Draw two possible rectangles for 20 units perimeter find the area

1 answer:

6 0

Perimeter = 2 (length + width)
To get a perimeter of a rectangle of 20 units, you need the length + width as 10 units. The combination possibilities would be 1and 9, 2 and 8, 3 and 7, 4 and 6. Use any one set and find the area
Area = length * width
area= 1*9 = 9 units^2
area = 2*8 = 16 units^2
area = 3*7 = 21 units^2
area = 4*6 = 24 units^2

1.)Given the recursive definition LaTeX: a_{n+1}=2\cdot a_n+1a n + 1 = 2 ⋅ a n + 1, and that LaTeX: a_1=1a 1 = 1, find LaTeX: a_

aksik [14]

Answer:

1) 1023

2) 8

Step-by-step explanation:

Given:

$a_{n+1}=2\cdot a_n + 1$ and $a_1 = 1$

Then, the next table can be computed (only the first terms are explicitely shown)

n $a_n$

1 1

2 $a_{2}=2\cdot 1 + 1 =$ 3

3 $a_{3}=2\cdot 3 + 1 =$ 7

4 15

5 31

6 63

7 127

8 255

9 511

10 1023

Given

$t_n=n^2-2n$

Then, the next table can be computed

n $t_n$

1 $t_1=1^2-2(1) =$ -1

2 $t_2=2^2-2(2) =$ 0

3 $t_3=3^2-2(3) =$ 3

4 $t_4=4^2-2(4) =$ 8

12 POINTS FIND THE MISSING LENGTH OF THE ANGLE

Aleks04 [339]

Sorry if wrong but here I go
so basically
you need to find the scale factor so
14/10=1.4 and 21/15=1.4

so I take the scale factor 1.4 and divide by 20
20/1.4= about 14.25 or to be exact 14.2857142857
