Using pythagorean theorem :

$a {}^{2} = b {}^{2} + c {}^{2} \\ \\ c {}^{2} = 4 {}^{2} + 6 {}^{2} \\ \\ c {}^{2} = 16 + 36 \\ \\ c {}^{2} = 52 \\ \\ c = \sqrt{52} \\ \\ 7 {}^{2} = 49 \\ \\ 8 {}^{2} = 64 \\ \\ 7 < c < 8$

Find the unit rate 50 min?<br> 20 calls?

ioda

Answer: 2.5 minutes per call

Step-by-step explanation:

This is a fraction equal to

50 minutes ÷ 20 calls

50 minutes ÷ 20

20 calls ÷ 20 = 2.5 minutes/ 1 call

Oil is poured on a flat surface and it spreads out forming a circle. the area of this circle is increasing at a constant rate of

blondinia [14]

Yay

derivitives

everything is taken derivitve in repsect to time

da/dt=10cm^2/s

alright
area=pir^2
da/dt=2pir dr/dt
10cm^2/s=2pir dr/dt
r=10
$\frac{10cm^2}{sec}=2\pi 10cm\frac{dr}{dt}$
$\frac{10cm^2}{sec}=20\pi cm \frac{dr}{dt}$
divide both sides by 20pi
$\frac{10cm^2}{20cm \pi sec}= \frac{dr}{dt}$
$\frac{1cm}{2\pi sec}= \frac{dr}{dt}$

the rate of change of the radius when radius=10 is $\frac{1cm}{2\pi sec}$
