Step-by-step explanation:
Answer:
f(x) = 0.69 (1.03)^x
in other words TO THE POWER x
that would be 0.69 when x = 0 years, now
0.69 * 1.03 after one year
0.69 * 1.03 *1.03 after two years
0.69 *1.03*1.03*1.03 after 3 etc
It is getting bigger. Every year you increase by .03 x which is 3%
B
the ratio is for example
10406.04/10303.01
= 1.01
check:
10303.01/10201 = 1.01 sure enough
so that is increasing by ONLY ONE percent per year
Answer:
= (7 + s) + ( 2 × q )
I'm pretty much sure that this is correct.
Total number of marbles = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12
P(not red) = 12/20 = 3/5

Answer: 3/5
Answer:
x = -1.5625
Step-by-step explanation:
Solve for x:
-8 x - 12.5 = 0
Add 12.5` to both sides:
(12.5 - 12.5) - 8 x = 12.5
12.5 - 12.5 = 0:
-8 x = 12.5
Divide both sides of -8 x = 12.5 by -8:
(-8 x)/(-8) = 12.5/(-8)
(-8)/(-8) = 1:
x = 12.5/(-8)
12.5/(-8) = -1.5625:
Answer: x = -1.5625
