Reason: The line goes downhill when moving to the right, and when we're between x = -1 and x = 1. You can think of it like a roller coaster.

Answer:

Sample: Kevin should have used an open circle on 1, not a closed circle. The closed circle means that 1 is included in the solution set, but the inequality is x > 1, so 1 is not part of the solution.

Mistake done by Kelvin is he  used closed circle at 1 where inequality x > 1 which excludes 1.

" Closed circle represents that the value is included in the given range while that of open circle represents given number is not included."

According to the question,

Graph of inequality x > 1 represents all values greater 1 excluding 1.

Number line represents -3 to 5.

A closed circle at 1 means 1 is included.

As per the condition  of inequality x > 1 , 1 is excluded while in closed circle 1 is included both are contradictory conditions.

Hence, mistake done by Kelvin is he  used closed circle at 1 where inequality x > 1 which excludes 1.

In the equation t(78) = 1.03, "p < .01" represents a statistical significance level or the probability of observing the obtained result due to chance alone.

In statistical hypothesis testing, the notation "p < .01" refers to the significance level or the probability threshold used to assess the statistical significance of a result.

In this case, it means that the obtained result, indicated by t(78) = 1.03, is statistically significant at a level of p < .01.

This implies that the likelihood of observing a result as extreme as or more extreme than the obtained result due to chance alone is less than 1%. In other words, the result is unlikely to occur by random variation alone and suggests that there may be a true effect or relationship in the population being studied.

The significance level helps researchers determine whether to accept or reject a null hypothesis based on the strength of evidence provided by the data.

The given mathematical expression is evaluated for the input values (2, 4). The result of the expression is calculated using various operations such as addition, multiplication, square root, natural logarithm, minimum, maximum, and function composition.

The expression f(x1, x2) involves several mathematical operations. Let's evaluate each part of the expression step by step:

1. The first term is 421 + 222, which equals 643.

2. The second term is 3x² + 213. Plugging in x1 = 2 and x2 = 4, we get 3(2)² + 213 = 3(4) + 213 = 12 + 213 = 225.

3. The third term is 5x11². Substituting x1 = 2 and x2 = 4, we have 5(2)(11)² = 5(2)(121) = 1210.

4. The fourth term is (√₁+√₂)². Replacing x1 = 2 and x2 = 4, we obtain (√2 + √4)² = (1 + 2)² = 3² = 9.

5. The fifth term is 10ln(₁). Plugging in x1 = 2, we have 10ln(2) = 10 * 0.69314718 ≈ 6.9314718.

6. The sixth term is (x₁+x₂)(x² + x3). Substituting x1 = 2 and x2 = 4, we get (2 + 4)(2² + 4³) = 6(4 + 64) = 6(68) = 408.

7. The seventh term is min(3r1, 10√2). As we don't have the value of r1, we cannot determine the minimum between 3r1 and 10√2.

8. The eighth term is max{5x1,2r2}. Since we don't know the value of r2, we cannot find the maximum between 5x1 and 2r2.

9. Finally, we have MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2), which are not defined or given.

Considering the given expression, the evaluated terms for the input values (2, 4) are as follows:

- 421 + 222 = 643

- 3x² + 213 = 225

- 5x11² = 1210

- (√₁+√₂)² = 9

- 10ln(₁) ≈ 6.9314718

- (x₁+x₂)(x² + x3) = 408

The terms involving min() and max() cannot be calculated without knowing the values of r1 and r2, respectively. Additionally, MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2) are not defined.

Explanation:

p(-6) = 0 means that plugging x = -6 into p(x) leads to p(x) = 0.

If (x+6) was a factor of p(x), then we can say

p(x) = (x+6)q(x)

where q(x) is some other polynomial. Now let's replace x with -6

p(x) = (x+6)q(x)

p(-6) = (-6+6)q(-6)

p(-6) = 0*q(-6)

p(-6) = 0

The value of q(-6) doesn't matter as multiplying 0 with any number leads to 0.

This is all based on the special case of the remainder theorem that says "if p(k) = 0, then (x-k) is a factor of p(x)".

(x+6) is a factor of p.

The answer is option C.

p(-6) = 0 means that plugging x = -6 into p(x) leads to p(x) = 0.

If (x+6) was a factor of p(x), then we can say

p(x) = (x+6)q(x)

where q(x) is some other polynomial. Now let's replace x with -6

p(x) = (x+6)q(x)

p(-6) = (-6+6)q(-6)

p(-6) = 0*q(-6)

p(-6) = 0

The value of q(-6) doesn't matter as multiplying 0 with any number leads to 0.

Answer:

42 divided by 6=7 so 7 hrs

Step-by-step explanation:

its probalay wrong im not smart lol

Let f(x) be her earnings for x hours. it's given that \(f(x) = 6x\). The question asks what is x for \(f(x) = 42\).

\(42 = f(x) \\~\\42 = 6x \\~\\x = 7\)

She has to work 7 hours.

Sheena will reach the opposite bank approximately 11.269 miles downstream from her starting point.

To determine how far upstream or downstream Sheena will reach the opposite bank, we can use the concept of vector addition.

Let's analyze the situation:

Sheena's boat speed in still water is 2.30 mi/h.

The river width is 1.20 mi.

The current is flowing at a speed of 1.60 mi/h.

To go straight across the river, Sheena needs to balance the current by heading upstream at an angle that compensates for the downstream drift caused by the current.

Let's calculate the time it takes for Sheena to cross the river at an angle of 25.0 degrees upstream:

First, we calculate the effective downstream speed caused by the current:

Effective downstream speed = Current speed = 1.60 mi/h.

Then, we calculate the effective upstream speed required to counteract the current:

Effective upstream speed = Boat speed in still water * sin(angle)

= 2.30 mi/h * sin(25.0 degrees)

≈ 0.976 mi/h.

Now, we can calculate the time it takes to cross the river:

Time = River width / (Effective upstream speed - Effective downstream speed)

= 1.20 mi / (0.976 mi/h - 1.60 mi/h)

≈ 7.043 hours.

Since Sheena's boat speed is slower than the current speed, she will not be able to reach the opposite bank directly. She will be carried downstream by the current, and the distance downstream can be calculated as:

Distance downstream = Effective downstream speed * Time

= 1.60 mi/h * 7.043 hours

≈ 11.269 mi.

Therefore, Sheena will reach the opposite bank approximately 11.269 miles downstream from her starting point.

The minimum number of $5-notes she has is 11.

To find the minimum number of $5-notes that Siti has, we need to consider the maximum number of $2-notes she can have while still having a total value of more than $132.

Let's assume Siti has x $5-notes. Since the total value of all the notes is more than $132, we can set up the following equation:

5x + 2(50 - x) > 132

Simplifying the equation:

5x + 100 - 2x > 132

Combining like terms:

3x + 100 > 132

Subtracting 100 from both sides:

3x > 32

Dividing both sides by 3:

x > 10.67

Since x represents the number of $5-notes, it must be a whole number. Therefore, Siti must have at least 11 $5-notes in order for the total value of the notes to be more than $132.

Answer:

The third figure from the top.

To calculate the monthly principal + interest payments for a house with a down payment and a mortgage using an Excel formula, you can use the PMT function. Here's how:

Calculate the loan amount by subtracting the down payment from the house cost. In this case, the down payment is 25% of $300,000, so it would be $75,000.
  Loan Amount = $300,000 - $75,000 = $225,000    

Determine the monthly interest rate by dividing the annual interest rate by 12. In this case, the annual interest rate is 2.75%, so the monthly interest rate would be 2.75% / 12 = 0.00229.

Determine the loan term in months. Since it's a 30-year mortgage, the loan term would be 30 * 12 = 360 months.

Use the PMT function in Excel to calculate the monthly principal + interest payment.
  Monthly Payment = -PMT(0.00229, 360, 225000)

The negative sign is used because the payment is an outgoing cash flow.

By using this formula in Excel, you can find the monthly principal + interest payments for your mortgage. Remember to adjust the interest rate, loan amount, and loan term if they differ from the example provided.

To calculate the monthly principal + interest payments using an Excel formula, you can use the PMT function by inputting the appropriate parameters: the monthly interest rate, loan term in months, and loan amount.

For team A to win the best-of-five series over team B, team A must win at least three of the five games played, and the last game played must be a win for team A. Let's consider the different ways that team A can win the series:

Team A wins the first three games and loses the last two games.

Team A wins the first two games, loses the third game, wins the fourth game, and loses the fifth game.

Team A wins the first two games, loses the third game, loses the fourth game, and wins the fifth game.

Team A wins the first game, loses the second game, wins the third game, loses the fourth game, and wins the fifth game.

The probability of each of these outcomes is:

(1/3)^3 * (2/3)^2 = 8/243

(1/3)^2 * (2/3) * (1/3) * (2/3) = 8/243

(1/3)^2 * (2/3) * (2/3) * (1/3) = 8/243

(1/3) * (2/3) * (1/3) * (2/3) * (1/3) = 8/243

Therefore, the probability that team A wins the best-of-five series over team B is the sum of these probabilities:

P(A wins series) = 8/243 + 8/243 + 8/243 + 8/243 = 32/243
