Again, a spreadsheet or suitable calculator makes this short work.
The sum is 184.
_____
The terms being summed are ...
2·3² +3 = 2·9 +3 = 18 +3 = 21
2·4² +3 = 35
2·5² +3 = 53
2·6² +3 = 75
Their total is
21 +35 +53 +75 = 184
The total amount of interest will be found using compound interest formula:
A=p(1-r/100)^n
A=future amount
p=principle
r=rate
n=time
From the information given:
p=$6500, r=6%, n=25 years
thus
A=6500(1+6/100)^25
A=6500(1.06)^25
A=$27,897.16
Answer: 27897.12-6500=$$21397.2
calculating in? can u tell me more
Answer:
This is not a function
Step-by-step explanation:
Assuming that the line in question is parallel with the y axis, by using the line test we can see that the line is not a function. The line test is where you draw straight lines going vertically over the graph and if the lines touch the figure in question more than once that means it's not a function.
This can also be proved by imagining there are 2 different points on the line in question. Since the line is straight vertically that means that the points will share the same x value for different y values, which makes it not a function
