Hey there! :)

Answer:

First option: As x⇒ ∞ f(x) ⇒ -∞.  As x⇒ -∞ f(x) ⇒ ∞.

Step-by-step explanation:

Rearrange the equation:

f(x) = -x³ - 2x² + 1

This is a negative cubic function. The function decreases over the interval

(-∞, ∞). Therefore:

As x⇒ ∞ f(x) ⇒ -∞.

As x⇒ -∞ f(x) ⇒ ∞.

This is the first option.

Suppose you buy a phone for $200 and its value depreciates linearly. If the phone is worth $115 after four years, then what is t
vredina [299]

Answer:

$72.5

Step-by-step explanation:

  • Initial value = $200
  • Depreciated value after 4 years = $115

<u>Since depreciation rate is linear, then:</u>

  • 200 - 4x = 115
  • 4x = 200 - 115
  • 4x = 85
  • x = 85/4
  • x = 21.25

<u>Value after 6 years:</u>

  • 200 - 6*21.25 = 200 - 127.5 = $72.5

The probability that all marbles are yellow is
(7/20) (7/20) (7/20) = 343/8000

We are given
x = 2 and 3
u = 2.5
s = 0.5

Getting the z score
z = (2 - 2.5) / 0.5 and (3 - 2.5)/ 0.5
z = -1 and 1
The percentage is
