Find the common difference of the arithmetic
sequence 13,9,5,

Answers

Answer: -4

Step-by-step explanation:

13 - 9 = 4

9 - 5 = 4

so, we can see that it is decreasing by 4 each time.

Answer:

common difference is -4

Step-by-step explanation:

The common difference is the amount we add  between terms

13 + d = 9

Subtract 13 from each side

13+d-13 = 9-13

d = -4

Check

9+d = 5

9 + -4 = 5

5= 5

This is true so the common difference is -4

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.

Answers

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

What is the perimeter of a triangle?

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

what is the period of the sinusoidal function

Answers

Answer:

10

Step-by-step explanation:

Period is the distance between two consecutive maximum points, or two consecutive minimum points.

On the given graph the period is the distance between maximum points -7 and 3:

3 - (-7) = 10

Answer:

The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.

From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units

Therefore, 10 units is the right answer.

Solve for h.
h/10 + 5 = 25
so what’s h ??

Answers

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!
