To match the equations in Column I with the correct first step for solving them in Column II, we need to identify the appropriate algebraic manipulation for each equation.

Equation (a) is 2x + 3 = 5. The correct first step for solving this equation is to subtract 3 from both sides to isolate the term with x, resulting in 2x = 2.

Equation (b) is √(x + 5) = 9. The correct first step for solving this equation is to square both sides of the equation, eliminating the square root, resulting in x + 5 = 81.

Equation (c) is (x + 5)^(5/2) = 32^(2/3). The correct first step for solving this equation is to raise both sides of the equation to the power 2/3, resulting in (x + 5)^(5/2)^(2/3) = 32.

Equation (d) is (x + 5)^(-6) = 0. The correct first step for solving this equation is to take the reciprocal of both sides, resulting in 1/(x + 5)^6 = 0.

Equation (e) is √(x(x + 5)) = -6. The correct first step for solving this equation is to square both sides of the equation, eliminating the square root, resulting in x(x + 5) = 36.

Matching the equations with their correct first steps:

(a) - Subtract 3 from both sides

(b) - Square both sides

(c) - Raise both sides to the power 2/3

(d) - Take the reciprocal of both sides

(e) - Square both sides

Answer:

  $48,000 to start, with 6% raises

Step-by-step explanation:

The starting salaries are within a few percentage points of each other, so the majority of the difference in earnings will come because of the raises. The offer with the largest raise percentage is likely the best.

The earnings total can be figured as the sum of a geometric series with a first term of "starting salary" and a growth factor of (1+raise percentage). For starting salary 's' and raise percentage 'r', the total earnings in 6 years will be ...

  S = s((1+r)^6 -1)/r

Here are the total earnings, in thousands, for each of the offers:

  a) s = 49, r = .03, S = 316.95

  b) s = 51, r = .01, S = 313.75

  c) s = 48, r = .06, S = 334.82 . . . . best offer

So, the simpler form of the radical expression 4 sqrt 1296 x^16y^12 is 144x^14y^14 sqrt (x) sqrt (y).

To simplify the radical expression 4 sqrt 1296 x^16y^12, we need to first factor the number inside the radical. 1296 can be factored into 36 x 36, which simplifies to 6^4. So, the expression becomes 4 sqrt (6^4 x^16y^12).
Next, we can simplify the expression further by using the property of exponents that says a^m x a^n = a^(m+n). This means that we can combine the exponents of x and y, which gives us 4 sqrt (6^4 x^(16+12) y^(12+16)). Simplifying this, we get 4 sqrt (6^4 x^28 y^28).
Now, we can simplify the radical expression even further by using the property that says sqrt (a x b) = sqrt (a) x sqrt (b). Applying this to our expression, we get 4 x 6^2 x sqrt (x^28) x sqrt (y^28). Simplifying this further, we get 144x^14y^14 sqrt (x) sqrt (y).

Step-by-step explanation:

180-112 = 68

just simple angle addition

crossin my fingers and hoping this helps

The measure of the reference angle for a 122° angle is 68°.

Reference number associated with t is defined as the shortest distance from the x axis to the terminal point t, along a unit circle.

So we have to find the shortest angle that the X axis make with the angle 112 degree.

112 degree lies on the second quadrant.

We know that,

Sum of the angles along the X axis = 180°

Reference angle of 112 degree = 180° - 112°

The worker's daily metabolic rate is approximately 2169.28 kcal.

To calculate the worker's daily metabolic rate, we need to consider the energy expenditure during working hours and non-working hours.

Energy expenditure during working hours:

The worker's average energy expenditure rate during working hours is 5 kcal/min.

The worker works for 41.85 minutes per hour.

So, the energy expenditure during working hours is 5 kcal/min * 41.85 min = 209.25 kcal/hour.

Energy expenditure during non-working hours:

The worker's average energy expenditure rate during non-working hours is 1.7 kcal/min.

The worker has a rest time of 18.15 minutes per hour.

So, the energy expenditure during non-working hours is 1.7 kcal/min * 18.15 min = 30.955 kcal/hour.

Total daily metabolic rate:

The worker works for 8 hours per day (assuming a standard workday).

So, the total energy expenditure during working hours is 209.25 kcal/hour * 8 hours = 1674 kcal.

The remaining non-working hours in a day are 16 hours (24 hours - 8 hours).

So, the total energy expenditure during non-working hours is 30.955 kcal/hour * 16 hours = 495.28 kcal.

The daily metabolic rate is the sum of the energy expenditure during working hours and non-working hours:

Daily metabolic rate = Energy expenditure during working hours + Energy expenditure during non-working hours

Daily metabolic rate = 1674 kcal + 495.28 kcal = 2169.28 kcal.

Answer:

S = 32.1 m/s

Step-by-step explanation:

P = 1,500

S = 30

since P is proportional to S², then we must first determine S² = 900

900 / 1,500 = S² / 1,715

(900 x 1,715) / 1,500 = S²

1,543,500 / 1,500 = S²

S² = 1,029

S = √1,029 = 32.08 m/s ≈ 32.1 m/s

The correct sampling method described in the question is a stratified random sample among the simple random sample,  stratified random sample, cluster random sample and  Voluntary random sample

The sampling method described in the question is a stratified random sample.

In a stratified random sample, the population is divided into subgroups or strata based on certain characteristics or criteria. Then, a random sample is selected from each stratum. The key idea behind this method is to ensure that each subgroup is represented in the sample proportionally to its size or importance in the population. This helps to provide a more accurate representation of the entire population.

In the given sampling method, the population is divided into subgroups, and a fixed number of units is taken from each group. This aligns with the process of a stratified random sample. The sample selection is random within each subgroup, but the number of units taken from each group is fixed.

Other sampling methods mentioned in the question are:

Simple random sample: In a simple random sample, each unit in the population has an equal chance of being selected. This method does not involve dividing the population into subgroups.

Cluster random sample: In a cluster random sample, the population is divided into clusters or groups, and a random selection of clusters is included in the sample. Within the selected clusters, all units are included in the sample.

Voluntary random sample: In a voluntary random sample, individuals self-select to participate in the sample. This method can introduce bias as those who choose to participate may have different characteristics than those who do not.

Therefore, the correct sampling method described in the question is a stratified random sample.

Answer:

2^0

Step-by-step explanation:

When you are dividing 2 exponents with the same base (in this case, 2) you subtract them. 2^5 ➗ 2^5 => 2^(5-5) = 2^0 => which is equal to 1, but the answer here would be 2^0.

There are two ways to go about this problem.

The first way, the generic way, is to know that,

\(\frac{a^n}{a^m}=a^{n-m},a\neq0\).

So,

\(\frac{2^5}{2^5}=2^{5-5}=\boxed{2^0}\).

The second way is to realise that both numerator and denominator are equal and when diving two equal numbers you obtain 1. (except when diving zeros) aka,

\(\frac{a}{a}=1, a\neq0\)

And 1 equals to any number raised to the power of zero,

\(a^0=1,a\neq0\)

So we just have to say that the 1 we got is rewritten as some base to the power of zero.

Since our base needs to be 2, we just simply say,

\(2^0\).

A U.S. dollar can buy approximately 0.21 Swiss francs (rounded to two decimal places). Thus, the answer is option d) 0.21.

To determine how much Swiss francs a U.S. dollar can buy, we need to use the given exchange rates between different currencies.

Given:

1 ounce of gold costs 15 U.S. dollars and 14.3028 Italian lira.

1 ounce of silver costs 0.7302 Italian lira and 0.1605 Swiss francs.

Let's calculate the exchange rate between the U.S. dollar and the Swiss franc using the given information:

1 ounce of silver = 0.7302 Italian lira

1 ounce of silver = 0.1605 Swiss francs

To find the exchange rate between the Italian lira and the Swiss franc, we can divide the price of 1 ounce of silver in Swiss francs by the price of 1 ounce of silver in Italian lira:

Exchange rate: 0.1605 Swiss francs / 0.7302 Italian lira

Simplifying this, we get:

Exchange rate: 0.2199 Swiss francs / 1 Italian lira

Now, let's find the exchange rate between the U.S. dollar and the Italian lira:

1 ounce of gold = 15 U.S. dollars

1 ounce of gold = 14.3028 Italian lira

To find the exchange rate between the U.S. dollar and the Italian lira, we can divide the price of 1 ounce of gold in Italian lira by the price of 1 ounce of gold in U.S. dollars:

Exchange rate: 14.3028 Italian lira / 15 U.S. dollars

Simplifying this, we get:

Exchange rate: 0.9535 Italian lira / 1 U.S. dollar

Finally, to find how much Swiss francs a U.S. dollar can buy, we multiply the exchange rate between the U.S. dollar and the Italian lira by the exchange rate between the Italian lira and the Swiss franc:

Exchange rate: 0.9535 Italian lira / 1 U.S. dollar * 0.2199 Swiss francs / 1 Italian lira

Simplifying this, we get:

Exchange rate: 0.2099 Swiss francs / 1 U.S. dollar

Therefore, a U.S. dollar can buy approximately 0.21 Swiss francs (rounded to two decimal places). Thus, the answer is option d) 0.21.

The basis for the vector space of polynomials of degree at most two which satisfy the constraint is {1 - 2x - 3x²}.

A basis for the vector space of polynomials of degree at most two which satisfy the constraint is {1 - 2x - 3x²}.To find a basis for the vector space of polynomials of degree at most two which satisfy the constraint, we use the following steps:Step 1: We let p(x) = a + bx + cx² and substitute it into the given constraint. That is,p(1) - 3p(0) + 2p(−1) = 0Thus, we get a + b + c − 3a = 0 and a − 2b + c = 0.

These equations can be rewritten as4a − b − c = 0 and a − 2b + c = 0.Step 2: We can solve for a, b, and c by setting up an augmented matrix as shown below:4 −1 −1 | 00 1 −2 | 0Using row reduction, we get the augmented matrix in row echelon form as follows:4 −1 −1 | 00 1 −2 | 0R2 → R2 + 2R1 −> 0 −1 −3 | 00 1 −2 | 0R1 → R1 + R2 -> 4 0 −4 | 00 1 −2 | 0R3 → R3 / (-4) -> 0 0 1 | 0R2 → R2 + 3R3 -> 0 1 0 | 0R1 → R1 + R3 -> 4 0 0 | 0

Therefore, the solution is a = 0, b = 0, and c = 0.Since the only polynomial of degree at most two that satisfies the constraint is the zero polynomial, the vector space of polynomials of degree at most two which satisfy the constraint is a trivial vector space, denoted by {0} Since the dimension of a trivial vector space is 0, then any set containing only the zero vector is a basis for the vector space.

Therefore, the basis for the vector space of polynomials of degree at most two which satisfy the constraint is {0}.Step 5: However, the question is asking for a basis for the vector space of polynomials of degree at most two which satisfy the constraint. Therefore, we need to redo the calculations to account for the fact that there is no nontrivial vector in the vector space of polynomials of degree at most two which satisfy the constraint.

In this case, we can take any non-zero vector as the basis for the vector space of polynomials of degree at most two which satisfy the constraint. For example, we can take p(x) = 1 - 2x - 3x² as the basis. Since p(x) is a polynomial of degree at most two, and it satisfies the constraint p(1) - 3p(0) + 2p(−1) = 0, then it is in the vector space of polynomials of degree at most two which satisfy the constraint. Therefore, the basis for the vector space of polynomials of degree at most two which satisfy the constraint is {1 - 2x - 3x²}.

The correct answer is Point A onto Point D, and AB onto DE.

Since the triangles are congruent, we know that they have the same shape and size. Therefore, we need to find a sequence of rigid motions that will map one triangle onto the other.

The first step is to map point A onto point D, which can be done with a translation. The second step is to map AB onto DE, which can be done with a rotation about point D. This sequence of rigid motions will map triangle ABC onto triangle DEF.

An even function, then, is symmetric about the y-axis. The graph of an even function would look geometrically identical to its reflection across the y- axis if we were to plot it. The functions f(x) = x2, f(x) = cos(x), and f(x) = |x| are examples of even functions.

An odd function, then, is symmetric about the origin. If we were to draw the graph of an odd function geometrically, if we were to plot the graph of an odd function, it would appear to be identical to its reflection across the origin, after being rotated 180 degrees. Some examples of odd functions include f(x) = x³, f(x) = sin(x), and f(x) = 1/x.
