Mathematics
1 answer:
Alenkinab [10]3 years ago
5 0

Answer:

The sequence is arithmetic

we know that

In an arithmetic sequence, the difference between consecutive terms is always the same and is called common difference

In this problem we have

3,9,15,21,...

Let

a1=3, a2=9,a3=15,a4=21

a4-a3=21-15=6

a3-a2=15-9=6

a2-a1=9-3=6

The sequence is arithmetic

The common difference is equal to

(15x2 – 24x + 9) ÷ (3x – 3)
dsp73
\bf 15x^2-24x+9\div 3x-3\implies \cfrac{15x^2-24x+9}{3x-3}\implies \cfrac{\underline{3}(5x^2-8x+3)}{\underline{3}(x-1)}
\\\\\\
\cfrac{5x^2-8x+3}{x-1}\implies \cfrac{(5x-3)\underline{(x-1)}}{\underline{(x-1)}}\implies 5x-3

Draw a square with one vertex on the origin (-3, 5) and a perimeter of 20.
vampirchik [111]

Answer:

Coordinates:

(-3, 5)

(2, 5)

(-3, 10)

(2, 10)

Step-by-step explanation:

Perimeter formula:

length + width + length + width

Insert known value(s):

l + w + l + w = 20

Squares must have the same value for all 4 sides, so what number × 4 will equal 20? 5.

5 + 5 + 5 + 5 = 20

This means coordinates will be 5 units apart:

(-3 + 5, 5) = (2, 5)

(-3, 5 + 5) = (-3, 10)

Mark these coordinates on your grid as you go to double check the shape turns becomes a square:

(2, 5 + 5) = (2, 10)

Counting between them should equal 5 units for each side: I checked using the desmos graphing calculator online.
