Step-by-step explanation:
Here are some steps to help you
Step 1
4x-3≥13 We are going to be simplifying
Step 2
4x-3≥13 Add 3 to the sides
4x≥16
Step 3
4x≥16 Divide them sides by 4
x≥4
So therefore your answer is x≥4

A rectangle is made of two right triangles then a rectangle inscribed in a circle must have its diagonal as the diameter of the circle. Hope this helps
Calculus 1?
To find concavity you must take the second derivative.
As you would to find your local maximums and minimums (critical points) in the first derivative by setting y' = 0, to find points of inflection you set acceleration, y" = 0.
Now that you know where the point in which the function is neither concave up or concave down (at the points of inflection) plug x-values between them into the second derivative for x. If y" is positive between those particular points will be concave up and if y" is negative it will be concave down between that interval.
For a better understanding you might find a good video on Youtube explaining this if you search "Points of Inflections" or "Concavity of a function".
Cheers.
