What are the first three terms of the sequence defined by the following equation?

an = 2 • (-3)n - 1.

Answers

Answer 1

Answer:

-7, -13, -19

Step-by-step explanation:

plug in 1,2, and 3 into the part of the equation "n".

Answer 2

Answer:

a1 = -7

a2 = - 13

a3 = - 19

Step-by-step explanation:

n = 1

a1 = 2*(-3)*1`- 1

a1 = -6 - 1

a1 = - 7

n=2

a2 = 2(-3)*2 - 1

a2 = -12 -1

a2 = - 13

n3 = 2(-3)*3 - 1

n3 = -18 - 1

n3 = -19

Each term is - 6 away from the previous one.

The equation of the line for the given data set of scatter plots will be y =- x. Since their Mean(M) is equal.

What is the Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given a data set of the number of text messages sent (x) and text messages received (y) by 10 students in a half hour.

so

x     y

0    2

5    1

6    4

8    12

11    11

12    13

15    11

17    20

21    22

24    23

Where M of x = 11.9

also the M of y = 11.9

Sum of X = 119

Sum of Y = 119

Mean X = 11.9

Mean Y = 11.9

The sum of squares (SSX) = 504.9

The sum of products (SP) = 504.9

Regression Equation = ŷ = bX + a

b = SP/SSX = 504.9/504.9 = 1

a = MY - bMX = 11.9 - (1*11.9) = 0

ŷ = 1X - 0

Thus the equation of line best fit will be y = x.

Answer:

53.1

Step-by-step explanation:

They're equal, so 8 = 31 and 13.7 = x

8/31 = 13.7/x

31(13.7) / 8 = 53.0875

Round your answer to nearest tenth to get 53.1

The rounded length of DE is 53.1.

What is similar triangles?

Similar triangles are triangles that have the same shape, but their sizes may vary.

What is the measure of DE?

The both the triangles are similar, so the side length CB will be equal to FE and the side length AB will be equal to DE. Hence, the equation formed will be,

[tex]\frac{8}{31}=\frac{13.7}{DE}[/tex]

On solving this equation, we have DE=53.0875.

Therefore, the rounded length of DE is 53.1.

A square and a rectangle have the same perimeter. The rectangle is 13 cm long and 7 cm wide.
Which is the length of a side of the square?

Answers

The length of each side of a square is 10 cm.

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know, the perimeter of a rectangle is 2(length×width) and the perimeter of a square is 4×(side).

Given, The length and width of the rectangle are 13cm and 7 cm respectively.

Therefore, the perimeter of the rectangle is = 2(13×7) = 2×20 = 40 cm.

So, The perimeter of the square is also 40 cm.

Therefore, The length of the side is 4×side = 40.

side = 40/4.

side = 10 cm.
