How can you determine which variable is dependent and which variable is independent

MrBillDoesMath!

Answer:  The dependent variable depends on another variable for its value. For example, if  y = 2x,  setting x = 1 forces y= 2.; setting x = 10, forces y =20.  There are no other possibilities for y once x ids chosen. So y is the dependent variable and x is the independent one. You can pick values for the independent variable (x) but no so for the dependent one.

This is actually quite a deep-going question. To truly determine which variables (in an experiment, or in an observation of nature) depend of other variables is sometime very difficult and laborious. In math this may be easier. See detail below.

In pure mathematics, where variables do not necessarily carry a physical meaning, the determination is a matter of definition. A variable is defined to be dependent on another variable, for instance, y depends on x via the specific function, y = 10x + 10. The key is: this is given. Otherwise (if it were not given), suppose I gave you an equation a+b=10 and not told you which is the dependent and which the independent variable. You could think of each being either: a=10-b and b=10-a. Without this being defined, there is no clear way to determine dependency.  

In science, on the other hand, the determination is made based on experimental design and based on certain plausible assumptions about natural dependencies. For example, if you design an experiment to measure some physical quantity, such a height of an individual, you can look at the that as a variable dependent on other variables, such as age, ie., what is the average height of a person given their particular age (say, 0, 1, 2,..., 18 years of age). It would be more of a stretch to measure the age as dependent variable of height.

I hope these thoughts are helpful.

Answer:

7.2 million dollars

Step-by-step explanation:

The domain of the function the complete set of possible values of the independent variable. In this case the domain includes all real numbers except 189.

From;

T(p) = 0.50 (p - 189)

When p = 203.4 million dollars

T(p) = 0.50 (203.4 - 189)

T(p) = 7.2 million dollars

Integral of cosecx dx =log|tanx/2| show that.​
Pie

ANSWER:

Let t = logtan[x/2]

⇒dt = 1/ tan[x/2] * sec² x/2 × ½ dx

⇒dt = 1/2 cos² x/2 × cot x/2dx

⇒dt = 1/2 * 1/ cos² x/2 × cosx/2 / sin x/2 dx

⇒dt = 1/2 cosx/2 / sin x/2 dx

⇒dt = 1/sinxdx

⇒dt = cosecxdx

Putting it in the integration we get,

∫cosecx / log tan(x/2)dx

= ∫dt/t

= log∣t∣+c

= log∣logtan x/2∣+c where t = logtan x/2

Determine the slope of the line 5x + 3y + 12 = 0 .
vazorg [7]
Put ur equation in y = mx + b form because the slope will be in the m position.

5x + 3y + 12 = 0
3y = -5x - 12
y = -5/3x - 4

y = mx + b
y = -5/3x + (-4)......as u can see, the number in the m position (the slope) is -5/3 <===

Explain how to estimate the lateral area of a right cone with radius 5 cm and slant height 6 cm. Is your estimate an underestima
Iteru [2.4K]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The lateral area of a cone is equal to

LA=\pi rl

where

r is the radius of the base

l is the slant height

we have

r=5\ cm

l=6\ cm

assume \pi =3.14

substitute the values

LA=(3.14)(5)(6)=94.2\ cm^{2}

This value is an underestimate, because the assumed pi value is less than the real value

assumed value \pi =3.14

real value \pi =3.1415926536...
