Woah that's a lot of words! First recall that the distance between two coordinate points is:

d = square root of (x2 - x1)^2 + (y2-y1)^2

Now Let's break the journey down into parts.

1) SWING SET TO JUNGLE GYM
(-4,2) to (5,2)

d =  \sqrt{ {(5 -  - 4)}^{2} +  {(2 -2 )}^{2}  }

2) GYM TO TIRE SWING
(5,2) to (5,-4)

d =  \sqrt{ {(5  - 5)}^{2} +  {( - 4 - 2 )}^{2}  }
3) TIRE SWING TO SLIDE
(5,-4) to (-4,-4)

Now you try the last two!
You can comment the answer and I can check it.

The total distance will be the sum of all the line sections, so we'll need to add up all the d's. And since 1 unit = 1 yard there's no unit conversion. :)

Answer:

<em>x = 1 + ( √ 10 )/ 2, or x = 1 - ( √ 10 )/ 2; Option A</em>

Step-by-step explanation:

See steps below;

I would prefer answering this question by completing the square, rather than applying a quadratic formula;

3x^2 - 6x - 12 = 0, ⇒ Add 12 to either side,

3x^2 - 6x = 12, ⇒ Divide either side by 3,

x^2 - 2x = 4, ⇒ Write the equation in the form x^2 + 2ax + a^2 = (x + a)^2,

x^2 - 2ax + a^2 = 4 + a^2, ⇒ Solve for a

2ax = -2x,

a = - 1, ⇒ Substitute value of a,

x^2 - 2x + 1 = 4 + 1,

( x - 1 )^2 = 5, ⇒ Solve for x,

x = √5 + 1, and x = - √5 + 1,

In other words; <em>Solution : x = 1 + ( √ 10 )/ 2, or x = 1 - ( √ 10 )/ 2; Option A</em>

Elis [28]

Answer:

working hypothesis.

Step-by-step explanation:

Hypothesis is a technique in mathematics used to identify between two events. The event is tested for hypothesis using the null hypothesis and an alternative hypothesis is set to compare the results. If there are more than one hypothesis then there is working hypothesis technique used to identify the conclusion.

When two number cubes are rolled, what is the probability of getting 5 or 4 as the product of the two numbers
laiz [17]

Answer:

5/36

Step-by-step explanation:

number cubes are rolled = dies that have 6 faces with numbers 1,2,3,4,5,6

Getting 5 or 4 as the product of the two numbers.

How many ways we can get 5 or 4 as a product?

5 ways : 1*4, 1*5, 2*2, 4*1, and 5*1

All possible  outcomes are 36 (see table)

P = ways to get 4 or 5 as a product/ all possible ways = 5/36
