Yes, these -1098.15 and -2,784.75 are rational numbers.

Rational number is the one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively

A rational number is the one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively. Every integer (e.g., 5 = 5/1) and, for instance, the number 3/7 are rational numbers. Boldface Q, also known as blackboard bold, is typically used to signify the set of all rational numbers, also known as "the rationals," the field of rationals, or the field of rational numbers.

Real numbers are those that are sensible. The rational real numbers are those whose decimal expansion either ends after a finite number of digits (for instance, 3/4=0.75) or eventually starts to repeatedly repeat the same finite sequence of digits (9/44=0.204545454). This assertion is accurate not just in base 10, but also in every other integer base, such as the binary and hexadecimal ones

The length of pipe required to produce a pitch of 220 Hz is 2.26 feet.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

The length of a pipe in a panpipe L, in ft, is inversely proportional to its pitch p, in hertz.

The inverse variation is modeled by the equation p = 497/L.

The length of pipe required to produce a pitch of 220 Hz,

= 497/220

= 2.26 feet

Therefore, the length is 2.26 feet.

Clare can go 3 times for her workout cycle

Clare follows the same workout cycle each time she goes to the gym

She spends 1 1/2 hour at the gym

First, she runs 1/3 of an hour

After that, she lifts 1/3 of an hour

The first step is to convert to minutes

60 mins = 1 hour

1/2 × 60

= 30

30 + 60

= 90 mins

convert 1/3 to mins

1/3 × 60

= 20 mins

convert 1/6 to mins

1/6 × 60

= 10 mins

Total mins= 20 + 10

= 30 mins

The number of workout cycles can be calculated as follows

Answer:

  x^8

Step-by-step explanation:

You want to simplify x^10/x^2.

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

Using this rule on the given expression, we find ...

  (x^10)/(x^2) = x^(10-2) = x^8

__

Additional comment

An exponent can be considered to be an indicator of repeated multiplication. That is, it tells how many times the base is a factor in the product. Knowing this, you can use the usual rules of division to cancel common factors:

  [tex]\dfrac{x^{10}}{x^2}=\dfrac{x\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x}{x\cdot x}=x\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x=x^8[/tex]

The size of the shift from function f to function g is 12 units down

The table of values is given as

x 0 1 2 3 4

g(x) -11 -10 -8 -4 4

From the question, we understand that the function g(x) is an exponential function

The parent function of an exponential function in this case, is represented as

f(x) = 2^x

When represented on a table of values, we have

x 0 1 2 3 4

f(x) 1 2 4 8 16

So, we have

x 0 1 2 3 4

f(x) 1 2 4 8 16

g(x) -11 -10 -8 -4 4

Notice that the difference between the values of f(x) and g(x) is 12

This means that

g(x) = f(x) - 12

So, we have

g(x) = 2^x - 12

Hence, the size of the shift is 12 units down

at X= 0 the function f(x) = 2/6x^3 is not differentiable

Since 1/0 cannot be differentiated and the denominator will become zero when x=O, the function is not defined. Sharp points, cusps, and discontinuities in the graph indicate that a function is "not differentiable." Additionally, it implies that at that same location, we can draw an endless number of tangents. There is therefore no special tangent at that place. Even at x=0, the provided function is not defined. (If you plug in x=0, you get (1/0), which is undefined and leaves you with nothing to do.)) Only after a function is clearly defined at a certain moment do we discuss its continuation. And only if the function is continuous at the place do we talk about differentiability.

Answer: 52900 Naira

Step-by-step explanation:

1) Use the equation A = P(1+r/n)^nt

A = Ammount

(Starting Cash) P = 40,000

(Intrest rate) R = 15%

(Number of periods) n = N/A

(Time) t = 2

2) Make an equation

A = 40,000(1+15%)^2

3) Solve the equation.

A = 40,000(1+0.15)^2

A = 40,000(1.15)^2

A = 40,000(1.3225)

A = 52900

Probability of x successes given the probability p of success on a single trial is 0.0154.

When a process is repeated a certain number of times (for example, in a set of patients), the result for each patient can either be a success or a failure, the binomial distribution model enables us to calculate the probability of witnessing a defined number of "successes." In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p.

Additional charge per hour = $42

The expression is used to calculate the total charge, in dollars, for each repair appointment:

75 + 42h

Let h represent the number of hours Susna works during an appointment.

To find the total charge if Susan works for 6 hours, substitute 6 for h in the expression and evaluate.

Thus, we have:

h = 6

75 + 42h

75 + 42(6) = 75 + 252 = 327

Answers:

================================================

Explanation:

Focus on (4,5) and (4,-4)

The input x = 4 leads to simultaneous outputs y = 5 and y = -4 at the same time. This is not allowed in a function. For a function to be possible, each input x must lead to exactly one y output.

Therefore, this given relation is not a function.

-----------

Domain = set of possible x inputs

Range = set of possible y outputs

The statement "An element from the domain is paired with more than one element from the range" basically means we have an x value paired with more than one y value. Therefore, this statement is true since I mentioned (4,5) and (4,-4) earlier.

Rectangular garden has sides:

width, length, width, length

The perimeter is sum of all the 4 sides.

So, we can say:

84 = 2w + 2l

Where

w is width

l is length

Width is 19.5, so we find length:

84 = 2(19.5) + 2l

84 = 39 + 2l

2l = 45

l = 22.5 feet

Now, area is given by:

Area = length * width

Area = 22.5 * 19.5 = 438.75 sq. ft.

The equation of line passing through (-4, -16) and (5, 2) are y = 2x – 8, y - 2 = 2(x - 5) and y + 16 = 2(x + 4)

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

The standard form for linear equation is:

y = mx + b

Where m is the slope and b is the y intercept

The equation of line passing through (5, 2) and (-4, -16) is:

y - 2 = [(-16-2)/(-4-5)](x - 5)

y - 2 = 2(x - 5)

y = 2x - 8
