Step-by-step explanation:
Input:
Input is generally defined as the information that is sent or passed to a computer or the information what is taken. The devices that are used to give or offer such information is know as Input devices.
For example:
We usually use keyboard to type and give a specific data to the computer and hence it can be considered as an Input device.
Output:
Output is generally defined as the source of information that is received or processed by the computer or the information what is given back. The devices that are used to give back such information is know as Output devices.
Example:
Printers takes the input from us,process it and gives back the output in the form of printed sheets,Hence it can be considered as Output device.
<h3>Given</h3>
- C(t) = 40 cm + t·(2/5 cm/s) . . . circumference of a circle vs time
<h3>Find</h3>
- dr/dt for radius r
- r at t=4 seconds
<h3>Solution</h3>
The circumference and radius of a circle are related by
... C = 2πr
so the radius in terms of circumference is
... r = C/(2π)
... r(t) = (40 +0.4t)/(2π) = (1/π)(20 cm + 0.2t cm/s)
Then dr/dt is
... dr/dt = 0.2/π cm/s
And the radius at t=4 s is
... r(4) = (1/π)(20 + 0.2·4) cm
... r(4) = 20.8/π cm
Answer:
yup

Oh man, this is the easiest college level math question that I could find as a middle schooler. I would say 8, but it's probably the wrong answer, so um bye.
Answer:
169.974068
Step-by-step explanation:
12494a-194879=1928777
+194879= +194879
12494a = 2123656
÷ 12494 = ÷ 12494
a = 169.974068
