The answer is 23. you take .4 and times it by the first number, then times it by that number until you have 10 numbers. then add all of those numbers up
Answer: 0.024
Step-by-step explanation:
percents are out of 100 so 2.4% divided by 100 = the decimal. 2.4/100 = 0.024
The sequence 1, 3, 6, 10, 15, etc find dy/dx...
dy/dx=2,3,4,5 this is not a constant so find d2y/dx2
d2y/dx2=1,1,1, this is a constant, specifically a constant acceleration, which is a property of a quadratic function of the form ax^2+bx+c and if we use three points of the sequence we can solve for all of the variables...
9a+3b+c=6
4a+2b+c=3
a+b+c=1 getting differences
5a+b=3
3a+b=2 and again
2a=1, so a=1/2, making 3a+b=2 become:
1.5+b=2, so b=1/2, making a+b+c=1 become
1/2+1/2+c=1 so c=0 so our function is:
a(n)=(n^2+n)/2
which can be expressed, if you factor the numerator as:
a(n)=n(n-1)/2
Alright, so you can try to study hard and gain a passing grade (A+) for the other two quarters.
