What was the area covered by the oil slick when Lindsay first saw it (at t = 0)? In the remaining questions, express the rate of growth of the oil slick in square meters per hour.

a. At what average rate did the oil slick grow during the first 2 hours after Lindsay’s initial observation?

b. At what average rate did the oil slick grow during the first half-hour after Lindsay’s initial observation?

c. At what average rate did the oil slick grow during the 15 minutes before Lindsay’s initial observation?

At what rate was the oil slick growing at the instant when Lindsay first saw it?

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

correct answers below:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
