The binomial factors of the quadratic trinomial may take the forms of (y + a) and (y + b). The sum of a and b is equal to the numerical coefficient of the second term and their product should be equal to the constant. If a is equal to -2, b is equal to -8. Thus, the second factor is (y - 8).
The third one it could be one.
Answer:
D 3500
Step-by-step explanation:
This question is asking for the sum of all the terms in an arithmetic series.
So using the formula : Sn = n/2 (a+l) , where Sn is the sum of n terms, a is first term, and l is last term, we try to find Sn, with n being 25, a being 20, and an which is a25 or the twenty fifth term being 260, also being the last term.
Hence we can produce the formula for Sn which is Sn=25/2 (20+260)
Sn=25/2 (280)
=3500
Answer:
68.73%
Step-by-step explanation:
We have the insurance coverage amount for men of 30 years and for women of 50 years. Therefore, to find the percentage that represents the cost of coverage of the 50-year-old woman based on the cost of coverage of the man, we need to perform the following operation:
Where:
: cost of coverage for a woman of 50 years.
: coverage cost for a 30-year-old man.
Finally represents 68.73% of
