Consider the two exponential equations shown. Identify the attributes for each equation to complete the table.

SIZIF [17.4K]

Answer:

$y = 2 5 0 ( 0 . 8 9 ) ^ x$

Initial value: 250

Decay

Decay rate: 11%

$y = 4 0 ( 1.11 ) ^ x$

Initial value: 40

Growth

Growth rate: 11%

Step-by-step explanation:

The function we have on the left of the table is:

$y = 2 5 0 ( 0 . 8 9 ) ^ x$

Initial value (when x = 0): $y = 2 5 0 ( 0 . 8 9 ) ^ 0$

y = 250 (initial value)

Growth or Decay: 0.89 < 1 so decay

Decay rate: (1 - 0.89) * 100 = 11%

Function on right side:

$y = 4 0 ( 1.11 ) ^ x$

Initial value (when x = 0): $y = 4 0 ( 1 . 1 1 ) ^ 0$

y = 40 (initial value)

Growth or decay: 1.11 > 1 so growth

Growth rate: (1.11 - 1) * 100 = 11%

Consider the data set

Serhud [2]

Answer: 3.496

Explanation: You find the mean, which is 57.714. Next, you subtract the mean from each number in the dataset, |55 - 57.714|, |59 - 57.714|, etc. You then add all of those numbers together and divide them by the amount of numbers like you would determining the mean. This gives you 3.496. Also sorry for taking so long to respond I’m on my phone and cannot type as fast as I would on pc.

Option C. 50 square centimeters

Step-by-step explanation:

we know that

The surface area is equal to the area of four triangles plus the area of rectangle

$SA=2[\frac{1}{2}(4)(2)]+2[\frac{1}{2}(6)(3)]+(6)(4)$
