Answer:

\(a_{n}\) = 3n + 4

Step-by-step explanation:

there is a common difference between consecutive terms , that is

10 - 7 = 13 - 10 = 16 - 13 = 3

this indicates the sequence is arithmetic with nth term

\(a_{n}\) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 7 and d = 3 , then

\(a_{n}\) = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Answer:

The nth term = 3n + 4.

Step-by-step explanation:

The formula for the nth term of an arithmetic progression is a(n) = dn + a(1) - d.

So this breaks down simply to,

a(n) = dn + a(1) - d a(n) = 3n + 7 - 3 a(n) = 3n + 4

Answer:

Step-by-step explanation:

The first thing you have to do is find the price of each washing machine after they have been marked down.

The first washing machine is marked down by 40%. Because the price is going down by 40%, the new price will be 60% of the original $390. This is because 100 - 40 = 60. Get rid of 40% of something, and 60% is left.

Knowing this, we can mutiply $390 by 60%, which can also be written as the decimal 0.60.

390 times 0.60 = 234

Ok, so we have the price of the first washing machine. Now, lets look at the second.

Well, this is pretty simple. We do the same thing that we did with the first.

It's initially marked down by 10%, so we start with that. Since the entire price will be 10% less, and 100 - 10 = 90, we can mutiply $390 by 90%, which can be written as 0.90

390 times 0.90 = 351

Now, the new price, $351, is marked down by 30%.

100 - 30 = 70, so we mutiply 351 by 70%, or 0.70.

351 times 0.70 = 245.7

So, now we have the two prices. Washing machine number one is $234, and washing machine number two is $245.70. But why?

Well, it's because of the different ways the two washing machines go on sale. The first one goes on sale all at once, so the ENTIRE price of $390 dollars goes down by 40%.

However, with the second washing machine, the way it goes on sale changes the amount of money that is saved.

Since the second washing machine goes on sale twice, the second sale is a sale on the new price resulting from the first sale.

Since the second sale is 30% off of $351, it is less of a sale than if it was 40% off of $390

This is because, the smaller a number is, the smaller the percentage you are taking away from it is.

For example, if you take away 50% from 1000, you get 500. But, if you take away 40% from 1000 to get 600, and then 10% away afterwards, 10% from 600 is less than 10% from 1000.

Hope that wasn't too confusing, It's not easy to explain using a keyboard.

We are given a matrix A and a scalar λ and asked to show that λ is an eigenvalue of the matrix and determine a basis for its eigenspace.

To determine if λ is an eigenvalue of matrix A, we need to check if there exists a non-zero vector v such that Av = λv. In other words, if multiplying matrix A by vector v results in a scaled version of v. Given the matrix A = [6, 9; -10, 63] and scalar λ = 5, we can find the eigenvectors by solving the equation (A - λI)v = 0, where I is the identity matrix. Substituting the values, we have: [6-5, 9; -10, 63-5]v = 0. Simplifying the equation, we get: [1, 9; -10, 58]v = 0. Solving the system of linear equations, we can find the eigenvectors v corresponding to the eigenvalue λ = 5.

Answer:

The equation of perpendicular bisector of QR is:

y = -\frac{2}{3}x+\frac{22}{3}y=−32x+322

Step-by-step explanation:

Given points are:

Q(-2,0)\ and\ R(6,12)Q(−2,0) and R(6,12)

First of all, we have to find the slope of the given line

So,

m = \frac{y_2-y_1}{x_2-x_1}m=x2−x1y2−y1

Here

(x1,y1) = (-2,0)

(x2,y2) = (6,12)

Let m1 be the slope of QR:

Then

\begin{gathered}m_1 = \frac{12-0}{6+2}\\= \frac{12}{8}\\= \frac{3}{2}\end{gathered}m1=6+212−0=812=23

Let m2 be the slope of perpendicular bisector

We know that the product of slopes of two perpendicular lines is -1

\begin{gathered}m_1.m_2 = -1\\\frac{3}{2}.m_2 = -1\\m_2 = -1 * \frac{2}{3}\\m_2 = -\frac{2}{3}\end{gathered}m1.m2=−123.m2=−1m2=−1∗32m2=−32

The bisector will pass through the mid-point of QR

\begin{gathered}M = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\M = (\frac{-2+6}{2}, \frac{0+12}{2})\\M = (\frac{4}{2}, \frac{12}{2})\\M = (2,6)\end{gathered}M=(2x1+x2,2y1+y2)M=(2−2+6,20+12)M=(24,212)M=(2,6)

Slope-intercept form of equation is:

y = m_2x+by=m2x+b

Putting the value of slope

y = -\frac{2}{3}x+by=−32x+b

Putting (2,6) in the equation

\begin{gathered}6 = -\frac{2}{3}(2)+b\\6 = -\frac{4}{3}+b\\b = 6+\frac{4}{3}\\b = \frac{18+4}{3}\\b = \frac{22}{3}\end{gathered}6=−32(2)+b6=−34+bb=6+34b=318+4b=322

So,

y = -\frac{2}{3}x+\frac{22}{3}y=−32x+322

Hence,

The equation of perpendicular bisector of QR is:

y = -\frac{2}{3}x+\frac{22}{3}y=−32x+322

By working together, they can save time and complete the task faster. Therefore, Leslie and Fran can paint the room in 2.2 hours.

Leslie and Fran working together to paint a room can complete the job in 2.2 hours. This can be calculated by taking the least amount of time it would take for the job to be done (3 hrs) and dividing it by the total amount of time it would take both of them working together (7 hrs). 3 / 7 = 0.428, then multiply 0.428 by 10 to get the tenths place. 0.428 x 10 = 4.28, and round up to 2.2 hrs. Therefore, Leslie and Fran working together could paint a room in 2.2 hrs. This is significantly faster than it would take either of them working alone.

The solution for x in the equation is x = 2b/(2a - c)

The equation is given as

2ax - b = cx + b

Collect the like terms in the above equation

So, we have the following equation

2ax - cx = b + b

Evaluate the like terms in the above equation

So, we have the following equation

2ax - cx = 2b

Factor out x from the equation

x(2a - c) = 2b

Divide both sides by 2a - c

x = 2b/(2a - c)
