Answer:

segment AC is equal to A''B'' over 2

Step-by-step explanation:

Given that,

Scale factor = 2

The coordinates of A is (-3,3)

The coordinates of B is (1,-3)

The coordinates of C is (-3,3)

We know that, the ratio of length of new segment to the length of segment of original figure is called scale factor.

So.

\(\dfrac{A''B''}{AC}=2\\\\\text{On cross multiplying,}\\\\AC=\dfrac{A''B''}{2}\)

It means, segment AC is equal to A''B'' over 2 is the correct answer.

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

When charged electrons (current) are forced through a conducting loop by the weight of an electrical raceway power source, they can perform tasks like lighting a lamp. In a nutshell, voltage equals pressure and is expressed in volts (V).

Here,

The voltage generated by the uv spectrophotometer is inversely proportionate to the amount of light present and linearly proportional to the sample's absorbance.

This indicates that as the sample's absorbance rises, so does the energy the colorimeter generates.

Similar to this, the voltage generated by the colorimeter rises as light strength falls.

The Beer-Lambert Law, which says that a sample's absorbance is directly proportional to its concentration of the absorbing substance and its path length and inversely proportional to incident light intensity, describes this connection.

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

The first four-term of the sequence is found by the given equation \(a_{n-1} = 4a_n\) is given as 144, 36, 9, and 9/4.

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The given radical expression is (√x)^5. To rewrite it in rational exponent form, we need to express the square root (√) as a fractional exponent.

The square root (√) of x can be written as x^(1/2).

To raise x^(1/2) to the power of 5, we can multiply the exponents: (x^(1/2))^5 = x^(5/2).

Therefore, the radical expression (√x)^5 can be rewritten as x^(5/2) in rational exponent form.

In summary, (√x)^5 is equivalent to x^(5/2) in rational exponent form.

The hiker's elevation after 150 minutes is given as follows:

1998.5 feet.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

For this problem, the function is given as follows:

y = 9.01x + 647.

Giving the hiker's elevation after x minutes.

Hence the hiker's elevation after 150 minutes is found with the numeric value at x = 150, replacing the lone instance of x by 150, hence:

y = 9.01(150) + 647 = 1998.5 feet.

Answer:

It changed by 41 people.

Step-by-step explanation:

The numerical coefficient of the 5th term is 560.

The correct answer is option D.

To expand the binomial \((x+2y)^7\), we can use the binomial theorem, which states that the expansion of\((a+b)^n\) can be written as the sum of the terms:

\(C(n,0) * a^n * b^0 + C(n,1) * a^(n-1) * b^1 + C(n,2) * a^(n-2) * b^2 + ... + C(n,r) * a^(n-r) * b^r + ... + C(n,n) * a^0 * b^n\)

where C(n,r) represents the binomial coefficient "n choose r" and is given by the formula: C(n,r) = n! / (r! * (n-r)!).

In the case of\((x+2y)^7\\\), the 5th term corresponds to r=4, and we can calculate the numerical coefficient as follows:

\(C(7,4) * x^(7-4) * (2y)^4\) = C(7,4) * \(x^3 * 2^4 * y^4\)

The binomial coefficient C(7,4) is equal to 35, and the coefficient of the 5th term is obtained by multiplying all the constants: 35 *  \(2^4\)= 560.

Given that Elana sells 3a adult tickets. The number of adult tickets that Elana sells is 15. The question is whether Elana sells at least 100 total tickets.

Elana sells 3a adult tickets, where a is the number of tickets sold. Therefore, the number of adult tickets Elana sells is 3a = 15. Dividing both sides by 3, we geta = 5So, Elana sells 5 adult tickets. To find out whether Elana sells at least 100 tickets, we need to know the number of non-adult tickets sold.

If we assume that all tickets are either adult or non-adult, we can say that the total number of tickets sold is 5 + n, where n is the number of non-adult tickets sold. Since we don't know the value of n, we cannot determine if the total number of tickets sold is at least 100. Thus, the answer to the question is not clear from the information provided.

The subtraction expression as an equivalent addition expression -15 - 12 = (-15) + (-12) = -27.

Equivalent is different from equal. Equal means same in all aspects, whereas equivalent means similar but not identical.

For example, 2 is said to be equal to 2 but equivalent to 1 + 1.

The number that is the “sum” in addition becomes the “minuend” in subtraction. The “addends” in addition become the “subtrahend” and the “difference” in subtraction.

Given that

- 15 - 12

The subtraction expression as an equivalent addition expression.

Then we can rewrite as

(-15) + (-12)

A subtraction problem can be changed into an addition problem because subtracting is the same as adding a negative number. To change a subtraction problem to an addition problem, add the opposite of the number you were subtracting by.

So the answer of the expression is

(-15) + (-12)

-27.

Therefore , The corresponding addition expression for the subtraction statement is (-15) + (-12) = -27.

Answer: 3x+2 and  3x-4 when graphed will be parallel

Step-by-step explanation:

Answer:

x = -1, y = -5

x = 0, y = -3

x = 1, y = -1

x = 2, y = 1

x = 3, y = 5

x = 4, y = 7

These are six sets of integer values that satisfy the inequality |x-y|>2. In each case, the absolute value of the difference between x and y is greater than 2, which satisfies the inequality. For example, in the first set, x = -1 and y = -5, so the absolute value of the difference is |-1 - (-5)| = |-1 + 5| = 6, which is greater than 2. In the second set, x = 0 and y = -3, so the absolute value of the difference is |0 - (-3)| = |0 + 3| = 3, which is greater than 2. Similarly, the other sets of values also satisfy the inequality.

The remaining amount of the substance with the half life of 64.9 days after 100 days is 2.749.

To calculate the amount that remains  after 100 days, this formular can be used

amount remaining = \(a (0.50)^{\frac{t}{h} }\)

where t is the time that was required for the process to take place, where t is 100 days.

h is the halftime, which is been given as 64.9 days

where a is given as the initial amount that is present which is 8.

Then the values can be substituted to have

The standard normal distribution has a mean of 0 and a standard deviation of 1. M ≈ 30.935. The median of the distribution is also 25.

(a) To find M, we first need to convert the given values of mean and standard deviation to the standard normal distribution. This can be done by using the formula Z = (X - μ) / σ, where Z is the Z-score, X is the value of interest, μ is the mean, and σ is the standard deviation. In this case, we have X ~ N(25, 9). Substituting the values into the formula, we get Z = (X - 25) / 3. Now we need to find the Z-score that corresponds to the desired probability of 0.95. Using a standard normal distribution table or a calculator, we find that the Z-score corresponding to a cumulative probability of 0.95 is approximately 1.645. Setting Z equal to 1.645, we can solve for X: (X - 25) / 3 = 1.645. Solving for X, we get X ≈ 30.935. Therefore, M ≈ 30.935.

(b) The median is the value that divides the distribution into two equal halves. In a normal distribution, the median is equal to the mean. In this case, the mean is given as 25. Therefore, the median of the distribution is also 25.

Devaluation of a currency can take place in both absolute and relative terms. When the value of one currency declines in relation to the values of other currencies, this is referred to as a relative devaluation. For instance, the British pound sterling may be worth more today than it did yesterday in terms of US dollars.
