the equation.

The variable in the equation is x . A variable is a number represented with letter in an equation.

Therefore,

6 / -4.5 = 8 / 4x

cross multiply

6(4x) = -4.5(8)

24x = - 36

divide both sides of the equation by 24

Therefore,

x = -36 / 24

We can use the information provided to estimate the number of ducks that have red marks on the bottom.

If only 3 out of 50 people have won a small prize, then we can estimate that the probability of winning a small prize is 3/50 or 0.06. Since the person wins a small prize if there’s a red mark on the bottom of the duck, we can estimate that the proportion of ducks with red marks is also 0.06.

So, we can estimate the number of ducks with red marks as follows:

Number of ducks with red marks = 0.06 x 160

Number of ducks with red marks = 9.6

We can estimate that there are about 9 or 10 ducks with red marks on the bottom.

1.) The average monthly income for Brianna would be = $1,850

2.) The average monthly expenses for Brianna would be =$3,145

3.) The total monthly cash flow = =$ −1,295

The monthly pay check after tax = $1600

The annual scholarship stipend = $3000

That is 3000/12 = $250

Therefore, the average monthly income = 1600+250 = $1,850.

The average monthly expenses = 700+120+75+140+25+110+100+300+250+(12000+1000+1500+800+600/12)

= 1820 + 15900/12

The functions g(x) = -√x - 3 and h(x) = x + 4 meet the requirements, and f(x) = g(h(x)) is true for f(x) = -√(x+4) - 3.

We are given f(x) and we need to find functions g(x) and h(x) such that f(x) = g(h(x)). The given function is f(x) = -√(x+4) - 3.

To find g(x) and h(x), we can split the given function into two simpler functions. Let's first look at the inner function, which deals with the input of the square root. We can define h(x) as the function inside the square root, which is:

h(x) = x + 4

Now we need to find g(x) such that when h(x) is plugged into it, we get the original function f(x). Since we have the square root and a subtraction, we can define g(x) as:

g(x) = -√x - 3

Now let's verify if f(x) = g(h(x)):

g(h(x)) = g(x + 4) = -√(x + 4) - 3

As you can see, g(h(x)) = f(x), which confirms that the functions g(x) and h(x) we found satisfy the condition.

Let x be the length of the shortest side. Then, the length of the second side is 2x, and the length of the third side is x + y, where y is the additional length.

The perimeter of the triangle is the sum of the three sides, so we have:

x + 2x + (x + y) = 60

Simplifying this equation, we get:

4x + y = 60

We also know that the area of a triangle is given by:

A = (1/2)bh

where b is the length of the base, and h is the height. Since the base of the flower bed is the shortest side of length x, we can choose the height to be y. Therefore, we have:

A = (1/2)xy

Now we need to solve for x and y. We can use the equation for the perimeter to solve for y:

y = 60 - 4x

Substituting this into the equation for the area, we have:

A = (1/2)x(60 - 4x)

Simplifying and expanding, we get:

A = 30x - 2x^2

To maximize the area, we can take the derivative of A with respect to x and set it equal to 0:

dA/dx = 30 - 4x = 0

Solving for x, we get:

x = 7.5

Substituting this back into the equation for y, we get:

y = 60 - 4x = 45

Therefore, the dimensions of the flower bed are:

shortest side = x = 7.5 feet second side = 2x = 15 feet third side = x + y = 52.5 feet

Answer: The correct answer is (2,5π/4).

Step-by-step explanation:

The correct polar coordinates of the point (-√2, -√2) are (r, θ) = (2, 5π/4).

Explanation:

Using the formulas for converting Cartesian coordinates to polar coordinates:

r = √(x^2 + y^2)

θ = atan2(y, x)

Plugging in the given values:

r = √((-√2)^2 + (-√2)^2)

= √(2 + 2)

= √4

= 2

θ = atan2(-√2, -√2)

= 5π/4 radians

So, the correct polar coordinates of the point (-√2, -√2) are (r, θ) = (2, 5π/4).

The probability that a person has the virus given that they have tested positive find the P(A/B)=0.0045

We can use Bayes' theorem to find the probability that a person has the virus given that they have tested positive:

P(A | B) = P(B | A) * P(A) / P(B)

where P(B | A) is the probability of testing positive given that the person has the virus, P(A) is the prior probability of a person having the virus (1/300), and P(B) is the total probability of testing positive.

To find P(B), we can use the law of total probability, which states that:

P(B) = P(B | A) * P(A) + P(B | not A) * P(not A)

where P(B | not A) is the probability of testing positive given that the person does not have the virus. This is the false positive rate, which is 5% or 0.05 in this case. P(not A) is the complement of P(A), which is 299/300.

Substituting the values, we get:

P(B) = 0.85 * 1/300 + 0.05 * 299/300

= 0.059

Now we can plug in the values into Bayes' theorem:

P(A | B) = 0.85 * 1/300 / 0.059

= 0.0045 or 0.45%

Therefore, the probability that a person has the virus given that they have tested positive is 0.45% or 0.0045 (rounded to the nearest tenth of a percent).
