The vertex of the function f(x) = x² + 12x is,

⇒ Vertex = (- 6, - 36)

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = x² + 12x

Now, We can change the function into the form,

f (x) = (x - h)² + k

Where, (h, k) is vertex.

Here, The function is,

⇒ f (x) = x² + 12x

⇒ f (x) = x² + 12x + 36 - 36

⇒ f (x) = (x + 6)² - 36

⇒ f (x) = (x - (- 6))² + (- 36)

Hence, By comparing,

Vertex = (h, k) = (- 6, - 36)

Thus, The vertex of the function f(x) = x² + 12x is,

⇒ Vertex = (- 6, - 36)

Answer:

a. 10√2

Step-by-step explanation:

hey, just use Pythagoras theorem

h²=p²+b²=10²+10²=100+100=200

h²=200, h= √200 =√(100×2)=√100×√2=10√2

Answer:

The area is 51 units squared.

Step-by-step explanation:

Since you are finding the area of a triangle, you first start with 12 x 8.5 = 102.

Then, you divide 102 in half, since the shape is a triangle. So, 102 ÷ 2 = 51.

So the answer is 51 units squared.

Lets look at the chart, and see how similar each value is:

At 11, there is:

Both have 1 point. THis is similar

At 12:

Both have 1 point. This is similar

At 13:

One has 1 point, the other has 2 points. This is not similar

Next we have 14:

Both have 2 points. This is similar

15:

Both have 4 points. THis is similar

16:

Both have 3 points. This is similar

17:

One has 2 points the other has 1 point. This is not similar

So,  5 out of the 7 poitns are similar

And remember, the two points that are not similar are only off by 1.

So I would conclude that they are highly similar.

28.8%​ is the probability that a data value is between 48 and 52.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

First, we need to standardize the values and use a standard normal distribution table or calculator.

The standardized value of 48 is:

z = (48 - 48) / 5 = 0

The standardized value of 52 is:

z = (52 - 48) / 5 = 0.8

Now we need to find the probability that a data value is between z = 0 and z = 0.8 in a standard normal distribution. We can use a standard normal distribution table or calculator to find this probability.

Using the table or calculator, we can find that the probability of a data value being between z = 0 and z = 0.8 in a standard normal distribution is approximately 0.2881.

Rounding this answer to the nearest tenth of a percent, we get:

P(48 < x < 52) ≈ 28.8%

Therefore, the answer is D, 28.8%.

Answer:

A) -30 - x = 10 and -30 - x = –10

Step-by-step explanation:

Part 1:

1) Isolate the variable x

-30 - x = 10

-x = 40

2) Multiply both sides by -1

x = -40

Therefore -30 - x = 10 is correct

Part 2:

1) Isolate the variable x

-30 - x = –10

-x = 20

2) Multiply both sides by -1

x = -20

Therefore -30 - x = –10 is also correct

Final Answer: -30 - x = 10 and -30 - x = –10

91%

Step-by-step explanation:

If a soil sample test gives a positive result, it is **91.7%** likely that the soil sample contains organic matter.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Positive results= 95%

Negative results= 5%

Now,

Positive result = 700 * 0.95 = 665

Negative result = 700 * 0.05 = 35

Similarly, for the soil samples that do not contain organic matter, we know that 20% of them will give a positive result and 80% will give a negative result. So, we can multiply 300 by 0.2 and 0.8 to get:

Positive result = 300 * 0.2 = 60

Negative result = 300 * 0.8 = 240

To fill in the missing value in the statement, we can use Bayes' theorem, which states that:

P(A|B) = P(B|A) * P(A) / P(B)

So, we have:

P(contains organic matter | positive result) = P(positive result | contains organic matter) * P(contains organic matter) / P(positive result)

P(positive result) = P(positive result | contains organic matter) * P(contains organic matter) + P(positive result | does not contain organic matter) * P(does not contain organic matter)

P(positive result) = 0.95 * 0.7 + 0.2 * 0.3

P(positive result) = 0.665 + 0.06

P(positive result) = 0.725

Plugging these values into Bayes' theorem, we get:

P(contains organic matter | positive result) = (0.95 * 0.7) / (0.725)

P(contains organic matter | positive result) = (0.665) / (0.725)

P(contains organic matter | positive result) = 0.9172

Therefore, by probability the answer will be 91.7%

Answer:

5. a = 4

7. x = -8

9. x = -1

11. p = 1.1

13. x = -1

15. x = -4

Step-by-step explanation:

2.9a = 11.6

2.9a/2.9 = 11.6/2.9

a = 4

-3.7x = 29.6

-3.7x/-3.7 = 29.6/-3.7

x = -8

(x-5)(-3) = 18

(x-5)(-3)/-3 = 18/-3

x-5 = -6

x-5+5 = -6+5

x = -1

3.6 = -2p+5.8

3.6-5.8 = -2p+5.8-5.8

-2.2 = -2p

-2.2/-2 = -2p/-2

1.1 = p

2x+6 = -4x

2x+6-6 = -4x-6

2x = -4x-6

2x+4x = -4x-6+4x

6x = -6

6x/6 = -6/6

x = -1

21-6x = -11-14x

21-6x-21 = -11-14x-21

-6x = -14x-32

-6x+14x = -14x-32+14x

8x = -32

8x/8 = -32/8

x = -4

Answer:

5.) a= 4

7.) x= -8

9.)x= -1

11.) p= 1.1

13.) x= -1

15.) x= -4

Step-by-step explanation:

5.) divide 11.6 by 2.9a

7.)divide 29.6 by -3.7u

9.) Divide by sides by -3. simplify. Add 5 to both sides. then simplify again x= -1

11.) subtract 5.8 from 3.6 . you're left with -2p=-2.2 divide both sides by -2. you get p=1.1

13.)Subtract 6 from both sides. You get 2x= -4x-6. Add 4x to both sides. then divide -6 by 6 you get x=-1

15.) Simplify both sides of the equation, so add 14x to -6x +21 side, you get 8x= -32 then divide -32 by 8x you get -4
