−3(n + 9) = 3
The solution is n = ______.

Answer:

15mph

Step-by-step explanation:

360 divide by 3 =  120

360 divide by 4 = 90

120 - 90 = 30

30 divide by 2 (cause boosting speed and drag) = 15

so let's check

120-15=105

105+15=120

105-15= 90

so the answer's 15.

To find the effect of the wind and the average speed of the aircraft, set up a system of equations and solve them simultaneously. The effect of the wind is a speed of 15 mph and the average speed of the aircraft is 105 mph.

To find the effect of the wind and the average speed of the aircraft, we can set up a system of equations. Let's denote the speed of the aircraft as 'a' and the speed of the wind as 'w'. With a tailwind, the aircraft can fly 360 miles in 3 hours, so we have the equation 360 = (a + w) * 3. Against the wind, the aircraft can fly the same distance in 4 hours, so we have the equation 360 = (a - w) * 4.

Now, we can solve these equations simultaneously to find the values of 'a' and 'w'. Multiplying the first equation by 4 and the second equation by 3 gives us 1440 = (a + w) * 12 and 1080 = (a - w) * 12. Subtracting the second equation from the first equation eliminates the 'w' term, giving us 1440 - 1080 = (a + w) * 12 - (a - w) * 12. Simplifying further, we get 360 = 24w. Dividing both sides by 24 gives us w = 15. Substituting this value back into one of the original equations, we can find the value of 'a'. Using the equation 360 = (a + 15) * 3, we can solve for 'a' to get a = 105.

Therefore, the effect of the wind is a speed of 15 mph and the average speed of the aircraft is 105 mph.

The answer is a, rohan is the most important character who opposes Ethane.

Step-by-step explanation:

The requried, it is likely that the statement "Rohan is the most important character who opposes Ethane" is the most accurate reason for Rohan being the protagonist of "The Catch."  Option A is correct

This statement suggests that Rohan plays a central role in the story and is positioned as the primary character in opposition to Ethane.

The other statements, such as Rohan being helped by Lewess and the moral evaluation of Rohan and Ethane's characters, do not necessarily establish Rohan as the protagonist but provide additional details about his relationships and qualities within the story.

The fact that Rohan is the first character described in the story does not directly determine his status as the protagonist but may indicate his significance in the narrative.

Final answer:

Roberta will jog 13 laps on the sixth day of her jogging routine, following the arithmetic sequence of adding 2 laps each day, starting with 3 laps on the first day.

Explanation:

The student is asking about a pattern in which Roberta jogs an increasing number of laps each day, with the sequence starting at 3 laps and increasing by 2 laps each subsequent day. To determine on which day Roberta will jog 13 laps, we can identify this as an arithmetic sequence with a common difference of 2. The first day is 3 laps, the second day is 5 laps, and this pattern continues. Following this sequence, the number of laps jogged by Roberta each day is:

Thus, Roberta will jog 13 laps on the sixth day, if the pattern continues.

- 5 < x

Step-by-step explanation:

To solve, we need to isolate the variable: x

5x - 7 < 8x + 8

Subtract 5x from both sides

5x -  5x -7 < 8x -5x + 8

- 7 < 3x + 8

Subtract 8 from both sides

- 7 -8 < 3x + 8 -8

-15< 3x

Divide both sides by 3

Answer:

Answer:

The values of x that satisfy the given equation are:

x1 = 1.183 + nπ

x2 = -1.183 + nπ

Step-by-step explanation:

Given tan²x - sin²x/sin²x = 5

Simplifying this, we have

tan²x - 1 = 5

Adding 1 to both sides, we have

tan²x = 6

Because tan²x = (tanx)², we can write as

(tanx)² = 6

Taking square roots of both sides, we have.

tanx = ±√6

x = arctan(±√6) + nπ

≈ 1.183 + nπ or -1.183 + nπ

The question asks to find a trigonometric value for x given a trigonometric equation. Clear solution steps cannot be provided due to ambiguity in the equation's presentation. Normally, one would use trigonometric identities or methods like Newton's method to find x.

The question requires us to find a numerical value of one trigonometric function of x given the equation tan2x - sin2x/sin2x = 5. Although the provided reference text contains various trigonometric contexts, it lacks direct relation to solving the given equation.

In order to solve for x, one would typically aim to manipulate the equation into a standard trigonometric identity or apply techniques such as Newton's method if handling a more complex algebraic expression involving trigonometric functions.

To tackle the given trigonometric equation, we would ideally express tan2x in terms of sin2x and cos2x using the identity tan2x = sin2x/cos2x, thus simplifying the equation and allowing us to isolate and solve for x.

Unfortunately, there is an ambiguity in the equation presented in the question (lack of clear parentheses), and so a definitive solution cannot be provided without clarification.

To find :

The height of the tree.

We can use the sine to calculate the height of the tree.

sin 25° = t/34.5

sin 25° = 0.42

sin 25° = t/34.5

0.42 = t/34.5

Answer:

12y + 5x = 169

Step-by-step explanation:

Differentiate wrt x

2x + 2y(dy/dx) = 0

dy/dx = -x/y

At (5,12)

m = -5/12

y = (-5/12)x + c

12 = -25/12 + c

c = 169/12

y = (-5/12)x + 169/12

12y + 5x = 169

Answer:

y = [tex]\frac{-5}{12}[/tex] x +17

Step-by-step explanation:

We'll have to use calculus and differentiating to solve this.

Differentiate the given equation with respect to x:

x^2 + y^2 = 169

2x + 2y * (dy/dx) = 0

Solve for dy/dx:

dy/dx = -x/y

Now, what this derivative means is actually the slope of the tangent line at the point (x, y).

Substituting 5 in for x and 12 in for y, we get:

dy/dx = -5/12

So, the slope is -5/12

Now, we have a slope (m = -5/12) and a point (5,12), so we can write an equation in point-slope form, which is: [tex]y-y_1=m(x-x_1)[/tex], where (x_1, y_1) is the point and m is the slope. So, we have:

y - 12 = [tex]\frac{-5}{12}[/tex] (x - 12)

We can then solve for y (if you want): y = [tex]\frac{-5}{12}[/tex] x +17.

Answer: 2/5

Step-by-step explanation: The total number of letters available to choose from is 10. You want to know the probability of 4 of those 10. So you divide 4/10. When you simplify that fraction it becomes 2/5.

The solution is 2/5

The probability of choosing a letter from Q to T is given by the equation

A = 2/5

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of choosing a letter from Q to T be represented as A

Now , the equation will be

Let the letters be represented as set 1 = { Q , R , S , T , U , V , W , X , Y , Z }

The total number of letters = 10 letters

The number of letters from Q to T = 4 letters

So , the probability of choosing a letter from Q to T is A = number of letters from Q to T / total number of letters

Substituting the values in the equation , we get

Probability of choosing a letter from Q to T is A = 4/10

On simplifying the equation , we get

Probability of choosing a letter from Q to T is A = 2/5

Therefore , the value of A is 2/5

Hence , the probability is 2/5

The equivalent fraction for the decimal 1.240 is 31/25 after simplifying the initial fraction of 1240/1000. None of the provided options, A) 180/3333, B) 18/333, C) 180/333, or D) 180/33, are correct, with the closest incorrect answer being D) 180/33.

The question asks to find the fraction equivalent to the decimal number 1.240. To solve this, we can first write 1.240 as a fraction with a denominator of 1000, since there are three digits after the decimal point. This gives us 1240/1000. We can simplify this fraction by dividing both the numerator and the denominator by the greatest common divisor, which in this case is 10. Thus, the simplified fraction is 124/100. But we can simplify further by reducing the fraction to remove any common factors.

Another common factor here is 4, which when divided into both numerator and denominator, gives us the equivalent fraction of 31/25. This fraction is not listed as any of the provided options, suggesting there might be a typo or mistake in the options given. If we establish the correct fraction 31/25, none of the options A, B, C, or D match. However, Option D, 180/33, is the only option that also results in a number slightly larger than 1, but it still does not match exactly.
