☻ ~~~~~~~~~~~~ Hello! ~~~~~~~~~~~~~~~ ☻

➴ The correct answer is (x, y) → (x+4, y-3)

On a coordinate plane, going to the right is positive. Going down, is negative.

Answer:

(x, y) --> (x + 4, y - 3)

Step-by-step explanation:

The x value concerns left and right, while the y value concerns up and down. Adding to x makes it move right, and adding to y makes it move up.

Water is flowing into and out of a small reservoir. The total amount of water can be modeled by R, where R(t)=20-15sint^2/25 cub
cestrela7 [59]

9514 1404 393

Answer:

  a) about -1.03 cubic feet per hour

  b) R'(t) = -6/5t·cos(t^2/25); the rate of flow into the reservoir

  c) 0.859 and 5.972 hours

  d) 9.838 hours

Step-by-step explanation:

The rest of the problem statement is in the first attachment. See the second attachment for the graphing calculator input/output.

a) The average rate of change on the interval [0, 8] is ...

  (R(8) -R(0))/(8 -0) ≈ -1.03004 . . . cubic feet per hour

__

b) The derivative can be found using the chain rule.

  R'(t) = -15(2t/25)cos(t^2/25)

  R'(t) = -6/5t·cos(t^2/25)

The derivative of the volume is the rate of change of volume, that is, the flow rate into the reservoir.

__

c) To find the time values when R' = 'average rate of change', we defined the constant a1 to be that average rate of change. The graphing calculator shows the curve R'(t)-a1, which has zeros at the times of interest. The times for which the instantaneous rate of change equals the average rate of change are t = 0.859 and t = 5.972 hours.

__

d) The time of interest is beyond the domain of the function. We cannot use the given function to determine the time of interest.

However, if we extend the domain to include the time of interest, we find it is t = 9.838 hours.

jeyben [28]
Answer is very straightforward:
If you got 49 students and require at least 9 square feet of floor space for each of them, the total minimum floor space you need would be: 49 x 9 = 441 square ft.

Hope it helps!

The relationship between sets of rational numbers is pictured below
REY [17]

The correct answer is G. Integers include whole numbers and natural numbers.

Explanation:

The graph presented shows the relationship between different sets of numbers. In this graph, the second most general category is integers, and this covers or includes two smaller categories which are whole numbers and natural numbers. This means the whole and natural numbers are part of integers.

Indeed, integers include numbers such as 10, 256, or -6 because these can be expressed without using fractions or decimals. Also, this category includes whole or non-decimal numbers, as well as natural numbers, which are positive whole numbers such as 36 or 1546. According to this, the correct answer is G.
