Answer:
2
Step-by-step explanation:
For any positive numbers a,b we always have the following identity:
(gcd(a,b) denotes the greatest common divisor between a and b, and lcm(a,b) denotes the least common multiple between a and b)
In our case, we are given that and that . Plugging that in into our identity, we get:
And so solving for :
Answer:
C = 12π or 37.7
Step-by-step explanation:
A = πr²
36π = πr²
π's get divided out and you are left with:
r² = 36
if you take the square root of 'r' it will equal the square root of 36, which is 6
C = 2πr
C = 2π(6)
C = 12π or 37.7
None!
The triangle inequality requires that the sum of any two sides must be greater than the third. Here 4+5<10, so no triangle can be drawn.
Answer:
Step-by-step explanation:
Let
After one year, in 2001, the price is $a_2$, where
$a_2= a_1-a_1\times (0.15)$
$\therefore a_2=a_1(1-0.15)=a_0(0.85)$
Now after two years, in 2002, let the price be $a_3$
The pattern is pretty clear. After $n$ years, in $200n$ the price will be:
$a_n= a_0(0.85)^{n-1}$
