Answer:
<h2>
6.79</h2>
Step-by-step explanation:
According to Question,
Squaring on both sides
Calculate
Let's check :
If we multiply 6.79 by itself, then the result will be approximately 46.
Hope this helps..
Best regards!!
Let the equation representing the function be y = -mx + c; where m is the charge per minute and c is a initial balance.
25.04 = -31m + c . . . . . (1)
19.74 = -64m + c . . . . . (2)
(1) - (2) gives: 5.3 = 33m
m = 5.3/33 = 0.16 (i.e. charge per minute is 16 cents)
From (1), 25.04 = -31(0.16) + c
25.04 = -4.96 + c
c = 25.04 + 4.96 = 30 (i.e. initial balance is $30)
Remaining credit after 85 minutes call is -85(0.16) + 30 = -13.6 + 30 = $16.40
Answer:
1445 mg
Step-by-step explanation:
If you go from 2009 to 2011 and decayed 390 mg, you divide that by two to see how much it decays in one year. After you get that, you multiple 195 by 5 and get 975. your initial value is 480, so you would add 975 and 480 to get the answer 1445 mg. I am only in the 7th grade, so I could be wrong but it looks like a simple slope problem and I feel pretty confident about my answer.
