What is the minimum value of F(x)= 10x^{2} -6x-3 3/10 or -39/10
1 answer:
Answer: 3/10
Step-by-step explanation:
Take the derivative of to get
. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.
Now do:
There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.
Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value

Answer:
degrees.
rad or
rad
Step-by-step explanation:
Let's start writing some equivalences.
1 degree = 60 minutes = 60'
1 minute = 1' = 60 seconds = 60''
Therefore,
1' = 60'' ⇒ 60' = 3600'' ⇒ 1 degree = 3600''
For a = 3 degree 5'17'' we are going to transform the minutes and the seconds into degrees.
60' = 1 degree ⇒
5' = degree
For the seconds :
3600'' = 1 degree ⇒
17'' = degree
Finally :
degrees
degrees.
For radians, the equivalence is :
360 degrees = 2π rad
For a = 3.0881 degrees ⇒
360 degrees = 2π rad
3.0881 degrees = rad
rad
or in terms of π ⇒ rad
