Answer:
Relative Extrema: \left(\frac{2}{\sqrt{e}},-\frac{6}{e}\right)
Step-by-step explanation:
There is only one extreme minimum point that is \left(\frac{2}{\sqrt{e}},-\frac{6}{e}\right) and there is no any point of reflection for this function.
You can find it in attached pictures of graphs.

Answer:
π square inches
Step-by-step explanation:
The area of the whole circle is ...
A = πr²
A = π(2 in)² = 4π in²
A 90° sector is 1/4 of the circle, so its area is ...
(1/4)(4π in²) = π in²
The expression for the kinetic energy is mass times velocity squared over two
For the first question that gives us 2,25 joules
If the ball is at the given height then it has a further 60 Joules in potential energy.
Answer is D
1. We assume, that the number 9.375 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 9.375 is 100%, so we can write it down as 9.375=100%.
4. We know, that x is 7.25% of the output value, so we can write it down as x=7.25%.
5. Now we have two simple equations:
1) 9.375=100%
2) x=7.25%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
9.375/x=100%/7.25%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 7.25% of 9.375
9.375/x=100/7.25
(9.375/x)*x=(100/7.25)*x - we multiply both sides of the equation by x
9.375=13.793103448276*x - we divide both sides of the equation by (13.793103448276) to get x
9.375/13.793103448276=x
0.6796875=x
x=0.6796875
now we have:
7.25% of 9.375=0.6796875
