De las siguientes relaciones entre dos variables, razona cuáles son funcionales y cuáles no: a. Edad – altura de la persona a lo
Arte-miy333 [17]

Answer:

In this problem, we need to describe the relation between variables, if that relation is functional or not. It's important to say that we assumed that the first variable is independent, and the second is dependent.

<h3>(a)</h3>

Age - Height of the person along his life: These variable are functinal and make total sense, because through time the person grows, which means the height changes as the age increases. These variables have a proportional relationship.

<h3>(b)</h3>

Height - Age of the person: These relation is not functional, becasuse age can't be a dependent variable, beacuse the age of a person doesn't depends on his height.

<h3>(c)</h3>

Gasoline price - Day of the Month: These relation is not functional, becasue time must be the independent variable.

<h3>(d)</h3>

Day of the Month - Gasoline price: These realation make sense, beacuse the price of the gasoline can be depedent of the day of the month.

<h3>(e)</h3>

A number and its fifth part: Notice that the fifth part depends on the number, it's defined by it, so this can be a function.

<h3>(f)</h3>

A number and its square root: These two variables represent a function, where "a number" represents the domain value and "its square root" represents a range vale.

Find the volume of a right prism with height h=10 cm, if :
kozerog [31]

Answer:

Step-by-step explanation:

          So, to begin the altitude of a triangle is the line segment that starts at the top vertex and ends at the base of the triangle forming a right angle. If we want to find the volume of the of the prism the formula is Ab*h. This is the area of the base, times the height of the prism. This is true because a simple expination of volume is a box filled with stuff. To count how much stuff we have in the box the formula uses layers. Volume is just like a lot of 2 dimential areas stacked on top of each other. So taking the area of the flat base and puting it on top of it self 10 time will give you the same prism thats in the problem. Now we just have to apply the consept. Since the base is a triangle and we need to find the area. The formula is b*h*1/2. Base time height times 1/2. The reason for this is also simlar to area. A triangle is half of a square, so to find the area of a square the formula is L*W. Since a triangle is half of a square you just multipuly it by 1/2. When solved you will get 4*3.5*1/2=7, the area of the base is 7 cm^2. Now appling the topic above we stack the base 10 times, so 7*10=70. In conculstion the volume of the prism would be 70 cm^2.

Georgina knows the inequality is true, but she cannot remember what number is in the denominator.
stealth61 [152]

Answer:

<h3>D. 12</h3>

Step-by-step explanation:

Which number could be the missing number?

Given the inequality expression, 1/10 > 1/ ?

We are to fine the missing number that will make the inequality true;

Cross multiply:

1 * x > 1*10

x > 10

Hence the value of x greater than 10 is the answer. From the options, the only value greater than 10 is 12. Hence 12 is the correct answer.
