10x^2 - 25 = x^2
Take the square root of each side.
x = 10x - 5i
The answer is B. 3
It is the only value not attached to a variable, thus remaining constant.
Answer:
the second option
Step-by-step explanation:
The second option because there is no pattern.
Answer:
After 23 years , the capital will get three times as big
Step-by-step explanation:
Firstly, let us write the compound interest formula
P = I( 1 + r)^n
Since we are considering a capital rise of 3 times
If I, the initial value is x, the P
value later will be 3x
Interest rate is 5/100 = 0.05
so we need the value of t
This will be;
3x = x(1 + 0.05)^t
3= 1.05^t
ln 3 = t ln 1.05
t = ln 3/ln 1.05
t = 23 years
