IRINA_888 [86]3 years ago
5 0

Answer:

fraction

Step-by-step explanation:

If you have a negative exponent, such as x^{-2}, that can also be written as \frac{x^{-2} }{1}

by moving the exponent (and it's base) to the denominator (the other side of the fraction, since it's in the numerator), you make the exponent positive: \frac{1}{x^{2} }

*please help* The points (0, -4) and (3,2) lie on the graph of a linear function. What is the rate of change of the function?
Lubov Fominskaja [6]
Rate of change = slope

slope = )y2 - y1) / (x2 - x1)
(0,-4)....x1 = 0 and y1 = -4 (pay attention to the negative sign when subbing)
(3,2)....x2 = 3 and y2 = 2
now we sub
slope(rate of change) = (2 - (-4) / (3 - 0) = (2 + 4) / 3 = 6/3 = 2 <==

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
