The value of t that makes the factor e^(.032t) have the value of 2 can be found using logarithms.
2 = e^(0.032t)
ln(2) = ln(e^(0.032t)) = 0.032t
t = ln(2)/0.032 ≈ 21.66
It would take 21.66 years for the cost to double.
Answer: 2 1/2 1 1/6 2 2/5
Step-by-step explanation:
Answer:
118%
Step-by-step explanation:
Cora's kitten weighed in the last visit to the veterinarian's office= 550 grams
Right now, Cora's kitten weighs = 1200 grams
Increase in the kitten's weight= 1200 - 550 = 650 grams
Percent increase in weight= 650/550 * 100
= 118.18% = 118%
Hence, there is 118% increase in kitten's weight.
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844

You have to complete the square of (x²+18x+?) as well as for (y²-36y+?)
You will find: (x+9)² + (y-18)² = 36
& this is the standard equation requested
