Answer:
12.12%
Step-by-step explanation:
We have that the formula is given by:
A = p * e ^ (r * t)
From here, we know that A = 200000; p = 20000 and the time we can calculate 40 - 21 = 19
if we replace we have:
200000 = 20000 * e ^ (19 * r)
we must calculate r:
e ^ (19 * r) = 200000/20000
e ^ (19 * r) = 10
19 * r = ln 10
r = ln 10/19
r = 0.1212
In other words, the rate of growth is 12.12%
Answer:
What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
Since a circle is simple it has no points but it can be folded many times so symmetry is really unlimited for the circle.It is not a plane because it is round and does not have sides.
The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
'The sum of the first and second integers exceeds the third by 32'
The third integer is 15 less than the first.
From Eqn 2:
Subtracting Eqn 1 from eqn 2
Dividing both sides by -2
Putting z=-10 in Eqn 3
Putting x=5 and z=-10 in Eqn 1
Hence,
The three integers are 5,17 and -10
