Q1.

value.

The words to be interchanged are underlined. The function as per definition has exactly one output for each input.

Q2.

Part A

Part B

Answer:

below

Step-by-step explanation:

Question 1:

In a function, every output value corresponds to exactly one input value.

The words that should be switched around are "output" and "input". This is because every input should have have only ONE output.

Question 2:

The following graph fails the vertical line test and is not a function. (YES)

Using the vertical line test to test whether the vertical line passes through the graphed function more then once. If it does, its not a function. If it doesn't, it is a function. Sadly, the vertical lines pass the point on two separate occasions which makes it not a function.

The vertical line shows gives the points (4, 2) and (4, -2).

Best of Luck!

Answer:

see explanation

Step-by-step explanation:

using the identity

tan²x = sec²x - 1

consider the left side

(tanx + secx)² ← expand using FOIL

= tan²x + 2tanxsecx + sec²x

= sec²x - 1 + 2tanxsecx + sec²x ← collect like terms

= 2sec²x + 2tanxsecx - 1

= right side , thus proven

Amount of Niobium-91 initially

= 300/91 =3.2967mol

2040 years = 3 ×680 = 3 half-lives

therefore, amount left = 0.4121mol

mass of Niobium-91 remaining = 0.4121 ×91 =37.5g

Answer:

18-12

Step-by-step explanation:

difference means subtraction so it would be a subtraction problem and you just plug in the numbers and your set.

We will see that the value of a is 12.

We have a Fibonacci sequence, and the first four terms are:

a, 2a, 3a, 5a.

Because it is a Fibonacci sequence, the next term should be the sum of the two previous ones.

3a + 5a = 8a

Then the sum of the first 5 terms is:

(a + 2a + 3a + 5a + 8a) = 228

We can solve this for a.

(1 + 2 + 3 + 5 + 8)*a = 228

19*a = 228

a = 228/19 = 12

So we conclude that the value of a is 12.

Answer: Hi

Step-by-step explanation:

The percentage of the boys at the book fair is 6%

Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.

At a book fair, the ratio of adults to children are:

7 : 3

The total number of people at the book fair = 7 + 3 = 10

The percentage of adults are:

[tex]\mathbf{=\dfrac{7}{10}\times 100\%}[/tex]

= 70% are adults

The percentage of children are:

 [tex]\mathbf{=\dfrac{3}{10}\times 100\%}[/tex]

= 30% are children

However, if from the children, 4 are girls and 1 is a boy.

The total number of children at the fair  = 4 + 1 = 5

The percentage of girls are:

[tex]\mathbf{=\dfrac{4}{5} \times 30\%}[/tex]

= 24%

The percentage of boys at the book fair is:

[tex]\mathbf{=\dfrac{1}{5} \times 30\%}[/tex]

= 6%

Answer:

g(x) = x² + 2

Step-by-step explanation:

If we want to shift a function down, we subtract the number we are asked to move outside the function's argument:

⇒ To shift f(x) b units down → f(x) - b

Similarly, in function notation, if we want to shift a function up, we add the number we are asked to move outside the function's argument:

⇒ To shift f(x) b units up → f(x) + b

Given function f(x) = x²

Shift 2 units up ⇒ x² + 2

Therefore, g(x) = x² + 2

Answer:

160 square units

Step-by-step explanation:

First, lets focus on the triangles.

To find the area of a right triangle, we need to multiply the length by the width, and divide by 2.

(5 * 8) / 2 = 20

(And since there is two triangles, the area of the two is 40.)

To find the area of a rectangle, we need to multiply the length by the width.

15 * 8 = 120

Now we add all the areas together.

120 + 20 + 20 = 160

Is the answer is 160 square units.

Answer:

You would do this problem like a normal varible problem. x=10

Step-by-step explanation:

Since 9x is a right angle the inside would also be 9x

9x+4x+10+40=180

180 because that is how much a triangle equals

combine like terms

13x+50=180

subtract 50 from both sides

13x=130

divide by 13

x=10

Hey there!

First of all, the quotient of a number and 6 means you divide that number by 6.

Let the number be x.

Then, eight more means you add 8:

8+(6÷x)=3

That's the answer.
