This is cross multiplication.
513.74 times x =513.74x
16.26 times 100=1626
Now there is 1626=513.74x
Do 1626 divided by 513.74 which is 3.16502511
Answer:
38
Step-by-step explanation:
This is the concept of commercial arithmetic, to solve for the time taken for loan of $548,048 to earn an interest of 50,000 given an interest rate of 9%. We use the formula:
A=P(1+r/100)^n
Where;
A=Future amount=548,048+50000=$598,048
P=principle
r=rate
n=time
thus;
598,048=548048(1+9/100)^n
1.0912=(1+0.09)^n
getting the logs of both sides
ln 1.0912=n ln1.09
thus
n=(ln 1.0912)/(ln 1.09)
n=1.01 years
The answer is 1 year
I can't help you with your graphing tool. With my graphing tool, the graph looks like this.
The vertex is at (-4, -1), and it goes through the point (-3, 1).
