Answer:
[tex]x=2.3\text{ only }[/tex]
Step-by-step explanation:
We are given the second derivative:
[tex]g^\prime^\prime(x)=0.1x^5-0.29x^4-0.694x^3+1.9136x^2[/tex]
And we want to find the values for -3 < x < 4 in which the graph of g has a point of inflection where the concavity changes from concave up to down.
First, recall that inflection points occur whenever g''(x) = 0 or is undefined.
And that:
g is concave up for an interval if g''(x) > 0 for that interval. g is concave down for an interval if g''(x) < 0 for that interval.Graphing the function (please refer below for the graph), we can see that g''(x) has an inflection point at x = -2.6, 0, 2.3, and 3.2.
If g''(x) changes from concave up to concave down, the values before and after that inflection point must be positive and then negative.
We can see that g''(x) is only positive for the values before the inflection points at x = 0 and x = 2.3.
However, for values after the inflection points, only x = 2.3 becomes negative.
Therefore, since at x = 2.3, the graph changes from positive to negative, this is where the graph of g changes from concave up to concave down.
Notes:
For the point x = 0, the graph stayed positive both before and after x = 0.
Therefore, g does not have an inflection point at x = 0.

What is the volume of a rectangular prisim with the following dimensions?
Length= 4
Width= 3
Height= 10
Answers
Answer:
120
Step-by-step explanation:
so volume = l*w*h
= 120
if my answer helps please mark as brainliest.
Answer:
120³
Step-by-step explanation:
Hi!
This is very easy you just need to know the formula for finding the area of a rectangular prism. I attached something to help you with that but I also have an explanation.
The formula to find the area of a rectangular prism is L x W x H,
or in full words Length x Width x Height.
So now lets see what the problem has given us so we can plug things in.
Length = 4
Width = 3
Height = 10
Wow, it gives us all of it!
So now we just have to plug these numbers into the equation and solve.
So :
Length x Width x Height
4 x 3 x 10
Now we solve it :
4 x 3 = 12
And then we take 12 and multiply it by the last 10 in the equation.
12 x 10 = 120
And that is your answer, the volume of the rectangular prism!
Make sure to add a ³ after the 120 like so :
120³
This tiny 3 represents volume in math since the shape is 3D.
And if there are units of measurement involved like feet or inches make sure to put that in there as well like so :
120 feet³
I hope this helps!
