the amount of water, A, in thousands of liters, available in a water tank located on a farm fluctuates in a yearly cycle and can be modeled by the function. A(t)=asin(kt)+b where t is the elapsed time, in weeks, since the start of the year. The amount of water available in thank on week 6 is 24 thousand liters and on week 31 is 9.2 thousand litres. Find the value of k, in degrees, assuming there are 52 whole weeks in a year.

line or a linear equation graph

step-by-step explanation:

idk sry

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
