Answer:
45
Step-by-step explanation:
Use the geometric sum formula for in infinite sum. 20 terms of this basic formula is close enough The 20th term is 8.6 * 10^-10 which means this goes out to a number with 9 zeros after the decimal and before the 8.
Put another way, the tenth number of this series is the only one affected.
When you use a spreadsheet, it seems to know that the answer is 3/2 as the solution to the sum.
Solution.
Sum = a / (1 - r)
a = 1
r = 1/3
Sum = 1 / (1 - 1/3)
Sum = 1 // 2/3
sum = 3/2
Now you can worry about the 30.
30 * sum(1/3)^n = 30* 3/2 = 45

Answer:
-23.18, -0.82
Step-by-step explanation:
- h² + 24h + 19 = 0
- h²+2h*12+12²-125=0
- (h+12)²-√125²=0
- (h+12+11.18)(h+12-11.18)=0
- (h+23.18)(h+0.82)=0
- h+23.18=0 ⇒ h= -23.18
- h+0.82=0 ⇒ h= -0.82
Answer:
49mg
Step-by-step explanation:
let's call every 7 mg of fever reducer a "dose"
Divide the weight of Greg by the weight per "dose"
42/6 = 7 doses
Each "dose" is 7mg. Multiply the number of doses by 7mg.
7 dose X 7mg = 49mg
Therefore, if Greg weighs 42kg, the pediatrician will prescribe 49mg of fever reducer.
