Answer: 5 or -100
Step-by-step explanation:
5/20 = 0.25
-100/20 = -5
For this case we have that by definition, the area of a circle is given by:
Where:
r: It is the radius of the circle.
So, we have that the area of the shaded region is given by:
We divide between 4 on both sides of the equation:
We apply root to both sides:
We choose the positive value of the root:
Finally, the value of "x" is 9
Answer:
Answer:
Solution given:
radius [r]=3ft
height[h]=5ft
Volume of cone=⅓*πr²h
$ubstitute value
Volume of cone =⅓*3.14*3²*5=47.1ft²
Volume of cone is 47.1ft²
<u>1. For what numbers the function is null ?</u>, so there is one solution :
<u>2. For what numbers the function is negative ?</u>The function is a parabola<span> </span> <span>upturned (
)</span>, so if its don't cut the abscissa line (0 to 1 solution where the function is null), there is no negative numbers.
Here, there is just one solution who cut the abscissa line, so there is no solution for the negative function.
<span>
The function is never negative</span>.
