Answer:
see below
Step-by-step explanation:
7^7−7^6
Factor out 7^6
7^6 (7-1)
7^6 *6
This has a factor of 6 so it is divisible by 6
Answer: r + 6
Step-by-step explanation:
Shown in the question, r represents the numbers of marbles that Rory has. Conrad has 6 more marbles than Rory, which means than is r + 6.
Answer:
50 million
Step-by-step explanation:
You don't need to go to the trouble to find the value of k in e^(kt). Rather, you can use the given ratio directly.
When t = years after 1990, the population of 49 million took 12 years to achieve. The estimate desired is for 16 years after the year 1990. The appropriate exponential formula for the population is ...
P = 46·(49/46)^(t/12)
Then for t=16, this is ...
P = 46·(49/46)^(16/12) ≈ 50.04 . . . . million
The population in 2006 is estimated at 50 million.
_____
The form of the exponential equation we used above is ...
f(x) = (baseline value)·(ratio to baseline)^(x/(interval corresponding to ratio))
Answer:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Step-by-step explanation:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Answer:
$ 7,299.92
Step-by-step explanation:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
