How do you determine if any real-world situation is either independent variable or dependent variable?

In determining if any real-world situation is either an independent variable or dependent variable depends on factors that might have been taken into consideration as to the situation per se and the situation before it happened and the situation to take place. As an anonymous person quoted, "all things are connected", this gives us a universal idea that a situation in the real-world can be both an independent and dependent variable, depending on how it is looked upon and/or how it is treated. A landslide, for example, might be an independent variable since there was no direct factor that caused it, it just happened. On the other hand, it becomes a dependent variable if it happened while it was raining or amidst a storm or it happened right after.

Which of the following statements is true?. . A.A tangent is never a secant.. B.A secant is always a chord.. C.A chord is always

skelet666 [1.2K]

The correct answer is:

A) A tangent is never a secant.

Explanation:

A tangent is a line that touches a circle in exactly one point. A secant is a line that touches a circle in two different points.

Since a tangent only touches once and a secant touches twice, there is no way a tangent can be a secant.

Answer:

$21 in^{2}$

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. 9.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

$A=bh\frac{1}{2}$

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply that by 4. 12.

Add 12 and 9 together, and you get:

$21 in^{2}$

I hope this helps!

ABC ~ ADE AC = 4, AE = 7, AD = 10, what is the length of AB? 1 3/7 2 1/2 5 5/7 17 1/2

Butoxors [25]

If the polygon or the figures are similar then it is known that the ratios of their corresponding sides and angles are proportional. In this item we can derive an equation that is,

AC/AE = AD/AB

Substituting the known values,

4/7 = 10/AB

AB from the equation is equal to 70/4 or equal to 17 ½.
