Answer:
It takes at least 7 months for the cat to be at least 6 kg lighter than the original weight.
Step-by-step explanation:
Use exponential decay formula:
A = P (1-r)t
A = amount decreased to
P = original amount
r = rate of decrease
t = time
6 ≥ 12 (1-0.10)t divide both sides by 12
0.5 ≥ (0.9)t take log of both sides
log (0.5) ≥ log (0.9)t power rule of logs lets the exponent t drop to front of log to become a factor
log (0.5) ≥ t log(0.9) divide both sides by log(0.9) which is negative so reverse the inequality sign
log (0.5) / log (0.9) ≤ t use calculator
6.57 ≤ t
It takes at least 7 months for the cat to be at least 6 kg lighter that original weight.
check:
12 (0.9)7≈ 5.73
12 (0.9)6 ≈ 6.37
Answer:
1
Step-by-step explanation:
To evaluate f(g(x)) when x = 5, evaluate g(5) then substitute the value obtained into f(x)
g(5) = 
= 
= 1, then
f(1) = 1² - 3(1) + 3 = 1 - 3 + 3 = 1
(-6,-8) i believe but its difficult without a graph in front of me haha
Hey there!
Answer is 1/870, or in decimal form 0.0011.
Hope this helps. - M
If you would like to know how much will the watermelon cost, you can calculate this using the following steps:
$1.27 ... 1 pound
$c = ? ... 5.5 pounds
1.27 * 5.5 = 1 * c
c = 1.27 * 5.5
c = $6.99
The correct result would be: <span>c = $1.27 * 5.5 pounds = $6.99.</span>
