Step-by-step explanation:

The mean is the average of the data set.

(14+62+35+38+58+46+62)÷7=

(76+35+38+58+46+64)÷7=

(111+38+58+46+64)÷7=

(149+58+46+64)÷7=

(207+46+64)÷7=

(253+64)÷7=

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 9 sin(xy), (0, 8)
malfutka [58]

Answer:

The magnitude is  \Delta f(0,8)  =  72

The  direction  is  i i.e toward the x-axis

Step-by-step explanation:

From the question we are told that

   The function is  f(x, y) =  9sin(xy) \ \ \

    The point considered is  (0,8 )

Generally the maximum rate of change of f at the given point and the direction is mathematically represented as

            \Delta f(x,y) =  [\frac{\delta  f(x,y)}{\delta x } i + \frac{\delta  f(x,y)}{\delta y } j  ]

             \Delta f(x,y) =  [\frac{\delta  (9sin(xy))}{\delta x} i  + \frac{\delta  (9sin(xy))}{\delta y} i   ]

            \Delta f(x,y) = [9y cos (x,y) i +  9xcos (x,y) j]

At  (0,8 )

            \Delta  f (0,8) =  [9(8) cos(0* 8)i  + 9(8) sin(0* 8)j  ]

            \Delta  f (0,8) = 72 i

3. Which temperature during the week is the closest to 0? Explain how you decided this using absolute value.
Katen [24]

Answer:

The closest temperature to zero during the week is -0.5 °F because it's absolute value, 0.5, is smaller than the other numbers.

The farthest temperature from zero during the week is 5 °F because it's absolute value, 5, is the highest out of all the other numbers.

Answer: The coldest temperature would be -4 °F, because it is the farthest number on the left side of zero on the number line.15-May-2020

The warmest temperature would be 5 °F, because it is the farthest number on the right side of zero on the number line.
