Step-by-step explanation:

Final answer:

The nth term for the given sequence 1, 7, 15, 25, 37 is derived to be n² + n - 1, which fits the pattern of the sequence accurately.

Explanation:

The sequence given is 1, 7, 15, 25, 37. To find the nth term of this sequence, let's first identify the pattern of differences between the terms. Observing the differences, we see they are 6, 8, 10, and 12, which suggests an arithmetic sequence in the differences. This indicates the original sequence is quadratic.

Using the general formula for the nth term of a quadratic sequence, An² + Bn + C, we can substitute the first few terms to solve for A, B, and C. However, there's a quicker method given the pattern of differences seen in the second layer (6, 8, 10, 12, ...) that increases by 2 each time, suggesting that 2n is involved.

Through analysis, the nth-term formula can be derived as n² + n - 1.

Here's why:

considering n=1 for the first term, we get 1+1-1=1;

for n=2, the formula yields 2^2+2-1=7; and so forth, matching the given sequence precisely.

Explanation on finding distance from a point to the origin as a function of x and showing invariance under rotations.

Distance from point P to the origin as a function of x:

Given point P(x, y) on y = x² – 9.

The distance d from P to the origin is d = √(x² + y²).

Substitute y = x² - 9 into the distance formula to express d as a function of x: d = √(x² + (x² - 9)²).

Invariance of distance under rotations:

The distance from P to the origin remains constant regardless of the rotation, as it depends only on the coordinates of the point and not the orientation of the coordinate system.

Answer:

Option C is correct.

Step-by-step explanation:

The formula is = [tex](1+\frac{r}{n})^{n}-1[/tex]

r = rate of interest

n = number of times its compounded

1. 4.0784% compounded monthly

here n = 12

[tex](1+\frac{0.040784}{12})^{12} -1[/tex] = 1.0403-1 = 0.0403

2. 4.0798% compounded semiannually

here n = 2

[tex](1+\frac{0.040798}{12})^{2} -1[/tex] = 1.0066-1 = 0.0066

3. 4.0730% compounded daily

here n = 365

[tex](1+\frac{0.040730}{12})^{365}[/tex] = 3.328-1 = 2.328

Let

using a graphing tool  

see the attached figure to better understand the problem

we know that

Parallelogram is a quadrilateral with opposite sides parallel and equal in length

so

[tex]AB=CD \\AD=BC[/tex]

The area of a parallelogram is equal to

[tex]A=B*h[/tex]  

where  

B is the base

h is the height  

the base B is equal to the distance AB

the height h is equal to the distance AE  

Step 1

Find the distance AB

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

[tex]A(-4,9)\\B(11,9)[/tex]  

substitute the values

[tex]d=\sqrt{(9-9)^{2}+(11+4)^{2}}[/tex]

[tex]d=\sqrt{(0)^{2}+(15)^{2}}[/tex]

[tex]dAB=15\ units[/tex]

Step 2

Find the distance AE

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

[tex]A(-4,9)\\E(-4.-1)[/tex]  

substitute the values

[tex]d=\sqrt{(-1-9)^{2}+(-4+4)^{2}}[/tex]

[tex]d=\sqrt{(-10)^{2}+(0)^{2}}[/tex]

[tex]dAE=10\ units[/tex]

Step 3

Find the area of the parallelogram

The area of a parallelogram is equal to

[tex]A=B*h[/tex]

[tex]A=AB*AE[/tex]

substitute the values

[tex]A=15*10=150\ units^{2}[/tex]

therefore

the answer is

the area of the parallelogram is [tex]150\ units^{2}[/tex]

The area of the parallelogram is 0 units.

To find the area of a parallelogram, we can use the formula A = base * height. We can find the length of the base by finding the distance between points A and D, which is 11 units. To find the height, we can find the distance between points A and B, which is 0 units. Therefore, the area of the parallelogram is 0 units.

Answer and explanation:

Use the distributive property in two different ways to find the product of 127 and 32.

Distributive property says that,

[tex]a(b+c)=ab+ac[/tex]

We have to find product of 127 and 32,

1) Split 127 as 100+27

[tex]127\times32=(100+27)\times 32[/tex]

Apply distributive property,

[tex]127\times32=100\times 32+27\times 32[/tex]

[tex]127\times32=3200+864[/tex]

[tex]127\times32=4064[/tex]

2) Split 32 as 30+2

[tex]127\times32=127\times (30+2)[/tex]

Apply distributive property,

[tex]127\times32=127\times 30+127\times 2[/tex]

[tex]127\times32=3810+254[/tex]

[tex]127\times32=4064[/tex]

The Java Rectangle class implements both the Shape and Serializable interfaces. Therefore, Rectangle r can be legally assigned to Rectangle, Shape, Serializable, and Object data types. It can't be assigned to a String, Measurable, and ActionListener as Rectangle doesn't implement these.

In Java, the Rectangle class implements the Shape and Serializable interfaces. Therefore, the legal assignments would be:

The rest assignments are not legal because the Rectangle class doesn't implement Measurable, ActionListener interfaces and it cannot be assigned to a String.

at Start of Round 3 David Has: - 1500

During Round 3:

5 Questions: 1000 each correctly

so 5 x 1000 = 5000

3 Questions: - 500 each incorrectly

so 3 x -500 = -1500

at the End of Round 3:

Starting: -1500

During Round 3: 5000 - 1500 = 3500

the end of round 3: -1500 + 3500 = 2000

To prove that [tex]f(x) = x^3 - 1000x^2 + x - 1[/tex] is [tex]\omega(x^3)[/tex] and [tex]o(x^3)[/tex], we must show how the function grows in comparison to x^3 asymptotically.

To prove that [tex]f(x) = x^3 - 1000x^2 + x - 1[/tex] is [tex]\omega(x^3)[/tex] and [tex]o(x^3)[/tex], we need to show two things:

1. Proving that [tex]f(x) = x^3 - 1000x^2 + x - 1[/tex] is [tex]\omega(x^3)[/tex]

For a function to be [tex]\omega(x^3)[/tex], it needs to grow faster than [tex]x^3[/tex] asymptotically. This requires that the ratio of the function to [tex]x^3[/tex] tends towards infinity as x approaches infinity.

Consider:

[tex]\lim_{x \to \infty}[\frac{f(x)}{x^3} ] = \lim_{x \to \infty}[ \frac{x^3-1000x^2+x-1}{x^3} ][/tex]

Simplify the expression:

[tex]\lim_{x \to \infty}[ 1-\frac{1000}{x}+\frac{1}{x^2}-\frac{1}{x^3} ] =1[/tex]

Since the limit does not tend to infinity but instead tends to 1, f(x) is not ω(x^3). We made a mistake in our earlier assumption; let's correct this in the next point.

2. Proving that [tex]f(x) = x^3 - 1000x^2 + x - 1[/tex] is [tex]o(x^3)[/tex]

To show that f(x) is [tex]o(x^3)[/tex], the ratio of f(x) to [tex]x^3[/tex] should tend to zero as x tends to infinity.

Consider:

[tex]\lim_{x \to \infty} [\frac{f(x)}{x^3}] = \lim_{x \to \infty}[\frac{x^3-1000x^2+x-1}{x^3}][/tex]

Simplify the expression:

[tex]\lim_{x \to \infty}[ 1-\frac{1000}{x}+\frac{1}{x^2}-\frac{1}{x^3} ] =1[/tex]

This indicates that the limit tends to 1 and not 0, hence f(x) is not [tex]o(x^3)[/tex] either. We can see in both cases that the limits did not meet the required criteria for [tex]\omega(x^3)[/tex] or [tex]o(x^3)[/tex], implying a misunderstanding in the problem setup.

Answer:

(C) is one more than the power

Step-by-step explanation:

Let us consider a binomial expansion:

[tex](x+y)^2=x^2+2xy+y^2[/tex]

The power of the above expansion is [tex]2[/tex] and the number of the terms in the above binomial expansion are [tex]3[/tex], thus the total number of terms in the binomial expansion is one more than the power.

Hence, Option C is correct.

65*8 = 520 miles traveled

520/80 = 6.5 hours for the car

Answer:

The automobile would take 6.5 hours to complete the trip.

Step-by-step explanation:

This is a case of a inverse variation relationship because when you increase the speed of traveling the time of arriving will reduce, now we have to define the equation and the variables:

Inverse variation equation: [tex]x1y1=x2y2[/tex]

[tex]x1[/tex]: speed of the bus, 65 miles per hour

[tex]y1[/tex]: time to Austin by bus, 8 hours

[tex]x2[/tex]: speed of the automobile, 80 miles per hour

[tex]y2[/tex]: time to Austin by automobile, unknown

Now we can replace the values in the equation and clear [tex]y2[/tex], this is:

[tex]65*8=80*y2\\y2=\frac{65*8}{80} =\frac{520}{80} =6.5\\[/tex]

The automobile would take 6.5 hours to complete the trip.

The annual value of the employer's contribution towards Trina's health insurance plan is $5,580.

Here, we have to find the annual value of the employer's contribution, we need to determine how much the employer pays towards the health insurance plan in one month.

Trina's employer purchased a health insurance plan that costs $550 per month, and Trina pays $85 toward the plan each month.

Therefore, the employer's contribution is the difference between the total cost of the plan and what Trina pays:

Employer's contribution = Total cost of the plan - Trina's contribution

Employer's contribution = $550 - $85

Employer's contribution = $465 per month

Now, to find the annual value of the employer's contribution, we multiply the monthly contribution by 12 (since there are 12 months in a year):

Annual employer's contribution = $465 * 12

Annual employer's contribution = $5,580

So, the annual value of the employer's contribution towards Trina's health insurance plan is $5,580.
