a) The number of possible area code numbers is: 69,299. b) the number of possible social security numbers is: 68,665,031,401

a. The first three digits can be any number from 001 to 999, except for 666. Since X can be any number from 1 to 7, there are 7 choices for X. For Y and Z, there are 10 choices each (0-9). Therefore, the number of possible area code numbers is:

(7 choices for X) x (10 choices for Y) x (10 choices for Z) - 1 (for 666) = 69,299

b. The middle two digits can be any number from 01 to 99, which gives 99 choices. The last 4 digits can be any number from 0001 to 9999, which gives 9999 - 1 (for 0000) = 9998 choices. Therefore, the number of possible social security numbers is:

(69,299 choices for the area number) x (99 choices for the group number) x (9998 choices for the serial number) - 1 (for 123-45-6789) = 68,665,031,401

The value of (f∘g)(x) is 3x² - 2.

What is a function?

Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Here, we have

Given: f(x) = √x²-4 and g(x) = 3x²

We have to find the value of (f∘g)(x).

(f∘g)(x) = f(g(x))

(f∘g)(x) = f(3x²)

f(3x²) = √9x⁴- 4

f(3x²) = 3x² - 2

Hence, the value of (f∘g)(x) is 3x² - 2.

The average rate of change of the given function between the two given values is: 0.82

The Average Rate of Change of a function is one that is defined as the average rate at which one quantity is changing with respect to another thing changing. Thus, an average rate of change function is basically a process that helps to calculate the amount of change in one item divided by the corresponding amount of change in another.

It is given by the formula:

f'(x) = [f(b) - f(a)]/(b - a)

We are given the function:

f(x) = √(3x - 11)

Thus from x1 = 4 to x2 = 6, we will have:

f(4) = √(3*4 - 11) = 1

f(6) = √(3*6 - 11) = √7

Thus:

f'(x) = ((√7) - 1)/(6 - 4)

f'(x) = 0.82

Given question is not having enough information, the complete question is attached below,

The values of x , y and z in the parallelogram are 12, -20 and -33 respectively

A parallelogram is a quadrilateral with opposite side equal to each other and opposite sides parallel to each other.

The opposite angles of parallelogram are equal . Consecutive angles in a parallelogram are supplementary .

Therefore,

-4y + 5 = 85

-4y = 85 - 5

-4y = 80

divide both sides by -4

y = 80 / -4

y = - 20

Therefore, let's find x and z as follows:

8x - 1 + 85 = 180

8x = 180 - 84

8x = 96

divide both sides by 8

x = 96 / 8

x = 12

Let's find z

- 3z - 4 + 85 = 180

-3z = 180 - 81

-3z = 99

divide both sides by -3

z = 99 / -3

z = -33

The equation that represent the graph is C) y=3x.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here let us take the two points [tex](x_1,y_1)=(1,3) , (x_2,y_2)=(3,9)[/tex].

Now using slope formula then,

=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> m = [tex]\frac{9-3}{3-1}=\frac{6}{2}=3[/tex].

Now using equation formula then,

=> [tex]y-y_1=m(x-x_1)[/tex]

Answer:

lesser x = 9

greater x = 11

Step-by-step explanation:

(x-10)² - 1 = 0

(x-10)² = 1

(x-10) = +- root1 (positive and negative root1)

So (x-10) = +1 and (x-10) = -1

Firstly

X - 10 = 1

X = 11

Secondly

X - 10 = -1

X = 9

So you have x = 9, and x = 11

The smaller one is the lesser x (9)

The larger one is the greater x (11)

Recall that if two tangents meet outside a circle, their length will be the same based on the tangents theorem.

Therefore, note that every line segments that appear tangent and intersect each other outside the circle have the same length.

Thus, we have:

Perimeter of the quadrilateral PQRS = 52.5 + 37.5 + 23 + (37.5 - 23) + 27.1 + (52.5 - 27.1)

The value of quantity after 0.2 hours is, 960

Given that;

A quantity with an initial value of 480 grows exponentially at a rate such that the quantity doubles every 6 minutes.

We know that;

The exponential growth function is

A = A₀ (1 + r)ⁿ

Where, A= The number of quantity after t days

A₀ = initial number of quantity

r = rate of growth

n = time in minutes

A quantity with an initial value of 830 grows at a rate such that the quantity doubles in 0.2 hours = 12 minutes

And, A = 2 x 480 = 960

A₀ = 480

n = 12 minutes

r = ?

⇒ A = A₀ (1 + r)ⁿ

⇒ 960 = 480 (1 + r)¹²

⇒ 2 = (1 + r)¹²

⇒ [tex]r = \sqrt[12]{2} - 1[/tex]

Now, to find the quantity after 12 minutes, we plug A = 830, t = 12 minutes in exponential function;

The chef makes 11 batches of dumpling wrappers.

What is dumpling wrapper?

Dumpling wrappers are thin pieces of dough that are used to wrap around fillings to make dumplings. They are a staple in many Asian cuisines, including Chinese, Japanese, Korean, and Thai. The dough is typically made with flour, water, and salt, and is rolled out into thin circles or squares. The size and thickness of the wrappers can vary depending on the type of dumpling being made and the regional cuisine. Dumpling wrappers can be used to make a variety of dumplings, such as pork and cabbage dumplings, shrimp dumplings, potstickers, and gyoza.

Let's assume that the chef makes "n" batches of dumpling wrappers.

For each batch of dumpling wrappers, the chef uses 2 cups of flour.

So, the total amount of flour used for making "n" batches of dumpling wrappers is 2n cups of flour.

In addition to the 2 cups of flour for each batch, the chef also uses an additional § cup of flour to keep the dough from sticking. So, the total amount of flour used for "n" batches is 2n + § cups of flour.

According to the problem statement, the chef uses a total of 21 cups of flour to make "n" batches of dumpling wrappers. So, we can set up the following equation 2n + § = 21

To solve for "n," we need to first convert the § cup of flour to a decimal. § is equivalent to 0.25 cups of flour.

So, the equation becomes 2n + 0.25 = 21

Subtracting 0.25 from both sides,

2n = 20.75

Dividing both sides by 2,

n = 10.375

Since we can't have a fraction of a batch, we can round up to the nearest whole number. Therefore, the chef makes 11 batches of dumpling wrappers.

The 7th term of the binomial expression given can be found to be 8.136 × 10^7 × x^(-4)

To find the 7th term of (3x - 4/x²)¹⁴, we can use the binomial theorem, which states that for any positive integer n and any real numbers a and b:

(a + b)ⁿ = ∑(C(n, k) x a^(n-k) x b^k)

Using the binomial theorem formula, the 7th term can be calculated as follows:

Term_7 = C(14, 6) x (3x)^(14-6) x (-4/x²)^6

First, let's find C(14, 6):

C(14, 6) = 14! / (6! x (14-6)!)

C(14, 6) = 14! / (6! x 8!)

C(14, 6) = 3003

Answer:

 39 1/3 = 118/3 square units

Step-by-step explanation:

You want the area under the curve y = -x² +9x on the interval [3, 5].

The fundamental theorem of calculus tells us the integral of the function will be its anti-derivative. That is, for f(x) = -x² +9x, we want the function F(x) whose derivative is f(x). The reverse of the power rule for derivatives can be used:

  [tex]F(x)=-\dfrac{x^3}{3}+9\dfrac{x^2}{2}[/tex]

The area of interest is ...

  F(5) -F(3) = -1/3(5³ -3³) +9/2(5² -3²) = -98/3 +72

  F(5) -F(3) = 39 1/3

The area under the curve between x=3 and x=5 is 39 1/3 square units.
