Answer: Third option.
Step-by-step explanation:
<h3>
The exercise is actually: "Identify the variation as direct, inverse, joint or combined: 
"</h3><h3>
</h3>
For this exercise it is important to remember that, by definition, a Joint variation is that variation in which one variable depends on two or more variables and there are a direct relation between these variables.
In this case, you have the following equation given in the exercise:
Let's assume that "r" and "h" are variables.
You can identify that:
- The variable "V" depends on the variables "r" and "h".
- The variables are related directly.
So, based on this, the variation can be read as:
<em>"V" varies jointly with the square of "r" and "h".</em>
Therefore, you can conclude that the given variation is: Joint.
Answer:
0.3
Step-by-step explanation:
By definition: 30% = 30/100 = 0.3
Answer:
Y = 3x^x is a graph that has exponential growth while y = 3^-x has exponential decay.
Y = 3x^x (-∞, 0) and (∞, ∞).
Y = 3x^-x (-∞, ∞) and (∞, 0).
Step-by-step explanation:
The infinity symbols were being used to represent the x and y values of each graph. I will call y = 3^x "graph 1" and y = 3^-x "graph 2".
When graph 1 had positive ∞ for its x value, its y value was reaching towards positive ∞. When its x was reaching for negative ∞, its y was going for 0.
For graph 2, however, when its x was reaching for positive ∞, its x was reaching for 0. When its x was reaching for negative ∞, its y was going for positive ∞.
Here's an image of the graphs:

Answer:
7 ft
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr
The curved portion of a semicircle will be ...
C/2 = (2πr)/2 = πr
The straight portion of the semicircular shape will be the diameter, or 2r. That means the total perimeter of a semicircular shape is ...
P = πr +2r = r(π+2)
Then the radius is ...
r = P/(π+2) = (35.98 ft)/(3.14+2) = 7 ft
The radius of the patio is 7 ft.
