Answer:
D. The flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min.
Step-by-step explanation:
Flow rate = 
flow rate of water in the big tank = 
= 60 gallons/minute
flow rate in the smaller tank = 
= 40 gallons/minute
The difference in flow rate between the tanks = 60 - 40
= 20 gallons/minute
Since the two tanks have the same amount of water after the given time, then the volume of water in the large tank decrease; while the volume of water in the small tank increased.
Therefore, the flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min. This shows that option D is correct.
The graph is a straight line graph that has a y-intercept of -300 (0, -300),
and an x-intercept of 30, (30, 0).
- First Part: A Real-Life problem to fit the data is; <u>Elevation of a diving bell</u> from a 300 feet depth at a constant rate.
- Second Part: The domain of the function is <u>continuous</u>.
Reasons:
First Part;
A Real-life Problem to fit the data shown in the GRAPH is the elevation of a
diving bell from a depth of 300 feet below the surface of the water, at a
constant rate of 10 feet per second.
Second Part;
A discrete domain are values of input made up of only particular numbers
contained within an interval, continuous domain are input values that are
made up of all the numbers within an interval.
Given that the graph of the function is a continuous line, and not made up
of a series of dots and that the input value of time can take on any value,
within the domain from 0 to 30 seconds, the domain is a continuous
domain.

Answer:
Step-by-step explanation:
let x=11.510510510...
multiply by 1000
1000x=11510.510510...
again multiply by 1000
1000,000 x=11510510.510510...
subtract
999,000 x=1,1 49 9,000
x=11,499,000/999000=3,833,000/333,000=3833/333
333 ) 3833 (11

If she used rounding properly, she would have gotten -25 x 10 = -250
