What does Direct & Inverse variation mean?

Answers

Answer 1

Answer: In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. ... In inverse variation, it's exactly the opposite: as one number increases, the other decreases. This is also called inverse proportion.

Step-by-step explanation:

Answer 2

Step-by-step explanation: Direct variation is the relationship between two variables such that the variables have a constant ratio, k, were k ≠ 0.

If we call our variables a and b, we can use the

following formulas to represent direct variation.

[tex]\frac{a}{b} = k[/tex] or [tex]b = ka[/tex]

Inverse variation is also a relationship between two variables but the difference is that as one variable increases, the other variable decreases.

Suppose that our variables are g and h.

As g increases, h will decrease or as g decreases, y will increase.

1.83 x 10¹³ + 6.4 x 10¹¹ = 10¹⁰ (1830 + 64)

1.83 x 10¹³ + 6.4 x 10¹¹ = 1894 x 10¹⁰

Step-by-step explanation:

Consider the system of equations in standard form. x + 4y = 26, 3x – 4y = 30 What is the best window range for the x-values to determine the solution? What is the best window range for the y-values to determine the solution? What is the exact solution to the system of equations?

Answers

Answer:  x + 4y = 26 Slope = -0.500/2.000 = -0.250

 x-intercept = 26/1 = 26.00000

 y-intercept = 26/4 = 13/2 = 6.50000

Step-by-step explanation: x + 4y = 26

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 6.500 and for x=2.000, the value of y is 6.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 6.000 - 6.500 = -0.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -0.500/2.000 = -0.250

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x+4y-26  = 0 and calculate its properties

Notice that when x = 0 the value of y is 13/2 so this line "cuts" the y axis at y= 6.50000

 y-intercept = 26/4 = 13/2  =  6.50000

When y = 0 the value of x is 26/1 Our line therefore "cuts" the x axis at x=26.00000

 x-intercept = 26/1  = 26.00000

3x – 4y = 30 Slope = 1.500/2.000 = 0.750

 x-intercept = 30/3 = 10

 y-intercept = 30/-4 = 15/-2 = -7.50000

Notice that when x = 0 the value of y is 15/-2 so this line "cuts" the y axis at y=-7.50000

 y-intercept = 30/-4 = 15/-2  = -7.50000

y = 0 the value of x is 10/1 Our line therefore "cuts" the x axis at x=10.00000

 x-intercept = 30/3  =  10

Answer:

What is the best window range for the x-values to determine the solution?

x-min=-10, x-max = 15

What is the best window range for the y-values to determine the solution?

y-min= 0, y-max = 5

What is the exact solution to the system of equations?

Hello.

To solve this, isolate h, by adding the two numbers.

9 + (-3) = 6

h = 6

Check: 6 - (-3) = 9

This is true because when subtracting a negative number, it cancels out because of double negative, so it becomes 6 + 3 = 9, which is also true.

Find the measure of angle b

Answers

Answer:

130°

Step-by-step explanation:

a straight line is 180°

so you have

180°-50°= 130°

explanation:

b and 50 are supplementary angles (they add up to 180), so create an equation by adding them up to equal 180:

b + 50 = 180

we want the x by itself, so subtract both sides by 50 to get:

b = 130°

Step-by-step explanation:

Mr. Trpkosh was calculating the rate of change of two functions. The first function had a rate of change of -10; the second function had a rate of change of 8. Norman said the second function had the greater rate of change because 8 is greater than -10. Do you agree or disagree with Mr. Trpkosh? Explain your answer. *

Answers

Answer:

No, I do not agree with Mr. Trpkosh.

Step-by-step explanation:

The rate of change of a function means the total change in the function for a unit change in the independent variable.

If the function is increasing with increment in the independent variable, then the rate of change of the function is positive, while if the function is decreasing with the same,  then the rate of change of the function is negative.

Given that the rate of change of the first function = - 10, so this function is decreasing with a rate of 10.

The rate of change of the second function = 8, so this function is increasing with a rate of 8.

So, the first function has a higher rate of change.

Answer:

The differences between a physical change and a chemical change are as follows :

Physical change is a temporary and usually reversible change in which no new substances are formed whereas Chemical change is a permanent and it is usually an irreversible change in which new substances with different properties are formed. In physical change, the chemical composition of the substance remains the same but only the physical properties like state , colour , speed , motion , shape , size etc are changed whereas In chemical change , the physical properties , the chemical properties and the chemical composition of the substances are changed.Physical change is a reversible change as it occurs in forward as well as backward directions whereas chemical change is an irreversible change as it cannot be reversed back from products to reactants.Some of the examples of physical change are glowing of an electric bulb , magnetising an iron nail , preparing a solution , changing of ice into water and water vapour etc. Some of the examples of chemical change are changing milk into curd , rusting of iron , burning magnesium ribbon , decaying grasses , cooking rice etc.

The division of 3/8 by 2/3 is 9/16.

What is Fraction?

Every fraction has a numerator and a denominator separated by a horizontal bar known as the fractional bar.

The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.

We have to divide 3/8 by 2/3

So, 3/8 ÷ 2/3

As, instead of division we proceed with multiplication as

3/8 x 3/2

= 9/ 16

So, the required fraction is 9/16.
