Answer:

The width is 9.5 ft

Step-by-step explanation:

Perimeter for a rectangle is given by

P = 2 (l+w)

43.8 = 2 (12.4+w)

Divide each side by 2

21.9 = 12.4+w

Subtract 12.4 from each side

21.9-12.4 = w

9.5 = w

The width is 9.5 ft

Answer:

The sequence 3 , 4 , 6 , 10 , 18 described by the 2nd term is t2 = 4 and recursive definition is tn+1 = 2 tn - 2 ⇒ 4th answer

Step-by-step explanation:

* Lets revise the recursive formula

1. Determine if the sequence is arithmetic (Do you add, or subtract, the

same amount from one term to the next?)

2. Find the common difference. (The number you add or subtract.)

3. Create a recursive formula by stating the first term, and then stating

the formula to be the previous term plus the common difference.

a1 = first term;

an+1= an + d

- Where:

# a1 = the first term in the sequence

# an = the nth term in the sequence

# an+1 = the term after the nth term

# n = the term number

# d = the common difference.

* Now lets solve the problem

∵ The recursive definition is tn+1 = 2 tn - 2 and t2 = 4

- Look to the answer we have three answer with second term = 4,

1st , 2nd and 4th

- Lets find the 1st term

∵ t2 = 2 t1 - 2

∵ t2 = 4

∴ 4 = 2 t1 - 2 ⇒ add 2 to the both sides

∴ 6 = 2 t1 ⇒ divide the two sides by 2

∴ t1 = 3

- We have two answer with first term = 3, 2nd and 4th answers

* Lets find the third term

∵ t3 = 2 t2 - 2

∵ t2 = 4

∴ t3 = 2 (4) - 2 = 8 - 2 = 6

∴ The 4th answer has the third term = 6

* The 4th sequence 3 , 4 , 6 , 10 , 18 described by the 2nd term is

t2 = 4 and recursive definition is tn+1 = 2 tn - 2

A tennis ball bounces based on this equation y = x2 - x+2. A dog jumps based on this equation y=2x.

valentina_108 [34]

Answer: when the equations are equal, that is when x = 1 or x = 2

Step-by-step explanation:

The dog will receive the ball , when both equations intercept , that is , when both equations are equal. This implies :

$x^{2}$ - x + 2 = 2x

$x^{2}$ - x - 2x + 2 = 0

x(x-1) - 2 (x - 1 ) = 0

(x - 1 ) ( x - 2 ) =0

Therefore , x = 1 or x = 2

I think your answer should be C. 160,934 Centimeters. :) I rounded it to the nearest thousand, and it is 161,000. I also rounded it to the nearest ten thousand, and it was 160,000. So, C is your answer.

700+a=3944-b=c-80=3000

velikii [3]

Answer:

A = 3244

B = 864

C = 3080

Step-by-step explanation:

700 + a = 3944

-700 -700

a = 3244

3944 - b = c - 80 = 3000

c - 80 = 3000

+80 +80

c = 3080

3944 - b = c ---> 3944 - b = 3080

-3944 -3944

-b = -864 ---> $\frac{-b}{-1} = \frac{-864}{-1}$

How are the two functions f(x) = 0.7(6)x and g(x) = 0.7(6)–x related to each other?

Harlamova29_29 [7]

The answer
f(x) = 0.7(6)x = f(x) = 0.7(6)^x, and g(x) = 0.7(6)–x= g(x) = 0.7(6)^-x=1/0.7(6)^x
so 
g(x) =1/0.7(6)^x=1 /f(x)

 the relationship between f and g are g(x) =1 /f(x) or g(x) . f(x) = 1
