The answer is 1 2/3+4 2/5=91/15
Answer:
Hope It helps you :) Cause the graph haves to show two unsame activities
Step-by-step explanation:
x²-4x-5=0
The given equation is quadratic
So we can perform prime factorisation of it.
factors of -5, that add up to give -4 are -5 and 1
therefore replacing -4x by -5x+x
x²-5x+x-5=0
performing factoring by grouping,
(x²-5x)+(x-5)=0
x(x-5)+(x-5)=0
(x+1)(x-5)=0
x+1=0 and x-5=0
Answer is x=-1 and x=5
To solve this problem you must apply the proccedure shown below:
1. You must apply the following formula:
Where 
is the future value, 
is the present value, 
is the interest rate and 
is the time in years.
2. You have that the bank will double your money in 
years. Therefore:
3. Substitute values into the formula and solve for , as following:
4. By applying natural logarithm, you have:
%
The answer is: 
%
A is a binomial since it has only 2 values
