Write a function where y should vary directly with x, then give a real world example for it.

Answers

Answer 1

The function to represent a direct variation relationship between y and x is y = kx.

How to write a function where y should vary directly with x?

A direct variation relationship is one where the ratio of two quantities is always constant. In mathematical terms, if y varies directly with x, then there is a constant k such that y = kx.

Below is a function to represent a direct variation relationship between y and x:

y = kx

where k is the constant of proportionality.

A real world example of a direct variation relationship is the relationship between the distance traveled by a vehicle and the time it takes to travel that distance.

If a car travels at a constant speed, then the distance it travels is directly proportional to the time it takes to travel that distance. In mathematical terms, we can write:

distance = rate × time

where the constant of proportionality (rate) is the speed of the car.

True or False: the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring.

Answers

It is false that the probability of the union of two events can be more than the probability of the intersection of the two events occurring.

This is because when two events intersect, the intersection of the two events refers to the occurrence of both events at the same time, while the union of the two events refers to the occurrence of either event or both events at the same time. therefore, the union of two events can have a higher probability of occurring than the intersection of two events since the union includes the possibility of both events occurring, while the intersection does not.

For example, let us consider two events, A and B. Event A has a probability of 0.3, and event B has a probability of 0.4. The probability of the intersection of these two events is 0.12(0.3 X 0.4) while the probability of the union of these two events is 0.7(0.3+0.4-0.12). As seen in this example, the probability of the union of two events (0.7) is greater than the probability of the interaction of two events(0.12)

Graph the linear system and tell how many solutions it has. If there is exactly one solution, estimate the solution and check it algebraically.

Answers

Answer:

There is exactly one solution: (1, 2).

Step-by-step explanation:

For this, it's already in slope intercept form so all you have to do is graph the two and see at what point do these two lines cross, which is (1, 2).

Hope this helps!

Once you graph the equation, you can estimate the solution point is at (1,2)

you can then set the two equations as being equal to each other and plug in this point:

y -x -1 = y + x -3

(2) -(1) -1 = (2) + (1) -3

what is 192kg in lbs?

Answers

The pound is defined as 453.59237 grams. Using the formula to convert pounds to kilograms, you find that 192 kilogram equals 87.0897 pound.

We know that:

1 lb = 1 kilogram, 2 lb = 4.40925 kilogram, 12 lb = 26.4555 kilogram.

Therefore, 192 lb = 87.0897 kilogram.

Kilogram:

The kilogram (symbol: kg) is the basic unit of mass in the International System of Units (SI). It is currently defined in terms of a fixed value of Planck's constant h equal to 6.62607015 × 10-34 in units of J s or kg m2 s-1. The meter and second are defined by c, the speed of light, and ΔνCs, the frequency of cesium. Although the definition of the kilogram changed in 2019, the actual size of the unit has remained the same. The changes are aimed at improving the definition of SI base units rather than changing how they are used worldwide.

Pound:

The pound (symbol: lb) is a unit of mass used in both the British and American systems of measurement. The international reserve pound (the common pound used today) is defined as exactly 0.45359237 kilograms. An avoirdupois pound equals 16 avoirdupois ounces.

According to the Question:

To convert 192 lbs to kg multiply the mass in pounds by 0.45359237.

The 192 lbs in kg formula is [kg] = [192] × 0.45359237.

Thus, for 192 pounds in kilos we get:

192 lbs to kg = 87.09 kg

192 lbs in kg = 87.09 kg

192 pounds to kg = 87.09 kg

192 pounds to kilograms is 87.09 kg.

what is 23.5 cm to inches ?

Answers

1 cm is defined as 1/100 of a meter. One foot is defined as 1/3 of a yard or 12 inches in length. We know that, 1 inch = 2.54 cm and therefore, 23.5 centimeter = 9.252 inches

Centimeters :

The centimeter (cm) is the fractional part of the meter, the international standard unit of length, and equals approximately 39.37 inches. It is defined as 1/100 of a meter.

The centimeter is based on the SI unit of measurement and is equal to one hundredth of a meter as indicated by the prefix "centi". The metric prefix ranges from 10-18 to 1018 in decimal, and the base (metric in this case) has no prefix and a modulus of 1. Exploring the most commonly used metric prefixes such as kilogram, mega, giga, tera, centi, milli, micro, and nano can be useful for quickly navigating metric units.

Inch:

Inches is a unit of length or distance in several systems of measurement, including traditional American units and British Imperial units. An inch is defined as 1/12 of a foot, so 1/36 of a yard. By modern definition, 1 inch equals 25 exactly 4 mm.

The term "inch" comes from the Latin unit "uncial", equivalent to "1/12" in Roman terms. There were several standards for inches in the past and the current definition is based on international yards. One of the earliest definitions of an inch was based on a barley grain, where an inch equals the length of three dry round grains of barley laid end to end. Another version of the inch is believed to be derived from the width of a person's thumb, where length was obtained by averaging the widths of three thumbs (small, medium, and thumb).

By multiplying  the value in centimeters by the conversion factor 0.3937007874021.

So, 23.5 centimeters = 23.5 × 0.39370078740213

The triangles are similar so the sides are proportional.

It is important to match the sides correctly.

Triangle PQR is similar to Triangle STU

So the sides PQ similar to ST

QR similar to TU

PR similar to SU.

We are given one side in the smaller triangle SU which is 6.

SU matches to PR - if you divide PR by SU - 21 ÷ 6 = 3.5

So the sides of the smaller triangle are 3.5 times smaller

PQ = 14 then divide by 3.5 to get ST = 4

QR = 28 then divide by 3.5 to get TU = 8

The angles are much easier.

Similar triangles have the same angle measurement.

Find the corresponding angles.

To find ∠Q - add angles P and R and subtract from 180°.

All triangles interior angles add to 180°.

180 - (70 + 46) = 180 - 116 = 64°

Match up the corresponding angles:

∠S = 70°, ∠T = 64°, ∠U = 46°

SU = 6   ST = 4  TU = 8

If we change the constraint quantity to a value outside the range of feasibility for that constraint quantity, the shadow price will change.
True or False

Answers

Yes, it is True. If we change the constraint quantity to a value outside the range of feasibility for that constraint quantity, the shadow price will change.

The shadow price is the marginal value of the constraint quantity, and it represents the increase in the objective function per unit increase in the constraint quantity. If the constraint quantity is changed to a value outside the range of feasibility, the shadow price will change because the relationship between the objective function and the constraint quantity has changed. The change in shadow price will depend on how the constraint affects the objective function, but it is typically that the shadow price will increase as the constraint becomes more binding.

What is function?

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the codomain or range) with the property that each input is related to exactly one output. In other words, a function is a rule or a mapping that assigns a unique output value to each input value. Functions can be represented in various ways, such as equations, tables, graphs, or diagrams. They are used to describe and model a wide range of phenomena in mathematics and other fields, such as physics, engineering, economics, and social sciences. Functions are often denoted by symbols such as "f(x)", "g(x)", or "h(t)" and can be composed or combined to form new functions. They can also be classified according to various properties, such as whether they are continuous, differentiable, invertible, or periodic. In summary, in mathematics, a function is a relation between a set of inputs and a set of possible outputs that assigns a unique output value to each input value.

Here,

To find the x-coordinates of the points where the proton crosses the x-axis, we need to find the roots of the function f(x) = x⁴ - 2x² - 15. These are the values of x that make the function equal to zero, which correspond to the points where the proton crosses the x-axis.

To find the roots, we can use the factoring method or the quadratic formula. In this case, we can factor the function as follows:

f(x) = x⁴ - 2x² - 15

= (x² - 5)(x² + 3)

Setting each factor equal to zero and solving for x, we get:

x² - 5 = 0 or x² + 3 = 0

Solving for x in each equation, we get:

x = ±√(5) or x = ±i*√(3)

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b

or [tex]\dfrac{a}{b}[/tex]

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Given that;

The ratio of two angle = 11:19

The angles are supplementary

Now,

Let the angles be 11x and 19x.

x=180/20

x=9

The measure of angles;

11x= 99

19*9=171

Therefore, by the given ratio the answer will be 99 and 171.

A scientist conducts an experiment on the growth of a certain bacteria culture.
The variable t represents the number of hours since the beginning of the experiment.
When t=0 (that is, at the beginning of the experiment), there were 50 bacteria in the culture.
Every 1 hour, the number of bacteria in the culture increases by a factor of 2.
The number of bacteria in the culture, N, can be modeled as a function of t by an exponential growth function N (t).
(Recall that an exponential growth function N (t) is a function of the form N(t)= ab', where a and b are positive constants.)

Answers

The exponential equation is N ( t ) = a ( b )^t , where a = 50 and b = 3

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the number of bacteria in the culture at a given time be N ( t )

The culture increases by a factor of 2

So , the value of r = 200 % , r = 2

Now , when t = 0 , the number of bacteria in the culture N ( 0 ) = 50

So , the exponential equation is

N ( t ) = N ( 0 ) ( 1 + r )^t

Substituting the values in the equation , we get

N ( t ) = 50 ( 1 + 2 )^t

N ( t ) = 50 ( 3 )^t

On simplifying the equation , we get

N ( t ) = a ( b )^t , where a = 50 and b = 3

Hence , the exponential equation is N ( t ) = 50 ( 3 )^t

Why is it important to understand graphs that represent exponential equations? What is one example of seeing an exponential pattern in everyday life?

Answers

Yet, the equation is typically insufficient on its own. We can understand a lot by looking at their visual representations, which is why graphing exponential equations is a useful tool. It offers us even another level of understanding for forecasting upcoming events.

What is exponential equation?Another instance of exponential growth in the real world is weed growth. The nutrients from the desirable plants are eaten by weeds as they spread and flourish. Following the exponential growth trend, they expand quickly. A mathematical function termed an exponential function has the formula f (x) = ax, where x is a variable and a constant called the base of the function, which must be greater than 0. The transcendental number, or e, which is roughly equivalent to 2.71828, is the most often used exponential function basis.Bacterial growth is a prime example of an exponential function. Every hour, some germs multiply by two.
