The upper and lower bounds for the numbers are illustrations of approximation

The numbers are given as:

a = 6.54 (to 3 significant figures)

b = 123 (to 3 significant figures)

(a) a + b

We have:

a + b = 6.54 + 123

a + b = 129.54

When approximated, the bounds to three significant digits are:

Lower bound = 129

Upper bound = 130.1

(b) ab

We have:

ab = 6.54 * 123

a + b = 804.42

When approximated, the bounds to three significant digits are:

Lower bound = 804

Upper bound = 805

(c) a/b

We have:

a/b = 6.54/123

a/b = 0.0531707317

When approximated, the bounds to three significant digits are:

Lower bound = 0.0531

Upper bound = 0.0532

(d) b - 1/a

We have:

b - 1/a = 123 - 1/6.54

b - 1/a = 122.847094801

When approximated, the bounds to three significant digits are:

Lower bound = 122

Upper bound = 123

Step-by-step explanation:

Scatter plots' primary uses are to observe and show relationships between two numeric variables. ... Relationships between variables can be described in many ways: positive or negative, strong or weak, linear or nonlinear. A scatter plot can also be useful for identifying other patterns in data.

The point of intersection is the point where two or more functions meet.

The graphs of the hyperbola and ellipse have 0 point of intersection

The given parameters are:

[tex]\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}[/tex]

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}[/tex]

To determine the points of intersection, we simply equate both equations.

So, we have:

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }[/tex]

Cancel out the common terms

[tex]\mathbf{y^2 - 3y = - 4y^2 - 8y }[/tex]

Collect like terms

[tex]\mathbf{y^2 +4y^2= 3y - 8y }[/tex]

[tex]\mathbf{5y^2= - 5y }[/tex]

Divide through by 5

[tex]\mathbf{y^2= - y}[/tex]

Divide through by y

[tex]\mathbf{y= -1}[/tex]

The system of equation does not give room to calculate the x-coordinate at the x-axis.

Hence, the graphs of the hyperbola and ellipse have 0 point of intersection

Answer:

X=60°

Step-by-step explanation:

A1=100° vertically opposite angles

100°=2x-20°

120°=2x

X=60°

Answer:

AC is perpendicular to CD, and DB is perpendicular to AB

Answer:

43 degrees

Step-by-step explanation:

The angles are vertical angles. All vertical angles are congruent meaning that these 2 expressions can be set equal to each other. Then, solve for x and finally plug x back in to get the answer.

(4x+19)=(6x+7)

4x+12=6x

12=2x

x=6

Now, we can plug 6 into the expression given to show that both angles are 43 degrees.

The question gives us two points,  (-7,2) and (21,-10), from which we can find the slope and later the equation of the line.

Finding the Slope  

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                        =  (2 - (- 10)) ÷ (-7 - 21)    

                                        =   - ¹²/₂₈

                                        =   - ³/₇

Checking my answer:  

We can use the slope we found and a point to write the equation of a line. If the line passes through both points, then we calculated the slope correctly.  

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y + 10 = - ³/₇ (x - 21)

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.

Answer:

60%

Step-by-step explanation:

The first step is to divide 27 by 45 to get the answer in decimal form:

27 / 45 = 0.6000

Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.6000 * 100 = 60.00%

60

Step-by-step explanation:

If you take 45 percent of a number and get 27, then what is that number? In other words, you know that 45 percent of a number is 27 and you want to know what that initial number is.

To solve this problem you multiply 27 by 100 and then divide the total by 45 as follows: (27 x 100) / 45

When we put that into our calculator, we get the following answer:

60

Therefore, the answer to "27 is 45 percent of what number?" is 60, and you can also derive that 45 percent of 60 equals 27.

Answer:

Linear.

Cubic.

Step-by-step explanation:

Two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.

" Domain is defined as the set of all input values in the given function."

" Range is defined as the set of all output values in the given function."

According to the question,

For linear function we can put all the real numbers for the independent variable 'x' that is ( -∞ , ∞).

Domain of a linear function = ( -∞ , ∞).

Output values of the linear function is set of all real numbers (-∞,∞).

Range of a linear function = (-∞,∞).

For cubic function

Cubic function is an odd polynomial . One end extends to +∞ and other end to -∞.

Domain and range of cubic function (-∞,∞).

Hence, two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.
