Answer:

Step-by-step explanation:

First of all, distance cannot be negative so you eliminate answers A and D immediately.

Now to find the distance between a negative number and a positive number, you either have to take the absolute value of the negative number (to turn it positive) and add it to the positive or take the absolute value of the positive number subtracted by the negative number.

Basically, you're doing this because it compensates for the distance between the negative number and 0.

The only answer choice that is consistent with these terms is B.

A rectangular exercise mat has a perimeter of 36 feet . The length mat is twice the width. Write and solve an equation to determ

Goshia [24]

ANSWER

72 square feet

EXPLANATION

The perimeter of a rectangle is given by:

P= 2l+2w

It was given that, the perimeter of the rectangular mat, is 36 feet.

36= 2l+2w

Divide through by 2.

$18 = l + w...(1)$

It was given also that, the length of the mat is twice its width.

This implies that,

$l = 2w ...(2)$

Put equation (2) into equation (1) to get,

$18 = 2w + w$

$18 = 3w$

$w = 6 \: ft$

This means that the length is 12 ft.

The area of the rectangular mat is

$A = l \times w$

$A = 6 \times 12 = 72 {ft}^{2}$

Determine the first four terms of the sequence in which the nth term is...

Anon25 [30]

Answer:

1/5, 1/6, 1/7, 1/8

Step-by-step explanation:

The formula for the sequence is (n+3)!/ (n+4)!

The first terms uses n=1

a1 = (1+3)!/ (1+4)! = 4!/5! = (4*3*2*1)/(5*4*3*2*1) = 1/5

The first terms uses n=2

a2 = (2+3)!/ (2+4)! = 5!/6! = (5*4*3*2*1)/(6*5*4*3*2*1) = 1/6

The first terms uses n=3

a3 = (3+3)!/ (3+4)! = 6!/7! = (6*5*4*3*2*1)/(7*6*5*4*3*2*1) = 1/7

The first terms uses n=4

a4 = (4+3)!/ (4+4)! = 7!/8! = (7*6*5*4*3*2*1)/(8*7*6*5*4*3*2*1) = 1/8

Find two numbers a and b such that a+b=0 and ab=36

PolarNik [594]

Answer:

b = 6i then a = -6i

b = -6i then a = 6i

Step-by-step explanation:

a+b=0

ab=36

a = -b

a(b) = 36

-b * b = 36

- b^2 = 36

b^2 = -36

Take the square root of each side

sqrt(b^2) = sqrt(-36)

b =± 6i

a = - (± 6i)

so b = 6i then a = -6i

b = -6i then a = 6i

valina [46]

Answer:

Gaming Functions

Step-by-step explanation:

I think your teacher is implying for you to explain the function and the "works" behind the game. Maybe talk about the game's programming or the way it's overall structured?
