Answer:

The number in decimal expression is:

3.1

Step-by-step explanation:

We have to write the given number in a decimal expression.

The information about the number is given as:

three and ten hundredths.

Hence, in decimals the number is written as:

3.1

( since , three is to be written before the decimal point

as 3 is 3.0

and the number 10 is to be written after the decimal .

since, 10/100=0.1)

Hence, the number in decimal expression is:

3.1

The decimal equivalent to three and ten hundredths is 3.1

1 hundredth = 1/100 = 0.01

10 hundredth = 10/100 = 0.1

Therefore,

three and ten hundredths

= 3 + 0.1

= 3.1

Answer:

The amount before the tip  is $50.

Step-by-step explanation:

Given : Matt paid $55 at a restaurant. That amount included a 10% tip.

To find : What was the check amount before the tip?

Solution : We have given

Matt paid  = $55 .

amount included a 10% tip.

Let the amount before the tip = x.

Tip amount = 10% of x is

[tex]\frac{10 x}{100}[/tex] = 0.1 x .

Tip amount = 0. 1 x

Total amount = x + 0.1x = 55 .

1.1 x = 55.

On dividing both sides by 1.1

x = 50.

So, the amount before the tip  is $50.

Therefore, The amount before the tip  is $50.

The distance between the point P( 8 , 0 , -6 ) to the plane x + y + z = 6 is

d = ( 4 / √3 )

What is the distance between a point and a plane?

The distance between a point and a plane is the smallest perpendicular distance between the point and the plane in question. In other words, the length of the perpendicular parallel to the normal vector dropped from the given location to the provided plane is the shortest distance between two points.

Let the point be P( x₀ , y₀ , z₀ )

Let the plane be Ax + By + Cz + D = 0

The distance between point P and plane is

d = | Ax₀ + By₀ + Cz₀ + D | / √ ( A² + B² + C² )

Given data ,

Let the point be P( x₀ , y₀ , z₀ ) = P ( 8 , 0 , -6 )

Let the equation of plane be x + y + z = 6

A = 1

B = 1

C = 1

D = -6

Now , the distance between the point and the plane is given by ,

d = | Ax₀ + By₀ + Cz₀ + D | / √ ( A² + B² + C² )

Substituting the values in the equation , we get

d = | 8 + 0 + ( -6 ) + ( -6 ) | / √ ( 1 + 1 + 1 )

d = | 8 - 6 - 6 | / √3

d = | -4 | / √3

d = 4 / √3

Therefore , the value of d = 4 / √3

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Let's start by subtracting the initiation fee from the total amount Cleo paid:

$174.99 - $24.99 = $150

This represents the total amount Cleo will pay for the monthly membership fees.

To find out the number of months of membership this represents, we divide by the monthly fee:

$150 ÷ $12.50 = 12

The total area of the figure, which includes a rectangle and a semicircle, is 29.00ft². This is achieved by calculating the individual areas of the rectangle and semicircle, and then adding them together.

The figure in question is composed of a rectangle and a semicircle. The area of a rectangle is found by multiplying its length by its width, so the area of the rectangle part is 7.2ft * 3.4ft = 24.48ft². The area of a semicircle is found using the formula ½πr², where r is the radius of the circle. In this case, the diameter of the semicircle is the same as the width of the rectangle (3.4ft), so the radius will be half of that (1.7ft). Therefore, the area of the semicircle is ½π(1.7ft)² = 4.52ft² (rounded to the nearest hundredth). So, the total area of the figure is the sum of the rectangle and the semicircle area, which equals to 24.48ft² + 4.52ft² = 29.00ft².

The area of the figure which is composed of a semi-circle and a rectangle is approximately 23.24 ft².

The figure in the image is composed of a semi-circle and a rectangle.

The area of a semicircle is expressed as;

A = 1/2 × πr²

The area of a rectangle is expressed as;

Area = length × width

From the diagram;

Diameter = 3.4 ft

Radius r = 1.7 ft

Width of the rectangle = 3.4ft

Length = 7.2ft - 1.7ft = 5.5ft

Now, to determine the area of the figure, we sum the area of the semi-circle and the area of the rectangle.

Area =  ( 1/2 × πr² ) + ( length × width )

Plug in the values:

Area =  ( 1/2 × 3.14 × 1.7² ) + ( 5.5 × 3.4 )

Area =  ( 1/2 × 3.14 × 2.89 ) + ( 5.5 × 3.4 )

Area =  4.5373 + 18.7

Area = 23.24 ft²

Therefore,  the total area has a measure of 23.24 ft².

Answer:

1. x² + 2x + 2

2. x² + 4

3. x² - 4x + 8

Step-by-step explanation:

(1) ( x+1+i ) ( x+1-i )

= ( x+1 )²- i²  [ Since ( a+b ) ( a-b ) = a² - b² ]

= x² + 1 + 2x - ( √-1 )²

= x² + 1 + 2x + 1

= x² + 2x + 2

(2) ( x+2i ) ( x - 2i )

= x² - (2i)² [ ( a+b ) ( a-b ) = a² b²

= x² - 4i²

= x² - 4 (-1) [Since i² = -1 ]

= x² + 4

(3) ( x - 2i - 2 ) (x + 2i - 2 )

= ( x-2 )² - ( 2i )² [ ( a+b ) ( a-b ) = a² - b² ]

= x² + 4 - 4x - 4 ( i )²

= x² + 4 - 4x - 4 ( -1 )²

= x² - 4x + 4 + 4

= x² - 4x + 8

The algebraic expression that is equivalent to the given rational expression is (x-11), but when we substitute x=11 into the expression, we receive 0. However, this leads to an indeterminate form in the original rational expression.

The rational expression given in the question is x^2-121/x+11. If we factorize x^2-121, we'll get (x-11)(x+11), because x^2-121 is a difference of squares. Now, the expression becomes: (x-11)(x+11)/(x+11). We see that (x+11) on numerator and denominator will cancel out each other. This leaves us with (x-11).

Now, let's substitute x=11 in (x-11). We obtain 11-11 which equals 0. So the correct answer is (x-11), but we get 0 when we substitute x=11 into the expression. This actually results in an indeterminate form because the original rational expression becomes a 0/0 form, which points to a situation of undefined or indeterminate form.

In addition to linear, quadratic, rational, and radical functions, there are exponential functions. Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent.

An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours. This can be written as f(x) = 2x.

Before you start,   f(0) = 20 = 1

After 1 hour           f(1) = 21 = 2

In 2 hours              f(2) = 22 = 4

In 3 hours              f(3) = 23 = 8

and so on.

With the definition f(x) = bx and the restrictions that b > 0 and that b ≠ 1, the domain of an exponential function is the set of all real numbers. The range is the set of all positive real numbers. The following graph shows f(x) = 2x.
