Sarah's final position would be negative. Therefore, option B is the correct answer.

Given that, Sarah starts at a positive position along the x-axis. She then undergoes a negative displacement.

A negative displacement means that Sarah has moved backward along the x-axis, so her final position would be negative.

Therefore, option B is the correct answer.

S - a randomly chosen pregnancy result in a successful delivery

C - a randomly chosen pregnancy ending in a C section

Brent’s after-school game club has 12 members from which a six-member team is created. The correct option is b.

Brent’s club has more possible team combinations because there are more members to choose from.

To find out which student's club has more possible combinations for their six-member team, we need to find the total

number of combinations that can be created in each club.

To do this, we will use the formula for combinations, which is:

nCk = n! / k! (n - k)!

where n is the total number of

members in the club, and

k is the number of members in the team.

Let's start by finding the number of combinations

that can be created in Brent's club:

nCk = 12C6 = 12! / 6! (12 - 6)! = 924

Next, let's find the number of combinations that

can be created in Miguel's club:

nCk = 10C6 = 10! / 6! (10 - 6)! = 210

Since 924 is greater than 210, we can see that

Brent’s club has more possible team combinations because there are more members to choose from. Therefore,

option b is correct.

The solutions to the equation are x= -9 and x = 6

From the information given, we have that;

|x2 + 9x| = 6x + 54

To solve the quadratic equation, collect the like terms, we have;

x² + 9x - 6x = 54

subtract the terms

x² + 3x = 54

Put in standard form

x² + 3x - 54 = 0

Find the pair factors of -54 that add up to give 3 and substitute the values

x² + 9x - 6x - 54 = 0

group in pairs

(x² + 9x) - (6x - 54) = 0

factorize the expressions

x(x + 9) - 6(x + 9) = 0

Then, we have;

x- 6 = 0

x = 6

x + 9 = 0

x = -9

A, b and c can do a piece of work in 24, 30 and 40 days respectively. the work is completed in 13 days.

Let's calculate the work done by each person per day:

A completes 1/24 of the work per day.

B completes 1/30 of the work per day.

C completes 1/40 of the work per day.

Let's assume the total work is represented by "W".

When all three, A, B, and C, work together, their combined work rate per day is:

1/24 + 1/30 + 1/40 = (5 + 4 + 3) / 120 = 12/120 = 1/10

This means that when all three work together, they complete 1/10 of the total work per day.

Now, let's calculate the number of days it takes for them to complete the work. Let's represent this number of days by "D".

Since C leaves 4 days before the completion of the work, the remaining work is 1 - 1/10 = 9/10.

We can set up the equation:

(D - 4) * (1/10) = 9/10

Simplifying the equation:

D - 4 = 9

D = 9 + 4

D = 13

Therefore, the work is completed in 13 days.

The correct number of significant digits in a measurement depends on the precision of the measuring instrument and the certainty of the measurement.

The number of significant digits in a measurement indicates the precision and accuracy of the measurement. Significant digits are the digits that carry meaning and contribute to the overall precision of the measurement. The rules for determining the correct number of significant digits are as follows:

1. Non-zero digits are always significant. For example, in the number 123.45, all the digits (1, 2, 3, 4, and 5) are significant.

2. Zeroes between non-zero digits are also significant. For example, in the number 1.003, all the digits (1, 0, 0, and 3) are significant.

3. Leading zeroes (zeros to the left of the first non-zero digit) are not significant. For example, in the number 0.0056, the significant digits are 5 and 6.

4. Trailing zeroes (zeros to the right of the last non-zero digit) are significant if they are after a decimal point or if they have been measured. For example, in the number 1.00, all the digits (1, 0, 0) are significant.

It is important to report the correct number of significant digits in a measurement to convey the precision and accuracy of the data. Failing to do so may result in misleading or incorrect interpretations of the results.

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Let r represent the number of reserved seats and g represent the number of seats for general  admission.

Since the school has 1,200 concert tickets for sale, hence:

r + g ≤ 1200   (1)

Also, there are at most 500 reserved-seat tickets. Hence:

Answer:

\(\huge\boxed{Q = 110 \textdegree, \ ST = 9 \ \text{ft}}\)

Step-by-step explanation:

When we reflect and transform a figure, the angle lengths nor the side lengths are touched. The side length only changes if we dilate or stretch the figure, and the angle length only changes if we stretch the figure.

Therefore, we know the information is going to be the exact same. We just have to figure out what corresponds to what from JKLM to QTSR.

If we reflect a figure across a horizontal reflection line through its center, the figure will just flip sides. M will be J, L will be K, etc.

When we translate this down, nothing changes except its position. So we can pretend these two shapes are right on top of each other for now.

When we move these right on top of each other, we can see that Angle J overlaps with Angle Q. Since they don't have any weird intersects, we know that angle J will be equal to Angle Q. Since we already know J is 110°, we know Q is also 110°.

When we move it on top, we also see that KL overlaps with ST perfectly. Since we know KL is 9, that must mean ST is also 9.

The downstream speed is the sum of the canoe speed and the stream speed:

  6 = c + s

The upstream speed is the difference of the canoe speed and the stream speed:

  2 = c - s

Adding these two equations, we get ...

  8 = 2c

  4 = c . . . . . divide by 2

The canoe speed in still water is 4 miles per hour.

Answer:

4 Miles an hour

Step-by-step explanation:

The improper fraction can be written as:

44/7

An improper fraction is a fraction where the numerator is larger than the denominator.

Here we want to write.

6 + 2/7 as an improper fraction, to do so, we just need to write 6 as a fraction with a denominator of 7 and then add them.

We know that:

6 = 6*(7/7) = 42/7

Then we can write:

6 + 2/7 = 42/7 + 2/7 = 44/7

That is the improper fraction.

The function is not normalizable and cannot be a wave function.

A wave function must satisfy two important conditions. First, it must be normalizable, meaning its integral over all space is finite.

Second, it must be single-valued and continuous.

(i) The function Ψ1​(x) = \(e^{-x^{5} }\) is acceptable as a wave function, since it is continuous everywhere and decays to zero as x → ±∞.

However, we must check if it is normalizable. The normalization condition for a one-dimensional wave function Ψ(x) is:

∫(-∞) to ∞ |Ψ(x)|²dx = 1

In this case, we have:

∫(-∞) to ∞ |Ψ₁(x)|² dx

= ∫(-∞) to ∞ \(e^{-2x^{5} }\) dx

This integral can be quite challenging to evaluate, but we can see that the integrand goes to zero faster than any power of x as x → ±∞.

Therefore, the integral is convergent and the function is normalizable.

Therefore, Ψ₁(x) is an acceptable wave function.

(ii) The function Ψ₂​(x) = cos(x - 2π/3) is not acceptable as a wave function, since it is not normalizable.

The normalization condition for a one-dimensional wave function Ψ(x) is:

∫( -∞) to ∞ |Ψ(x)|² dx = 1

In this case, we have:

∫(-∞) to ∞ |Ψ₂​(x)|² dx = ∫(-∞)to∞ cos²(x - 2π/3) dx

This integral is not convergent, since the integrand oscillates between 0 and 1 over an infinitely repeating interval.

Therefore, the function is not normalizable and cannot be a wave function.
