Answer:

169 (second choice)

Step-by-step explanation:

$13 [6^2 / (5^2-4^2) + 9]$

$13 [6^2 / (25 - 16) + 9]$

$13 [6^2 / 9 + 9]$

13 [36 / 9 + 9]

13 [4 + 9]

13 [13]

What is the answers of 6b and 6c?

Dimas [21]

Hello,

6b) (i) As you can see, in the first year the price drops from 27,000 to 17,000. (Look at year 0-1 on the x axis). To find the percentage drop, find the difference between the two values and divide it over the initial value of 27,000.

So, the percentage drop in the first year is:
(27000-17000) / (27000) = 0.37, or a 37% drop

The answer is 37%.

(ii) For this question, we basically have the same process as the previous question except for the second year.

From year 1 to year 2, the value starts at 17,000 and ends at 15,000.
To find the percentage drop, we do:
(17000 - 15000) / (17000) = 0.118 ≈ 0.12, or a 12% drop

The answer is 12%.

6c) To find the percentage depreciation over the first 5 years, we look at the initial value (x = 0) and the value after 5 years (x = 5), and use these values in the same percentage formula we have been using.

The initial value of the car is 27,000, and after 5 years the value is 8,000.
This is a percentage drop of (27000 - 8000) / (27000) = 0.70, or a 70% drop.

The answer is 70%.

Hope this helps!

A number cube is rolled and a coin is flipped. Let H stand for heads and T for tails. What is the sample space for the experimen

tigry1 [53]

Answer: S={(1,H) , (1,T) , (2,H) , (2,T) , (3,H) , (3,T) , (4,H) , (4,T) , (5,H) , (5,T) , (6,H) , (6,T)}

Step-by-step explanation:

Given: A number cube is rolled and a coin is flipped.

Let H stand for heads and T for tails.

Then the sample space will contain pairs in which the first one shows the number on dice and the second one shows the the outcome for coin after dice is thrown.

Now, the required sample space will be

S={(1,H) , (1,T) , (2,H) , (2,T) , (3,H) , (3,T) , (4,H) , (4,T) , (5,H) , (5,T) , (6,H) , (6,T)}

30 points!!!

AysviL [449]

<h3>Answer: The graph is shown in the attached image below</h3>

-2x means -2*x or "-2 times x" where x is a placeholder for any number you want.

To graph y = -2x, you just need two points. Each point is of the form (x,y)

Let's plug in zero as it is often the easiest to work with.

If x = 0, then -2*x = -2*0 = 0. Notice how I replaced x with 0 and simplified.

Therefore, if x = 0, then y = 0. We have (x,y) = (0,0) as one point on this line. I have marked it as point A in the graph.

Point B is (1, -2) and it is found by plugging x = 1 into the equation to get...

y = -2x

y = -2*1

y = -2

You could find other points, but two points is enough to draw a straight line through them. The slope of this line is -2 = -2/1. The y intercept is 0.
