Greetings from Brasil...

To solve this question, just replace X of function F(X) with A + 3

F(X) = 2X² - 4X - 3

F(A + 3) = 2 · (A + 3)² - 4 · (A + 3) - 3

      (A + 3)² = A² + 2 · A · 3 + 3²

F(A + 3) = 2 · (A² + 6A + 9) - (4A + 12) - 3

F(A + 3) = 2A² + 12A + 18 - 4A - 12 - 3

Well, I dont think that amount of money is a real amount so.

But my guess would be $8.60

Explanation:

Since you provided us with 5,9, and 7, you should use the 7 to round up the next number. So, you round the 9, to 10, so you add the 1 from the 10, on the 5. So it is 6. So your answer is $8.60.

Answer:

≈ 33.3 cm²

Step-by-step explanation:

Given the linear ratio of 2 similar cones = a : b , then

ratio of their areas = a² : b²

Here the ratio of radii = 2 : 3 , thus

ratio of areas = 2² : 3² = 4 : 9

let x be the area of the smaller cone then by proportion

[tex]\frac{4}{x}[/tex] = [tex]\frac{9}{75}[/tex] ( cross- multiply )

9x = 300 ( divide both sides by 9 )

x = 33.33333

Thus

surface area of smaller cone ≈ 33.3 cm² ( nearest tenth )

Answer:

310

Step-by-step explanation:

What is 310 as a decimal? To write 310 as a decimal you have to divide numerator by the denominator of the fraction. 310 is not a fraction so it is a decimal already.

Answer:

3.1 is a decimal and 310/100 or 310% is the percentage for 310/100.

Answer:

Probability = [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Length of segment AD = 12 units

Since, AC = CD

Therefore, AC = CD = [tex]\frac{12}{2}[/tex] = 6 units

Since, AB = BC

Therefore, AB = BC = [tex]\frac{1}{2}AC[/tex] = 3 units

Number of total segments = 5

Number of segments having measure greater than three = 3

(AC = CD = 6 units and AD = 12 units)

Probability that the measure of a segment is greater than 3

= [tex]\frac{\text{Number of segments measuring greater than 3}}{\text{Total number of segments}}[/tex]

= [tex]\frac{3}{5}[/tex]

Answer:

I believe the answer would be step 1: 12x + 15 = 12, and step 2: 12x = -3.

Step-by-step explanation:

3(4x + 5) = 12, you would foil and do 3 times 4x which is 12x, then do 3 times 5 which is 15. So the result would be 12x + 15 = 12.  And the step 2 that goes along with this answer. you would do -15 on both sides of the equal sign, so now you have 12x = 12 - 15 which is -3, so it would be 12x = -3

Answer:

Step 1 would be the answer: Step 1: 12x + 15 = 12 Step 2: 12x = −3 Step 1: 12x + 5 = 12

Step-by-step explanation:

The value of P for the expression PV = nRT will be P=nRT/V.

Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given expression is PV = nRT. The value of p for the expression is calculated as:-

PV = nRT

P = nRT / V

Therefore, the value of P for the expression PV = nRT will be P=nRT/V.

Answer:

1. How many points was each part worth?

 - 12 points

2. How many questions did part A have?

 - 2 questions

3. How many questions did Part B have?

 - 3 questions

Step-by-step explanation:

We can set up our equation like this:

6x = 4y

In the above equation, x is representing the number of true/false questions and y is representing the nymber of multiple choice questions.

Now, the problem tells us that they want the least number of points possible so we know we need to use low numbers.

Since 6 is higher than 4, it's easier to go off of there.

6 x 1 = 6                        4 is too big to go into 6 so we will move on.

6 x 2 = 12                      4 goes into 12 3 times so we can use this.

Now that we've figured this out, we can put it in our equation:

6(2) = 4(3)

In the above equation, we can see that I've put 2 in for x because we multiplied 6 by 2 to get 12. I also put 3 in for y because we multiplied 4 by 3.

Now we can start with the questions:

1. How many points was each part worth?

Each part was worth 12 points because we can multiply 6 by 2 and get 12 or 4 by 3 and get the same thing

2. How many questions did part A have?

Part A had 2 questions because this is what x was when we multiplied by 6

3. How many questions did Part B have?

Part B had 3 questions because this is what y was when we multiplied by 4

Hope this helps!!

Answer:

Im not gonna hand it to you, but heres what you need to solve it. :)

Step-by-step explanation:

An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. We can write this in terms of the composition of f and g as g(f(x))=x.

Answer:

14

Step-by-step explanation:

First, we must identify what the question is asking.

84 students are being split into 6 groups.

If you have a calculator, you can simply enter "84 / 6".

If not, we must do some long division!

6 | 84

How many times does "6" go into "8"? 1 time! Now we subtract 6 from 8.

  1      

6| 84                      (Bring down the 4 afterwards)

   -6      

  1      

6| 84                      How many times does 6 go into 24?  4 times!

   -6      

  24

  14    

6| 84                      How many times does 6 go into 24?  4 times!

   -6      

  24

The answer is 14!

Step-by-step explanation:

Since mean is the average number of students, the formula for calculating the mean attendance of students is expressed as;

Mean = total number of student/sample size

[tex]\overline x = \frac{\sum Xi}{N}[/tex]

Given mean = 20

Since the question talks about the first four meetings, the sample size = 4

[tex]20 = \frac{\sum Xi}{4}\\ \\\sum Xi = 20 * 4\\\\\sum Xi = 80[/tex]

Since the sum total of students for the first four meetings is 80, hence the number of students who attended the meeting is greater than 20

The expression to determine number of muffins each friend gets is ; m = [tex]\frac{x}{3}[/tex] - 2.

It is given that 6 muffins are freeze and rest are equally shared among yourself and 2 friends.

We have to find out the number of muffins each one will get.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.

As per the question ;

The number of freeze muffins = 6

The rest of muffins are equally divided between me and 2 other friends.

Let's assume that the total number of muffins is x.

The number of muffins distributed between 2 friends and me is ;

= x - 6

The number of muffins (m) each one will get  ;

m =  [tex]\frac{x-6}{3}[/tex]

or

m = [tex]\frac{x}{3}[/tex] - [tex]\frac{6}{3}[/tex]

or

m = [tex]\frac{x}{3}[/tex] - 2

Thus , the expression to determine number of muffins each friend gets is ; m = [tex]\frac{x}{3}[/tex] - 2.
