We can use the base formula: $a_n=a_1+(n-1)d$

$a_n$ = nth term

$a_1$ = first term

$n$ = position of the term

$d$ = common difference

First, lets find the common difference of the sequence.

12 - 5 = 7

19 - 12 = 7

26 - 19 = 7

Second, find the variables we already know.

$a_1$ = 5

$d$ = 7

Put these values into the formula: $a_n = 5+(n-1)7$

We can use this expression to solve for the fifth term.

$a_5=5+(5-1)7\\a_5=5+(4)(7)\\a_5=5+28\\a_5=33$

Therefore, the answer is $a_n = 5+(n-1)7$

Best of Luck!

N7+5 because you start off with 5 and gradually increase by 7. n is the number in the sequence you will try to find

The following set of coordinates represents which figure? (7, 10), (4, 7), (6, 5), (9, 8) Parallelogram Rectangle Rhombus Square

VLD [36.1K]

Answer:

The figure is a rectangle

Step-by-step explanation:

* Lets explain how to solve the problem

- To prove the following set of coordinates represents which figure

lets find the distance between each two points and the slopes of

the lines joining these points

- The rule of the distance between two point is

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

- The rule of the slope is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

- <em>Remember:</em>

* Parallel lines have same slopes

* The product of the slopes of the perpendicular lines is -1

# points (7 , 10) and (4 , 7)

∵ $d1=\sqrt{(4-7)^{2}+(7-10)^{2}}=\sqrt{18}$

∵ $m1=\frac{7-10}{4-7}=\frac{-3}{-3}=1$

# points (4 , 7) and (6 , 5)

∵ $d2=\sqrt{(6-4)^{2}+(5-7)^{2}}=\sqrt{8}$

∵ $m2=\frac{5-7}{6-4}=\frac{-2}{2}=-1$

# points (6 , 5) and (9 , 8)

∵ $d3=\sqrt{(9-6)^{2}+(8-5)^{2}}=\sqrt{18}$

∵ $m3=\frac{8-5}{9-6}=\frac{3}{3}=1$

# points (9 , 8) and (7 , 10)

∵ $d4=\sqrt{(7-9)^{2}+(10-8)^{2}}=\sqrt{8}$

∵ $m4=\frac{10-8}{7-9}=\frac{2}{-2}=-1$

∵ d1 = d3 = √18 and d2 = d4 = √8

∴ Each two opposite sides are equal

∵ m1 = m3 = 1 and m2 = m4 = -1

∴ Each two opposite sides are parallel

∵ m1 × m2 = 1 × -1 = -1

∵ m2 × m3 = 1 × -1 = -1

∵ m3 × m4 = 1 × -1 = -1

∵ m4 × m1 = 1 × -1 = -1

∴ Each two adjacent sides are perpendicular

- The set of coordinates represents a figure has these properties:

1. Each two opposite sides are equal

2. Each two opposite sides are parallel

3. Each two adjacent sides are perpendicular

∴ The figure is a rectangle

Which of the following rational function is graphed below?

steposvetlana [31]

9514 1404 393

Answer:

B. 1/((x -1)(x -2))

Step-by-step explanation:

The vertical asymptotes at x=1 and x=2 tell you the denominator will have factors such that these values make it zero: (x -1)(x -2). That is sufficient to identify choice B as the correct answer.

$f(x)=\dfrac{1}{(x-1)(x-2)}$
