Answer:
7c + 668 > 2000
Step-by-step explanation:
Given that :
Target = more than. 2000 food cans
Amount already collected = 668 food cans
Food can remaining to collect per day within 7 days = 2000 - 668
Let number of cans left to collect per day with 7 days = c
7 * c + cans already collected > target
7c + 668 > 2000
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.
Answer:
2/27
Explanation:
• Number of green marbles = 2
,
• Number of blue marbles = 4
,
• Number of yellow marbles = 3
Total = 2+4+3 =9
• Probability of choosing a green marble = 2/9
,
• Probability of choosing a yellow marble = 3/9
Therefore, the possibility that the first marble is green and the second is yellow is:
2/3 hour = 20 minutes. so therefore 20 / 5 = 4 x3 = 12
3/5 of that time is 12 minutes.
