A circular oil slick is expanding at a rate of 3m/min. How fast is the area of the oil slick changing when the diameter is 48 me
olga55 [171]

Answer:

48\pi \:m/min

Step-by-step explanation:

Diameter = 48 m

Therefore radius r = 48/2 = 24 m

Area  \: of \:  circular  \: oil  \: slick  \\ A = \pi {r}^{2}  \\  differentiating \: w \: r \: to \: t \: on \: \\  both \: sides \\  \\  \frac{dA}{dt} =  \frac{d}{dt} (\pi {r}^{2} )\\  \\  \frac{dA}{dt} =\pi  \frac{d}{dt} {r}^{2} \\  \\  \frac{dA}{dt} =\pi  \times  2{r}\\  \\  \frac{dA}{dt} =2\pi {r} \\  \\   \bigg(\frac{dA}{dt} \bigg)_{r=24} =2\pi \times  {24} \\  \\   \bigg(\frac{dA}{dt} \bigg)_{r=24} =48\pi  \: m \: per \: min

How many solutions does this equation have?<br><br> –10q = –10q − 7
Salsk061 [2.6K]

Answer:

None (no solutions)

Step-by-step explanation:

-10q=-10q-7 (add 10q to both sides to get the costant 7 by itself)

-10q+10q=-10q+10q-7

0=-7 ( zero will never equal -7 hence there are no solutions to this equation)
