A pan of water evaporates at a rate of 0.5 liter every two hours. After two hours, Callidora begins making a graph of the volume remaining in the pan over time (see figure). After 6 hours, the pan is completely dry. C
Time thours)
Which part of the graph can be used to determine the starting volume of water?
Apart D, which shows the x-intercept
B. part A, which shows the intercept
c. part B, which shows the initial value
D. part C, which shows the slope of the line

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

you need to give us more information since we can't answer

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

it has to have an angle of 90 degrees
